Description of key information

The toxicity of 4 -chlorotoluene towards microorgansims was tested by the means of Pseudomonas putida growth inhibition yielding an  EC10(18 h) of > 25 mg/L (Trenel 1982).
The toxicity of 4 -chlorotoluene towards microorganisms was investigated by the means of the lethal response of Spirostomum ambiguum yielding a LC50(48 h) of 110.8 mg/L (Nalecz-Jawecki, 2002).

Key value for chemical safety assessment

EC50 for microorganisms:
110.8 mg/L
EC10 or NOEC for microorganisms:
25 mg/L
