Application of Chemical Mass Balance Methodology to Identify the Different Sources Responsible for the Olfactory Annoyance at a Receptor-Site

摘要

The olfactory annoyance perceived at a receptor site of an industrial area is often the result of a combination of different smells, emitted by several industrial sources. The major issue in the case of complaints is to identify the main responsible of such pollution. For this purpose, tools able to determine the contribution of each source directly where the annoyance is perceived would simplify this identification. In this work, we use the source-receptor model CMB (Chemical Mass Balance) generally used for air pollution studies, by applying it for the first time to odour signatures. The contributions of VOC sources, coming from a waste treatment plant containing 3 potential sources of olfactory annoyance (waste storage, production of biogas, and compost piles of green wastes), and perceived at a village located downwind, are studied by chemical analyses and finally compared to olfactometric methods.
