Title Benchmark guideline for urinary 1-hydroxypyrene as biomarker of occupational exposure to polycyclic aromatic hydrocarbons
Bibliographic information Jan. 2001, Vol.45, No.1, p.3-13. 70 ref.
Abstract Urinary 1-hydroxypyrene has been proposed as an indicator of exposure to polycyclic aromatic hydrocarbons (PAH). This article discusses a proposed three-level guideline for exposure evaluation. The first level is the 95th percentile in non-occupational exposed controls, namely 0.24µmol/mol and 0.76µmol/mol creatinine for non-smokers and smokers, respectively. Next, 1.4µmol/mol creatinine is the lowest reported level at which no genotoxic effects were found among exposed workers and is therefore proposed as the second level of the guideline. In two types of industry, coke ovens and primary aluminium production, airborne PAH concentrations and urinary 1-hydroxypyrene concentrations in exposed workers have been studied. The concentration of 1-hydroxypyrene in urine equal to the occupational exposure limit is 2.3µmol/mol creatinine and 4.9µmol/mol creatinine, respectively, in these two industries. These latter values present the third level of the guideline.
