Effects of Tin on Enzyme Activity in Holothuria grisea (Echinodermata: Holothuroidea).

Abstract
This study evaluated the effect of tin exposure on enzyme activity in the sea cucumber (Holothuria grisea Selenka, 1867). After exposure to 0 (control), 0.04, 0.08, or 0.12 mg L-1 tin, we tested the activities of total cholinesterase in longitudinal muscles, acid phosphatase in gonads and the respiratory tree, as well as alkaline phosphatase in the intestines during a 96-h bioassay. Regression analyses showed that all enzyme activities declined with increasing tin concentrations, except for acid phosphatase in the respiratory tree, which were similarly, inhibited at all tin concentrations. These results indicate that H. grisea is a potential bioindicator for seascape habitat monitoring programs, as its biochemical markers show sensitivity to trace elements that can indicate a rise in pollution levels.
