Uses of antibiotics in human and animal health sectors may create problem to the non- target organisms in the ecosystem. This study is designed to characterize the toxicity of erythromycin (ER) and amoxicillin (AM) on fish and mosquitoes as single and binary mixture. Toxicity of antibiotics was measured by calculating %death of mosquitoes or fish in the tested sample related to the %death of control sample . Relative toxicity of the tested compounds were calculated by subdividing the calculated LC50 of each compound that of endosulfan values below 1 indicate high toxicity whereas values above 1 indicate less toxicity. Results showed that (ER) and (AM) have considerable toxicity on fish and mosquitoes . LC50 values on fish indicate that AM is more toxic than ER or EN (standard toxic substance ). The relative toxicity of (AM) is lower than( EN) indicating more toxicity . Toxicity on fish is in the following sequences AM > EN > ER. Calculated LT50 indicates that EN has the lowest value. Furthermore the toxicity to mosquitoes is in the following sequence ER > EN >AM indicating more toxicity of erythromycin on mosquitoes . Relative toxicity indicates that ER and EN, nearly, have similar values whereas AM has higher value indicating less toxicity. Calculated LT50 values indicate that EN has the lowest value in mosquito test . Whereas AM and ER have nearly close values. Statistical analysis indicate significant difference in the toxicity on fish and mosquitoes. Comparison of LC50 values of fish and mosquitoes indicate that mosquitoes is more sensitive than fish to the tested antibiotics. An interesting outcome of this study is that AM is more toxic than EN to fish and ER is more toxic than EN to mosquitoes . These results are unique in this field and the first time in Gaza to be achieved. It is highly recommended to established an antibiotics residue analysis test to avoid discharge of antibiotics waste to the ecosystem.
