- Executive summary:
In Advisory Board for Environmentally Relevant Existing Substances (BUA);2000 report the ecotoxicological and toxicological aspect of chemical was studied.
According to report the effect concentration (EC0) for bacteria Escherichia coli was observed to be 50 mg/l for 96 hrs exposure period. Based on the effect concentration it may considered that the test chemical may have aquatic toxicity concern to micro organism at higher dose concentrations for acute exposure.

Description of key information
In Advisory Board for Environmentally Relevant Existing Substances (BUA);2000 report the ecotoxicological and toxicological aspect of chemical N-Benzyl-N-ethylaniline (BEA) was studied.According to report the effect concentration (EC0) for bacteria Escherichia coli was observed to be 50 mg/l for 96 hrs exposure period.Based on the effect concentration it may considered that the test chemical N-Benzyl-N-ethylaniline (BEA) may have aquatic toxicity concern to micro organism at higher dose concentrations for acute exposure.
Key value for chemical safety assessment
Additional information
Two studies including experimental data from peer reviewed journal and authorative database for toxicity to micro organism endpoint of test chemical N-benzyl-N-ethylaniline (Cas no. 92-59-1) with relevant read across which is close to target by structure were summarised as follows:
First study of target from secondary source Advisory Board for Environmentally Relevant Existing Substances (BUA) which suggests the ecotoxicological and toxicological aspect of chemical N-Benzyl-N-ethylaniline (BEA) was studied and according to report the effect concentration (EC0) for bacteria Escherichia coli was observed to be 50 mg/l for 96 hrs exposure period.Based on the effect concentration it may considered that the test chemical N-Benzyl-N-ethylaniline (BEA) may have aquatic toxicity concern to micro organism at higher dose concentrations for acute exposure.
And peer reviewed journal Toxicology methods, 7, 289-309; 1997 for read across chemical N,N-diethylaniline (Cas no.91 -66 -7) indicate the 50 percent growth impairment concentration (IGC 50) of N,N-diethylaniline in the micro-organism Tetrahymena pyriformis during a 48 hr study was reported as 0.67mg/L.The observed growth impairment concentration suggest that the chemical N,N-diethylaniline (Cas no.91 -66 -7) may have concern to toxicity to micro organism for acute exposure period.
Both experimental study of toxicity to micro organism give the conclusion that the test chemical N-benzyl-N-ethylaniline (Cas no. 92-59-1) may have toxicity concern for acute exposure.
