The purpose of this study was to provide an overview of research performance, trends and evolution in the field of ambient air quality monitoring and management in South Africa over the last decade (2010-2021) through the application of a bibliometric approach and a data mining software VOS...
South AfricaIn accordance with the Clean Air Act, the U.S. Environmental Protection Agency (EPA) is currently reviewing its National Ambient Air Quality Standards for particulate matter, which are required to provide an adequate margin of safety to populations, including susceptible subgroups. Based ...
Part 3 examines current exposure standards, applicable laws, and future directions. It is time to recognize ambient EMF as a novel form of pollution and develop rules at regulatory agencies that designate air as ‘habitat’ so EMF can be regulated like other pollutants. Wildlife loss is often ...
Remarkably, although the average PM2.5 concentrations in both areas exceed the current guidelines of the World Health Organization (WHO) for ambient PM2.5 (10 μg/m3 annual mean and 25 μg/m3 24-hour mean), as for the national ambient air quality standards of China, the average PM2.5...
Metrologically traceable and highly accurate N2O gas standards are required to understand the behaviour of the greenhouse gases in the atmosphere and GWP. A group of primary standard gas mixtures (PSGMs) in aluminium cylinder material has been prepared in synthetic air for the calibration of ...
We then compared PM 2.5 concentrations in the study domain before and after the implementation of the new national air quality standards. We aimed to test whether machine learning models are suitable for regions with sparse ground observations such as South Africa and which predictors played ...
The pollutants never exceeded the daily nor annual South African Ambient Air Quality Standards (Figure A3, Appendix) [3,9]. However, PM10 and SO2 levels exceeded the more conservative daily World Health Organization (WHO) Air quality guidelines on 120 and 327 days, respectively (Figure A3) [3...
Since the discovery of modern electric air conditioners by Willis Carrier, there are now ~2 billion air conditioning units that have been installed globally [1]. The use of air conditioning has improved living standards by reducing heat exposure and providing comfortable indoor conditions. Hence, it...
