As demonstrated by a literature search through recent years on MEDLINE, a great number of scientific reports deal with multiple exposure. However, many studies concern cases of multiple exposure where concentrations of chemical agents are not likely to be correlated. Such cases occur when multiple exposure is not due to use of mixtures of chemicals, but to simultaneous presence in workplaces of contaminants originating from different sources. As a consequence, concentrations of chemicals are expected not to be correlated, but to vary independently from each other, as a function of individual emitting sources or working operations.
A series of working activities where correlated concentrations are very likely to be found is grouped in Table 1 with the following specifications: (a) type of working activity, with bibliographic references; (b) chemical agents responsible of multiple exposure; (c) monitoring method (E.C.: by determination of each component; I.S.: by determination of an index substance; A.I.S.: by determination of an added index substance; T.A.: by determination of total amount; P.M.: by predictive model).
It is remarkable that use of correlation-based methods for multiple exposure monitoring is reported just in two studies (10,13), although from the point of view of feasibility it is likely to be more advantageous than the adopted methods , at least for routine exposure monitoring. Of course determination of each component of the mixture is the ideally correct technique , but it is not easily applicable for routine exposure monitoring.
