Air pollution is the contamination of air due to the presence of substances called pollutants in the atmosphere that are harmful to the health of humans and other living beings, or cause damage to the climate or to materials. [1] It is also the contamination of the indoor or outdoor environment either by chemical, physical, or biological agents ...
Pollution is the introduction of contaminants into the natural environment that cause adverse change. [1] Pollution can take the form of any substance (solid, liquid, or gas) or energy (such as radioactivity, heat, sound, or light). Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring ...
Health effects. Due to air pollution causing more than one effect it is hard to attribute a condition only to air pollution or to say how much a given source is responsible. However, it is believed that around 100,000 to 200,000 human deaths are attributable to air pollution and at least a quarter are due to transportation.
Reaction with daylight ultraviolet (UV) rays and these precursors create ground-level ozone pollution (tropospheric ozone). Ozone is known to have the following health effects at concentrations common in urban air: Irritation of the respiratory system, causing coughing, throat irritation, and/or an uncomfortable sensation in the chest.
The replacement of coal-based energy with renewables can lower the number of premature deaths caused by air pollution and decrease health costs associated with coal-related respiratory diseases. This switch to renewable energy is crucial, as air pollution is responsible for over 13 million deaths annually.
Air pollution is associated with adverse health effects like respiratory and cardiovascular diseases, cancer, related illnesses, and even death. The risk of air pollution is determined by the pollutant's hazard and the amount of exposure that affects a person.
Health effects (or health impacts) are changes in health resulting from exposure to a source. Health effects are an important consideration in many areas, such as hygiene, pollution studies, occupational safety and health, ( [nutrition]) and health sciences in general. Some of the major environmental sources of health effects are air pollution ...
The quality of air is considered satisfactory and the air pollution poses minimal or no health risks. Fair — when the index is between 51 and 100 imecas. The quality of air is acceptable, however some contaminants could have moderate health effects for a small fraction of the population that has high sensitivity to some contaminants.
