Summary: Plastic debris can serve as a significant source of hazardous chemicals in the ocean, and its role in the environment is still not fully understood. A comprehensive field study comparing highly contaminated and non-contaminated islands revealed that stranded plastics play a crucial role in the bioaccumulation of plastic additives in marine debris-contaminated areas. This study provides the first field evidence that plastic debris movement in the ocean contributes to the dispersal of plastic additives to pristine waters.

Summary: The study evaluates the impact of seawater physico-chemical characteristics on the relationship between metal concentrations measured by passive samplers and discrete water samples. The results indicate that the variability in metal content in waters, rather than environmental conditions, affects the ratios. These ratios were not significantly affected by various environmental factors, providing confidence in the techniques used. This simplicity could aid in implementing passive sampling techniques like DGTs in monitoring networks within regulatory frameworks like the EU Water Framework Directive.

Summary: This study focused on the pollution of surface water by polar pesticides in river catchments, developing a novel strategy using passive sampling coupled to suspect screening and multivariate analysis. A total of 128 different classes of pesticides were identified using high-resolution liquid chromatography-quadrupole-time-of-flight mass spectrometry. Statistical analysis revealed pesticide sources and fate, prioritizing 61 pesticides for risk assessment and designing a seasonal monitoring program. Incorporating passive sampling coupled to suspect screening into regulatory monitoring could better inform water quality management practices and reduce operational costs.

Summary: This study investigates the relationships among different chemical forms of Ni, Cd, and Pb in coastal and transitional waters across a broad geographical scale. The concentrations of metals vary greatly among sampling sites and methodologies, mainly due to natural water fluctuations. The labile fractions of Cd and Pb in spot samples are highly correlated, with Pb's labile fraction significantly lower than Cd's.

Summary: This study presents a novel and rapid approach using multi-residue targeted analysis and machine learning-assisted in silico suspect screening to characterise the occurrence of contaminants of emerging concern (CECs) in river water. By deploying passive samplers configured with HLB sorbents in the tidal River Thames catchment, differences in the presence of various compounds between summer and winter campaigns were observed. The innovation in this approach lies in the convenience of combining passive sampling with machine learning-assisted chemical analysis for rapid and time-integrated monitoring of CECs in the catchment.
