Terpaparrnya suatu zat dalam lingkungan sekarang ini dapat terjadi diberbagai jenis lingkungan. Salah satu zat yang dapat terpapar dalam suatu lingkungan adalah Hg atau biasa disebut merkuri. Merkuri merupakan unsur yang sangat jarang dalam kerak bumi, dan relatif terkonsentrasi pada beberapa daerah vulkanik dan endapan-endapan mineral biji dari logam-logam berat. Merkuri banyak terdapat di lingkungan terutama perairan. Adapun cara penelitian yang digunakan adalah cross sectional, yaitu penelitian untuk mempelajari dinamika korelasi antara faktor-faktor resiko dengan efek, dengan cara pendekatan pengumpulan data atau studi literature. Adapun hasil penelitian kondisi air sungai di wilayah pertambangan Cisoka pada tahun 2005 (< 0,05 x 10-3 ppm Hg), berada di bawah baku mutu air menurut Peraturan Pemerintah No. 82 Tahun 2001 (< 0,001 ppm), sedangkan pada tahun 2011, kadar Hg rata-rata berada di atas baku mutu air yaitu 0,00392 ppm. Akibat banyaknya merkuri yang terdapat di lingkungan dapat mengakibatkan air berubah menjadi warna keruh dan tercemar. Adapun Solusi untuk mengurangi merkuri di perairan yaitu dengan Penanggulangan (pengendalian dan pencegahan) dampak pencemaran dilakukan dengan penataan kembali tata ruang

3. Increasing development of Science and Technology (Science and
Technology) is currently triggering water pollution. Pollution of
heavy metals such as Mercury (Hg) can affect and cause etoksifikasi
(poisoning) that can damage the environment.
BACKGROUND
PURPOSE :
1. To determine the impact
analysis of risk exposure
Mercury substances to
the environment.
2. To determine the
relationship between
mercury and the
environment
PROBLEMS:
1. What is a Mercury (Hg)?
1. What is the impact of
exposure to the
substance Mercury (Hg)
to the water
environment?

4. Literature Review
MERCURY AND NATURE:
mercury (Latin: Hydrargyrum, silver water) is a chemical element in the periodic system
tables with symbol Hg and atomic number 80 and atomic weight of 200,59.
Mercury has properties as follows :
a. Shiny like metal, which is easy to divide themselves like little balls.
b. Evaporate at high heating
d. If evaporated leaving the rest and the heating is very high, should not leave a residue
that can be weighed
EXISTENCE AND USE OF MERCURY IN NATURE :
Mercury in nature are in three basic forms, namely: metallic mercury, inorganic
mercury and organic mercury . Toxifity depending on the form of mercury in nature.
Mercury is widely used in a variety of human activities, such as chlorine and soda
industries. Mercury is a kind of metallic, mercury can conduct electricity, so that the
mercury used in electronic devices.

5. Literature Review
QUALITY STANDARD OF MERCURY :
Food and Dung Administration (FDA) set a threshold of maximum mercury content of
0.0005 ppm to 0.5 ppm for water and food while World Healt Organisasion (WHO)
establishes maximum limits are lower at 0.0001 ppm for water.
The Indonesian government put limits through ambient quality standards and waste
set by the Government of the Republic of Indonesia with KEK-02/MENKLH/1/1998.
Water quality standards for class A and B maximum recommended mercury content
0.0005 ppm and the maximum allowed by 0.0001 ppm. the class C water maximum
allowable concentration of 0.0002 ppm, while group D of 0.0005 ppm.
IMPACT OF MERCURY :
Animals of the sea will be contaminated with methylmercury when the sea is
contaminated by mercury by drinking water or by eating other animals that contain
mercury, when the animal predators eat small organisms, they also bring the methyl
mercury in their bodies. This process is known as bioaccumulation and continued with
increasing levels of mercury. Predators such as fish have the highest position in the
chain of carrier mercury. When humans consume these fish then it will also be exposed
to mercury.

6. Literature Review
ANALYSIS AND HANDLING OF MERCURY
A variety of methods of analysis of mercury, that is :
1. ICP-MS (InductivelyCoupled Plasma Mass Spectrometry)
2. NAA (Neutron Activation Analysis)
3. CV-AAS (ColdVapor Atomic Absorption Spectrometry)
4. ASV (Anodic Stripping Voltammetry)
Various methods of analysis requires instruments that are expensive and also costs.
Therefore, it is not available at every institution, even though the agency actually
require in relation to the monitoring of waste.
Water pollution by mercury can not be solved simply by filtration, coagulation
copulation, precipitation, or the provision of alum. This is because mercury in the water
in ionic form. The best way to eliminate mercury in water is by ion exchange. Which
uses a resin capable of binding of mercury ions to become saturated, then regenerated
back with the addition of an acid, so that Mercury could be neutralized.

7. RESULTS

8. RESULTS

9. Based on Table 1, the condition of the river water in mining
areas Cisoka in 2005 (<0.05. 10 ppm Hg), is under the water
quality standards in accordance with Government Regulation
No. 82 of 2001 (<0,001 ppm), whereas in 2011, the average
Hg content was above the water quality standard is 0.00392
ppm.
This condition is likely caused by mining
activity increasing number of people when
compared to 2005. According to the British
Columbia Ministry of Environment (1989),
these values have shown the need for
remediation measures, especially Cisoka
mining area is an area for agriculture and
settlement (Table 3)
DISCUSSION

10. Conclusion
1. Analysis of metallic mercury can be carried out by
Method flame atomic absorption spectrometry (AAS) and
Neutron Activation Analysis Method.
2. Based on medical geology studies indicate that mercury
exposure in the media not only water, but also on
biomarkers such as food crops, vegetables and hair, the
average is still below the quality standard, however, in fish
and urine already exceeding the quality standards.
