Chemical Safety Assessment in the REAC H Regulation as an element of identification and control of risk from chemical substances
Journal Title: CHEMIK nauka-technika-rynek - Year 2015, Vol 69, Issue 4
Abstract
Three basic stages of the chemical safety assessment process have been discussed in the publication: hazard assessment, exposure assessment and risk characterization. In the framework of hazard assessment among others the threshold levels for exposure considered as safe have been mentioned and discussed. By discussion concerning exposure assessment, the role of the exposure scenarios and the way of approach to the real human exposure levels and predicted environmental concentration as the reference values to the no harmful effect threshold levels have been described. Then the way of risk characterization and cyclic achievement of acceptable risk level have been talked over and, by extension elaboration of the final exposure scenario which may be applied for downstream users in the supply chain to create safe substance handling conditions – has been discussed. In this publication the elements have been made use of the “Guidance on Information Requirements and Chemical Safety Assessment” and the “Guidance in a Nutshell – Chemical Safety Assessment”.
