Abstract
The analysis of the volatiles evolved from a number of polymer samples commonly used in domestic applications show that carbon disulfide, CS2, and carbonyl sulfide, COS, are emitted in the
lower range of temperatures, i.e. from room temperature up to 150 °C. Emission of COS in the ppm range was also monitored from materials used in the fabrication of the teats for baby's feeding
bottles and from similar devices. Given the lack of legal tolerance limits on the toxicity of COS, it is urgent that such norms be set for this compound.
