The lowest result is a 7 day NOEC of 0.96 mg/L for ethylbenzene.
Two chronic aquatic invertebrate ecotoxicity
studies are available, with ethylbenzene, m- and p-xylene as the test
substances. Niederlehner et al (1998) investigated the effects of
m-xylene and ethylbenzene on Ceriodaphnia dubia reproduction over
7 days. The LOEC of 1.7 mg/L from Niederlehner et al (1998) for chronic
toxicity of ethylbenzene to invertebrates was taken by Environment
Canada as the critical toxicity value for ethylbenzene toxicity to
aquatic species in the Draft Screening Assessment Report (Environment
Canada 2014). Bjornestad et al (2005) investigated the effects of
p-xylene on Daphnia magna reproduction over 21 days following
OECD 211. Both studies included analytical confirmation of the exposure
The three reported NOECs from studies are
similar, 0.96 mg/L (ethylbenzene) 1.17 mg/L (m-xylene) and 1.57 mg/L
(p-xylene). The lowest value will be taken forward.
