What factors affect air quality?

When studying air quality, it is important to measure the following factors as they can help us understand the chemical reactions that occur in the atmosphere:

  • wind speed and direction.
  • temperature.
  • humidity.
  • rainfall.
  • solar radiation.

What impacts has the Clean Air Act had?

Today, as in the past, the Clean Air Act continues to cut pollution and protect the health of American families and workers. Fewer premature deaths and illnesses means Americans experience longer lives, better quality of life, lower medical expenses, fewer school absences, and better worker productivity.

Is carbon dioxide a primary or secondary pollutant?

Carbon Monoxide (CO) Carbon monoxide is released from volcanoes and forest fires as well. Secondary pollutants like ozone and carbon dioxide (CO2), a greenhouse gas, come from carbon monoxide.

Is nitrogen dioxide regulated by the EPA?

The Clean Air Act requires EPA to set national ambient air quality standards (NAAQS) for nitrogen oxides and five other pollutants considered harmful to public health and the environment (the other pollutants are ozone, particulate matter, carbon monoxide, sulfur dioxide, and lead).

What federal laws control greenhouse gas emissions?

Regulatory Authority According to the rule, the EPA is authorized to regulate greenhouse gas emissions under Section 111 of the Clean Air Act. This section requires EPA to develop regulations for categories of sources that cause or significantly contribute to air pollution that may endanger public health or welfare.

Why should we reduce greenhouse gas emissions?

With great power comes great responsibility – and our ability to harness natural gases for means of production and development is no different. Reducing this flow and emission of the greenhouse gases that spur global warming could prevent up to 3 million premature deaths annually by the year 2100.
