A Tyrrhenian coastal area in southern Italy was flooded on July 2006. This event caused the spread of mud, detritus and the spill of industrial wastes into the sea water. Surficial sediment samples were collected and analysed for polychlorinated biphenyls (PCBs), organochlorine pesticides (OCPs), and polychlorinated dibenzop- dioxins and –furans (PCDD/Fs) in order to evaluate current contamination status and risk assessment by means of Toxic Equivalency Factors (TEF). Data analysis showed that PCBs and OCPs levels were low and homogeneous in the three areas while PCDD/F fingerprint showed an heterogeneous distribution, suggesting for these molecules different sources of pollution.

Abstract
A Tyrrhenian coastal area in southern Italy was flooded on July 2006. This event caused the spread of mud, detritus and the spill of industrial wastes into the sea water. Surficial sediment samples were collected and analysed for polychlorinated biphenyls (PCBs), organochlorine pesticides (OCPs), and polychlorinated dibenzop- dioxins and –furans (PCDD/Fs) in order to evaluate current contamination status and risk assessment by means of Toxic Equivalency Factors (TEF). Data analysis showed that PCBs and OCPs levels were low and homogeneous in the three areas while PCDD/F fingerprint showed an heterogeneous distribution, suggesting for these molecules different sources of pollution.Pubblicazioni consigliate
