Acute/short term exposure
Hazard assessment conclusion:
medium hazard (no threshold derived)
DNEL related information
Explanation for the modification of the dose descriptor starting point:

Based on the available data, the substance is not classified for the "acute inhalation" endpoint, therefore no DNEL was calculated.
