There are six common air pollutants which threaten our health and environment. These are classified as ozone, particulate matter, carbon monoxide, nitrogen dioxide, sulfur dioxide, and lead. The Environmental P
Combustion of fossil fuel at various sources results in the discharge of such pollutants as carbon dioxide (CO2), carbon monoxide (CO), unburnt hydrocarbon (HC), nitrogen oxides (NOX), sulfur dioxide (SO2), lead (Pb), particulate matter (PM), which in turn reduce urban air quality and ...
The interaction between green infrastructure design (e.g., species selection, spatial positioning) and air pollutants can positively or negatively affect personal exposure and thus human health (Abhijith et al., 2017). The effects depend on the conditions of the surrounding built environment, as ...
In addition to the large amount of primary pollutants, in large quantities, the primary polluting gases can become precursors to secondary pollutants6. The deterioration in air quality is also accompanied by physical processes, such as flowing, aggregation, and crushing of large amounts of fine ...
(2–3 rings) weight groups17,18,19. PAHs are generally classified as relatively persistent organic and environmental pollutants20,21,22. Higher molecular weight PAHs groups are relatively immovable, and moderately insoluble in water18,23. PAHs are normally found in the bottom sediments, thus ...
Pollutant emissions and their contribution to local and regional air quality at the industrial area of Tula were studied during a four-week period as part of the MILAGRO initiative. A recurrent shallow stable layer was observed in the morning favoring air pollutants accumulation in the lower 100...
As a major substance in air pollutants, PM2.5 is closely related to human health[7,8]. Many studies have been carried out on respiratory damage caused by PM2.5[9]. Lung cancer is a malignant tumor that threatens human life and health. In recent years, the incidence and mortality of lung...
air is trapped near the ground under a layer of warm air. This condition suppresses the normal tendency of pollutants to rise and disperse over a wide area, trapping them instead in a relatively shallow boundary layer and causing winter haze to be optically thick (as often seen in satellite ...
One of the most sectors that must be taken into consideration through pandemic coronavirus (COVID-19) around the globe is the air conditioning systems. The HVAC systems depend on the air as a heat transfer medium. The air contains a group of pollutants, viruses, and bacteria, and it ...
The EKC hypothesis linked economic development to environmental quality in such a paradigm: per capita income and per capita carbon dioxide emissions increase together until a certain inflection point in income is reached, after which the growth of pollutants levels off and then overturns (Grossman ...
