Description of key information

The effect concentration of a 28-days study to respiration activities of soil microflora is > 400 mg/kg soil dw.

Key value for chemical safety assessment

Additional information

Effects of sulfur dust on the activity of soil microflora in the laboratory were studied in a GLP compliant OECD guideline 216/216 study (Institute für Biologische Analytik und Consulting IBACON GmbH, 2005e). Based on the results of the available study, sulfur dust has no impact on respiration activities (measured as effects of O2-consumption after 28 days of exposure; effects on NO3-nitrogen production after 28 days exposure) of soil microflora (biologically active agricultural soil: loamy sand) when applied up to 400 mg/kg soil dry weight (corresponding to 10 times the maximum recommended application rate of 30 kg sulfur dust per ha).
