At the same time, space-time variations of the environmental concentrations of the chemical agents can be taken into account by way of the contemporary sampling in fixed positions. The optimal duration of personal samplings is between 6 and 8 hours, because it is representative of the work shift and therefore of the potential weighted average exposure over eight hours (TWA) required for a reasonable comparison with Threshold Limit Values – Time Weighted Average (TLV-TWA). The ease of use of radiello made it possible to perform some hundreds samplings, including personal and environmental ones, in just a few working days, guaranteeing the minimum interference with the company’s production activities and the optimization of economic and temporal resources.

Atmospheric Environment, 2001, 35, Supplement No. 1, S141-S148. Emitted primarily from traffic, benzene has been identified as a carcinogen, inflicting deleterious effects on human health. This has mandated a high degree of scientific attention, both to measure ambient levels in urban regions and to explore mitigation strategies, which can form the basis of policy. In this paper, we present an overview of the most commonly used methods for measurements of atmospheric benzene. The results from field inter-comparisons involving a BTEX monitor as well as with manual pumped tube sampling and diffusive sampling are presented. Finally, monitoring strategies are discussed.
