1 Scope

This document specifies the corresponding assessment requirements for the potential adverse ecotoxicological effects on marine organisms and describes ecotoxicological testing.

The testing methods. Soluble decomposition products of plastic materials can adversely affect marine species, for example, those used in marine applications (such as aquaculture).

Plastic materials used in different marine areas (such as nearshore, sub-nearshore or open ocean areas).

Ecotoxicity testing included marine organisms at four trophic levels. primary producers, primary consumers, secondary consumers, and decomposers.

--Toxicity to seaweed;

--Toxicity to marine invertebrates;

--Toxicity to marine fish;

--Toxicity to marine microorganisms.

This document is not applicable to assessing the adverse effects of solid materials of any size.
