title: The efficiency of various solvents in the extraction of chemical mutagens from living tissues: a comparative study.
abstract: The aim of this study is to find out the best solvent to be used in extraction of chemical pollutants from living organisms. Ethanol, benzene, chloroform, pentane, 1,4-dioxan, acetone, cyclohexane and ether were used in extraction of shrimp and clam samples collected from a Fahaheel site. The tissue extracts were tested for their mutagenic activity using E. coli and Salmonella on tester strains. The results revealed that ethanol was more efficient than other solvent in extraction of chemical mutagens concentrated in clams and shrimps.
