Description of key information

Chloramine B trihydrate is not intended for disinfection of soil and solid waste, but it is used in industrial, professional and private facilities. Hence a direct contamination of soil is unlikely.
Indirect contamination of the soil environment is unlikely, too, for the following reasons.
Chloramine B trihydrate is not biodegradable (see DOC IIIA 7.1.1.2). However, during its application and its discharge in wastewaters, complete degradation occurs by fast dechlorination (see DOC III-A_7.3.3_1 and DOC III-A_7.3.3_2), The dechlorinated form of Chloramine B, benzenesulphonamide (BSA), is readily biodegradable (see DOC IVA / A29 and A30). Hence at the proposed use concentrations, chloramine B trihydrate degrades completely and does not enter the environment.
As the substance – via fast dechlorination to its metabolite BSA – is readily biodegradable, further investigations with respect its fate and effects in soil ecosystems are obsolete.
