- Plastic-contaminant interactions in the semi-enclosed Black Sea basin. Aytan, Ulgen Pasli, Serap Minaz, Mert Canli, Oltan Guzel, Baris Plastics Water Pollutants, Chemical Black Sea Environmental Monitoring Gas Chromatography-Mass Spectrometry Persistent Organic Pollutants Spectroscopy, Fourier Transform Infrared This study quantified the plastic additives (PADs) and persistent organic pollutants (POPs) on commonly used polymer types exposed for one year under environmental conditions in the Black Sea. Chemical analyses were performed using gas chromatography - tandem mass spectrometry (GC-MSMS) to identify and quantify organic pollutants, while polymer characterization was conducted using Fourier-transform infrared spectroscopy IR/Raman spectroscopy. Across all samples, PAD concentrations exceeded POP levels, indicating strong retention of manufacturing-derived chemicals. Contaminant loading varied markedly among polymers, reflecting differences in polymer chemistry, product function, and surface morphology. High-density polyethylene (HDPE) and polypropylene (PP) items, particularly protective gloves and Personal Protection Equipment (PPE) materials, exhibited high burdens of plasticizers and phenolic additives. In contrast, polyacrylonitrile (PAN) and nylon (PA) showed significant sorption of polycyclic aromatic hydrocarbons (PAHs), pesticides, and highly chlorinated polychlorinated biphenyls (PCBs), suggesting that textiles and fishing nets act as effective reservoirs for hydrophobic contaminants. These results demonstrate that plastics contribute disproportionately to the transport and persistence of hazardous chemicals in the semi-enclosed Black Sea system, where limited water exchange enhances long-term accumulation risks. Overall, the findings highlight the need to address plastics not only as visual litter but also as mobile chemical carriers, and to consider chemical load as an important component of regional monitoring and policy frameworks, with potential implications for marine ecosystem and human health protection.
