You should be more aware after reading one of these following facts about air pollution below since it will explain to you how dangerous pollution is. Air pollution is the introduction of particulates, biological molecules, or other harmful materials into the Earth’s atmosphere, possibly causing disease, death to humans, damage to other living organisms such as food crops, or the natural or built environment. Furthermore, to get to know more about this, here are some other facts about air pollution you might consider helpful for your environment.
Facts about air pollution 1: Atmosphere
The atmosphere is a complex natural gaseous system that is essential to support life on planet Earth, Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earth’s ecosystems.
Facts about air pollution 2: World’s Toxic Pollution
Indoor air pollution and urban air quality are listed as two of the world’s worst toxic pollution problems in the 2008 Blacksmith Institute World’s Worst Polluted Places report.According to the 2014 WHO report, in 2012 the air pollution caused the deaths of around 7 million people worldwide.
Facts about air pollution 3: Air Pollutant
An air pollutant is a substance in the air that can have adverse effects on humans and the ecosystem. The substance can be solid particles, liquid droplets, or gases. A pollutant can be of natural origin or man-made. Pollutants are classified as primary or secondary.
Facts about air pollution 4: Emission Factors
Air pollutant emission factors are representative values that people attempt to relate the quantity of a pollutant released to the ambient air with an activity associated with the release of that pollutant. These factors are usually expressed as the weight of pollutant divided by a unit weight, volume, distance, or duration of the activity emitting the pollutant.
Facts about air pollution 5: Air Pollution Exposure
Air pollution risk is a function of the hazard of the pollutant and the exposure to that pollutant. Air pollution exposure can be expressed for an individual, for certain groups (e.g. neighborhoods or children living in a county), or for entire populations. For example, one may want to calculate the exposure to a hazardous air pollutant for a geographic area, which includes the various micro-environments and age groups.
Facts about air pollution 6: Health Effects
Air pollution is a significant risk factor for a number of health conditions including respiratory infections, heart disease, COPD, stroke and lung cancer.The health effects caused by air pollution may include difficulty in breathing, wheezing, coughing, asthma and worsening of existing respiratory and cardiac conditions.
Facts about air pollution 7: History
The worst short-term civilian pollution crisis in India was the 1984 Bhopia Disaster. Leaked industrial vapours from the Union Carbide factory, belonging to Union Carbide, Inc., U.S.A. (later bought over by Dow Chemical Company), killed more than 25,000 people outright and injured anywhere from 150,000 to 600,000.
Facts about air pollution 8: Cities
Air pollution is usually concentrated in densely populated metropolitan areas, especially in developing countries where environmental regulations are relatively lax or nonexistent.
Facts about air pollution 9: Hotspots
Air pollution hotspots are areas where air pollution emissions expose individuals to increased negative health effects. They are particularly common in highly populated, urban areas, where there may a combination of stationary sources (e.g. industrial facilities) and mobile sources (e.g. cars and trucks) of pollution.
Facts about air pollution 10: Regulations
In general, there are two types of air quality standards. The first class of standards (such as the U.S. National Ambient Air Quality Standards and E.U. Air Quality Directive set maximum atmospheric concentrations for specific pollutants. Environmental agencies enact regulations which are intended to result in attainment of these target levels.
