摘要

Aggregated occupational sets of exposure measurements from the Norwegian industry registered in the exposure database EXPO at The National Institute of Occupational Health, Oslo were examined with respect to distributions and skewness. Data for lead in blood show a Truncated almost normal distribution because of regulations for workers with high lead in blood Concentrations. The styrene, dichloromethane and acetone measurements show quasi log-normal Distributions possibly because of over-representation of worst-case measurements.
