Acetylcholinesterase activities in marine snail (Cronia contracta) as a biomarker of neurotoxic contaminants along the Goa coast, West coast of India
Gaitonde, D.; Sarkar, A.; Kaisary, S.; DeSilva, C.; Dias, C.F.M.; Rao, P.V.S.S.D.P.; Ray, D.; Nagarajan, R.; DeSousa, S.N.; Sarkar, S.; Patill, D. (Springer, 2006)The measurement of acetylcholinesterase (AChE) activity is used worldwide as a biomarker of environmental contamination due to neurotoxic substances. In the present study the AChE activities was measured in marine snails ... -
Chemistry of the sea-surface microlayer. 3. Studies on the nutrient chemistry of the northern Arabian Sea
Singbal, S.Y.S.; Narvekar, P.V.; Nagarajan, R. (Oxford and IBH, New Delhi, 1992)Nutrients showed enrichment in the surface microlayer compared to those in sub-surface water and there was a decreasing trend in the enrichment factor from nearshore to offshore in Northern Arabian Sea. The nutrient ... -
