Kaladharan, P and Leelabhai, K S (2007) Effect of humic acids on mercury toxicity to marine algae. Fishery Technology, 44 (1). pp. 93-98.
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.
