Public health concerns related to high air pollution exposures include cancer, cardiovascular disease, respiratory diseases, diabetes mellitus, obesity, and reproductive, neurological, and immune system disorders. Research on air pollution and health effects continually advances.
Numerous scientific studies have linked air pollution to a variety of health problems (Table 6.2) including: aggravation of respiratory and cardiovascular diseases; decreased lung function; increased frequency and severity of respiratory symptoms such as difficulty breathing and coughing; increased susceptibility to respiratory infections; effec...
Air pollution affects all things. It is harmful to our health, and it impacts the environment by reducing visibility and blocking sunlight, causing acid rain, and harming forests, wildlife, and agriculture. Greenhouse gas pollution, the cause of climate change, affects the entire planet.
The World Health Organization (WHO) reports on six major air pollutants, namely particle pollution, ground-level ozone, carbon monoxide, sulfur oxides, nitrogen oxides, and lead. Air pollution can have a disastrous effect on all components of the environment, including groundwater, soil, and air.
The guidelines provide evidence of the damage air pollution inflicts on human health, at even lower concentrations than previously understood. The updated guidelines provide recommendations on air quality guideline levels as well as interim targets for six key air pollutants.
Learn about what causes air pollution and how to help reduce the effects. How smog, soot, greenhouse gases, and other top air pollutants are affecting the planet—and your health.
In 2019, air pollution caused about 6.7 million deaths. Of these, almost 85% are attributable to noncommunicable diseases (NCDs), including ischemic heart disease, stroke, lung cancer, asthma, chronic obstructive pulmonary disease (COPD), and diabetes.
Almost every organ in the body can be impacted by air pollution. Due to their small size, some air pollutants are able to penetrate into the bloodstream via the lungs and circulate throughout the entire body leading to systemic inflammation and carcinogenicity.
Effects on Humans. People experience a wide range of health effects from being exposed to air pollution. These effects can be broken down into short-term effects and long-term effects. Short-term effects, which may be temporary, include illnesses such as pneumonia or bronchitis.
Air pollution – the combination of outdoor and indoor particulate matter and ozone – is a risk factor for many of the leading causes of death, including heart disease, stroke, lower respiratory infections, lung cancer, diabetes, and chronic obstructive pulmonary disease (COPD).
