An innovative approach for the simultaneous quantitative screening of organic plastic additives in complex matrices in marine coastal areas

Résumé

Aiming the simultaneous determination of widely used organic plastic additives in complex marine matrices, this work proposes a fast and "green" analytical protocol based on quick, easy, cheap, effective, rugged, and safe (QuEChERS) technology. The validation of this innovative method on real matrices (i.e., sediments, mussel, fish, and Posidonia oceanica) indicated a general good performance in all of them for phthalate esters (PAEs), with low blank levels and average method recoveries varying from 54 ± 11 to 71 ± 12%. The best method performance for organophosphate ester (OPE) flame retardants and plasticizers was in biotic matrices (recoveries 52 ± 31 to 86 ± 38%). This application represents an innovative QuEChERS sequence of two disper-sive solid-phase extraction (SPE) steps enabling this approach for the determination of important families of organic plastic additives in the marine environment. Indeed, our method allowed the fast screening and simultaneous determination of OPE and PAEs in various sites and matrices subject to different anthropogenic pressure in coastal NW Mediterranean Sea for the first time. ∑ 7 PAE and ∑ 9 OPE concentrations of 19-83 and 27-116 ng g −1 dw (fish), of 80-714 and 42-71 ng g −1 dw (mussels), of 192-908 and 47-151 ng g −1 dw (Posidonia oceanica), and of 11-328 and 4-10 ng g −1 dw (sediment) were measured, respectively. Our approach was sensible enough as to detect differences in the (bio)accumulation patterns of the target compounds in various species and/or sites. This application opens new perspectives for environmentally friendly marine environment monitoring and screening campaigns for organic plastic additives.
