Conclusion on classification
The short-term toxicity of 2-chlorotoluene towards aquatic organisms is characterized based on acute data by an EC50(48 h) of 0.70 mg/L having the immobilization of Daphnia magna as the most sensitive endpoint. Furthermore, the test item is not readily biodegradable and has a low potential to bioaccumulate in aquatic organisms.
According to REGULATION (EC) No. 1272/2008 (CLP) the substance is classified as:
Very toxic to aquatic life (H400) with regard to the acute aquatic hazard class, i.e. Category Acute 1.
An acute M factor of 1 applies.
Chronic data are available for the acutely most sensitive trophic level aquatic invertebrates (Daphnia magna), as well as algae (pronouncedly lower chronic sensitivity observed). Based on the relevant
NOEC (Daphnia magna; 21 d; reproduction; semi-static; TWM) = 0.313 mg/L
and considering that the substance is not rapidly degradable, according to REGULATION (EC) No. 1272/2008 (CLP) the substance is classified as:
Toxic to aquatic life with long-lasting effects (H411) with regard to the long-term aquatic hazard class, i.e. Category Chronic 2.
No M factor applies for a NOEC > 0.1 mg/L
Reliable chronic data for the third trophic level fish are missing. Supporting not assignable data indicate a 30-day NOEC of 1.4 mg/L. This supports chronic hazard classification based on the reliable chronic result for the more sensitive aquatic invertebrate Daphnia magna. Further, using the acute fish toxicity result (96 h LC50 = 7.7 mg/L) as the basis for aquatic chronic hazard classification, again Category Chronic 2 is resulting, corroborating the assessment based on available chronic data given above.
The acute hazard classification as outlined above thus differs from the harmonised classification according to Annex VI of Regulation (EC) No 1272/2008 (CLP Regulation; ATP CLP00), where no environmental classification for acute aquatic hazards does exist. The chronic aquatic hazard category (Cat. 2) according to the harmonised classification is in agreement with the self-classification outlined above.
