[Inhalation of carbon disulfide--studies of carbon disulfide uptake in dynamic dose administration lasting 4 hours]

Experiments of CS2 inhalation were accomplished with both constant loads at the ergometer combined with constant concentration of inhalation and discontinuous offered doses combined with various physical loads during 240 minutes. The conditions of the experiment were approximated to the real conditions of exposure at a viscose rayon fibres production. The intake of CS2 increased by 20 percent in case of various conditions. The cause of this finding is a different adaptation during the intake phase in opposition to the breath off phase. The profile of the exposure affected by changed CS2 concentrations and various physical activities is decisive for the intake dosage and thus for the health risk.
