Proposal of a model for chemical risk preliminary assessment

摘要

Chemical risk assessment is an increasing problem in the industrial environment due to the particular nature of the risk. The need to measure the concentration of chemical substances, moreover, may cause additional costs for assessment. So, the main problem that arises is to avoid sampling and measuring campaigns whenever possible. This objective can be achieved using a more reliable assessment model, like the one proposed in this paper. The aim of this paper is to describe the model, which is based on the assumption that the concentration of chemical agents has a log-normal distribution, and to discuss its increased reliability features.
