Microplastics are ubiquitous in the environment. Due to still rising global production, the emission of polymers into the environment and the abundance of microplastics have increased accordingly. The hydrophobic surfaces of the particles can sorb chem. pollutants, therefore providing a potential pathway to accumulation by organisms. In this study, important industrial additives of emerging environmental concern, such as hydrophobic aromatic amines, were studied in relation to their sorption behavior on high-d. polyethylene and low-d. polyethylene microplastics. Diphenylamine (log POW (logarithmic octanol-water partition coefficient) = 3.5) showed strong sorption, carbamazepine (log POW = 2.5) showed moderate sorption, and aniline (log POW = 0.9) showed no detectable sorption behavior. Importantly, the sorption capacity increased with increasing salinity, leading to strong implications for ocean systems, as an elevated uptake of pollutants. Moreover, our study demonstrates that the ecotoxicol. effects of diphenylamine on the growth of the seaweed Ulva (sea lettuce, Chlorophyta) were reduced in the presence of microplastics. As the plastic particles withdrew enough contaminants from solution, even toxic levels of diphenylamine (c = 10-4 M) became tolerable for the algae. However, the pollutants initially sorbed on the microplastics can be released again at a later point in the process, thus having delayed pollution potential.
