Why Seattle air the quality is the worst in in world two days in line


SEATTLE – Seattle had the worst air qualitative in in world Thursday, with heavy mixture of fog and smoke out skyline, surrounding mountains and space needle.

It was second day in a row that city was the worst air qualitative on earthbeating out well-known polluted cities such as Beijing and Delhi. Seattle air quality index, or AQI, achieved over 240 on Wednesday and Thursday is the level defined as “very unhealthy”. for all groups. It was hard to see the top of a building in the quarter and people wore masks to protect themselves from particulate matter in in air and strong odor of smoke.

According to air IQAir Quality Monitoring Site, Seattle Concentration of PM 2.5 – smallest particles less than 2.5 microns in width – on Thursday afternoon was 38 times higher than the annual guideline recommended by the World Health Organization.

cause forest fires raged in Cascade mountains united with weeks of unusually dry and hot weather. Sunday Seattle broke record for hottest day so late in drop, at 88 degrees. Very little rain has fallen in Washington since June; 56 percent of state in drought, according to the National Oceanic and Atmospheric Administration.

Seattle is at its worst air qualitative in in world “A shocking statistic,” said Maddy Kristell, meteorologist for the National Weather Service. in Seattle. Part of The problem, she explained, is a persistent comb of high pressure that prevented the storm from abating over Seattle.

“That comb was really strong and it was just making no difference in weather models to go through,” she said. That, in combination with temperatures above normal, let the fire burn on for longer than they might otherwise.

cityterrible air comes at a time when researchers are trying to figure out if wildfire smoke is getting worse — and how it affects human health on West coast and beyond. According to a study published last month, day of people in United States Experiencing Extreme Smoke Day Increased Significantly over in past decade.

“Intuitively, if you live in West, you know that things have changed has become smoky,” said Marshall Burke, professor of earth science at Stanford University and one of co-authors of the study. “But our goal was to try to quantify how a lot of.”

Between 2006 and 2010 researchers found less than 500,000 people each year exposed to one day of extreme levels of PM2.5. But between 2016 and 2020, this number climbed to more than 8 million Hotter and drier climates combined with a failure plan and carry out prescribed burnings that can prevent giant wildfires – caused increase in number of Americans are being suffocated, caustic air summer and autumn.

Researchers know that PM2.5 is extremely bad for human health – can exacerbate respiratory and cardiovascular problems and frequent high exposures have been shown to affect cognition and children’s test scores. But, said Burke, no one really knows how short spikes of extremely high air pollution affects health and cognition.

It is not necessary to stay inside fix: air the PurpleAir quality monitoring website showed that even many air sensors in Seattle on Thursday reported on the AQI of 100 to 150 which can be dangerous for many vulnerable groups.

When faced with horrible air quality, Burke recommends staying inside, leaving doors and windows closed and using air purifiers or other filtration systems where possible. Those who don’t have air cleaners can make so-called “Corsi-Rosenthal boxes” or box fans with air filters attached to them. for quick do-it-yourself solution for indoor cleaning air.

However, in the end, researchers just starts scratching the surface of in fire-filled climate future. Poor air quality “affects our lives in a lot of of ways,” Burke said. “We are just beginning to understand how important this is.”
