Title Aromatic and polycyclic hydrocarbons in air and their urinary metabolites in coke plant workers
Bibliographic information Nov. 1998, Vol.34, No.5, p.445-454. Illus. 51 ref.
Abstract Concentrations of benzene, toluene, naphthalene, xylenes and 14 different polycyclic aromatic hydrocarbons (PAHs) were measured in various parts of a coke plant by personal air sampling; concentrations of o-cresol, 1- and 2-naphthol, methylhippuric acid and 1-hydroxypyrene were determined in the post-shift urine of workers. Results showed that these workers were simultaneously exposed to a mixture of aromatic and polycyclic hydrocarbons present in breathing zone air. While exposure levels were low compared to exposure limits, exposure was significantly influenced by job category. Compounds identified in the urine appeared to be the products of the hydroxylation of aromatic hydrocarbons present in the air as well as unmetabolized hydrocarbons. A correlation was observed between inhaled toluene, naphthalene and xylene and urinary excretion of metabolites. Topics: aromatic hydrocarbons; p-xylene; m-xylene; toluene; benzene; naphthalene; o-xylene; coking plants; determination in air; determination in urine; exposure evaluation; gas chromatography; job-exposure relation; mass spectrometry; personal sampling; polycyclic hydrocarbons; urinary metabolites.
