Environmental occurrence of organophosphate esters and micro-plastics in sediments and benthic organisms from the Loire Estuary (France)
SETAC Europe 32nd Annual Meeting, COPENHAGUE, DANEMARK, 15-/05/2022 - 19/05/2022 Organophosphate ester (OPE) flame retardants and plasticizers and microplastics (MPs) are emerging threats to the marine environment, presenting multiple sources in the environment and being widely distributed in sea an...
