Additional information

Based on the value aquired from peer reviewed journal,long term toxicity of aquatic invertebrates was discribed as below:

Long term toxicity study was conducted to test the effects of 1-chloro-3-nitrobenzene on daphnia magna for 14 days .Based on the immobilization the LC50 and EC50 was determined to be 22.1mg/l and 3.82mg/l respectively.

Long term toxicity study was conducted to test the effects of 1-chloro-3-nitrobenzene on fresh water invertebrates daphnia magna for 21 days. Feeding was provided to the daphnids 3x108C.pyrenoidosa cells/l/day.Based on the mortality the LC50 was determined to be 2.0mg/l for 21days chronic exposure. The substance may not be classified as it is chronic study.

Based on the effect concentrations we can consider that the test substance 1-chloro-3-nitrobenzene has no chronic effect on aquatic invertebrates and can be considered as not classified as per CLP.
