Abstract:Superoxide dismutase (SOD), catalase (CAT), guguangantai peroxide enzyme (GSH-PX), guguangantai-S-transferase (GST), and cholinesterase (CHE) were measured in the innards of Bellamya purificata in different plots of the Jing-Hang canal to study the changes of these enzyme parameters under environmental variation. The correlation between these enzyme activities and heavy metal content in substrate sludge was analyzed. The results indicate that SOD, CAT, GSH-PX, and GST in Bellamya purificata are sensitive parameters as biomarkers of exposure to pollutants. The result is accordant with result of using water chemical parameters assessment method.Within 30 days of exposure, SOD is activated, but CAT, GSH-PX and GST are inhibited in all polluted plots. The change of CHE activity is complex. It was correlated between enzyme activity and heavy metal content in substrate sludge.
