A protocol for lixiviation of micronized plastics for aquatic toxicity testing
Chemosphere, 2023 Plastics contain various types and amounts of additives that can leach into the water column when entering aquatic ecosystems. Some leached plastic additives are hazardous to marine biota at environmentally relevant concentrations. Disparate methodological approaches have been adopted for toxicity testing of plastic leachates, making comparison ...
