A key tool for understanding the impacts of atmospheric pollution is through the long term measurement of the ambient concentrations of criteria atmospheric pollutants. Monitoring of ambient pollution concentrations has been conducted in the National Air Quality Priority areas since 2009. During this time period, significant changes in the management of air pollution have occurred, including the adoption of the ambient air quality standards, and the implementation of section 21 emission standards. This paper examines the long term evolution of ambient concentrations for PM, SO<sub>2</sub> in the Vaal Triangle Airshed Priority Area 2007-2017 and Highveld Priority Area. These trends will be evaluated against the implementation of management interventions and highlight the variation in the measured concentrations and emerging areas of concern.  </p>}, number={2}, journal={Clean Air Journal}, author={Feig, Gregor and Garland, Rebecca M. and Naidoo, Seneca and Maluleke, Amukelani and Van der Merwe, Marna}, year={2019}, month={Dec.} }
