MONITORING AMBIENT AIR QUALITY STUDY IN ARIYALUR, TAMILNADU, INDIA

Abstract

Particulate matter is a major air contaminant in the ambient air and wide information is assessable on its concentrations from various parts of the world. Air pollutants with the strongest evidence for public health concern, include particulate matter (PM), ozone (O₃), nitrogen dioxide (NO₂) and sulphur dioxide (SO₂).  Air pollutants are reported to be harmful to human health if their concentrations exceed certain acceptable levels. Industries have contributed substantially to the air pollution problem as point source of emissions. Understanding the current status of ambient air quality in and around Peenya in Bangalore will help to identify the probable sources of pollutants to facilitate the effective control measures. The aim of the present work is to determine the ambient air quality of Peenya region in terms of PM₁₀, PM₁₀₀, PM_2.5, SO₂, NO_x and CO levels to identify the probable sources of pollutants to facilitate the effective control measures. As Ariyalur is a land of limestone, the cement industries flourishes to maximum resulting in air pollution. The present study was concerned with the determination of particulate matter concentration at different locations of Ariyalur. The experiments were carried out from January to December 2020. Thus, it was clear that the values are higher than the prescribed standards and it is impartment that the control measures must be taken to check the air pollution.
