The U.S. Environmental Protection Agency — along with partner agencies such as the National Oceanic and Atmospheric Administration and NASA — maintains an interactive map of air quality data ...
The map below displays the current air quality at monitoring sites in the U.S., Canada and Mexico. Air monitoring sites are color-coded based on the pollutant (ozone or particulate matter) with ...
Looking down from the Hollywood Hills, with Griffith Observatory on the hill in the foreground, air pollution is visible in downtown Los Angeles on a late afternoon.. Air pollution is the introduction of chemicals, particulate matter, or biological materials into the atmosphere that cause harm or discomfort to humans or other living organisms, or damage ecosystems.
Air pollution can occur naturally or be caused by human activities. [4] Air pollution causes around 7 or 8 million deaths each year. [5] [6] It is a significant risk factor for a number of pollution-related diseases, including heart disease, stroke, chronic obstructive pulmonary disease (COPD), asthma and lung cancer.
Air pollution is caused predominantly by burning fossil fuels, cars, and much more. [4] Natural sources of air pollution include forest fires, volcanic eruptions, wind erosion, pollen dispersal, evaporation of organic compounds, and natural radioactivity. These natural sources of pollution often soon disperse and thin settling near their locale.
There are over 30 active wildfires in Canada right now and some of that smoke is already creating air quality issues in Michigan and the Midwest. ... 800-290-4726 more ways to reach us. Mail. Sign ...
Good air quality, which would fall under the green level of concern, is between zero and 50. The index then slowly increases through six levels up to maroon, a hazardous air quality, with the ...
In European countries, air quality at or above 10 micrograms per cubic meter of air (μg/m 3) for PM 2.5 increases the all-causes daily mortality rate by 0.2-0.6% and the cardiopulmonary mortality rate by 6-13%. [35] Worldwide, PM 10 concentrations of 70 μg/m 3 and PM 2.5 concentrations of 35 μg/m 3 have been shown to increase long-term ...
