Schematic drawing, causes and effects of air pollution: (1) greenhouse effect, (2) particulate contamination, (3) increased UV radiation, (4) acid rain, (5) increased ground-level ozone concentration, (6) increased levels of nitrogen oxides. An air pollutant is a material in the air that can have many effects on humans and the ecosystem. [64]
Ozone from air with high oxygen level, catalysed by nitrogen oxides; Soot and particulate from exhausts and industry; Greenhouse effect by keeping sun warmth and light from reflecting back into space; Particulate contamination affecting respiratory systems; Raised UV radiation levels by destruction of the ozone layer;

TEMPO will measure pollutants such as “ozone, nitrogen dioxide, formaldehyde, aerosols, water vapor, and several trace gases,” according to NASA.
Soon after the EPA's founding, the agency dispatched 100 photographers to capture America's environmental problems in a photo project called Documerica.
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.
However, there is no known safe level of exposure and thus, any exposure to particulate pollution is likely to increase an individual's risk of adverse health effects. [35] 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 ...
Various definitions of pollution exist, which may or may not recognize certain types, such as noise pollution or greenhouse gases.The United States Environmental Protection Administration defines pollution as "Any substances in water, soil, or air that degrade the natural quality of the environment, offend the senses of sight, taste, or smell, or cause a health hazard.
