This document discusses various sources of toxicity in the environment and consumer goods. It provides information on the prevalence of toxic chemicals used commercially and approved for foods. Several statistics are presented showing the widespread detection of chemicals in human samples. Common sources of toxins discussed include air pollutants, chemicals, and heavy metals. Specific chemicals like benzene, formaldehyde, and pesticides are examined in more detail regarding their sources and health effects.
5. Toxicity
Toxic exposure is unavoidable and exceeds the body's natural ability to remove toxic waste.
The EPA estimates over 70,0000 chemicals are used commercially for agriculture, building
materials and consumer goods.
3,000 chemicals are approved for use in our food directly.
Over 10,000 chemicals are used in food processing, preserving and storage.

6. Toxicity
From 1999-2004 the Center for Disease Control and Prevention (CDC) found 219 different
chemicals in blood and urine; 75 were never seen before.
From, 2007-2008, the Environmental Working Group (EWG) research detected 287 chemicals
in the umbilical cord blood of newborns.
Of that total, 180 are known to cause cancer in humans or animals, 217 are toxic to the brain
and nervous system and 208 cause birth defects or abnormal development.
6
7. Toxicity
In 2009 the Fourth National Report on Human Exposure to Environmental Chemicals was released.
The Fourth Report includes results for 75 chemicals measured for the first time in the U.S.
population.
These chemicals are in the following groups:
Acrylamide and glycidamide adducts
Arsenic species and metabolites
Environmental phenols, including bisphenol A and triclosan
Perchlorate
Perfluorinated chemicals polybrominated diphenyl ethers
Volatile organic compounds
Some additions to chemical groups previously measured
7
8. Toxicity and Disease
Environmental toxicity continues to worsen with each generation.
The bioaccumulation of toxins has caused a new era of sickness, illness, and disease.
Columbia University School of Public Health reports that 95% of cancer is caused by diet and
the accumulation of toxins.
8
10. Toxic Symptoms and Health Effects
Physical symptoms: fatigue, headache, stress, joint and muscle pain, frequent colds and flu,
allergies, hormone imbalance, chemical sensitivity, cold hands and feet, psoriasis and other
skin conditions, insomnia, dark circles under the eyes, depression and anxiety.
Psychological symptoms: poor concentration, memory loss, mood changes, mental confusion,
brain fog and changes in behavior.
All of these toxic symptoms are directly associated with MCS, Chronic Fatigue, Lyme,
Diabetes, Obesity, Osteoporosis, Cancer and autoimmune diseases.
These diseases are direct results of living in a world overrun with toxins, chemicals, heavy
metals and environmental byproducts.

Indoor sources
"Major" sources are defined as sources that emit 10 tons per year of any of the listed toxic air
pollutants, or 25 tons per year of a mixture of air toxics. These sources may release air toxics
from equipment leaks, when materials are transferred from one location to another, or during
discharge through emission stacks or vents
“Area” sources emit less than 10 tons per year of a single air toxic, or less than 25 tons per
year of a combination of air toxics.
18

Sources: industrial solvents, synthetic intermediates, and solvents in commercial products such as
paints, coatings, adhesive removers, and paint thinners; polystyrene cups, cleaners, paper, smog,
groundwater; they are also a component of gasoline; occurs naturally in petroleum and coal tar and is
formed during forest fires
Effects: primary effects of xylene exposure involve the nervous system by all routes of exposure, the
respiratory tract by inhalation exposure, and, at higher oral exposure levels, hepatic, renal, and body
weight effects; dermal exposure of humans to xylene causes skin irritation, dryness and scaling of the
skin, and vasodilation.
The nervous system effects include subjective symptoms of intoxication at higher concentrations
and impaired performance on tests of short-term memory, reaction time, and equilibrium at lower
concentrations.
63
65. Heavy Metals
“Heavy Metals": antimony, arsenic, bismuth, cadmium, cerium, chromium, cobalt, copper, gallium,
gold, iron, lead, manganese, mercury, nickel, platinum, silver, tellurium, thallium, tin, uranium,
vanadium, and zinc
Small amounts of these elements are common in our environment and diet and are actually
necessary for good health; large amounts of any of them may cause acute or chronic toxicity
(poisoning).
Heavy metal toxicity can result in damaged or reduced mental and central nervous function, lower
energy levels, and damage to blood composition, lungs, kidneys, liver, and other vital organs. Long-
term exposure may result in slowly progressing physical, muscular, and neurological degenerative
processes that mimic Alzheimer's disease, Parkinson's disease, muscular dystrophy, and multiple
sclerosis. Allergies are not uncommon, and repeated long-term contact with some metals (or their
compounds) may cause cancer
65
67. Heavy Metal: Mercury
Mercury is a powerful metal, more toxic than lead, cadmium, and arsenic.
Mercury is a naturally occurring element that is found in air, water and soil.
When mercury is released from industries into the air, it can travel long distances and be
deposited on soil and in lakes where small organisms change the mercury to a form of organic
mercury (methylmercury) that builds up in the bodies of fish.
Metallic mercury has been found at 714 hazardous waste sites nationwide.
Exposure Routes: inhalation, drinking and eating, touching
67
69. Heavy Metal: Mercury
3 Forms of Mercury
Methylmercury:
Organic form of mercury and the form of mercury that is most easily bioaccumulated in organisms; leads to high
concentrations in predatory fish, which, when consumed by humans, can result in an increased risk of adverse
effects in highly exposed or sensitive populations
Elemental or Metallic Mercury
A major source of exposure for elemental mercury is through inhalation in occupational settings.
Another source of exposure to low levels of elemental mercury in the general population is elemental mercury
released in the mouth from dental amalgam fillings
Exposures can occur when elemental mercury is spilled or products that contain elemental mercury break and
expose mercury to the air, particularly in warm or poorly-ventilated indoor spaces.
Inorganic or Organic Mercury Compounds
Limited exposure could occur through the use of old cans of latex paint, which until 1990, could contain mercury
compounds to prevent bacterial and fungal growth
69
70. Heavy Metal: Mercury
Methylmercury Health Effects
For fetuses, infants, and children, the primary health effect of methylmercury is impaired neurological
development.
Impacts on cognitive thinking, memory, attention, language, and fine motor and visual spatial skills
have been seen in children exposed to methylmercury in the womb.
Exposure to high levels of mercury (Hg) can cause neurologic and kidney disorders
70
72. Heavy Metal: Mercury
Elemental Mercury Health Effects
causes health effects when it is breathed as a vapor where it can be absorbed through the lungs
Symptoms include these: tremors; emotional changes (e.g., mood swings, irritability, nervousness,
excessive shyness); insomnia; neuromuscular changes (such as weakness, muscle atrophy, twitching);
headaches; disturbances in sensations; changes in nerve responses; performance deficits on tests of
cognitive function.
At higher exposures there may be kidney effects, respiratory failure and death.
72
73. Heavy Metal: Mercury
Elemental Mercury Vapor, “Smoking Teeth”
Elemental mercury is a heavy, shiny, silver-white, odorless liquid. It is nonflammable, but releases toxic
vapor, especially when heated. Odor does not provide any warning of hazardous concentrations.
Inhalation is the primary route of exposure to elemental mercury vapor or aerosols, which are readily
absorbed. Virtually no elemental mercury is absorbed from the gastrointestinal tract or by the skin.
Mercury crosses the placenta and can be transferred to infants via breast milk.
Inhalation of mercury vapor is the primary route of exposure to elemental mercury. Inhaled vapor is almost
completely absorbed by the lungs (75-80%). Neither liquid mercury nor mercury vapor has an odor
Mercury vapor is heavier than air and may therefore accumulate in poorly ventilated or low-lying areas
73
74. Heavy Metal: Mercury
Inorganic and Organic Compound Mercury Health Effects
High exposures to inorganic mercury may result in damage to the gastrointestinal tract, the nervous
system, and the kidneys.
Both inorganic and organic mercury compounds are absorbed through the gastrointestinal tract and
affect other systems via this route.
Symptoms of high exposures to inorganic mercury include: skin rashes and dermatitis; mood swings;
memory loss; mental disturbances; and muscle weakness. People concerned about their exposure to
inorganic mercury should consult their physician.
74
75. Heavy Metal: Mercury
Additional Health Effects
The major route of exposure to elemental mercury is inhalation of mercury vapor. Symptoms of acute
toxicity following high-level exposure to mercury vapor occur within hours of the exposure.
Respiratory symptoms include corrosive bronchitis with fever chills and dyspnea, which can progress
to pulmonary edema or fibrosis. Abdominal cramps, diarrhea, renal dysfunction, visual disturbances,
and central nervous system damage leading to neuropsychiatric disturbances and intention tremors
may also occur.
Mercury can cross the blood-brain and placental barriers. It is also excreted in breast milk. Children
may be at increased risk for pulmonary toxicity and are more likely to develop respiratory failure.
75
77. Heavy Metal: Lead
Lead occurs naturally, but much of its presence in the environment stems from its historic use
in paint and gasoline and from ongoing or historic mining and commercial operations.
The past use of lead in gasoline and paint can result in high lead levels in soil.
Lead is still used widely in commercial products and accumulates in the environment.
The body absorbs organic lead (as was used in leaded gasoline and is used in occupational
settings) faster than inorganic lead and reacts easily with acids, alkalis, and other chemicals.
77
78. Heavy Metal: Lead
Sources
Inorganic Lead
Old paint, soil, pipes, packages or storage containers, production sources, mining, smelting, workplaces
Leaded gasoline exhaust contributed to ambient inorganic lead contamination.
Organic Lead.
Leaded gasoline contained organic lead before it was burned; however, since the elimination of lead from gasoline in
the U.S. starting in 1976, exposure to organic lead is generally limited to an occupational context.
Organic lead can be more toxic than inorganic lead because the body more readily absorbs it.
Potential exposures to organic lead should be taken very seriously.
78
79. Heavy Metal: Lead
Sources
Homes and Buildings: paint, pipes
Water: pipes, faucets, solder, plumbing
Food and Beverages: production, processing, packaging, storage, uptake from soil, atmospheric lead
deposition into leafy vegetables, grinding or cutting equipment during processing, some pottery and
ceramics, certain ‘natural’ calcium supplements, certain imported candies
Commercial Products: automotive batteries, bridge paint, computers, jewelry, pewter, ceramic glaze
Natural Environment: mines, smelters, waste sites, small garages, dust and soils
Workplaces: battery manufacturing plants, construction in housing renovation and rehabilitation, rubber
products and plastics, soldering, steel welding and cutting, bridge maintenance and repairs, municipal
waste incinerator workers, radiator repair mechanics,
pottery and ceramics industry employees
79
80. Heavy Metal: Lead
Lead Exposure
Most human exposure to lead occurs through ingestion or inhalation.
Lead exposure is a global issue. Lead mining and lead smelting are common in many countries, where
children and adults can receive substantial lead exposure
Lead paint is a primary source of environmental exposure to lead. Lead may be released from old
paint in home environments if the paint is disturbed (e.g., renovation), deteriorated (peeling,
chipping, and chalking), or subject to friction or impact (doors, windows, porches, etc…).
Workers in many industries (and secondary exposure to their families) may have occupational
exposure to lead.
Contaminated drinking water, food, alcohol, and home remedies are sources of environmental
exposure to lead.
80
82. Heavy Metal: Lead
Lead Health Effects
Absorbed lead that is not excreted is exchanged primarily among three compartments:
Blood
Mineralizing tissues (bones and teeth), which typically contain the vast majority of the
lead body burden
Soft tissue (liver, kidneys, lungs, brain, spleen, muscles, and heart)
Lead toxicity affects every organ system
82
83. Heavy Metal: Lead
Lead in the Blood
Although the blood generally carries only a small fraction of total lead body burden, it does serve as
the initial receptacle of absorbed lead and distributes lead throughout the body, making it available to
other tissues (or for excretion).
The half-life of lead in adult human blood has been estimated to be from 28 days to 36 days.
Approximately 99% of the lead in blood is associated with red blood cells; the remaining 1% resides in
blood plasma.
In addition, the higher the lead concentration in the blood, the higher the percentage partitioned to
plasma. This relationship is curvilinear –as blood lead levels (BLLs) increase as the high-end plasma
level increases more.
83
85. Heavy Metal: Lead
Lead Mineralizing Tissues (Bones and Teeth)
Mineralizing tissues (bones and teeth), which typically contain the vast majority of the lead body
burden
The bones and teeth of adults contain about 94% of their total lead body burden; in children, the
figure is approximately 73%.
Lead in mineralizing tissues is not uniformly distributed. It tends to accumulate in bone regions
undergoing the most active calcification at the time of exposure
85
86. Heavy Metal: Lead
Lead Neurological Effects
The nervous system is the most sensitive target of lead exposure.
There can be a difference in neurological effects between an adult exposed to lead as an adult, and an
adult exposed as a child when the brain was developing.
Childhood neurological effects, including ADHD, may persist into adulthood. Lead-exposed adults may
also experience many of the neurological symptoms experienced by children, although the thresholds
for adults tend to be higher.
Effects Include: decreased libido, depression/mood changes, headache, diminished cognitive performance,
diminished hand dexterity, diminished reaction time, diminished visual motor performance, dizziness,
impotence, increased nervousness, irritability, lethargy, malaise, paresthesia, weakness, fatigue,
forgetfulness
86
87. Heavy Metal: Lead Poisoning Symptoms

89. Heavy Metal: Cadmium
Cadmium, a heavy metal, is produced by refining zinc ores.
Cadmium metal is practically insoluble in water but some cadmium salts are water soluble.
Powdered cadmium will burn and can release corrosive fumes
Cadmium, a rare but widely dispersed element, is found naturally in the environment. Most
cadmium ore (greenockite):
exists as cadmium sulfide,
is refined during zinc production, and
occurs in association with zinc
It is released into the environment through mining and smelting, its use in various industrial
processes, and enters the food chain from uptake by plants from contaminated soil or water.
89
90. Heavy Metal: Cadmium
Cadmium Sources
Cadmium has been widely dispersed into the environment through the air by its mining and smelting as
well as by other manmade routes:
Usage of phosphate fertilizers
Presence in sewage sludge
Various industrial uses such as NiCd batteries, plating, pigments and plastics
Industrial Processes
The most important sources of airborne cadmium are smelters. Other sources of airborne cadmium
include burning fossil fuels such as coal or oil and incineration of municipal waste such as plastics and
nickel-cadmium batteries. Cadmium also escapes into the air from iron and steel production facilities.
Cadmium is used mainly in metal plating, in producing pigments, in NiCad batteries, as stabilizers in
plastics, and as a neutron absorbent in nuclear reactors.
90
92. Heavy Metal: Cadmium
Cadmium Health Effects
The most sensitive targets of cadmium toxicity are the kidney and bone following oral exposure and
kidney and lung following inhalation exposure.
The effects observed in humans include renal tubular damage, glomerular damage, decreases in bone
mineralization, increased risk of bone fractures, decreased lung function, and emphysema. These effects
typically occur after long term exposure to cadmium.
Some studies have cadmium workers have found increases in the risk of lung cancer.
DHHS and IARC consider cadmium to be a human carcinogen. EPA considers cadmium to be a probable
human carcinogen by the inhalation route.
92
95. Heavy Metal: Arsenic
Arsenic is a naturally occurring element widely distributed in the earth's crust.
In the environment, arsenic is combined with oxygen, chlorine, and sulfur to form inorganic
arsenic compounds.
Arsenic in animals and plants combines with carbon and hydrogen to form organic arsenic
compounds.
Inorganic arsenic compounds are mainly used to preserve wood.
95
97. Heavy Metal: Arsenic
Sources:
Ground water, mineral ore, geothermal processes
Arsenic cannot be destroyed in the environment; it can only change its form or become attached to or
separated from particles.
Arsenic attached to very small particles may stay in the air for many days and travel long distances.
Arsenic in soil may be transported by wind or in runoff or may leach into the subsurface soil. Arsenic is
largely immobile in agricultural soils, therefore, it tends to concentrate and remain in upper soil layers
indefinitely.
Transport and partitioning of arsenic in water depends upon the chemical form. Soluble forms move
with the water and may be carried long distances. Arsenic may be adsorbed from water onto
sediments or soils.
97
99. Heavy Metal: Arsenic Health Effects
Inhalation of inorganic arsenic may cause respiratory irritation, nausea, skin effects, and increased risk of
lung cancer.
Acute high dose oral exposure to inorganic arsenic may cause nausea, vomiting, diarrhea, cardiovascular
effects and encephalopathy.
Long term oral exposure to low levels of inorganic arsenic may cause dermal effects (such as
hyperpigmentation and hyperkeratosis, corns and warts) and peripheral neuropathy characterized by a
numbness in the hands and feet that may progress to a painful “pins and needles” sensation. There may
also be an increased risk of skin cancer, bladder cancer, and lung cancer.
Oral exposure to MMA may result in gastrointestinal damage. Kidney effects may be observed following
chronic exposure.
Chronic oral exposure to DMA may result in urinary bladder and kidney effects.
99
101. Heavy Metal: Copper
Copper is an essential element in plants and animals (including humans), which means it is
necessary for us to live.
Plants and animals must absorb some copper from eating, drinking, and breathing.
Copper compounds are commonly used in agriculture to treat plant diseases like mildew, for
water treatment and, as preservatives for wood, leather, and fabrics.
101
102. Heavy Metal: Copper
Source
Copper is a metal that occurs naturally throughout the environment, in rocks, soil, water, and air.
Copper is used to make many different kinds of products like wire, plumbing pipes, and sheet metal.
Copper is also combined with other metals to make brass and bronze pipes and faucets.
102
103. Heavy Metal: Copper
Health Effects
Everyone must absorb small amounts of copper every day because copper is essential for good health.
High levels of copper can be harmful.
Breathing high levels of copper can cause irritation of your nose and throat.
Copper toxic symptoms: nausea, vomiting, fever, diarrhea, low blood pressure, anemia, and heart problems
Very-high doses of copper can cause damage to your liver and kidneys, and can even cause death.
103
104. Heavy Metal: Aluminum
Aluminum is a silvery-white metal. In nature it is found in soil, rocks (particularly igneous rocks),
and clays as aluminosilicate minerals.
Aluminum is the most abundant metal in the earth’s crust.
Due to high reactivity, aluminum does not exist as the metal in the environment; it exists in a
combined state with other elements.
Aluminum cannot be destroyed in the environment. It can only change its form or become attached
to or separated from particles.
104
105. Heavy Metal: Aluminum
Sources:
Aluminum metal is used to make a variety of products including beverage cans, pots and pans, automotive
components, siding and roofing, and foil.
Aluminum compounds are used in diverse industrial applications including water treatment, abrasives, and
furnace linings. Powdered aluminum metal is used in explosives and fireworks.
Aluminum compounds are also used in consumer products such as foil and antiperspirants, over the counter
and prescription drugs such as antacids, buffered aspirin and in food additives.

106. Heavy Metal: Aluminum
Exposure
Consumption of food (mainly processed foods), water, and aluminum containing medicinals, such as
antacids, buffered analgesics, anti-diarrheal agents, or anti-ulcerative medication.
Refining of the primary metal and in secondary industries that fabricate aluminum products (such as aircraft,
automotive, and metal products) and aluminum welding.
Routes of Exposure
Oral – primary route of exposure for the general population. Aluminum is found in food, drinking water, and
medicinal products such as antacids and buffered aspirin.
Dermal (skin) contact – minor route of exposure; aluminum is found in some topically applied consumer
products such as antiperspirants, first aid antibiotics, and sunscreen and suntan products.
Inhalation – generally limited to occupational exposure

107. Heavy Metal: Aluminum
Health Effects
The most sensitive target of aluminum toxicity is the nervous system. Impaired performance on
neurobehavioral tests of motor function, sensory function, and cognitive function have been observed in
animals. Neurobehavioral alterations have been observed following exposure of adult or weanling animals
and in animals exposed during gestation and/or lactation.
Respiratory effects, such as impaired lung function and fibrosis have been observed in aluminum workers.
Aluminum-containing over the counter medications such as antacids and buffered aspirin are assumed to be
safe in healthy people at recommended doses based on historical use. There is some indication that skeletal
effects (e.g., osteomalacia) can result from long-term use in some individuals.

109. Heavy Metal: Chromium
Chromium exists in three common stable valence states: chromium (0), (III), and (VI).
Cr(III) is an essential dietary nutrient. Its deficiency in the body has been associated with diabetes,
infertility, and cardiovascular disease.
Hexavalent Chromium - Cr(VI) is carcinogenic.
Chromium is one of the most widely used industrial metals.
The metallurgical, chemical, and refractory industries are the fundamental users of chromium.
It is one of the major contaminants in various hazardous waste sites worldwide, including the
Superfund sites in the United States
109
110. Heavy Metal: Chromium
Sources:
Naturally occurring chromium is usually present as trivalent Cr(III).
Hexavalent Cr(VI) in the environment is almost totally derived from human activities
AIR: According to the Toxics Release Inventory, in 1997, the estimated releases of chromium were 706,204
pounds to the air from 3,391 large processing facilities which accounted for about 2.2% of total environmental
releases.
WATER: According to the Toxics Release Inventory, in 1997, the estimated releases of chromium was 111,384
pounds to water from 3,391 large processing facilities which accounted for about 0.3% of total environmental
releases.
SOIL: According to the Toxics Release Inventory, in 1997 the estimated releases of chromium was 30,862,235
pounds to soil from 3,391 large processing facilities accounted for about 94.1% of total environmental releases
Total chromium has been identified in 939 soil and 472 sediment samples collected from 1,036 National Priority
Lists.

Hexavalent Chromium Found in 31 U.S. Cities
In 2010, the Environmental Working Group did a
study of U.S. tap water and found hexavalent
chromium in 31 of 35 cities tested. The levels in
all 31 cities exceeded the public health goal for
hexavalent chromium.
California EPA has determined that hexavalent
chromium is a likely carcinogen in drinking water.
This graph represents the amounts of chromium
in each city by surface area.
112. Heavy Metal: Chromium
Exposure
Chromium is one of the most widely used industrial metals. Several million workers worldwide are
estimated to be exposed to chromium compounds in an array of industries such as pigment production,
chrome plating, stainless steel welding, and leather tanning. Additionally, it is one of the major contaminants
in various hazardous waste sites worldwide, including the Superfund sites in the United States.
The general population is exposed to chromium by inhaling ambient air, ingesting food, and drinking water
containing chromium.
The presence of chromium compounds at hazardous waste sites can contribute to the exposure of
populations residing or working nearby such sites. These populations may be exposed through to air
containing particulates or mists of Cr(VI) compounds, through drinking water if soluble forms of Cr(VI) leach
into groundwater, or through skin contact with soil at hazardous waste sites.
112
114. Heavy Metal: Chromium
Health Effects:
In general, chromium(VI) compounds are more toxic than chromium(III) compounds.
The most sensitive targets of chromium(VI) are the respiratory (nasal and lung irritation and altered
pulmonary function following inhalation exposure), gastrointestinal (irritation, ulceration, and stomach and
small intestine lesions following oral exposure), hematological (microcytic, hypochromic anemia), and
reproductive (decreased sperm count and epididymal damage) systems.
The primary targets of chromium(III) compounds are the respiratory (following inhalation exposure) and
immunological systems. Chromium allergic dermatitis is typically elicited by dermal contact in sensitized
individuals.
DHHS, IARC, and EPA have classified hexavalent chromium(VI) as a human carcinogen.
IARC has classified chromium(III) and metallic chromium as not classifiable as to their carcinogenicity to
humans.

116. Far Infrared
Inside the electro-magnetic spectrum, Far Infrared heat is manufactured by the sun.
It is a portion of the sun’s invisible band. Even though the band of light is not detectable to the human eye, the
heat sensation is felt. In addition, infrared energy is also produced as body heat.
Far Infrared energy heats things by direct, molecular excitation, without heating the air between the spaces. Far
Infrared rays infiltrate the body’s tissue much deeper than near infrared rays do.
The body absorbs Far Infrared heat waves that encourage the transfer of water across cellular membranes.
Once this happens, and the cellular membranes are hydrated, the blood flow is enhanced and ultimately assists
with an assortment of biologically beneficial healing functions.
116
118. Far Infrared
The most notable characteristic of Far Infrared heat is its exceptional ability to penetrate far below superficial
skin layers.
When this occurs, it constructs a natural resonance, which has numerous advantageous properties.
Infrared energy is measured in wavelengths as microns, and the human body can best absorb infrared energy in
the 3- to 50-micron range—with the best absorption occurring at 9.4 microns (the same as the human body).
These rays penetrate deep into the body where they gently elevate the body’s surface temperature and assist in
expanding capillaries which stimulates blood circulation.
By elevating the sub-surface tissue temperature, a series of continual changes constructive to human health will
be instigated.
118
119. FIR Resonant Absorption
"These rays are selectively absorbed by the tissues. The internal production of infrared energy
that normally occurs within our tissues is associated with a variety of healing responses and
may require a boost to a maximal level to insure the fullest healing response possible in a tissue
under repair. After boosting a tissue's level to maximum, the remaining rays pass onward
harmlessly. This phenomenon is called Resonant Absorption."

121. Far Infrared Detoxification
FIR mobilizes toxins from lipid cells and excrete via perspiration
Invisible waves of energy absorbed by the tissues, muscles, tendons, bones
Detoxification at the cellular level
Significant benefits throughout entire body
FIR therapy used with the ‘Brimhall Six Steps to Wellness Program’ will lead to healthier patients,
and better patient results.
