Start year 2005 End year 2007 Funding (€) € NA Website NA Summary This study was made by ICRAM with the aim to investigate the possibility that levels of environmental pollutants such as heavy metals, butyltins, polycyclic aromatic hydrocarbons, polychlorinated dibenzodioxins, dibenzofurans and biphenyls, present into the fleshes of clams Tapes philippinarum gathered in contaminated areas of the Lagoon of Venice could be reduced by transplanting them into rearing areas. Clams were collected in May 2005 into the industrial area of Porto Marghera and were transplanted in two rearing areas of the Southern Lagoon. Sediments were also collected at the gathering and seeding sites of molluscs; subsequently both clam and sediment samples were gathered after 30, 60, 180 and 365 days from transplanting. Evaluating ways and time of contaminant depletions, physiological and biochemical measurements were made on animals (condition index, gross biochemical composition, maturation scales of gonads). Finally physic and chemical characteristics of sediments were monitored. As a result it could be possible to have more indications about changing trends of contaminations in clams due to environmental and endogenous variations. Although some pollutants didn't show a clear trend of depletion due to transplanting, concentrations resulted in this study were lower when compared with other geographical areas (Fukuyama et al., 2000; Abad et al., 2003; Byrne, & O'Halloran, 2004; Sayaka et al., 2004). It was very significant that some contaminants did accumulate after transplanting from the industrial zone of Porto Marghera to two rearing areas of Southern Lagoon of Venice. Useful information was obtained from this research to rationalize the clam harvesting the Lagoon of Venice and to define the quality of marketed and consumed products.
The aim of this research was: (1) To investigate the possibility that levels of environmental pollutants such as heavy metals, butyltins, polycyclic aromatic hydrocarbons, polychlorinated dibenzodioxins, dibenzofurans and biphenyls, present into the fleshes of clams Tapes philippinarum gathered in contaminated areas of the Lagoon of Venice could be reduced by transplanting them into rearing areas; (2) Evaluating ways and time of contaminant depletions; physiological and biochemical measurements were made on animals (condition index, gross biochemical composition, maturation scales of gonads); (3) To have more indications about changing trends of contaminations in clams due to environmental and endogenous conditions; (4) Obtained information to rationalize the clam harvesting in the Lagoon of Venice and to define the quality of marketed and consumed products.
