[Correlation between exhaled benzene and environmental exposure in refinery workers]. / Correlazione tra il dosaggio del benzene nell'aria alveolare ed i livelli ambientali nei lavoratori di una raffineria.

Benzene is still present in various working processes. Many methods are available for the biological monitoring of benzene exposure. The Authors present a study concerning a series of 23 workers of a refinery exposed to benzene. The measurement of benzene in alveolar air was preferred to quantify exposure. In this paper, adopting an original, simple and reliable device to collect the samples of alveolar air, a good correlation was found between the levels of benzene in the alveolar air and the environmental individual sampling.
