Air Pollution Resistant Plants Along Highways in Jaunpur Region

Abstract

In emerging areas like Jaunpur, Uttar Pradesh, air pollution from vehicle emissions is a serious environmental concern. Particulate matter (PM), nitrogen oxides (NOx), sulfur dioxide (SO₂), and carbon monoxide (CO) are among the major pollutants found on highways. By serving as organic biofilters, roadside vegetation is essential for reducing air pollution. This study uses the Air Pollution Tolerance Index (APTI) to identify plant species that are resistant to air pollution beside highways in the Jaunpur region. Important plant species were examined, including Polyalthia longifolia, Ficus religiosa, and Azadirachta indica. The findings show that because of physiological and biochemical changes, some species have greater tolerance. According to the study's findings, planting tolerant plants can greatly enhance environmental sustainability and air quality
