dc.description.abstractDaphnia magna was exposed to the concentration 1/4 , 1/2 and 2/3 LC50 and LC50 of 6 anionic detergents to determine the effect of these detergents on filtration and ingestion rates. Two dish washing liquid in terms of active ingredient as linear alkyl benzene sulfonate each 17% but one with DE ethanolamine (5%) and lauric acid ethanolamid (2%) as its component part, including washing machine powder, two kind washing powders and a shampoo, which the last four active ingredients content were 10%, 19%, 20 - 22%, 12% respectively exposed to the test organism. The experiments were performed with unicellular algae Chlorella vulgaris in a density of 10 mg/l as a feed to Daphnia magna. Relatively simple short term bioassay methods were developed to measure the filtration and ingestion (5 hours) rate. The effective concentration at which feeding and ingestion rates were reduced to 50% of those in controls (LC50) was calculated for six detergents. These values were 9.87, 4.37, 22.8, 33.17, 21.81, 35.26 mg/l for feeding rate and 9.75, 5.67, 19.9, 44.26, 23.94, 43.41 mg/l for ingestion rates respectively. The results indicated the liquid detergents exerted high reduction in feeding and ingestion rates and the one with the ingredients of DE-ethanolamine (5%) and lauric acid (2%) influenced higher in reduction of feeding and ingestion rate. The effect of washing powder were greater to the feeding behaviour in comparison with washing machine powder, the shampoo observed with many limited effect on filtration and ingestion rates.en_US
