Not all countries have adopted air quality regulations as america has. what impact on human health would these countries experience if they adopt air quality regulations similar to the americas? a) the amount of exposure to outdoor and indoor air pollution would remain unchanged. b) the number of premature deaths related to ultrafine particulate exposure would increase. c) people would experience a decrease in negative health effects associated with air pollution. d)effects from impaired breathing would only decrease for those exposed to outdoor air pollution.

c. People would experience a decrease in negative health effects associated with air pollution.

In 1970, the Environment protection agency (EPA) proposed the Clean Air Act applicable in US. The act has been amended many times to keep pace with new information. Under this act EPA has established standard limits for six air pollutants such as carbon monoxide (CO), lead (pb), nitrogen dioxide(NO₂), sulfur dioxide(SO₂), ozone (O₃) and particulate matter.  The clean air act has established two quality standards:

1. Protection of public health, involving prevention of population from asthma and other respiratory diseases.

2. Protection against damage to animals, crops, plants and buildings.

The countries which will adopt air quality regulations similar to America will get better regulation of air quality by controlling the level of pollutants present in the air. Hence, people would experience a decrease in negative health effects associated with air pollution.
