Title Autocorrelation of interday exposures at an automobile assembly plant
Bibliographic information Dec. 1995, Vol.56, No.12, p.1187-1194. Illus. 14 ref.
Abstract Serial 8-hr TWA exposures were obtained for six automobile assembly plant workers performing tasks involving the use of either isopropyl alcohol or hexane. Exposures were monitored for periods ranging from 20 to 110 consecutive days. Relatively little autocorrelation in the values was observed. The study highlights potential difficulties in autocorrelation analysis. In particular, nonrandom events, such as ventilation and process changes and extended down times, should be considered in any such analysis. Since exposure distributions vary over time, samples collected across the full range of procedures, activities and environmental conditions should be included when developing an exposure assessment strategy.
