Air pollution is the largest environmental risk factor for disease and premature death [5] [14] and the fourth largest risk factor overall for human health. [15] Air pollution causes the premature deaths of around 7 million people worldwide each year, [5] or a global mean loss of life expectancy (LLE) of 2.9 years, [16] and there has been no ...
The U.S. also saw an uptick in air pollution, climbing from a nationwide average of 8.9 µg/m3 in 2022 to 9.1 in 2023, with the southward-drifting smoke from Canada’s wildfires partly to blame.
Air pollution can be a high risk for certain groups, including children under 18, adults over 65, people with chronic heart or lung disease, pregnant women and people with diabetes, according to ...
Since the EPA first started regulating clean air in the 1970s, emissions of the most common air pollutants have dropped by almost 80%. But around Houston, there's still a long way to go.
Diseases caused by pollution, lead to the chronic illness and deaths of about 8.4 million people each year. However, pollution receives a fraction of the interest from the global community. [1] This is in part because pollution causes so many diseases that it is often difficult to draw a straight line between cause and effect.
This creates air pollution, including nitrous oxides and particulates, and is a significant contributor to global warming through emission of carbon dioxide, [275] for which transport is the fastest-growing emission sector. [276] By subsector, road transport is the largest contributor to global warming. [275]
The index aims to help the public easily understand the air quality and protect people's health. The CAI is on a scale from 0 to 500, which is divided into six categories. The higher the CAI value, the greater the level of air pollution. Of values of the five air pollutants, the highest is the CAI value.
Air pollution is bad for our heart and lung health – and a new study says it may be bad for brain health, too.
