The 48 h-EC50 exceeded 0.62 mg/l, being the average measured concentration in a WAF prepared at a loading rate of 100 mg/l.
The acute toxicity test with Daphnia
magna was performed according to OECD guideline No. 202 under GLP
compliance. The result showed the test substance did not induce acute
immobilisation of Daphnia magna at 0.62 mg/l, being the average measured
concentration in a WAF prepared at a loading rate of 100 mg/l after 48
hours of exposure (NOEC). The 48 h-EC50 exceeded 0.62 mg/l, being the
average measured concentration in a WAF prepared at a loading rate of
Alkylated naphthalene, EC Number 700-826-8, is a close structural analog
of the Alkylnaphthalene being assessed in this dossier. The substances
have similar chemical and physical properites and therefore the aquatic
invertebrate toxicity testing for Alkylated naphthalene, EC Number
700-826-8, can be used as read-across to the alkylnaphthalene in this
A 48 -hour daphnia toxicity study was conducted by another company and
it was discovered as being available for read-across. The study was
identified during the Inquiry process. Measured concentrations were not
reported but the EC50 was reported to be greater than the loading rate
of 5029 mg/L. These data confirm the low toxicity of alkylnapthalene to
aquatic invertebrates was demonstrated with the analog Alkylated
