Applicant's summary and conclusion
- Validity criteria fulfilled:
- not specified
- Conclusions:
- The addition of activated charcoal did not cause any adverse affect or lethality to fish up to the tested concentration of 100 mg/L even in the presence of cyanophos residues in the water.
- Executive summary:
In (Romeh, Ashour et al. 2009)the effects of activated charcoal addition in water contaminated with cyanophos were investigated on Clarias Iazera fish. Four groups of animals were exposed to water with different additives as following: Group 1: 9.33 mg/L cyanophos; Group 2: 9.33 mg/L cyanophos + activated charcoal 100 mg/L; Group 3: 9.33 mg/L cyanophos + rice husk ash 100 mg/L; Group 4: Control group. The addition of activated charcoal to water contaminated with cyanophos reduced clearly the levels of residues in water and in fish gills, liver and muscles. In parallel, the addition of activated charcoal did not cause any adverse affect or lethality to fish up to the tested concentration of 100 mg/L even in the presence of cyanophos residues in the water.
