Evaluation on Risk Assessment on Indoor Air Pollution: A Case Study of Delhi-NCR Region

Abstract

The study is focused at delineating the major causes of air pollutants in Delhi NCR region in different aspects specifically in terms of computation of Air Quality index. The major air eight pollutants are considered for calculation of Air Quality index i.e. CO, NO., SO2, PM2.5, PM10, O3, NH3, and Pb. The prediction of air pollution is performed in two phases. The first phase computes the Air Quality Index values for all the pollutants in a day. The second phase computes threshold value of Air Quality Index as an average of previous values. The air pollution for the days in chosen month is predicted by comparing the threshold value with the average of the previous two-month values. A computer aided program is drafted and compiled on JAVA programming language of Oracle Corporation using BlueJ development environment in order to compute the Air Quality index. The program uses pollutant level values user enters and it analyses the different levels for pollutants and thereafter computes the Air Quality index level of every pollutant and tells the prominent pollutants along with its final computed value. The AQI generated can be used to analyse the level of exposures a person faces in day-to-day life and how remedies can be opted to cure the exposure towards indoor air pollution. The collected pollutants data and computed Air Quality index shows that the people in DELHI-NCR region are exposed to huge air pollution and it is relevant to the indoor air quality also.The study lessening that the air contaminations at indoor, individuals should utilise the clean energies and an improvement should be done in ovens to consume the fuel productively and vent outflows to the outside. Air cleaners that can improve the air quality productively can be helpful to cop up the scenario.
