Title Evaluation of occupational exposure to polycyclic aromatic hydrocarbons by analysis of urinary 1-pyrenol
Original title Valutazione dell'esposizione professionale ad idrocarburi policiclici aromatici mediante l'analisi del livelli urinari de 1-pirenolo [in Italian]
Bibliographic information May-June 2000, Vol.91, No.3, p.192-205. 40 ref.
Abstract Occupational exposure to polycyclic aromatic hydrocarbons (PAH) was assessed by analysing urinary levels of 1-pyrenol. A total of 231 non-smokers exposed to PAH (in industries and occupations including fuel oil power plants, used oil recovery, rubber production, road surface asphalting operations, aluminium anodizing, chimney-sweeping and coke-oven production) were enrolled, together with 53 non-smoker unexposed controls. In the overall population (controls and exposed), multiple linear regression analysis showed that levels of urinary 1-pyrenol were significantly influenced by occupational exposure to PAH in asphalt workers, anodizing plant workers, chimney-sweeps, and coke-oven workers, but not in power plant workers, workers recovering exhausted oils, or rubber production workers. In chimney sweeps and top side coke-oven workers, respectively 2 and 4 subjects exceeded the precautionary level of 1.4Ámoles 1-pyrenol/mole of creatinine; of these, 1 chimney sweep and 3 top side workers exceeded the recommended biological threshold of 2.3Ámoles 1-pyrenol/mole of creatinine.
