ABSTRACT:The depuration of 8 heavy metals (Zn, Pb, Ni, Mn, Cu, Cr, Co and Cd), total petroleum hydrocarbons and pathogenic bacteria of Paphia undulata was tested and the survival of depurated clams was evaluated. Investigated samples were collected from Ismailia, Egypt. The initial metal concentrations were significantly higher in the whole soft tissues than in water and sediment except for Mn. After 24 h depuration, Zn, Pb, Ni, Mn, Cu, Cr and Cd were significantly reduced to 44, 23, 25, 17, 61, 41, and 75%, respectively. After three days of depuration the reduction was significant only for Cu, Cr, Co and Cd (27, 15, 23 and 52%, respectively). The total petroleum hydrocarbons were reduced significantly to 72% after three days of depuration, while after 24 h they were reduced to 90% compared to their initial concentrations. Four pathogenic bacteria were identified in the soft tissues of P. undulata (Vibrio sp., Shigella sp., Escherichia coli and Salmonella sp.). After one-day depuration the results evidenced the mean microbial reduction to 75, 31, 68, and 36%, respectively, compared to their initial counts. After three days of depuration the counts of Vibrio sp. and Salmonella sp. were reduced to 3% and 8%, respectively, while Escherichia coli was not detected on the third day. Shigella sp. was increased by 22% compared to the first day of depuration. The viability and mortality were not influenced by the depurative treatment.

“…Many contaminants, such as dichlorodiphenyltrichloroethane, lindane, mercury, and cadmium, as well as PAHs and PCBs, have been detected in the Seine Estuary [12]. Because environmental contaminants are too numerous and chemical analysis is expensive, it is an unachievable goal to monitor all the compounds that are present in continental or marine waters.…”

Abstract-Zebra mussel (Dreissena polymorpha) is an invasive species that has proliferated in European and North American rivers and lakes during the last century. In this study, D. polymorpha has been used to provide information on contamination levels and biological effects in the Seine Estuary (France). The bivalves accumulated polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs) to a high degree with values reaching 800 ng/g dry weight for PCBs (sum of 20 congeners), and 1,000 ng/g dry weight of PAHs (sum of 14 compounds) in the whole body. These values are among the highest reported of PCBs and, to a lesser extent, of PAHs in other contaminated areas in the world. Toxic equivalent quantities of PCBs and PAHs detected in zebra mussels varied from 20 to 40 pg dioxin equivalents/g dry weight for PCBs and up to 120 ng benzo[a]pyrene equivalents/ g dry weight for PAHs, indicating a high potential risk for animals feeding on them. Biological impacts, such as altered condition index, decreased lysosomal stability, and high levels of multixenobiotic resistance (MXR) proteins also were detected in mussels living downstream of Rouen, the main city of the Seine Estuary. Taken together, these results indicate that the Seine Estuary is a heavily polluted area with the potential to cause deleterious health effects in some endogenous living organisms. This study also shows that chemical and biological measurements bring different but complementary results that can help diagnose environmental health.

“…To this end, it is of less ethical concern and more practical to use invasive rather than native species. This explains why many invasive species such as mosquitofish (Mulvey et al 1995), common carp (Solé et al 2003) or zebra mussel Dreissena polymorpha (Chevreuili et al 1996) are among the most studied in aquatic toxicology and water pollution monitoring.…”
