However, this improvement was transitory, and it reverted in the post-COVID era. Therefore, policies should be formulated and practiced to improve air quality in the long term.doi:10.4209/aaqr.220053Khan, SolaimanUniv MissouriDahu, Butros M....
I should mention here that the fresh air flow rate is representative of the improvement to the air quality in the classroom. We kept the room temperature constant during the tests so that this did not influence the results in any way. Our studies were carried out in rural areas, so the ...

this deterioration was not observed in most of the other stations, with double-track tunnel stations showing averagely similar values with and without forced ventilation (Table 1), with Artigues, Verneda, La Pau and, to a minor extent, Paral-lel, having actually an improvement in PM levels un...
Effects of Air Pollution Finding ways to reduce air pollution can have positive impacts on the world as a whole and on our own health. If we can improve air quality, we can lower respiratory and cardiovascular diseases because even short-term exposure to air pollutants cancause health problems...
With carbon tax of climate policy, regions with fewer trucks could gain in health benefits, while regions with added rail freight may potentially cut their local air quality improvement in terms of PM2.5 pollution. The climate policy scenario assumes that a 450 ppm CO2 concentration will be ...

We found that city lockdowns led to a sizeable improvement in air quality. Within weeks, the AQI in the locked-down cities was brought down by 19.84 points (PM2.5 down by 14.07 µg m−3) relative to the control group. In addition, air quality in cities without formal lock...
Energy efficiency improvement is often hindered by the energy efficiency gap. This paper examines the effect of short-run temperature fluctuations on the Energy Star air conditioner purchases in the United States from 2006 to 2019 using transaction-level data. Results show that the probability of pur...
