[Pulsed method of sampling in monitoring of carcinogenic substances in gaseous atmosphere]. / Pul'satsionnyi sposob otbora prob dlia monitoringa kantserogennykh veshchestv v gazovozdushnoi srede.

Experiments using various types of gas samplers showed that application of A phi A type fibrous material-containing filters for benzo(a)pyrene monitoring may result in significant underestimation of the carcinogen level in the air. The authors developed pulsed sampler using suspended layer of sorbent which proved most effective in catching benzo(a)pyrene in gaseous atmosphere. The unit allows simultaneous sampling of carcinogenic polycyclic aromatic hydrocarbons and N-nitroso compounds.
