Justification for type of information:
Carbon disulphide is both a reagent in the manufacture, as well as a decomposition product of xanthates. SIBX readily decomposes to carbon disulphide, especially in the presence of moisture/water. Therefore, the health effects of carbon disulphide (CS2) need to be considered in the assessment of SIBX.

A study of NC-NC Not Coded duration using no substrate media was conducted in a FIELDN site location with Not Coded obtained Apis mellifera (Honey Bee). The organism(s) (age: NR NR and organism characteristics of: NR) were exposed for a duration of 1 hour(s) to a(n) 1 dosed x time(s) per study periodapplication of Carbon disulfide (CAS # 75150) in NR or a(n) NR positive control through a(n) hand spray exposure route. The reported chemical concentrations are the result of unmeasured analysis of chemical solutions and are based on the NR ion. (Reference 81711, Mayer,D.F., J.D. Lunden, G. Kovacs, and E.R. Miliczky, 2001, Test Number 571193)

A study of NC-NC Not Coded duration using no substrate media was conducted in a LAB site location with Not Coded obtained Sitophilus oryzae (Rice Weevil). The egg(s) (age: 2 d and organism characteristics of: NR) were exposed for a duration of 7 hour(s) to a(n) 1 dosed x time(s) per study period application of Carbon disulfide (CAS # 75150) in NR or a(n) NR positive control through a(n) fumigation exposure route.
