PNECs were calculated automatically using the available PNEC calculator.
Most of the key values used as input consist of limit values at 100
mg/L, where no adverse effect was observed. Consequently, the calculated
PNECs are too low. However, as the submission substance is not
classified according to Regulation No (EC) 2008/1272 in any of the
hazard classes, no exposure assessment must be performed according to
REACH Article 14 (4). Therefore, the PNECs were kept as such.
Classification according to Regulation (EC) No 2008/1272 (CLP Regulation)
Acute hazard category
There are adequate short-term studies available covering three trophic
levels, i.e. algae, daphnia and fish. The submission substance does not
need to be classified for the environment according to Regulation No
(EC) 2008/1272, based on the available acute toxicity data.
Chronic hazard category
There is one adequate long-term toxicity study available, i.e. for algae
(72h-NOErC (Pseudokirchneriella subcapitata, growth rate) >= 100 mg/L).
Furthermore, available acute toxicity data do not include any EC50 <=
100 mg/L, and the submission substance is rapidly biodegradable and the
log Kow is far below 4. According to Regulation (EC) 2008/1272, the
submission substance does not need to be classified for long-term
In conclusion, the submission substance in not classified as hazardous
for the environment.
