[BBG01-P01] Human Health Risk Assessment due to Aquifer Nitrate concentration of Laksar block of District Haridwar, Uttarakhand, India
キーワード：Ground Water , Human Health Risk Assessment , Nitrate pollution
Groundwater contamination by nitrate is a matter of global concern and reactive nitrogen is a widespread contaminant of ground and surface water bodies worldwide. The groundwater of Block laksar district Haridwar district is mainly contaminated by nitrate-nitrogen. Nitrate contamination associated with N-based fertilizers use, geology of sub-surface, pit latrines, sewerage,
industrial effluents, and manure storage. The study aims to investigate the possible healthnhazards in local residents of Haridwar, Uttarakhand, India due to presence of high nitrate inbthe groundwater of study area. Amount of nitrate in ground water of Haridwar region in ranges between 0.1 - 89mgL -1 . Some locations showed the high level of nitrate than the safenlimits as decided by the Bureau of Indian standards (higher than 45 mgL -1 ) and World Health Organization (50 mg L -1 ). There is a strong and direct relation between drinking water nitrate ingestion and associated health risks like methemoglobinemia (Blue baby syndrome) among infants and specific type of cancer. The crude current rate of cancer in Uttarakhand is 91(incident rate per 100000 in 2016). Nearly 59 deaths are reported due to cancer only in Haridwar district during the year 2018-19. People who consume high nitrate have a higher risk of Cardio Vascular Disease, Inflammatory Arthritis and enlargement of Thyroid gland.
The study tends to show that the people of block laksar Haridwar district are at risk of chronic toxicity due to excess intake of nitrate in drinking water. Therefore, this is call to take some immediate preventive measures to safeguard the health of local residents.
