Development of a Fuzzy Pattern Recognition Model for Air Quality Assessment of Howrah City

Abstract

The district of Howrah is one of the most highly industrialized districts in West Bengal, India. Howrah City continues to suffer from poor ambient air quality due to the dense siting of small scale industries without air pollution management, huge traffic congestion and high levels of human settlement. This paper presents the trends of air pollution concentration (O 3 , CO, SO 2 , NO 2 , and PM 10 ) in Howrah City, and also demonstrates a new methodology for air quality assessment using an AHP coupled fuzzy pattern recognition model. . There was no uniform trend observed in the annual the eighthour average concentration of ozone. An approach was developed in this study to determine fuzzy air quality based on the observed air pollution concentration. This will help to identify the air pollution control measures that are required in a certain area. The proposed method is a multi-pollutant aggregation method with varying weighting, and has the capability to consider subjective factors like sensitivity and population density. The concentrations of the five air pollutant parameters (O 3 , CO, SO 2 , NO 2 , and PM 10 ) were used to develop the model for air quality assessment.

Predicting Common Air Quality Index - The Case of Czech Microregions

“…For the AQIs it holds true that the limit value is met if AQIAP t < 1. A similar approach was used by van den Elshout et al (2008) for the common AQI in Europe. This AQI emphasizes the role of traffic as a source of pollution, as it uses AQIs for city background and traffic situations.…”

“…Air quality indices (AQIs) (Kassomenos et al, 1999;Murena, 2004;Upadhyay et al, 2014) were initially established in response to health issues related to the deteriorating air quality. AQIs are used to report on the state of air pollutants (APs), which are widely accepted as important determinants of adverse health effects.…”

A Fuzzy Expression Way for Air Quality Index with More Comprehensive Information

“…Clearly, it is fairly unreasonable to assign the same weight to each air pollutant subjectively; since different air pollutants have varying health impacts and hence the corresponding weights of air pollutants are different in the determination of the overall AQI. For the sake of determining the weights of various pollutants, the AHP was applied into subsequent research by Mandal et al [22], Khan and Sadiq [30] and Upadhyay et al [31]. Meanwhile, other substitutable methods, such as expert scoring, fuzzy synthetic evaluation, and so on, can also be used to ascertain the weights of different pollutants.…”

Assessing the Immediate Impact of COVID-19 Lockdown on the Air Quality of Kolkata and Howrah, West Bengal, India

“…rapid urbanization, higher population growth, increased energy consumption, and vehicular emission and industrial emission (Dadhich et al 2018;Ghose et al 2005;Gupta et al 2008). Kolkata is the most polluted metropolis in India and suffers from the highest pollution levels among eight tropical Asian countries on the other hand Howrah is considered as one of the highly industrialized district in West (Mukherjee et al 1998;Upadhyay et al 2014;Financial Express 2020), This study aims to evaluate the changes in air quality in terms of pollutant concentration during the implementation of the lockdown measures considering COVID-19 pandemic in Kolkata and Howrah, the twin cities of West Bengal.…”
