Monitoring of Metal Contamination in the Eggs of Two Bird Species in India

Monitoring of Metal Contamination in the Eggs of Two Bird Species in India

The eggs of birds are extensively used as biological indicator of metal pollution because they come from a specific fragment of the population, formed in a specific period, have consistent composition, easily sampled and the removal of one egg from a nest has a minor effect on population parameter. Many workers [2-7] have advocated the use of eggs to monitor metal contamination in birds as the birds get rid of their body burden of metals through feathers and eggs.
