With a rating of 176.1 μg/m³ in January, the whole population would be at a very large risk of adverse health effects, with young children, the elderly and those with predisposition to being sick at highest risk. To give some comparison, the cleanest month recorded in Kolkata was 19.7...
To reiterate on the poor levels of air quality in Jakarta, the 2019 reading put it into 126thplace out of all the most polluted cities ranked in the world. This is a high ranking, and for some comparison, Bangkok came in at position number 737, with a PM2.5 reading of 22.8 µg/m...
In this research article, determination methods of the National Air Quality Index and the Composite Air Quality Index are discussed. The comparison between the two-indexing system reveals that the CAQI estimates more efficiently the pollutants exposure to the population as compared to the NAQI. The ...
The "PM2.5 issue" was the tipping point for China's clean air movement last year and the incentive for implementation of the new Air Quality Index (GB3095-2012). It is necessary to carry out an evaluation of the Chinese new AQI system based on comparison with developed countries and improv...

For comparison, we also include the results with a VSL that is homogeneous across regions and fixed in time at a more conservative value. Compared to an approach based on years of life lost, the use of the same VSL for all deaths may bias the valuation upwards when the population affected...
In comparison to similar studies, this work is the first detailed investigation of the impacts of COVID-19 shutdowns on the ground-level air quality in a major US city. One recently published manuscript did assess changes in PM2.5 and NO2 concentrations across the continental US (Berman and...
Beijing City Forecast Comparison. Discussion and conclusion Air pollution is an environmental problem faced worldwide, and effective AQI prediction can help in air pollution management. Traditional time series prediction models have large prediction errors in air quality prediction, which increasingly cannot...
