Investigation of PAH biomarkers in the urine of workers exposed to hot asphalt.
Airborne emissions from hot asphalt contain mixtures of polycyclic aromatic hydrocarbons (PAHs), including several carcinogens. We investigated urinary biomarkers of three PAHs, namely naphthalene (Nap), phenanthrene (Phe), and pyrene (Pyr) in 20 road-paving workers exposed to hot asphalt and in 6 road milling workers who were not using hot asphalt (reference group). Our analysis included basel...
متن کاملUrinary 1-hydroxypyrene and polycyclic aromatic hydrocarbon exposure among asphalt paving workers.
OBJECTIVES Using urinary 1-hydroxypyrene (1-OHP) as a measure of total absorbed dose, the primary objective of this study was to evaluate the total effect of inhalation and dermal PAH exposures while considering other factors such as age, body mass index and smoking that may also have a significant effect on urinary 1-OHP. METHODS The study population included two groups of highway constructi...
متن کاملComparing urinary biomarkers of airborne and dermal exposure to polycyclic aromatic compounds in asphalt-exposed workers.
When working with hot mix asphalt, road pavers are exposed to polycyclic aromatic hydrocarbons (PAHs) through the inhalation of vapors and particulate matter (PM) and through dermal contact with PM and contaminated surfaces. Several PAHs with four to six rings are potent carcinogens which reside in these particulate emissions. Since urinary biomarkers of large PAHs are rarely detectable in asph...
متن کاملPolycyclic aromatic hydrocarbons at fire stations: firefighters' exposure monitoring and biomonitoring, and assessment of the contribution to total internal dose.
This work characterizes levels of eighteen polycyclic aromatic hydrocarbons (PAHs) in the breathing air zone of firefighters during their regular work shift at eight Portuguese fire stations, and the firefighters' total internal dose by six urinary monohydroxyl metabolites (OH-PAHs). Total PAHs (ΣPAHs) concentrations varied widely (46.4-428ng/m3), mainly due to site specificity (urban/rural) an...
متن کاملCytogenetic biomonitoring of road paving workers occupationally exposed to polycyclic aromatic hydrocarbons.
Road pavement workers are exposed to many known carcinogens in their complex occupational environment. The study makes an attempt to investigate exposure to polycyclic aromatic hydrocarbons (PAH) from the bitumen fumes among the road pavement workers engaged in different pavement sites at Coimbatore, Tamil Nadu and to thereby determine the genotoxic effects associated with it. The study include...
