Establishing a baseline of published air pollution and health research studies in the Waterberg-Bojanala Priority Area

Abstract

An umbrella review study was conducted to establish a baseline of published air pollution and health research studies in the Waterberg-Bojanala Priority Area (WBPA). Forty peer-reviewed research studies were included based on the systematic search criteria. Less than ten studies considered air quality and health in the WBPA (as opposed to only air quality) and of these studies, only a few collected human health data in relation to air pollution exposure. Identified studies together showed that air quality is a problem in the WBPA, with ambient air quality levels often exceeding national ambient air quality standards. Based on the findings, we recommend that more focused health studies be conducted in the WBPA to better understand the air pollution-related health burden at the population and the individual level. Such studies will help bolster the baseline evidence of the impacts of air pollution on human health and wellbeing in the WBPA and support decision-making in the future.
