Different methods have been designed to calculate the air quality index in form of mathematical formula. But the formula designed by Central Pollution Control Board in 2014 is more robust to find out the air quality category. The index has been calculated based upon four parameters like particulate matters (PM10, PM2.5), sulfur oxide and nitrogen oxide. The study area has affected by different ...
a four year long research programme divided into four phases has been designed for the first time to assess the combined noise-air quality and combined exposure to noise-air pollution at the curbside open-air microenvironment of kolkata city, india. the results and the findings of the different phases of study had already been published. the objective of the review work is to fuse the findings ...
The boiler is one of the most vulnerable parts of a power plant, which is responsible for producing steam for moving turbines. In order to increase the thermal efficiency of the power plant, it is necessary to prevent heat loss in the boiler combustion chamber and simultaneously control the environmental pollutant parameters such as NOx and CO. Failure to control environmental pollutants will...
Air pollution caused due to the introduction of particulate matters, biological molecules and other harmful materials into the Earth's atmosphere. Pollution brings vital diseases, death to humans, damages other living organisms such as vegetations, animals, natural environment and built environment. Data mining concerned with finding hidden patterns inside largely available data, so that the in...
Background: The undesirable condition of air quality is one of the most important environmental problems that have challenged many of the world's cities. In this study, considering the importance of particle matter as one of the most important atmospheric pollutants in Ahwaz, the main objective is the air quality assessment of this city in terms of PM2.5 and PM10 in 2016-2017. Methods: The air ...
Introduction and Purpose: Nowadays, the air quality in many major cities is one of the most important environmental problems that seriously compromises the health of residents and causes a range of acute and chronic health effects. herefore, this study was aimed to quantify and estimate the health effects related to the pollutants NO2 and O3 in metropolis of Tehran in 2014 was done ...
Background and Aim: A ssociations between air pollution and morbidity have been reported in several studies. Due to limited publications in the literature for Iran, this study aimed to determine the association between air pollution and hospital admissions of respiratory disease patients in Tabriz, Iran. Materials and Methods: The methodology used in this study was case -crossover and the a...
In this paper, we develop an integrated cost-benefit analysis framework for ozone and fine particulate control, accounting for variability and uncertainty. The framework includes air quality simulation, sensitivity analysis, stochastic multi-objective air quality management, and stochastic cost-benefit analysis. This paper has two major contributions. The first is the development of stochastic ...
Background: Air pollution is one of the most important factors threatening the health of citizens. It increases the prevalence of cardiovascular and respiratory diseases as well as emergency admissions to hospitals in the polluted metropolitan cities. The present study was conducted using Air Quality (AirQ) model and aimed to investigate the effects of air pollution on the n...
