Bioassay tests were conducted with wastewater effluents from a textile mili and a detergent packing plant using the hermit crab. Clibinarius africanus. (Aurivillus) as experimental animal. LC50 values were evaluated using static testing procedures for 24, 48 and 96 hour. For the textile effluent, means of 79.0, 50.24 and 51.81 percentage effluent by volume were obtained in respect of crabs in the “medium” weight range (0.3 – 0.7grams) for the test periods. For the “detergent wash”, 95.16, 85.00 and 82.33 percentage effluent by volume represented means of values obtained for “small” size crabs (weight range 0.08–0.24 grams) and 96.0, and 81.50 percentage effluent by volume for ‘medium’ size crabs for 24, 48 and 96 hour respectively. Spearman’s Rank... |
