FEEDING AND GROWTH RESPONSES TO COPPER, ZINC, MERCURY AND LEAD IN THE TERRESTRIAL GASTROPOD ARIONATER (LINNE)

Food consumption and growth variations related to several dosagesof heavy metals (Cu, Zn, Hg and Pb) in diet were studied inthe terrestrial slug Arion ater for 27 days of experimentaltreatment. The work reported here is part of a larger project to investigatethe histological effects of metal exposure in pulmonate gastropods. Graphics on food consumption and growth vs. time for each metal,and regression for each behaviour observed are presented. (Received 30 May 1985;
