The assessment factor of 10 is applied
to the most critical long-term effect parameter obtained (NOEC of 5.6
mg/L), resulting in a PNECaqua-freshwater of 0.56 mg/l:
PNECaqua-freshwater = 5.6 mg/L
/ 10 = 0.56 mg/L.
Considering marine water, the same
data can be used for the hazard assessment, however, all assessment
factors are tenfold higher compared to freshwater conditions (refer to
ECHA (2008) “Guidance of Information Requirements and Chemical Safety
Assessment, Chapter R.10: Characterisation of dose-response for
environment”; Table R.10-5):
PNECaqua-marine water = 5.6
mg/L / 100 = 0.056 mg/L.
test item needs not to be classified according to Regulation EC No
