OBJECTIVES This study evaluated the levels of exposure to polycyclic aromatic hydrocarbons (PAHs) and their relationship with oxidative DNA damage among Vietnamese coke-oven workers. METHODS We collected urine from 36 coke-oven workers (exposed group) at the beginning and end of the shift on 2 consecutive days. We also collected urine from 78 medical staff (control group). Information was col...
DNA repair is an essential mechanism for cells to maintain their genomic integrity under endogenous or exogenous assault. Reduced DNA repair capacity (DRC) is associated with increased risk for several environmentally related cancers. The micronucleus in peripheral lymphocytes has been validated as a biomarker of chromosomal damage, increasing cancer risk in human populations. We hypothesized t...
The state of deadman in hearth is important for the long campaign life blast furnace (BF). In order to clarify influence on sidewall erosion, corresponding relationship between shape and erosion was studied, fundamental reason difference analyzed, mechanism slag-coke interface iron-coke coke explored based phase distribution deadman. results show that: circumferential bulge at root a common fea...
Coke-oven workers are exposed to high concentrations of coke-oven emissions, which are comprised mainly of polycyclic aromatic hydrocarbons. We conducted a pilot study to determine the time changes in urinary 1-hydroxypyrene (1-OHP) concentrations, as a metabolite of pyrene, in coke-oven workers after exposure to a benzene-soluble fraction (BSF) of total particulates. Thirteen subjects, includi...
