TL;DR: Evidence is provided of the relationship between chemical composition and toxicity of plastic/rubber leachates, which ranged from slightly to highly toxic to mussels and algae, highlighting the need for a better understanding of the overall impact of plastic-associated chemicals on aquatic ecosystems.

TL;DR: Cfree reduction through MP sorption was reflected in a corresponding reduction of lethality and bioaccumulation, with no difference observed between ingestible and non-ingestible MP, which indicates that only free dissolved PAHs are significantly bioavailable to copepods under co-exposure conditions with MP-sorbedPAHs.

TL;DR: It is emphasized that the shape and chemical profile of a microplastic can influence its bioavailability and toxicity, drawing attention to the importance of using environmentally relevant microplastics and chemically profiling plastics used in toxicity testing.

TL;DR: This study investigates the environmentally relevant photodegradation of common MPFs: polyester (PET), polyamide (PA) and polyacrylonitrile (PAN), their respective additive chemical profile, together with their potential for additive leaching.

TL;DR: A range of molecular degradation products were identified in seawater leachates after UV exposure, with increasing abundance over the duration of the experiment, and a variety of additive chemicals were shown to leach from the MFs into seawater.
