Abstract

Abstract: Probabilistic environmental quality criteria for Naphthalene (Nap), Phenanthrene (Phe), Fluoranthene (Flu), Pyrene (Pyr), Triclosan (TCS), Tributyltin (TBT), Chlorpyrifos (CPY), Diuron (DUR), γ-Hexaclorocyclohexane (γ-HCH), Bisphenol A (BPA) and 4-Nonylphenol (4-NP) were derived from acute toxicity data using saltwater species representative of marine ecosystems, including algae, mollusks, crustaceans, echinoderms and chordates. Preferably, data concerns sublethal endpoints and early life stages from bioassays conducted in our laboratory, but the data set was completed with a broad literature survey. The Water Quality Criteria (WQC) obtained for TBT (7.1·10 −3 μg L −1 ) and CPY (6.6· 10 −3 μg L −1 ) were orders of magnitude lower than those obtained for PAHs (ranging from 3.75 to 45.2 μg L −1 ), BPA (27.7 μg L −1 ), TCS (8.66 μg L −1 ) and 4-NP (1.52 μg L −1 ). Critical values for DUR and HCH were 0.1 and 0.057 μg L −1 respectively. Within this context, non-selective toxicants could be quantitatively defined as those showing a maximum variability in toxicity thresholds (TT) of 3 orders of magnitude across the whole range of marine diversity, and a cumulative distribution of the TT fitting to a single log-logistic curve, while for selective toxicants variability was consistently found to span 5 orders of magnitude and the TT distribution showed a bimodal pattern. For the latter, protective WQC must be derived taking into account the SSD of the sensitive taxa only.

Under protection of current criteria and lack of data for several pollutants. Criteria for PAHs, biocides, Bisphenol A and 4-Nonylphenol in seawater. Abstract : Acute Water Quality Criteria for marine waters are derived on the basis of Species Sensitivity Distribution curves using early life stages and sensitive endpoints.
