data on the acute toxicity of benzene to algae, Daphnia and fish
are available. The lowest reported acute effect concentration is 5.3
mg/L for fish. This
value would not result in a classification for acute hazard

has been shown to be readily biodegradable and has a measured log kow of
2.13 indicating that it is not expected to be bioaccumulative.
10thMarch 2011 Commission Regulation (EC) No 1272/2008 [CLP
Regulations] was amended. The new criteria for environmental
classification state that if chronic data is available this should be
used to determine the chronic classification. Benzene has a complete
chronic data set. The lowest chronic effect is a 32 day NOEC of 0.8 mg/L
for the fish species, Pimephales promelas. Since benzene is
readily biodegradable, the self-classification as chronic
Category 3 classification is applied under the CLP Regulations.
