Quantitative changes in the digestive gland cells of the snail Helix aspersa after exposure to the fungicide copper oxychloride

Bioaccumulation of copper and toxic effects on feeding, growth, fecundity and development of pond snail Lymnaea luteola L.

“…Our results agree with studies carried out on the adult L. luteola Cu acute toxicity tests. For example, 96 h acute toxicity tests of Cu to adult snail L. luteola were conducted and the EC 50 values and 95% confidence limits calculated were 27 (23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35) g L −1 of Cu [13]. In another experiment, Mathur et al [22] determined the 96 h EC 50 value of 172 g L −1 of Cu for L. luteola in hard water (hardness: 315 mg L −1 as CaCO 3 ).…”

“…It has been reported that digestive gland may operate as a storage area of heavy metals [31]. The digestive gland showed bioaccumulation of Cu and there was a rise in copper concentration of this organ from 76.28 g g −1 (control) to 123 g g −1 (with exposure at 32 g L −1 of Cu) in L. luteola.…”

Temporal and Spatial Effects on Some Physiological Parameters of the Bivalve <i>Lithophaga lithophaga</i> (Linnaeus, 1758) from Coastal Regions of Alexandria, Egypt

“…[53] reported that the digestive gland appears as the center of accumulation of Cu, as Cu is strongly accumulated in the digestive gland and that digestive gland is the main site of Cu accumulation in mollusk. The present study did not agree with that observation as gills represented the main site of Cu accumulation in Lithophaga lithophaga, whereas, [54] reported that the digestive gland of Mytilus edulis is the preferential organ for the accumulation of heavy metals.…”

Light and Scanning-Electron Microscopic Study of Eisenia fetida Coelomocytes after Copper Oxychloride Exposure

“…Copper oxychloride is a broad-spectrum fungicide applied to the foliage of a wide variety of fruits and vegetables [12]. It is sprayed directly on crops and in long term, can result in significant amount of copper (Cu) accumulation in soil.…”
