Half-lives and bioconcentration of lindane (γ-HCH) in different fish species and relationship with their lipid content

In this investigation it is demonstrated that the half-lives of the insecticide lindane (γ-HCH) in mussels and different fish species are dependent on their lipid content. It is found that the bioconcentration factors on a wet weight basis (BCF w) of γ-HCH in different aquatic organisms such as muss...

Description
Summary:In this investigation it is demonstrated that the half-lives of the insecticide lindane (γ-HCH) in mussels and different fish species are dependent on their lipid content. It is found that the bioconcentration factors on a wet weight basis (BCF w) of γ-HCH in different aquatic organisms such as mussels, Daphnia, and fishes range from 43 to 4240. It is further demonstrated that the bioconcentration factors on a wet weight basis are positively correlated with the lipid content (%). The mean bioconcentration factor on a lipid basis (BCF L) of γ-HCH is 11,000. This BCF L value is in satisfactory agreement with the log K ow value of lindane (4.10).
