Comparative studies carried out on bottom sediment and water of Adyar, Ennore and
lake Pulicat during 1984- 85 revealed the presence of mercury, zinc, lead, copper, chromium,
nickel and cadmium in the.first two estuaries while lake Pulicat remained reasonably free from
heavy metal pollution. in Ennore estuary, the concentration of metals in sediments were higher at
the upper reaches (head of the estuary) and decreased towards the estuarine mouth while in Adyar
estuary, higher concentrations were noted in the middle of the estuary. The observed results were
compared with the concentrations for the unpolluted sediments. The concentrations of metals In all
the sediments showed considerable seasonal variation. (Key words: Estuarine sediments, heavy
metals, seasonality)
