Air pollution levels have reached unsafe levels, threatening human health in various regions of the world. According to The Washington Post, this is evidenced by the results of a study published in the journal Nature.
More than 80 percent of the world’s urban population has been found to experience pollution levels that exceed safe limits set by the World Health Organization. Among the most polluted regions of the world are China, India and the United States.
In China, despite the widespread implementation of measures to combat air pollution, air quality in some cities still leaves much to be desired. In India, the situation is even more critical, especially in the Delhi metropolitan area, where air pollution levels often reach unprecedented levels, leading to serious health problems. In the US, the problem of air pollution also remains relevant, especially in large cities such as Los Angeles and New York.
The study also found that even short-term exposure to polluted air can lead to serious health effects such as asthma and other respiratory illnesses. Some scientists have also linked air pollution to heart disease and even certain types of cancer.
One of the main sources of air pollution is road transport, especially in cities with high population density. Industry, the extraction and combustion of fossil fuels, agriculture, and even household stoves also make a significant contribution.
