CONCLUSION
The test substance caused no adverse effects (deviation from control <25 %, OECD 216) on the soil nitrogen transformation (measured as NO3-N production) at the end of the 28-day incubation period. The study was performed in a field soil at concentrations equivalent up to a field application rate of 750 g a.i./ha (equivalent to 794 g test item/ha).
CONCLUSION AE 1170437 tech. caused no adverse effects (deviation from control < 25 %, OECD 217) on the soil carbon transformation (measured as oxygen consumption) at the end of the 28-day incubation period. The study was performed in a field soil at concentrations equivalent up to a field application rate of 750 g a.i./ha (equivalent to 794 g test item/ha).
Description of key information
NOEC (28 d) >= 1.06 mg a.s./kg soil dw
Key value for chemical safety assessment
Additional information
Two GLP studies are available. No adverse effects of the test substance on carbon transformation (OECD 217) and on nitrogen transformation (OECD 216) in soil were observed in both tests systems with concentrations of 0.21 mg test item/kg dry soil (corresponding to an application rate of 150 g a.s./ha = 159 g test item/ha) and 1.06 mg test item/kg dry soil (corresponding to an application rate of 750 g a.s./ha = 794 g test item/ha). Test concentrations related to a soil depth of 5 cm and a soil density of 1.5 g/cm³.
Therefore it can be concluded that the test substance caused no negative effects (deviation from control <25 %, OECD 216) on the soil nitrogen transformation (measured as NO3-N production) and also no negative effects (deviation from control <25 %, OECD 217) on the soil carbon transformation (measured as oxygen consumption) at the end of the 28-day incubation period.
A statistical analysis was performed (t-test) in order to derive the NOEC-value. Since no statistical difference resulted the NOEC (28 d) for both studies was derived to be >= 750 g a.s./ha corresponding to >=1.06 mg a.s./kg soil dw.
