HydroR Plugin Electric Vehicle addresses many urban areas exposure to air pollution in the main environmental threat to human health and long term exposure to high levels of soot and small particles in the air contributes to a wide range of health effects including heart disease lung cancer and respiratory diseases. Particulate pollution in combination with sulfur diEmissions of sulfur dioxide and nitrogen oxides
lead to the deposition of acid rain and other acidic
compounds over long distances. Acid deposition
changes the chemical balance of soils and can lead
to the leaching of trace minerals and nutrients critical
to trees and plants.
Where coal is the primary fuel for power plants,
steel mills, industrial boilers, and domestic heating,
the result is usually high levels of urban air
especially particulates and sometimes
sulfur dioxide—
and, if the sulfur content of the coal
is high, widespread acid deposition. Where coal is
not an important primary fuel or is used in plants
with effective dust control, the worst emissions of air
pollutants stem from the combustion of petroleum
The data on sulfur dioxide and nitrogen dioxide concentrations
are based on reports from urban monitoring
sites. Annual means (measured in micrograms per
cubic meter) are average concentrations observed at
these sites. Coverage is not comprehensive because
not all cities have monitoring systems.
The data on concentrations of particulate matter
are estimates, for selected cities, of average annual
concentrations in residential areas away from air pollution
“hotspots,” such as industrial districts and
transport corridors. The data are extracted from a
complete set of estimates by the World Bank’s Development
Research Group and Environment Department
in a study of annual ambient concentrations
of particulate matter in world cities with populations
exceeding 100,000 (Pandey and others 2006).
Pollutant concentrations are sensitive to local conditions,
and even in the same city different monitoring
sites may register different concentrations.
Thus these data should be considered only a general
indication of air quality in each city, and cross-country
comparisons should be made with caution. The
current World Health Organization (WHO) air quality
guidelines are annual mean concentrations of 20
micrograms per cubic meter for particulate matter
less than 10 microns in diameter (PM10) and 40
micrograms for nitrogen dioxide and daily mean concentrations
of 20 micrograms per cubic meter for
sulfur dioxide.
