In occupational hygiene surveys and occupational epidemiology studies correlation-based techniques may be a helpful tool for assessment of exposure to chemical hazards. Working situations where concentrations of contaminants are expected to be highly correlated with each other are frequent: among them use of mixtures of chemical substances or elements. Whenever correlation of concentrations is statistically significant (for instance between individual contaminants in case of use of mixtures) occupational exposure may be monitored by measurement of just one chemical, as concentrations of the other contaminants can be estimated through statistical correlation and regression.
The drawback to applying these methods is the need for a preliminary survey to collect data for statistical correlation testing. However, it is compensated for by a consistent decrease in number of required measurements for routine exposure monitoring, as recommended in compliance control programs for certain chemical hazards and in occupational epidemiology studies.
