Methods of digestion of fish samples for mercury determination by flameless atomic absorption spectrophotometry have been investigated. Digestion in Teflon bombs, Kjeldahl flasks, or borosilicate test tubes gives comparable precisions and mercury recoveries. Because of their cost and effect in limiting productivity, Teflon bombs were considered unnecessary for analysis of fish samples. Experiments with cooked and uncooked fish samples have confirmed that no appreciable loss of mercury occurs during baking 30 min at 170 degrees C.

Mercury is one of the most dangerous environmental pollutants, both in its elemental form and in chemical combination. When mercury is released into the environment it gets transformed into methyl mercury through microbial action. The methylation of mercury is a key step in the entrance of mercury into food chains. This methyl mercury is mercury in its most pernicious form.

Tannery waste is one of the most complex and putrescible organic industrial wastes causing huge amount of water pollution. Through the excessive organic load present in tannery wastes the oxygen content of the waters is depleted, which leads to the death of fish and other aquatic animals. In India, Tamil Nadu is one of the largest exporters of leather.
