There was an exceptional hike in the gold prices experienced in The local demand for gold in India has always been ona rise. the country in the 1970s which further led to extensive gold According to national survey data there are only three mining for a very long period. functioning gold mines in India namely Hirabuddini mines in Jharkhand, and Hatti, Uti gold minesinKarnataka.1 Arsenic also serves as an important constituent of gold mining. It has a low abundance in the earth’s crust so it exists in the The village of Hutti is located in Raichur District in the Indian form of sulfide bearing minerals. The mining of gold and base state of Karnataka. This mine is probably one of the most metals is associated with sulfide mineralization thus ending up ancient metal mines in the world. There was an extensive releasing arsenic in the environment.6 increase in gold mining in the area between 1890 and 1920. The industry closed down in 1920 due to technical difficulties Hg and As are known toxicants that are hazardous to humans, and lack of funds. After the end of the second world war, the wildlife and domestic animals and may accumulate in the production started in September 1948, at the rate of 130 tonns environment causing serious damage to ecosystems and human of ore per day. By 1972 this rate had progressively increased to health. Studies conducted throughout the world where gold 600 tonnes of ore per day.2 The Company was originally mining occurs have reported the presence of high mercury and formed in 1947 as the Hyderabad Gold mines Company Ltd., arsenic concentrations in human urine, breast milk, blood,hair, 7 with the Hyderabad State Government holding a majority of and nails, and in plant and fish samples. the shares.

Of the mother. Thus, even a woman with a low level of mercury hundred participants who participated in the survey, 39% lived exposure could give birth to a child with significant birth in Hutti for more than ten years, and 34% lived in the area for defects.7 In addition, Hg exposure due to transmission through five to ten years, remaining 27% lived for less than five years. breast milk could have an effect on the healthy development of Hutti village was the main center for mining activities in infants.8 Finally, infants and children are sometimes directly Raichur. Amongst the study population, the proportion of exposed to the mining processes themselves, since mothers participants who were aware of the gold mining were 81% and often have their children at the mine site and processing areas rest were unaware of the activity. while they are working and sometime young children even Most of the people who participated (67%) in the survey were 9 participate in mining as workers. aware of the ill effects of mining.

The primary objective mining and its byproducts are known to cause lots of health of this survey was to assess community risk knowledge and issues. In growing age these signs and symptoms are more perception of potential Mercury and Arsenic toxicity and/or pronounced than elders. So the next question was to see the exposure from artisanal gold mining in the Hatti village frequency of children taking leave from school due to health locality. issues. 50% and 39% children took leave from school once a month and more than once a month respectively.
