This document specifies a method for determining the toxicity of environmental samples on growth, fertility and reproduction of Caenorhabditis elegans<\/i>. The method applies to contaminated whole freshwater sediment (maximum salinity 5 g\/l), soil and waste, as well as to pore water, elutriates and aqueous extracts that were obtained from contaminated sediment, soil and waste.<\/p>\n Water and soil quality.
