large number of aquatic ecotoxicity studies have been conducted with
benzene. Following the approach in the EU RAR for benzene (2008) tests
conducted in flow-through systems with
analytical confirmation of the exposure concentration have been
preferentially selected as key studies because of the high volatility of
assessment toxicity screening criteria are that an acute EC50 or LC50
<0.1mg/L is considered to be T, and that an EC50 or LC50 <0.01mg/L
indicates that the substance is definitely T. Experimental acute and
chronic ecotoxicity data are available for benzene. The acute effect
concentrations are greater than the screening criteria and the chronic
values are greater than the toxicity criteria stipulated in Annex XIII.
Therefore, benzene is not considered to be T.
