Biological monitoring of exposure to polycyclic aromatic hydrocarbons by determination of unmetabolized compounds in urine.
In this paper we evaluated the possibility to assess occupational exposure to polycyclic aromatic hydrocarbons (PAHs) measuring unmetabolized PAHs in urine. With this aim, 24 road paving (RP) workers, exposed to bitumen fumes, and 6 road construction workers (CW), exposed to diesel exhausts, were investigated. Median personal exposure to low boiling PAHs (from naphthalene to pyrene) during the ...
متن کاملSimultaneous Monitoring Method of Polycyclic Aromatic Hydrocarbons
intentionally manufactured or synthesized, as well as dioxins; however, they exist in fossil fuels, such as petroleum and coal. They are organic pollutants produced unintentionally by the combustion of organic compounds, like fossil fuels and waste. Especially, PAHs are formed during incomplete combustion; some PAHs, such as benzo(a)pyrene, have high carcinogenicity and mutagenicity for humans ...
متن کاملUsing liquid chromatography-tandem mass spectrometry to quantify monohydroxylated metabolites of polycyclic aromatic hydrocarbons in urine.
We present an assay which employs enzyme digestion and solid phase extraction followed by liquid chromatography-tandem mass spectrometry to simultaneously quantify 16 hydroxylated polycyclic aromatic hydrocarbons (OHPAHs) in 3-ml samples of urine. The analytes consisted of 2-, 3-, and 4-ring OHPAHs, namely, 1- and 2-hydroxynaphthalene (1- and 2-OHNAP), 2-hydroxyfluorine (2-OHFLU), 1-, 2-, 3-, 4...
متن کاملBiodegradation of Polycyclic Aromatic Hydrocarbons (PAHs) in Petroleum Contaminated Soils
Polycyclic aromatic hydrocarbons are a class of potentially hazardous chemicals of environmental and health concern. PAHs are one of the most prevalent groups of contaminants found in soil. Biodegradation of complex hydrocarbon usually requires the cooperation of more than single specie. In this research biotreatment of PAH (phenanthrene) was studied in a solid-phase reactor using indigenou...
متن کاملTransport of Polycyclic Aromatic Hydrocarbons in a Calcareous Wetland Soil
Knowledge of transport and degradation of polycyclic aromatic hydrocarbons (PAHs) is important in assessing PAH contamination of soils and water resources. The transport of naphthalene, anthracene, pyrene and phenanthrene was determined in a contaminated calcareous soil obtained from the Shadegan wetland (Khozestan, Iran) considering a column study in laboratory conditions. The PAHs were added ...
