[Occupational risk during chemical exposure]

Methods for assessing the occupational risk were tested in chemically exposed workers at some enterprises by taking into account a priori and a posteriori components. The risk values were calculated by the indices of collective and individual health, which were used to develop conceptual models for the assessment and management of risks, whose efficiency may be evaluated. A package of measures has been worked out to reduce human health occupational risks. Practice has shown that the developed methods for assessing the occupational risk upon chemical exposure await further development and improvement.
