Evaluation of SO2 Concentration in Industrial Area and Urban Area in Klang Valley

Abstract

Air pollution shows some health and environmental challenges especially in rapidly urbanising and industrialising areas like Klang Valley. Sulfur dioxide, SO₂ especially produced through fossil fuel combustion in vehicles and industrial activities is a key pollutant of concern due to its harmful effects on human health and air quality. This study aims to evaluate and compare the SO₂ concentrations between an industrial area in Petaling Jaya and an urban area in Putrajaya throughout year 2023.
