Therefore, pollution intensity can be an important fostering factor in HM transfer in terrestrial ecosystems. First Online: 15 June R Google Scholar. Palaeontol Electron. Firstly we aimed to find which of the shell main conchological features, shell height SH or shell weight SWallows a more accurate estimation of shell volume.

Similarly, Zn, Cd, and Pb biomagnified in H. The digestion solutions HNO 3 0. Flatter shells facilitate movement on substrates with foliated structures e. HM pollution of the soil is often less visible and direct than other types of land pollution e. Environ Pollut. Skip to main content Skip to sections. Overall, terrestrial gastropods have the potential to be used in environmental monitoring as model invertebrate for Cu, Zn, Cd, and Pb accumulation in terrestrial ecosystems [ 28 ].
No decimal places representin large uncertainties are used. When values vary, with equal probability on both si es, so far as our present knowledge goes, as in. Lead: PbCl2, PbBr2, PbI2, Pb(OH)2, PbSO4, and PbS (and others) would be insoluble.
