Biological Monitoring of Occupational Exposure to Polycyclic Aromatic Hydrocarbons at an Electric Steel Foundry in Tunisia.
Occupational exposures during iron and steel founding have been classified as carcinogenic to humans, and the exposure to polycyclic aromatic hydrocarbons (PAHs) in this industrial setting may contribute to cancer risk. The occupational exposure to PAHs was assessed in 93 male workers at an electric steel foundry in Tunisia by biomonitoring, with the aims of characterizing the excretion profile...
متن کاملAmbient and biological monitoring of cokeoven workers: determinants of the internal dose of polycyclic aromatic hydrocarbons.
Polycyclic aromatic hydrocarbons (PAH) were measured in the breathing zone air of 56 battery workers at two cokeovens during three consecutive days. The concentration of total PAH ranged up to 186 micrograms/m3. Preshift and end of shift urine samples were collected to determine 1-hydroxypyrene, a metabolite of pyrene. Control urine samples were available from 44 workers in the shipping yard of...
متن کاملInteraction of smoking, uptake of polycyclic aromatic hydrocarbons, and cytochrome P450IA2 activity among foundry workers.
An increased lung cancer risk has been described among foundry workers. Polycyclic aromatic hydrocarbons (PAHs) and silica are possible aetiological factors. This study describes a urinary PAH metabolite, 1-hydroxypyrene (hpU), as well as the degree of cytochrome P450IA2 activity/induction as reflected by the urinary caffeine ratio (IA2) in 45 foundry workers and 52 controls; IA2 was defined as...
متن کاملDeterminants of benzo(a)pyrenediol epoxide adducts to haemoglobin in workers exposed to polycyclic aromatic hydrocarbons.
OBJECTIVE The aim was to assess the determinants of benzo(a)pyrenediol epoxide adducts to haemoglobin (BaPDE-Hb) in workers exposed to polycyclic aromatic hydrocarbons (PAHs). METHODS This was a study of the correlations between the concentrations of PAHs in air, 1-hydroxyprene in urine, and BaPDE-Hb adduct concentration in the blood in 206 men working in steel foundries and one graphite elec...
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 ...
