- Executive summary:
The study was conducted to determine toxicity of test chemical to soil macro-organism in accordance with ISO (1993b) methodology. The test was performed on 2 months oldEisenia foetida which were stored in commercial worm bedding with worm food. Test was performed for 16 days in polypropylene wide-mouth jars with loose fitting lids at a temperature of 20°C. Aeration was achieved by punching the lids of jar with holes to allow ventilation and oxygen supply.Ten adult earthworms were placed into 600 g(dry weight) of natural soil which were used as control or soil: sludge mixtures of different proportions i.e., 50; 25; 12.5; and 6.2% which previously hydrated to 25% water-holding capacity in 1000-ml polypropylene wide-mouth jars with loose fitting lids to minimize water evaporation and animal escape. The 16 days LOEC value was determined to be 50% for toxicity and 2 for Stimulant effect. E. foetida showed a biomass increase when exposed to the stabilized textile sludge.
