||Determination of firefighter exposure to polycyclic aromatic hydrocarbons and benzene during fire fighting using measurement of biological indicators
||May 2002, Vol.17, No.5. p.379-386. Illus. 32 ref.
||Exposure to polycyclic aromatic hydrocarbons (PAH) and benzene among firefighters was assessed by means of urinary measurements of 1-hydroxypyrene and trans,trans-muconic acid (TTMA), respectively. All urine samples were collected from 43 firefighters during a period extending for 20h following the end of exposure during a fire. A control sample was also obtained from each participant after at least four days without involvement in fire fighting activities. Following exposure to fire, the level of 1-hydroxypyrene exceeded 0.32Ámol/mol creatinine value in 38% of the cases. 17 firefighters had measurable TTMA in the urine samples, among which only 6 had concentrations exceeding 1.1mmol/mol creatinine considered to correspond to a benzene concentration of approximately 1ppm. The low exposure evaluations could be due to either low concentrations of the contaminants during fire fighting or to the efficiency of protective equipment worn.
