Trends in the concentrations of Cd, Cu, Hg, Ni, Pb and Zn in the estuary of the River Thames between 1980 to 1997 were examined using linear regression methods to determine whether stated reductions in metal discharges from all sources to the estuary have had an effect on water quality. Concentrations of all metals, except Pb, showed exponential declines. Lower dilution capacities triggered by drought events post 1989 and continued use of leaded gasoline, reversed initial declines observed in… CONTINUE READING
