Description of key information

The effects of Benzyl Salicylate on Soil Microorganisms has been determined. The NOEC was 167 mg/kg soil dry weight.

Key value for chemical safety assessment

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

Additional information

A study was conducted in order to determine possible effects of the test item on soil microorganisms through measuring microbial nitrate formation in treated versus untreated soils after 28 days of incubation. At 500 mg/kg soil dry weight, which was the highest tested concentration in this study, the test item significantly reduced the nitrate concentration in soil by 14.1% after 28 days. There were no significant differences in nitrate concentration between the solvent control and any of the test item treated soils at test item concentrations up to and including 167 mg test item/kg soil dry weight. Hence the NOEC can be considered to be ≥167 mg/kg soil dw. Due to the lacking of a dose-response relationship effective concentrations (ECx) could not be calculated.

Based on the above results, the test item, Benzyl Salicylate is considered to have no long-term adverse effects on nitrate formation in soil at concentrations up to and including 167 mg test item/kg soil dry weight.
