ABSTRACT

Atmospheric haze, a complex air pollution phenomenon comprising particulate matter and gaseous pollutants, has emerged as a critical threat to human health amid rapid industrialization and urbanization. This paper examines the composition, sources, and health impacts of haze, highlighting PM2.5 as the primary toxic component. PM2.5 penetrates deep into the respiratory system, carrying heavy metals and toxic organic substances, which induce oxidative stress, gene mutations, and organ damage. Prolonged exposure is linked to respiratory diseases, cardiovascular disorders, immune suppression, and reproductive issues. Epidemiological studies confirm PM2.5’s carcinogenicity, with mechanisms involving DNA damage. Control strategies include source reduction and personal protection. Addressing haze requires collaborative efforts from governments, industries, and individuals to mitigate its far-reaching health consequences.
