Ozone is one of the most important pollutants in South Africa. During 2014, all of the monitoring sites in the Vaal Triangle and Highveld priority areas were out of compliance with the National Ambient Air Quality Standards for ozone in terms of the number of reported exceedances. In South Africa, the focus of concern relating to ambient ozone has largely been in relation to human health, however, it has long been known that high levels of ambient ozone have a large detrimental effect on agricultural productivity. Recently, a number of articles have been published regarding the impact of ozone on agriculture and two of these are highlighted below.
