ARSENICOSIS
Arsenicosis is a chronic health condition caused by prolonged exposure to elevated levels of arsenic in drinking water, food, or air. It results from the accumulation of arsenic in the body over time, leading to various health complications and diseases.
Causes:
- Natural Geologic Sources: Arsenic occurs naturally in the earth's crust and can leach into groundwater from geological formations containing arsenic-rich minerals, such as arsenopyrite.
- Human Activities: Anthropogenic activities, such as mining, industrial processes, and the use of arsenic-containing pesticides and fertilizers, can contribute to the contamination of soil and groundwater with arsenic.
- Poor Water Management: Inadequate water management practices, such as excessive pumping from aquifers or improper disposal of industrial waste, can exacerbate arsenic contamination in groundwater.
- Microbial Activity: Microbial processes in aquifers, such as the reduction of arsenic-bearing minerals by bacteria, can release arsenic into groundwater under certain environmental conditions.
Effects:
- Health Impacts: Arsenicosis can lead to a range of health effects, including skin lesions, pigmentation changes, peripheral neuropathy, cardiovascular diseases, respiratory issues, and various types of cancers (e.g., skin, lung, bladder).
- Social and Economic Burden: Arsenicosis imposes a significant social and economic burden on affected individuals, families, and communities due to healthcare costs, loss of productivity, and decreased quality of life.
- Environmental Degradation: Arsenic contamination in groundwater can have adverse effects on ecosystems and biodiversity, disrupting natural habitats and contaminating surface water bodies through groundwater discharge or leaching.
Occurrences and Examples from Hyderabad, India, and Other Parts of India:
- West Bengal: One of the most well-known examples of arsenic contamination in India is the groundwater in parts of West Bengal, where millions of people are at risk of arsenicosis due to high levels of arsenic in drinking water wells.
- Bihar: Several districts in Bihar, including Bhojpur and Buxar, have reported cases of arsenicosis due to arsenic-contaminated groundwater sources.
- Uttar Pradesh: Arsenic contamination has also been documented in certain regions of Uttar Pradesh, such as the Gangetic plains, where groundwater arsenic levels exceed permissible limits, posing risks to public health.
- Hyderabad, Telangana: While arsenic contamination is not as prevalent in Hyderabad compared to other parts of India, localized instances of arsenic contamination in groundwater may occur due to industrial activities or natural geological sources in specific areas.
Arsenicosis poses significant health risks and challenges for water supply engineering and public health efforts in India. Addressing arsenic contamination requires comprehensive strategies for water management, monitoring, and treatment to ensure access to safe and arsenic-free drinking water for all communities.
