4. Ecotoxicity Substance ID: 71–43–2<br />

______________________________________________________________________________<br />

Species: other: Cloeon dipterum (Ephemeroptera, Insecta)<br />

Exposure period: 48 hour(s)<br />

Unit: mg/l Analytical monitoring: no data<br />

EC50: = 34 –<br />

Method: other<br />

Year: 1983<br />

GLP: no data<br />

Test substance: other TS<br />

Result: In this study, the 48 h LD50 values of benzene for several<br />

aquatic macroinvertebrates from different taxonomical groups<br />

have been determined to obtain information on the relative<br />

susceptibility of macrobenthos to aquatic toxicants.<br />

Test condition: At least 5 larvae of Cloeon dipterum (mayfly) were exposed<br />

in closed vessels with Dutch Standard Water (Canton J.H. &<br />

Slooff W. Ecotoxic. Envir. Saf. 6, 113–128, 1982) to various<br />

concentrations of benzene for 48 h at 19–21 degree C.<br />

The animals (age not specified) were collected from the<br />

river Rhine.<br />

Test substance: purest grade commercially available (>98% pure).<br />

Reliability: (2) valid with restrictions<br />

Flag: Risk Assessment<br />
