Canadian wildfires have been burning for more than 10 days, and the United States has suffered: New York has become the city with the worst air in the world
Overseas Network, June 7th According to a report by CNN on June 7th, the harmful smoke generated by the burning of wildfires in Canada has continued to drift towards the northeastern United States for several days, causing New York City to once become the major city with the most serious air pollution in the world. Local residents are worried.
Since the wildfire broke out in Nova Scotia, Canada on May 28, the fire has not only spread across Canada, but also caused harmful smoke to envelop New York City and other northeastern regions of the United States. According to data from the website “IQair” of the Swiss air purification information technology company, the air pollution index of New York City ranked first among all major cities in the world in the morning and evening of the 6th Eastern Time.
The smoke produced by wildfires contains PM2.5. After inhaled into the human body, this tiny particle can penetrate deep into the lung tissue and enter the blood, causing asthma, heart disease and other health problems. On the 6th, the concentration of PM2.5 in the air in New York City reached more than 10 times the standard set by the World Health Organization.
In the northeastern United States, such as New York City, which continues to be shrouded in smog, local residents are deeply concerned about the poor air quality in recent days. At least 10 school districts in central New York State canceled various outdoor activities for students on the 6th. The American Lung Association and other organizations also called on residents to stay at home as much as possible. (Shang Ruiwen, Liu Qiang, an intern at Haiwai.com)
