Quantitative Changes in the Effects of Anthropogenic Activities on Bivalve Mollusc Hepatopancreatic Cells


This study set out to quantify the alterations in the hepatopancreatic cells of the Batissa violaceae. Clams from Northern Samar’s Catubig River were used as a bioindicator of pollution. Hepatopancreas was combined from the clams that were returned to the river and submerged for 72 hours, the depurated laboratory control group, and the chronically exposed group for the quantitative tests. After being histologically processed, hepatopancreas samples were viewed under a Ken-a-vision microprojector microscope. Comparatively to site 1 during the high flow phase, the epithelial height of the hepatopancreas cells’ tubules was smaller during the low flow period. Additionally, the depurated control had a significantly higher mean number of tubules during the high flow phase than the untreated control. In general, quantitative alterations in hepatopancreatic cells after acute and long-term exposures could serve as a biomarker of contaminant exposure.
