According to the REACH GUIDANCE 7.C Version 3.0, 2017 p.134 it is
stated: " Effects on terrestrial organisms Column 2: “these tests
do not need to be conducted if direct and indirect exposure of soil
compartment is unlikely.” .... ...In the case of readily
biodegradable substances which are not directly applied to soil it is
generally assumed that the substance will not enter the terrestrial
environment and as such there is no need for testing of soil organisms
The registered substance is readily biodegradable and has a log
KOW of -2.01. The terrestrial PNEC is deviated from a
Nitrogen-Transformation test (OECD 216).
The Nitrogen-Transformation test (OECD 216) which can be also
considered as a long term test (REACH guidance Chapter 7.C Endpoint
specific guidance R7.11.3 ) resulted in a NOEC of > 1000 mg/kg soil.
Using an assessment factor of 1000 a PNEC of 1 mg/kg soil was deviated.
Based on this value all uses in the risk assessment show a PEC/PNEC
ratio of << 1 for the terrestrial compartment indicating no need for
