Exposure to air pollution from coal-fired power plants and impacts on human health: a scoping review

Communities living in proximity to coal-fired power plants (CFPPs) may be at greater risk of negative health impacts from exposure to air pollution than communities living further away. The aim of this scoping review was to provide an update on the evidence of the health risks of air pollution exposure associated with living in proximity to CFPPs and to evaluate the relationship between residential proximity and the extent of the health burden. We followed the PRISMA-ScR guidelines and searched Google Scholar, PubMed, ScienceDirect, Scopus and Web of Science for relevant studies from inception up to 31 January 2024. Fifty-six studies were included with most articles published from 2016 to 2023 (n=33, 59 %) and 35 were in high income countries (63 %). Living close to CFPPs was frequently associated with increased odds or likelihood of respiratory disorders, adverse birth outcomes and child developmental issues. Interventions such as emission control systems or total shutdown of CFPPs led to improved health among communities living near CFPPs. The review highlights the health impacts from air pollution associated with living in proximity to CFPPs and the need for policy measures to reduce air pollution by installing emission control technologies or transitioning to cleaner energy sources.
