The 96hr-acute toxicity of Arsenic acid to Oncorhynchus mykiss was studied. Fishes were exposed to control, and test chemical at measured concentrations of 0 (control), 13, 24, 39, 65 and 110 mg a.i/L. Mortality and biological and physical effects were observed. The 96hr- LC50 was 28 mg/L, based on the measured concentrations. This study is classified as acceptable and satisfies with the guidelines requirements for an acute toxicity study with freshwater invertebrates.
Other data on Fish toxicity are
The 96hr-acute toxicity of Arsenic
acid toOncorhynchus mykissalevins and juveniles was studied.
Fishes were exposed to control and at a series of 6 to 10 test solution
concentrations. Mortality and abnormal behavioural responses were
observed. The 96hr- LC50 for alevins and juveniles were >360
and 67.5 mg/L respectively, based on the nominal concentrations. This
study is classified as acceptable and satisfies with the guidelines
requirements for an acute toxicity study with freshwater invertebrates.
Eisler reviewed the available data in
1997. The presented acute toxicity data of As5+on fish are
Goldfish Carassius auratus:
- LC50(7 days) = 24.6 to
- 15 % behavioural impairment in 24h;
30 % impairment in 48 h : 0.1 mg/l
LC50 (96h ) = 25.6 mg/L
