标准范围

本文件通过解决对海洋生物的潜在生态毒理学不利影响，规定了测试方法和评估标准。对海洋物种的不利影响可能是由塑料材料的可溶性降解产物引起的，例如中间体或剩余残留物，这些塑料材料用于海洋应用产品（例如养鱼用网、推车绳、浮标、浮标和其他非捕鱼应用），并且用于不同的海洋区域，例如近岸、近岸或远洋区域。生态毒性测试计划涵盖四个营养级的海洋生物，初级生产者、初级和次级消费者以及分解者:—？对海藻的毒性，—？对海洋无脊椎动物的毒性，—？对海洋鱼类的毒性，—？对海洋微生物的毒性。本文件不适用于评估任何尺寸的固体材料引起的不良影响。

This document specifies test methods and evaluation criteria by addressing potential ecotoxicological adverse effects on marine organisms. Adverse effects on marine species can be caused by soluble degradation products of plastic materials such as intermediates or remaining residues resulting from the biodegradation of plastic materials that are used in products for marine applications (e.g. nets for fish farming, dolly ropes, floats, buoys and other non-fishing applications) and which are used in different marine zones, e.g. eulittoral, sublittoral or pelagic zones.

The ecotoxicity testing scheme covers marine organisms from four trophic levels, primary producer, primary and secondary consumers and decomposer:

—    toxicity to marine algae,

—    toxicity to marine invertebrates,

—    toxicity to marine fish,

—    toxicity to marine microorganisms.

This document is not suitable for the assessment of adverse effects caused by solid materials of any size.
