This document specifies a method for determining the toxicity of environmentalsamples on growth, fertility and reproduction of Caenorhabditis elegans. The method appliesto contaminated whole fresh water sediment (maximum salinity 5 ‰), soil and waste, as wellas to pore water, elutriates and aqueous extracts that were obtained from contaminatedsediment, soil and waste.

This document specifies a method for the determination of the dissolved fraction of selected active pharmaceutical ingredients and transformation products, as well as other organic substances (see Table 1 of the document) in drinking water, ground water, surface water and treated waste water.The lower application range of this method can vary depending on the sensitivity of the equipment used and the matrix of the sample. For most compounds to which this document applies, the range is = 0,025 µg/l for drinking water, ground water and surface water, and = 0,050 µg/l for treated waste water.The method can be used to determine further organic substances or in other types of water (e.g. process water) provided that accuracy has been tested and verified for each case, and that storage conditions of both samples and reference solutions have been validated.
