Recent studies have demonstrated that statistically significant correlations of concentration measurements can be frequently found in the work environment. On this ground, possible applications of correlation-based procedures for assessment of occupational exposure to hazardous chemicals have been investigated, to find out working situations where such procedures can be advantageously used. One typical situation is occupational multiple exposure, resulting from use of mixtures of chemicals, so that the air concentration of each substance is more or less significantly correlated with concentrations of all the other substances present in the mixture.
The ideally correct method for multiple exposure assessment, consisting in complete identification and quantification of each hazardous chemical agent, is not easily applicable, for reasons of technical and economical feasibility. So, the traditional approach to multiple exposure assessment is to quantify only one (or just a few) component of the mixture.
The correlation-based approach involves quantifying one component of the mixture and estimating by statistical methods the concentrations of the other components, provided that significant correlation is proved by statistical tests through a preliminary study. Examples of correlation-based procedures are discussed, indicating their reliability as tools for estimating occupational exposure and programming intervention in workplaces.
