| The copper sensitivity of two species of snails in Shatt Al – Arab estuary ( Lymnae aurticularia ( Linneus ) and Theodoxus jordani ( Sowerby ) ) were evaluated . The snails were subjected to different concentrations of copper for 24 and 48 hours . The experimental tests were carried out in laboratory using renewal toxicity system . The medium lethal concentration ( LC50 ) values indicated that the snail L . aurticularia was more sensitive to copper than T . jordani . | ||
