“…We also propose a global hazard evaluation that compiles all calculated LOE indices within a single one that is also finally assigned to a hazard class. This approach was successfully applied to the assessment of the health status in multicontaminated environments such as harbors and urbanized and/or industrial areas (e.g., Piva et al 2011;Benedetti et al 2012;Bebianno et al 2015). These studies generally focused on sediment hazard assessment.…”

Quality assessment of environments under high anthropogenic pressures such as the Seine Basin, subjected to complex and chronic inputs, can only be based on combined chemical and biological analyses. The present study integrates and summarizes a multidisciplinary dataset acquired throughout a 1-year monitoring survey conducted at three workshop sites along the Seine River (PIREN-Seine program), upstream and downstream of the Paris conurbation, during four seasonal campaigns using a weight-of-evidence approach. Sediment and water column chemical analyses, bioaccumulation levels and biomarker responses in caged gammarids, and laboratory (eco)toxicity bioassays were integrated into four lines of evidence (LOEs). Results from each LOE clearly reflected an anthropogenic gradient, with contamination levels and biological effects increasing from upstream to downstream of Paris, in good agreement with the variations in the structure and composition of bacterial communities from the water column. Based on annual average data, the global hazard was summarized as "moderate" at the upstream station and as "major" at the two downstream ones. Seasonal variability was also highlighted; the winter campaign was least impacted. The model was notably improved using previously established reference and threshold values from national-scale studies. It undoubtedly represents a powerful practical tool to facilitate the decision-making processes of environment managers within the framework of an environmental risk assessment strategy.

“…Therefore, the significant risk increases of metal contamination in surface sediments should be taken into account for the park administration to reduce further environmental hazard risks. Even in a Portugal harbor with extensive shipping activities, Bebianno et al [28] found that metals, especially Pb, led to 100% of contribution to the specific hazard quotients at moderate to major risks in surface sediment using the same model of this study [15]. They also identified the hazard risk of urban contribution to surface sediments in the harbor from upstream [28].…”

“…Nevertheless, the mean total PAHs concentration in the impacted samples exceeded the TEL and ERL, suggesting potential toxicological effects of chronic exposure. Under acute exposure, sublethal endpoints such as antioxidant enzymatic activities are considered as relevant indicators of PAHs pollution in marine organisms (Orbea et al 2002;De Luca-Abbott et al 2005;Sureda et al 2011;Bebianno et al 2015). These 'non-specific' biomarkers have frequently been used for environmental monitoring assessments sometimes with results that are difficult to interpret (Vlahogianni et al, 2007;Valavanidis et al 2006;Brooks et al 2013;Nahrgang et al 2013).…”

Recent offshore petroleum exploration has increased the risks of oil spills worldwide. We investigated biomarker responses to diesel oil exposure in two tropical and subtropical species, the clam Anomalocardia flexuosa and the polychaete Laeonereis culveri. Animals were exposed to oil-spiked sediment at two different concentrations (0.5 L m -2 and 1.0 L m -2 ). Activities of antioxidant enzymes catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GPx); glutathione transferase (GST), and lipid peroxides (LPO) were assessed in bivalve digestive glands and polychaete whole-body homogenates at 36 h and 60 h of exposure.Significant variation in enzymatic antioxidant activity depended on the sampling time after exposure. No similar response patterns, either increases or decreases, were detected for the two target species, and biomarker responses were species-specific. L. culveri showed clearer patterns in its antioxidant response and should be prioritized over other species in biomonitoring studies involving oil exposure. Understanding the temporal variability of these biomarkers is a necessary action before implementing them as indicators measures in oil contamination biomonitoring programs. Our results provide a better understanding of biomarker responses in subtropical species, evidencing their potential use as sentinels of oil contamination.
