How does the UK’s air quality compare to other countries? In international comparison, the UK in 2019 was ranked 21st out of global countries with the lowest levels of PM2.5 nationally on IQAir’s World’s Most Polluted Countries 2019 report, with an annual average concentration of 10.5 ...
The average annual figure was US AQI 40, in comparison to Bangladesh which was the most polluted country with a US AQI figure of 162. The cleanest city was Waimea, Hawaii with a figure of just 9, whereas the most polluted city was Yosemite Lakes, California with a figure of 107. Is ...
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...
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...
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 ...
While the primary policy scenario results in a widening of the air pollution exposure disparity for racial/ethnic minorities, further reductions in racial/ethnic minority exposures are in principle achievable while still meeting the same CO2emissions reductions. The comparison between the Cap 50% scenari...
continued such as from cooking activities; external sources outside of the city’s boundaries [38] apart from dust from roads [42] are both likely to have been a major cause of the reduced pollution. Both cities have relatively less motorised vehicles in comparison to the other cities....

The correction of MODIS C5.1 data using a fit to AERONET FMF works well, as shown by comparison with PARASOL data for the overlapping period [94]. This correction was used in the PMRS model [90] together with an improvement to the hygroscopic growth factor. The PM2.5 calculated using the...
To evaluate the potential of these emission reductions on AQ in comparison to the previous years, we compared the sig ΔΔ related to the pandemic to the detrended IAV of the base period. We calculated the effectiveness of the reduction in traffic volume (ETR) to reduce air pollutants during...
