The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

A 42-day soil toxicity test was carried out to investigate the long-term effects of the registered substance, the rection products of 1-decene, 1-dodecene and 1-octene, hydrogenated, on the nitrogen transformation activity of soil microorganisms.  Results from the study indicated that the registered substance caused no long-term adverse effect to soil micro-organisms under the conditions of the OECD 216 test, at soil concentration of 100 mg/kg (dw).  

Key value for chemical safety assessment

Long-term EC10 or NOEC for soil microorganisms:
100 mg/kg soil dw

Additional information

In a GLP study conducted according to OECD 216 guidelines, the registered substance was evaluated at soil concentrations of 0, 1, 10 and 100 mg/kg dry weight (d.w.) to determine the effect on the transformation of an organic nitrogen source (lucerne) to nitrate over a period of 42 days in soil micro-organisms. No statistically significant difference in the 0 -42 day nitrate formation rate was seen in the 1, 10 or 100 mg/kg soil dw concentration group compared to that in the control soil group, indicating that the 42 -day no-observed-effect concentration (NOEC) was > 100 mg/kg (dw). The 42 -day EC50 was also >100 mg/kg (dw). There was no dose-response over the exposure levels investigated. In summary, the registered substance showed no long-term effect to soil micro-organisms under the conditions of the OECD 216 test, even at the highest nominal soil concentration of 100 mg/kg (dw). Clearly these findings indicate that the registered substance is not expected to cause any long-term effects to soil microorganisms.
