Conclusion on classification

2,3 -xylenol is harmonised classified Aq. Chronic 2.


 


Short-term (acute) aquatic hazard



  1. LC50 aquatic invertebrates (Daphnia magna): 2.892 mg/L

  2. ErC50 algae: > 10 mg/L


No classification for Aq. Acute 1 is warranted since the LC50 for crustacea and ErC50 for algae are > 1 mg/L.


 


Long-term (chronic) aquatic hazard


Chronic toxicity data:


NOEC algae: 0.0316 mg/L based on growth rate inhibition.


 


Acute toxicity data:



  1. LC50 aquatic invertebrates (Daphnia magna): 2.892 mg/L

  2. ErC50 algae: > 10 mg/L


2,3 -xylenol is predicted to be not readily biodegradable. Based on this prediction and the observed aquatic toxicity (NOEC algae < 0.1 mg/L), an Aq. Chronic 1 classification is warranted.
