INFLUENCE OF HUMIDITY AND TEMPERATURE ON PARTICULATE MATTER (PM2.5 AND PM10) IN TRIVANDRUM CITY, INDIA: A TEMPORAL ANALYSIS

Abstract
Air quality in urban areas has become a growing global concern due to the detrimental effects of Particulate Matter (PM2.5 and PM10) on public health. These fine particles are associated with a range of adverse health outcomes, including respiratory diseases, cardiovascular conditions, and an increased risk of premature mortality. As urbanization accelerates, especially in developing regions, cities like Trivandrum, the capital of Kerala, India, are witnessing significant increases in vehicular emissions and industrial activities, which contribute to the escalating levels of air pollution. Tropical climate of Trivandrum, characterized by high humidity, moderate temperatures, and seasonal variations, presents a unique set of challenges for air quality management, making it essential to explore the specific relationship between meteorological factors and particulate matter concentrations. The central objective of this study is to investigate how temperature and relative humidity influence the levels of particulate matter (PM2.5 and PM10) in Trivandrum City over the course of a full calendar year, from January 1, 2023, to December 31, 2023. Meteorological factors such as temperature and humidity play a critical role in determining the dispersion, accumulation, and removal of these airborne particles. In this study, data from the Central Pollution Control Board (CPCB) of India were analysed to examine how seasonal variations in temperature and humidity correlate with fluctuations in particulate matter concentrations. By exploring these relationships, this study aims to provide valuable insights into the dynamics of particulate pollution in Trivandrum City, thereby contributing to the development of effective air quality management strategies, particularly in regions with tropical climates that experience seasonal shifts. Understanding these meteorological influences is crucial for mitigating the health impacts of air pollution and improving the overall quality of life for urban residents.
