Abstract
The air pollution is majorly caused by 3 harmful pollutants viz. SO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> , NO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> and PM (Particulate Matter). Inside particulate matter, the solid particles are present mixed up with liquid droplets. The PM is of two types viz. PM10 and PM2.5. The diameter of PM10 particles is 10 mm or less, and that of PM2.5 particles is 2.5 mm or less. These particles can cause very harmful consequences on mankind. The PM particles are formed as a result of chemical reaction taking place between SO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> and NO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> . So, the knowledge of SO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> and NO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> concentrations can be a base for the prediction of PM. In this article, an effort has been put to predict PM10 component for given SO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> and NO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> pollutant concentrations using SVM (Support Vector Machine) techniques with different kernel functions in MATLAB (R2021a). The prediction performance of all prediction models is evaluated and compared.
