Title Occupational exposure to arsenic, sulfur and sulfur dioxide at a natural gas desulfurisation plant
Original title Esposizione professionale ad arsenico, zolfo ed anidride solforosa in un impianto di desolforazione di gas naturale [in Italian]
Bibliographic information July-Aug. 1980, Vol.71, No.4, p.328-333. 14 ref.
Abstract A method for evaluation of the arsenic exposure is proposed: an alkaline solution of sodium arsenite and arsenate was used to eliminate hydrogen sulfide from the gas before treatment. Arsenic was analysed by flameless atomic absorption spectrophotometry after reduction to arsine. Arsenic exposure was excessive at some workplaces. Methods for determining sulfur dioxide and sulfur are also described.
