One strategy for improving air quality in key areas of a city within the UK, is to implement a Clean Air Zone (CAZ). A CAZ is a designated part of a city, where polluting vehicles are charged a fee to drive through, while low-emission vehicles meeting certain criteria can continue to ...
The Indian Government and the US-EPA both use PM10 and PM2.5 as one of the criteria for air quality index (AQI) calculation. The safe exposure levels for PM10 (24 hours) are 0-100 ug/m3 and for PM 2.5 (24 hours) is 0-60 ug/m3 as per the Indian CPCB. As per US-EPA, safe ...
The air quality criteria are stricter than the limit values in the regulations. The City Council aims to keep local emissions of airborne dust well below the health authorities' recommendations. A spokesperson from the Urban Environment Agency reported that the measurements show that the annual averag...
In this chapter, a discussion is made based on the data on criteria pollutants and air quality index (AQI) for selected sites in New Delhi and for selected cities across the country, respectively to spell out impacts of COVID-19 (which are initially positive) and the lessons for long-term...
Najafpour AA, Janeidi Jafari A, Doosti S. Trend analysis of Air Quality Index criteria pollutants (CO, NO2, SO2, PM10 and O3) concentration changes in Tehran metropolis and its relationship with meteorologi- cal data, 2001-2009. J Health Field. 2015;3(2):17-26....
A literature review shows that to date few studies have reported high-resolution predicted surfaces for all criteria pollutants and total air quality index (AQI, for the quantification definition, refer to Supplementary Note 4). This study fills this gap and provides a fine-scale grid of AQI ...

As the multi-criteria decision-making problem, Ma et al. pointed out that the final choice of the decision-maker may be adjusted and changed with the importance of evidence22. It can be analyzed that weights of evaluation factors are key to the final fusion results. Fei et al. determined ...
A lead in one direction is taken by green building rating systems, which have started to include the criteria for IEQ and insist on real time monitoring (Licina et al., 2021). This initiative could be seen as an attempt to resolve the conflict between energy conservation and good IAQ. To...
Random forest prediction of future air quality The empirical results show that the predicted values of both the SARIMA model and the RF model effectively match the trend associated with actual values, and achieve an effective benchmark for scale prediction. Model accuracy evaluation criteria were used...
