The biological monitoring of those exposed to 1,1,1-trichloroethane : a longitudinal study
Data on long-term biological monitoring in two groups of workers engaged in cleaning operations in a wool factory and exposed to methylchloroform are presented. The longitudinal survey lasted one year and brought about 19 random systematic sampling (once or twice a month for everyone of the 13 subjects monitored). The biological marker adopted was the urinary concentration of the solvent as such, according to a previously studied method. The collected data allowed to measure: the annual average level of exposure (estimated by the long term geometric mean); the day to day variation of the true daily exposure averages (estimated by the geometric standard deviation); the probability of overexposure (daily exposures exceeding the biological exposure limit) and the yearly number of work shifts of overexposure. The usefulness of performing long-term surveys of occupational exposure to the chemical substances by mean of longitudinal biological monitoring is discussed.
