Description Humic acids extracted from the sediment of Cochin inshore areas exhibited impairment of mercury
toxicity to marine algae maintained in Walne's medium under laboratory conditions. Cultures of
marine micro alga /50chrysis galbana contaminated with sublethal concentration of 10 ppb of inorganic
mercury and 10 ppm humic acids registered 18%, 21 % and 37% increase in oxygen production for
two, four and six hours incubation in light respectively, when compared to the controls. Similarly
the daily growth rate of seaweed Ulva lactuca registered 26% increase over the control when the
seaweed was maintained in medium containing 30 ppb Hg and 30 ppm humic acids.
