Get a monitor and contribute air quality data in your city. Global ranking of risk factors for death across all ages and both sexes in 1. Particulate matter, or PM, represents a category of pollution describing airborne particles measuring 10 micrograms or smaller. Particulate matter can include, but is not limited to, dust, soot, dirt, smoke, chemicals, bacteria, viruses, and liquid droplets.

Since particle pollution has a range of chemical makeups and sources, the level of risk and associated health effects are ascribed to the size of particles rather than their composition Unlike PM10, PM2. Ozone is a gaseous pollutant and key component of smog, formed when sunlight or solar ultraviolet radiation causes nitrogen oxides NOx and volatile organic compounds VOCs to react.

While other pollutants are typically emitted directly into the air by various sources, ozone is generally created in the atmosphere Show you care by giving your loved ones the gift of air purification this year.

Manmade sources, meaning that pollution is created by the actions of human beings, tend to be the leading contributor to air pollution in cities and are inherently more able to be influenced by regulations.

Manmade sources primarily include various forms of combustion, such as from gas-powered transportation planes, trains, and automobiles and industrial businesses power plants, refineries, and factoriesbiomass burning the burning of plant matter or coal for heating, cooking, and energyand agriculture. Each location has its own mix of contributors and pollutants. Sources are commonly categorized into the following:. Industry includes pollution from facilities such as manufacturing factories, mines, and oil refineries as well as coal power plants and boilers for heat and power generation.

Industrial activity is a major global source of nitrogen oxides NO xhydrogen sulfide, volatile organic compounds VOCsand particulate matter, all of which contribute to ozone and smog. The heavy use of fertilizers on agricultural land is a ificant contributor to fine-particulate air pollution. Globally, agricultural land use is on the rise due to an increased demand for animal products and per capita food.

Air pollution from transport refers primarily to fuel combustion in motor vehicles, such as in cars, trucks, trains, planes, and ships. Transport emissions are a major contributor to elevated levels of fine particulate matter PM2. As standards of living and economic activity increases, so too does the demand for transportation.

Natural air pollution sources include naturally occurring phenomena such as volcanic activity, wildfires, and dust or sandstorms. The impact of natural sources on air quality is highly dependent on the local environment. For example, locations near large deserts like the Sahara are greatly impacted by windblown dust and sand, while forested locations are more likely to experience air pollution from wildfires. Household air pollution refers to personal activities, such as residential cooking and heating with coal or wood burning as well as the building and construction of homes and furnishings.

The burning of plant matter emits large amounts of pollutants, as does burning other solid fuels like coal. These fires may occur organically, accidentally, or intentionally.

Due to the frequently massive size of these fires, both wildfires and open burning have the potential to cause far-reaching air pollution. At ificant levels, all types of air pollution pose a risk for adverse health effects. The World Health Organization WHO has deemed air pollution as the greatest environmental health risk today, estimated to contribute to 7 million premature deaths annually.

While this figure varies region to region, nowhere is without risk. The World Air Quality Report found that Masks are very effective in reducing exposure to air pollution. While the broad category of air pollution masks includes gas masks for dealing with highly toxic chemicals, the majority of ambient air pollution masks on the market only filter particle pollution. For daily use, these masks are generally sufficient because outdoor environments rarely experience gases at the same dangerous levels as particles. Ambient air pollution masks can help protect an individual from PM2. In evaluating the effectiveness of pollution masks, three components should be evaluated: pollution filter, mask seal, and ventilation.

Disposable surgical masks are affordable and accessible.

They are also surprisingly effective against particle pollution. An Edinburgh study conducted by the Particle and Fiber Toxicology tested surgical masks down to. In another study, a fit test was applied to surgical masks in order to more accurately test their effectiveness, noting the generally loose fit.

While both tests reveal that surgical masks are ificantly less efficient than respirator masks rated NNthey do help reduce exposure to fine particulate pollution at a very low cost. The most prevalent and commonly discussed type of pollution mask is the N This is because the rating only states the required minimum filtration and not the precise filtration rate.

Indoor air quality is not safe from outdoor air pollution. Moreover, there are numerous emission sources specific to indoor environments that can lead to heightened indoor air pollution levels. In order to improve air quality at home, both indoor ventilation and indoor sources should be managed. ificant atmospheric aerosol pollution caused by world food cultivation.

Impact of breathing unhealthy air - overview: The World Health Organization WHO has deemed air pollution as the greatest environmental health risk today, estimated to contribute to 7 million premature deaths annually. High air pollution levels can cause health problems including: Short-term effects: difficulty breathing, chest pain, wheezing, coughing, general respiratory discomfort, and irritation of the eye, nose, and throat. Long-term effects: lung tissue damage, cancer, early death, and the development of respiratory illnesses such as asthma, bronchitis, and emphysema.

Groups most susceptible to severe adverse health effects from air pollution include those with: Heart disease, such as coronary artery disease CAD or congestive heart failure Lung disease, such as asthma, emphysema, or chronic obstructive pulmonary disease COPD Older adults and the elderly Children under the age of 14 Pregnant women Outdoor workers Athletes who exercise outdoors vigorously Health effects from specific air pollutants Ground-level Ozone Particulate Matter PM and Wildfire Smoke Short-term Long-term Reduced lung function Aggravated asthma Throat irritation and cough Chest pain and shortness of breath Inflammation of lung tissue Higher susceptibility to respiratory infection Irregular heartbeats Chest pain Coughing Irritation of the eye, nose, and throat Aggravated asthma Decreased lung function Lung tissue damage Cancer Development of respiratory illnesses such as asthma, bronchitis, and emphysema Early death.

Protect from air pollution Which mask is best for air pollution? This includes the vast majority of PM2. The higher the rating, the more effective the mask filter, assuming the mask seal and ventilation components work properly. A good mask seal should cause the mask to suction to one's face during inhalation.
