Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
