Studies on calcium, magnesium and sulphate in the Mandovi and Zuari river system (Goa)
Distribution of calcium, magnesium and sulphate have been examined in the tide-dominated Mandovi and Zuari river systems. Calcium and magnesium appear to take some part in the bio-geochemical cycles of the rivers and behave ...
A toxin from Holothuria leucospilota (Brandt)
(Oxford and IBH, New Delhi, 1991)
Holothurians are marine echinoderms. Despite their limited mobility and absence of a protective hard shell, they are seldom preyed upon. Thus, one would expect them to have some type of chemical defence mechanism in the ...

An average of 55,000 t of pesticides (including or organochlorine compounds) are used every year in India for agricultural purposes. The cumulative effects of these pesticides on the coastal environment can be expected to ...
Some aspects of the nitrogen cycling in the Arabian Sea

Organochlorine residues in zooplankton off the Saurashtra coast, India
Zooplankton samples were collected by neuston net (250 mu m) at the sea surface for about 40 min
DDT residues in sediments from the Bay of Bengal
DDT is one of the organochlorine compounds characterised by its stability for long periods in the environment leading to marked changes in the aquatic ecosystem. This work aims to assess the prevailing levels of DDT and ...
