diurnal variation of air pollutants and its impact on climate and health over the tropical semi urban city of thiruvananthapuram

Air pollution has pernicious effects on environment and human health. As a pilot study, the paper investigates the impact of air pollutants like Carbon Monoxide, Nitrogen Oxides, Sulphur Dioxide, Ozone and Particulate matters on the climate and urban health of Thiruvananthapuram, the capital city of Kerala during the period of 2017-2018, utilizing the CPCB (Central Pollution Control Board) data. The region of work falls in a relatively less polluted environment of the southern part of the Indian subcontinent (Biju, Vijayan, 2014).
The paper discusses the work in three sections:
a) Studying the diurnal variation of air pollutants’ concentration
b) Trying to establish a correlation between concentration and meteorological parameters
c) Estimating the effect of air pollution on urban health life

The study shows a positive correlation between the number of respiratory and cancer diseases and the rise of CO, NOx, O3 and Particulate matters. It is evident that Particulate matters were suspended for a long period when the convection activities were weak (December- January) and it is also established that most number of COPD (Chronic Obstructive Pulmonary Disease) and respiratory diseases were reported during this period.
