Abstract The present study was undertaken with the databank of dissolved Pb and pH of the aquatic system in the East Kolkata Wetlands, an internationally unique Ramsar Site of Eastern India during a period of twenty years (2000-2019). Our study site is receiving huge amounts of domestic and industrial wastewater from surrounding areas of highly populated metropolitan city of Kolkata. The data on pH exhibits a decreasing trend with the passage of time, which may be attributed to the phenomenon of acidification in which CO2 dissolves with the water and shifts the pH to a lower value. This may result in the dissolution of accumulated Pb in the sediment and transfer the same to the overlying aquatic phase. The increasing trend of dissolved Pb confirms the hypothesis. The significant negative correlation between pH and dissolved Pb (r= -0.7763; p≤0.01) supports the view of the regulatory effect of pH on the dissolved Pb level in the aquatic systems of East Kolkata Wetland.

The Past

Burdwan, in West Bengal, a densely-populated and relatively prosperous area of Eastern India, was chosen for the first of a series of detailed analyses of the socio-economic effects of the so-called ‘green revolution’ of the past decade. The new technology has put a premium on land. Expenditure on fertilizers, tractors and tubewells has ‘increased dramatically’. Medium to large farmers’ efficiency and incomes have improved but benefits have been distributed less than equitably.
