Description of key information

A NOEC of 111 mg/kg soil dw and an EC50 of 316 mg/kg soil dw was found for Chloramine T, this is equivalent to 83.5 and 238 mg/kg soil dw p-TSA, respectively.

Key value for chemical safety assessment

Short-term EC50 or LC50 for terrestrial plants:
238 mg/kg soil dw
Long-term EC10, LC10 or NOEC for terrestrial plants:
83.5 mg/kg soil dw

Additional information

No studies are available on this substance but one study is available on Chloramine T which is instantly converted to p-TSA in contact with organic material, therefore this study can be used here as well.

One study, valid without restrictions, is available for terrestrial plants with Chloramine T (CAS 127 -65 -1). A 21 day seedling emergence study with three plant speices was performed in natural soil mixed with quartz sand and an organic carbon content of 1.18%, according to OECD 208. Soybean was the most sensitive species and shoot height was the most sensitive endpoint. A NOEC of 111 mg/kg soil dw and an EC50 of 316 mg/kg soil dw was found for Chloramine T, this is equivalent to 83.5 and 238 mg/kg soil dw p-TSA, respectively.
