✦ Synopsis
Some typical and more frequent freshwater invertebrates of running waters were studied to examine the influence of styrene, xylene and benzene on their mortality. Snails Amphimeluniu holundri FER. and Lymnueu srugnulis L. and crustacenas Asellus uquuticus L. and Gummurus fossurum KOCH., were used in the semi-static test. Compounds were added in volume concentrations of 0.005 to 0.4% v/v. For all concentrations LCB was calculated by probit method, which demonstrated that mortality depends much more on increased concentrations (depending on the initial concentration) than on the length of exposure. Styrene was the most toxic, followed by xylene and then benzene. The species G. fossurum showed marked sensitivity, followed by A. uquuticus, and the species A. hukundri and L. srugnalis showed less sensi tivity .
