Comparaison and analyse of environmental emission/exposure scenario on coating industry
Résumé
An Emission Scenario Documents (ESD) describes the sources, production processes, pathways and use patterns of a chemical. Considering the whole life of the substance, an ESD aims to provide a method of estimating emission quantity in the absence of sufficient empirical data and to provide data on each parameter. In July 2009, OECD has developed an ESD about coating industry (ESD number 22). For this ESD, the industry category relevant is IC 14 and includes paints, lacquers and varnishes in industrial uses. In September 2009, Japan authorities provided an addendum intended as a complement to the method used in the ESD No.22, it treats about solvent substances and focus on industrial coating processes but contains also wood products on document. It should be noted that ESD number 22 doesn't include specific uses such as in wood preservation treatment. However, an emission scenario dedicated to wood preservatives has been developed by the OECD Task Force on biocides (revised in 2012). In the context of REACh, Specific Environmental Release Categories (SpERCs) have been developed by the industry to comply with the REACH requirements for ERC (Environmental Release Categories) associated with paint application in certain industries. We propose to compare the different exposure scenarii quoted previously each other in a practical case. Pros and cons will be discussed.
