Title Occupational exposure to arsenic in a chemical plant: Health hazard evaluation after elimination of arsenic from the process
Original title Esposizione professionale ad arsenico in un impianto chimico: Valutazione del rischio dopo eliminazione dell'arsenico dal ciclo tecnologico [in Italian]
Bibliographic information Nov.-Dec. 1981, Vol.72, No.6, p.473-479. Illus. 17 ref.
Abstract In 1978 an alkaline solution of sodium arsenite was used to remove hydrogen sulfide from natural gas in a chemical plant. Arsenic (As) was eliminated from the desulfurisation process in 1979 and environmental contamination by As was determined in 1981. Air concentrations were in the range 0.0005 - 0.125Ág/m3, well below recommended safety levels. Concentrations of <2540mg/m2 were found in ground samples extracted with 2% sodium carbonate solution. In a soil core sample the As value was 0.55▒0.09mg/kg at 0.6-1.8m depth but decreased from floor level to 0.6m depth.
