PORTLAND, OR – Portland, Oregon, experienced severely degraded air quality on Monday, August 3, placing it among the top ten major cities globally with the poorest air conditions. The decline in air quality was attributed to smoke originating from distant wildfires.
According to reports, Portland’s air quality index was so high that it surpassed that of other major international cities, including Wuhan, China, and Cairo, Egypt. This ranking placed the city at the 10th position globally for the worst air quality on that specific day.
