Mercury contamination from pulp cum paper mill untreated effluent and solid waste in India: a review.

Mukesh Kumar Ahirwar

Mercury is a major toxic pollutant that is transported over long distances and can bioaccumulate and contaminate. Currently, solid waste of coal fuel and paper mill effluent that emits most to atmospheric Hg and has the high ratio in the industrial outlet. Near the paper mill environment mercury is generally elevated, particularly in effluent, air and water bodies in India. We have selected 20 paper mills and take reference from Google web to finding concentration of mercury. Untreated paper mill effluent and their air spread in local environment and remote areas elevate the concentration of mercury compared than other places of clean environment. Large river estuaries in the world are often heavily affected by upstream industrial effluents. Mercury is also elevated in mud of paper mill effluent, sediments, a direct result of contamination in river systems. Solid waste of paper mill contained high concentration of mercury that can contaminate ground water of local areas of paper mill industry. Studies on mercury in fish showed generally low levels of contamination resulting from low bioaccumulation of Hg in the mostly short food chains. Paper mill worker affected from the air and dust of mercury, and also damage their skin and nails. Due to, mercurous air around the paper mill industry asthma and respiratory diseases observed in the peoples.
