NOECrepro (23 d) 7.8 µg/L D. magna (based on read-across from pentadecan-1-ol)
A 23 days NOECrepro value of 7.8 µg/L has
been determined for the effects of pentadecan-1 -ol on cumulative number
of offsprings of the freshwater invertebrate D. magna. This is the lowest
reliable value available for this endpoint and has been selected as key.
study report is available with the closely related substance
pentadecanol branched (a single methyl branch group in the
2-position).This type of branched structure is termed 'essentially
linear' and the physicochemical, toxicological and ecotoxicological
properties and behaviour do not differ significantly between such
structures and their linear analogues. It is therefore possible to
read-across between the two substances. Additionally these
isomeric substances have an identical molecular weight. The difference
in composition is dependent on the manufacturing process which may
create linear alcohols or simple mono-branched structures. Direct
read-across from pentadecanol branched to pentadecanol (CAS 629-76-5) is
A reliable 21 d NOEC(reproduction) value
of 30.2 ug a.i./L has been determined for the effects of
pentadecanol branched on the number of reproductive young produced
per day of the freshwater cladoceran Daphnia magna. The water
solubility of pentadecanol branched has been estimated to be 0.07
mg/L. Therefore the NOEC is >limit of solubility (>LoS).
