Evaluation of Particulate Matter (PM2.5) Levels in Major Cities of Pakistan: A Review

Level of P.M 2.5 in major cities of Pakistan

Abstract

Air pollution is considered one of the most concerning problems of the world. Everyone is getting affected by the hazardous
impacts of air pollution and environmental changes occurring with time and causing adverse effects on human beings and
global climatic conditions as well. This review aims to document an analysis of the particulate matter PM2.5 levels in
Pakistan. Particulate matter (PM10 & PM2.5) is considered the most known cause of air pollution either indoor or outdoor
station. Many epidemics and disorders are associated with the emission of PM in our atmosphere through various causes.
PM can cause aerial pollution in indoor and outdoor areas and have negative effects on both fauna and flora. All types of
PM are equally hazardous to living beings and the earth’s atmosphere. PM presence in the environment poses great health
effects not only on humans but also contributes to regional and global warming. Pakistan is also facing PM pollution.
Most prominently, mega cities of Pakistan show more data in terms of ambient air pollution analysis. Among them, PM2.5
is the focus of study in this review, to assess the evaluated data gathered in the past few years of research-based studies
conducted in different cities of Pakistan. Moreover, some light has also been thrown upon a few solution steps to minimize
PM2.5 impacts. In conclusion, addressing PM2.5 pollution in Pakistan is imperative to protect public health and mitigate
environmental degradation.
