Summary:Air-quality management is implemented by national monitoring networks. This implies quality assurance of analysis to ensure good traceability of the data obtained that is of great importance for data comparison on temporal and spatial scales and at national and international levels. In this aim, several tools have been established through regulation: definition of the priority pollutants to be monitored; determination of limit values; and, documented standards. These different points are presented in this article and the particular case of measurement of volatile organic compounds (VOCs) in ambient air highlighted, through discrepancies observed between reference methods, the further efforts that need to be made to achieve a better understanding of the variability of results and the need for developments to enhance air monitoring.
