Experiments on the effects of several factors on the 1-hydroxypyrene level in human urine as an indicator of exposure to polycyclic aromatic hydrocarbons.
The concentration of 1-hydroxypyrene in human urine was determined in six volunteers who lived under the same conditions. Samples were collected four times per day for three consecutive days; the maximum concentration of 1-hydroxypyrene was found in the samples collected late in the evening (21:00-23:00 h) which is the time recommended as suitable for determination of urinary 1-hydroxypyrene for the purpose of evaluating human exposure to polycyclic aromatic hydrocarbons (PAHs). Statistical tests show that the influence of sex, age, and smoking on urinary 1-hydroxypyrene is statistically insignificant.
