3-chloroaniline

Toxicity to soil macroorganisms except arthropods

Description of key information

The lethal concentration (LC50) of 3-chloroaniline in soil macroorganism (Allolobophora tuberculata) in a short term study of 48 hrs study on the basis of mortality effect was estimated to be 169.22 mg/kg soil dw.

Key value for chemical safety assessment

Short-term EC50 or LC50 for soil macroorganisms:

169.22 mg/kg soil dw

Additional information

No. of studies were reviewed for toxicity to soil macroorganisms except arthropods from reliable sources having Klimisch rating 2 and 4.

The summary of the results are presented below  

 

Sr.No	Endpoint	Effect values	Basis for effects	Duration	Species	Sources
1	LC50	169.22 mg/kg soil dw	Mortality	48 hrs	Allolobophora tuberculata	Predicted data from QSAr for CAS : 108-42-9
2	EC50	90-270 mg/kg soil dw	Reproduction	56 days	Eisenia fetida	Experimental data from J. Soils Sediments for RA CAS : 95-76-1

 

Based on the studies summarized in the above table for the target substance 3-chloroaniline and the read across substance 3,4-dichloroaniline in a soil macroorganisms (Allolobophora tuberculata and Eisenia fetida),the endpoint value was found to vary between the lethal concentration (LC50) = 169.22 mg/kg soil dw and effective concentration (EC50) = 90-270 mg/kg soil dw in a 48 hrs study to 21 days study on the basis of mortality and reproduction effect.
