Yuki Iwamura/Bloomberg via Getty Images The National Weather Service has issued several air quality alerts today. Smoke from wildfire in Canada, including dozens of blazes in Quebec, is flowing south. There are alerts up in the Northeast, along the mid-Atlantic and as far south as North and South Carolina. There are air quality alerts in parts of Ohio, too. For the past several weeks, smoke from the wildfires have been pushing into the U.S. Here are some scenes from around the U.S and Canada.

“Due to the fires, many areas across the forecast area are experiencing very unhealthy levels,” the Pennsylvania Department of Environmental Protection wrote in its forecast. The department warned that elderly people or those with respiratory issues should not go outside. “Please limit outdoor exposure, especially if you are a part of the vulnerable population.” The Wednesday winds throughout Philadelphia acted as the catalyst for the thick plume of smoke that covered the East Coast’s second-largest city, as well as cities in the southern part of Pennsylvania. The city’s health department tweeted on Thursday that “while the smoke in the air from the fires in Canada may lessen today, it can still be dangerous.” City officials suggest the air could improve to orange on the color-coded scale by Thursday afternoon, which would mean the air quality is still unhealthy and that people with heart or lung disease, older adults, children and teens should limit their outdoor exposure. Philadelphia Mayor Jim Kenney (D) While there is optimism the air quality in the city could improve by the weekend, Garrow noted there is some concern the effects of the haze could linger for longer. He described it as “an absolutely unique situation” that he could only compare to the city’s response to covid-19 and the recent chemical spill that threatened to contaminate Philadelphia’s drinking water.

Eat plenty of fruits and vegetables. Get regular exercise. Don't smoke. Control high blood pressure, diabetes, and cholesterol. These are age-old words of wisdom for a healthful life. But when was the last time your doctors told you to avoid exposure to pollution? Accumulating evidence about the impact of pollution on our health suggests that this should be another recommendation — though it wouldn't be easy to follow. What is pollution? A simple description of pollution is anything introduced into the environment by humans and that harms human health or ecosystems. As such, there are many kinds of pollution — in the air, water, and soil — which can take the form of gases, heavy metals, chemicals, bacteria, and even noise. Let's focus here on air pollution. Outdoor air pollution includes the burning of fossil fuels (coal, gas, oil) and wildfires. These generate noxious gases, smog (created by ground-level ozone), and soot (fine particles) that are harmful to breathe. Among the contributors to indoor air pollution are fireplaces and home cookstoves that use gas, coal, or biomass fuels such as wood or crop waste that are sometimes used in low-income countries. Air pollution is a complex and vicious cycle. Its In the United States, air pollution has improved quite a bit since the passage of the How does air pollution affect your health? Numerous studies over the years have repeatedly shown that increased outdoor air levels of fine particulate matter correspond to increased ho...
