The activity of using mercury in gold mining in Alue Baro Village, Meukek District is carried out freely so that it has a negative impact on the environment and the health of the miners. This study aims to determine the level of mercury in the hair of artisanal gold miners in Alue Baro village by referring to the reference that has been set by WHO. The data sample collection was carried out by taking 6 hair samples from the Alue Baro village gold miners who were selected with various types of work, namely gold processing, waste processing and waste waste until the time of the interview with a minimum working period of 1 year with sample codes R1, R2, R3, R4, R5 and R6 as control samples. The six samples were analyzed using Atomic Absorption Spectrophotometry equipped with a Mercury Analyzer which showed results, respectively, 1.01; 2.38; 1.65; 1.35; 1.66; and 0.64 ppm. The results of this study indicate that all hair samples have mercury levels above the mercury threshold that has been set by WHO, namely 1 ppm. High levels of mercury in hair samples were analyzed on exposure to mercury. Further research was conducted to analyze other metals contained in the hair of gold miners in Alue Baro village

<p>Gold amalgamation processes using mercury were practiced in small scale gold mining activities in Krueng Sabee, Aceh Province. Seafood (fish, mollusc, shrimp) and human hair samples were collected to assess mercury concentrations.  Acute and chronic toxicity symptoms which arise among the populations were observed as well as personal protective equipment used by gold miners. The range of mercury concentrations varied among fish, shrimp, and molluscs. The highest mercury levels were recorded in fish <em>Puntius latristriga</em> (172.299 ± 10.626 µg/g wet wt.), followed by mollusc, <em>Polymesoda caroliniana </em> (160,032 ± 0,522 µg/g wet wt.), fish <em>R.kanagurta</em> (149 ±2,000 µg/g wet wt.), shrimp <em>Penaeus monodon</em> (116.975 ± 4.807 µg/g wet wt.).  The variation of mercury concentrations in hair samples of 72 respondents were detected from 5.7 µg/g to 88.1 µg/g. The most frequent acute and chronic intoxication symptoms documented were headache, muscle cramps, cough, and aphthous ulcers. Personal protective equipment which has correlation with high mercury levels in gold miners were respirator/mask, gloves, and apparel (p &lt; 0.05). All seafood samples exceeded 0.5 µg Hg/g MoH Food and Drug Administrasion threshold level and hair samples over 10 µg/g as set by WHO tolerance limit.</p>

Gold processing by amalgamation produces gold amalgam and waste mercury. Poor mercury waste management can pollute the environment. Ilegal gold miners are often found in West Sumatra. In the process of gold processing always use Hg for the purification of the gold. This study aims to determine the level of mercury (Hg) in the gold miner's urine and see the long-working relationship. Mercury (Hg) is a heavy metal grouped into groups having high toxicity levels. The use of mercury (Hg) in the gold processing process can cause negative impact. Determination of mercury (Hg) with Atomic Absorption Spectrophotometer (SSA) method. The population of this research is gold miner worker in Nagari Koto Tuo Sijunjung as many as 3 people and also as sample. The instrument used in this research is a questionnaire and testing of urine specimen dilaboratorium with wet destruction method in research in.i Factors studied are the characteristics of r0espondents including age, and length of work. Sampling was done as much as 20 ml of urine. Urine sample examination was done at Laboratory by using Wet Destruction method. The result of mercury (Hg) examination in gold miner's urine was obtained by an average of 15.8 μg / l Mercury (Hg) in urine with a threshold of 4 μg / l. The benefit of this research is to provide an overview of the level of toxicity that occurs due to gold mining in illegal gold miners in Nagari Koto Tuo Sijunjung, West Sumatra.

One of the main daily consumer products in Peru is potato, but in recent years, the addition of agrochemicals with possible heavy metal content, such as cadmium (Cd) has decreased the quality of the final product resulting in a negative impact on soils. The objective of this study is to determine the concentration of Cd in cultivation areas and in potato plantations. For this purpose, 6 tuber samples, 6 leaf samples, as well as 6 samples of agricultural soil used for cultivation were taken. Subsequently, the concentrations of Cd were evaluated by atomic absorption spectrophotometry, and the results were subjected to variance analysis and mean comparison test (Tukey p<0.05). Soil analysis for Cd shows that 50% of samples are not suitable for agricultural use, with concentrations reaching 3.99 mg kg−1 Cd; 83% of tuber samples pose a health risk, exceeding the Maximum Allowable Limits (0.1 mg kg−1) set by the Codex Alimentarius; and in the case of the leaves as a whole they have alarming levels of Cd, exceeding 2 mg kg−1.

During the existence of the traditional gold mining in the Mersak Village subdisdtrict of Central Kluet district South Aceh has been a lot changes in local community life. The research methodology used is descriptive method with qualitative approach. Data collection techniques used were interviews, observation, and literature study. Informants in this study consisted of village officials, community leaders and the community of gold miners. Data analysis technique used is the technique of interactive analysis by Milles and Huberman form of data reduction, data presentation and verification / conclusions. The results of the research tells us that the existence of gold mines in the Village Ruin has an impact on the social and economic condition of the community. Negative impact on the gold mining aspects of uncontrolled population movements and worrying, the incidence rate is increasing conflict and transition people's livelihood of farmers to miners who create agricultural infrastructure is not functioning optimally. Also, positive impact on the gold mining aspects of the comprehensive work opportunities for people and rising incomes that can be seen from the high purchasing power. Keywords: Mining, Impact, Social, Economic

The aim of this study was to evaluate the effect of supplementation with an organic form of manganese on its concentration in blood, hair, and organs of goat kids. A total of 27 kids were divided into control and experimental groups on the day of their birth (Day 1). The kids were on mother’s milk only diet until the day of weaning (Day 70). After weaning the kids received pellets at doses 0.3 kg/head/day for next 70 days. The control group received pellets (manganese content 36.7 mg/kg) and the experimental group received pellets with extra manganese addition in the form of manganese proteinate at the amount of 220 mg/kg. Blood samples were taken on days 1, 70, 105, and 140; hair samples on days 1, 70, and 140. At the end of experiment, 7 kids from each group were slaughtered and samples of heart, liver, spleen, pancreas, kidney, muscle, and brain were taken. Manganese concentration was determined from fresh tissues after microwave digestion by electrothermal atomic absorption spectrophotometry. Kids of the experimental group had a significantly higher manganese concentration in the liver (4.90 vs. 3.06 mg/kg), heart (0.47 vs 0.28 mg/kg), kidney (1.29 vs. 0.87 mg/kg), brain (0.33 vs 0.26 mg/kg), and hair (4.25 vs. 3.14 mg/kg) compared to the control group. The manganese concentration in blood was not affected by supplementation. Results of this study indicate that using the mentioned organs and hair for evaluation of the manganese status in an organism is more suitable than the determination of manganese concentration in blood.
