to soil macroorganisms except arthropods
shows no effects up to the limit concentration in acute aquatic toxicity
tests. Furthermore, the substance shows no potential for accumulation in
soil due to its ready biodegradable properties, its LogPow value and is
not ionisable. Therefore,an impact
on terrestrial organisms is very unlikely and thus, studies on soil
organisms are not required.
there are two soil studies available with a fungicide formulation,
containing up to 35% pentanols. The results demonstrate that further
terrestrial studies with pentanols are not necessary.
In a 14-day
acute toxicity study with Eisenia fetida no effects were observed up to
1000 mg test item/kg soil dw (BASF 1996). In a chronic study with
Eisenia fetida a NOEC of 305.0 mg test item/kg soil dry weight was
determined (BASF 2012). Under the very conservative assumption that
these adverse effects are caused by the pentanolic fraction only, a NOEC
of 106.75 mg /kg soil dry weight could be extrapolated for the
pentanols. Nevertheless, we would expect that a chronic study with
Eisenia fetida on pentanol would result in a much higher NOEC
value.However, this NOEC based on worst-case assumptions has been used
for the PNECsoil derivation.
to terrestrial arthropods
substance shows no effects up to the limit concentration in acute
aquatic toxicity tests. Furthermore, the substance shows no potential
for accumulation in soil due to its ready biodegradable properties, its
LogPow value and is not ionisable. Therefore, an impact on terrestrial
organisms is very unlikely and thus, studies on soil organisms are not
to terrestrial plants
to soil microorganisms
data on terrestrial toxicity are available. However, in chapter R.10 of
the Guidance on information requirements and chemical safety assessment
(ECHA 2008, p. 42) concerning the Registration, Evaluation,
Authorisation and Restriction of Chemicals (REACH), it is laid down that
"the chemicals of concern with respect to secondary poisoning include
lipophilic organic chemicals and some metal compounds". The substance
shows a low bioaccumulative (log Pow = 1.29) potential. Thus, a relevant
and considerable exposure of birds is not expected. Therefore, and for
reasons of animal welfare studies on bird toxicity are not provided.
