영문 초록

Short-term acute toxicity of synthetic detergent(LAS) to larvae of loach, Misgurnus angillicaudatus was examined by static bioassay. The larvae were exposed to 15 different concentration of synthetic detergent for 16, 48, 72, 96 and 120 hours in order to determine median lethal concentration(LC50). The 100% mortarlity of larvae was showed within 120, 96, 48 and 16 hours for 6, 18, 3O and 38 ppm, respectively. The median lethal concentration values of the larvae were 12.59 ppm for 48 hours, 4.00 ppm for 96 hours and 1.02 ppm for 120 hours. The permissible toxicant concentration of acute toxicity to larvae was 0.37~0.43 ppm, and application factor of the synthetec detergent was 0.093~0.108. The median lethal time(LT50) for different concentration also was determined. The LT50 of 0.2 ppm was found within 165.1 hours and 2 ppm was 108.2 hours, while the LT50 of 8 ppm. was 60.3 hours and that of 38 ppm was 23.5 hours.
