Abstract

Oxygen capacity, oxygen and carbon dioxide contents of blood of control
O. mossambicus were 14.33, 4.06 and 8.01 vol. % respectively. Upon exposure
to sublethal and lethal concentrations of endosulfan, the oxygen content of
blood decreased, while the carbon dioxide content increased. Blood pH
decreased due to increase in its C02 content. Derangement in blood gas levels
under endosulfan toxicity signifies inability of the pigment to carry out its
normal respiratory functions. This calls for careful application of pesticides to
protect inland water life including fish.
