This study demonstrates the migration and potential harm of plastics- and rubber-derived chemicals in the environment. A novel biomonitoring platform using caged lumpfish eggs combined with gas chromatography tandem mass spectrometry analysis was used to detect the target chemicals. Monitoring in Trondheim harbor and off the coast of Trondelag in Norway revealed the accumulation of various chemicals in deployed eggs.
Plastics- and rubber-derived chemicals are given increasing focus due to their migration into the environment and potential for causing detrimental effects. The current study demonstrates the use of a novel biomonitoring platform using caged fertilized eggs of lumpfish (Cyclopterus lumpus) in combination with gas chromatography tandem mass spectrometry analysis of a selection of target chemicals extracted from the lumpfish eggs after deployment. A monitoring campaign in the Trondheim harbor and off the coast of Trondelag in Norway was executed using the described system. Here we found accumulation of UV stabilizers (benzophenone and benzothiazoles), plasticizers (n-butylbenzenesulfonamide), reagents, and polymer synthesis precursors (bisphenol A, acetophenone, phthalide, and phthalimide) in deployed eggs. Several of the compounds were detected in concentrations above previously quantified legacy contaminants in the same study areas.
