It is known for a long time that calcified tissues secreted by aquatic or terrestrial invertebrates – such as mollusc shells – have the ability to concentrate large amounts of pollutants, in particular heavy metals. In the present paper, we have found an extremely rapid and easy procedure to qualitatively detect the putative presence of heavy metals in shells, without having to use   Assessment of heavy metal and PAH exposure in largemouth bass (Micropterus salmoides) in the Reedy River watershed, South Carolina, USA: A multi-season assessment of metallothionein and bile fluorescence.

Effects of heavy metal pollutants on Littorina Littorea (L.) and its marine trematodes by Marcus Antony Cross Download PDF EPUB FB2

Inductively coupled plasma atomic emission spectrophotometry (ICP-AES) was used to determine heavy metal concentrations in the shells and soft tissues of the periwinkle Littorina littorea, collected at seven sites along the Scheldt estuary.

Along the WS metal and MT levels in periwinkles reflected the known downstream decreasing pollution :// For example, concentrations of Fe, Mn, Pb and Zn in periwinkles Littorina littorea (as μg g −1 dry soft-body weight) decrease with increasing soft-body weight while heavy metal contents in individual periwinkles (μg individual −1) always increase significantly according to size (Boyden, ).

Ecotoxicology can be defined as the study of the contamination of ecosystems (i.e., input, concentration, distribution, and speciation of the pollutant in the ecosystem) by natural and artificial pollutants, their mechanisms of accumulation (i.e., uptake, elimination, and detoxification) and their effects on living organisms (see Ramade ; Ravera ; Bouquegneau et al.
