Copper ecological risk assessment using DGT technique and PNEC: A case study in the Brazilian coast

• Coupling between DGT technique and a site-specific PNEC derivation. This novel tool could be applied in monitoring programs. Labile copper input is directly associated with the application of antifouling paints. Cu labile concentrations shipyard areas represent an alarming ecological risk. A 0.16 ?g.L ?1 suggested to protect Brazilian estuarine areas. Estuarine systems are vulnerable metals stress, such as (Cu). Thus, development applicable tools improve routine programs increasingly necessary. In present work comprehensive Ecological Risk Assessment (ERA) was implemented by coupling Measured Environmental Concentration (MEC), based on (DGT) total dissolved concentration. Additionally, toxicity data related Predicted No Effect (PNEC) were used. As case study, selected coast, previously reported release The results indicated increase during locations where more vessels maintenance found, concentration Cu-DGT exceeded value (0.16 ) represented important part fraction (>93 %). MEC/PNEC quotients, showed that high it highlighted need for environmental assessments manage complex ecosystems set legislation. Consequently, derivation easily alternative classical ERAs.
