Air pollution can cause a variety of illnesses in humans, including asthma, lung cancer, heart disease and even reproductive and developmental disorders. It can also compromise the immune system by overworking the respiratory system and the body's natural defenses. Air pollution also contributes to global warming, increasing worldwide temperatures, raising sea levels and damaging agricultural yields.Know More
According to the World Health Organization, air pollution accounts for as many as seven million premature deaths worldwide each year. This includes not only outdoor air pollution from vehicles, industrial sources and power generation, but also indoor air pollution from burning fuel for cooking or heat. Most of these deaths occur in the developing world, in countries where environmental regulations are less strict and the populations lack access to cleaner energy options.
Another way in which air pollution can be dangerous is when it contains particulates and volatile organic compounds. These particles can represent threats in many different ways, ranging from chemical effects on the body to low-level radiation, depending on the source. Breathing in these particles in smog can pose a significant health risk even beyond a respiratory problem. The nitric oxide and sulfur dioxide created when fossil fuels combust can also contribute to smog and acid rain.Learn more about Pollution
In the United States, the amount of air pollutants in the atmosphere can be directly measured by anyone using instruments such as the GASPer air quality monitor, area's immediate reading, or AIR device and sun photometer. Common examples of air pollution include smog, vehicular and power plant emissions and acid rain.Full Answer >
Air pollution has several harmful effects on both the environment and human health. A common example of the negative effects of air pollution on the environment is in the form of acid rain. Many upper respiratory diseases such as asthma are exacerbated by air pollution.Full Answer >
Air pollution stems from the addition of unnatural compounds and toxins through indirect and direct mechanisms. Direct sources of air pollution include electricity, fuels and transportation, while indirect sources are goods and services that require energy to produce and deliver, such as vehicles and household appliances.Full Answer >
The leading cause of air pollution is the burning of fossil fuels, but other pollutants, such as pollen, smoke from fires and the gases given off from organisms while they are decaying, also contribute. Air pollution is caused by both human activities and naturally occurring events.Full Answer >
