Sensitive groups include people with heart or lung diseases, older adults, pregnant people, children and teenagers, outdoor workers, and others who may suffer undue health impacts from the currently harsh environment.\u00a0<\/p>\n<p>Suburban areas around D.C. received an &#8220;orange&#8221; air quality alert Sunday, meaning conditions are unhealthy for sensitive groups, who are advised to &#8220;make outdoor activities shorter and less intense,&#8221; according to a <a href=\"https:\/\/document.airnow.gov\/air-quality-guide-for-particle-pollution.pdf\" target=\"_blank\" rel=\"noopener\">breakdown<\/a> of the alert index. Air quality is better farther from the city, with parts of Maryland assigned &#8220;yellow&#8221; alerts for Sunday, meaning pollution is &#8220;moderate&#8221; and may only be consequential for unusually sensitive people.<\/p>\n<p>Air quality is expected to steadily improve in the capital and surrounding region over the next few days.<\/p>\n<p>Washington, D.C., was ranked sixth among the world&#8217;s most polluted cities on Sunday, according to <a href=\"https:\/\/www.iqair.com\/world-air-quality-ranking\" target=\"_blank\" rel=\"noopener\">IQAir<\/a>, a Swiss air quality technology company that monitors global pollution levels. Its position trailed Pakistan&#8217;s Lahore and Congo&#8217;s Kinshasa in first and second place, respectively, followed Jakarta, Jerusalem, and Tel Aviv, in that order.<\/p>\n<p>In the United States, major metropolitan areas have seen declining air quality in the wake of fireworks celebrations held on July 4th, <a href=\"https:\/\/www.iqair.com\/newsroom\/fourth-of-july-fireworks-impact-across-usa-2026\" target=\"_blank\" rel=\"noopener\">according<\/a> to IQAir, which said its air quality maps showed increasing concentrations of air pollution across the country overnight Saturday into Sunday. The company said Detroit was briefly ranked as the world&#8217;s most polluted city early Sunday morning, while Chicago and Minneapolis neared the top of its global list, in addition to D.C.<\/p>\n<p>The nation&#8217;s capital put on an especially elaborate Fourth of July spectacle this year, to commemorate the annual holiday and the <span class=\"link\"><a href=\"https:\/\/www.cbsnews.com\/news\/heat-wave-hottest-july-4th-record-temperatures\/\" target=\"_blank\" data-invalid-url-rewritten-http=\"\">250th anniversary of American independence<\/a><\/span>. Its packed event roster included what organizers had said would be the largest fireworks display ever seen in skies over D.C.<\/p>\n<p>Saturday&#8217;s festivities across the U.S. were hampered to varying degrees by a treacherous heat wave that fueled triple-digit temperatures across large swaths of the country, including the capital, where event organizers temporarily paused scheduled programs because of the searing warmth. A heat advisory was in place for D.C., and nearby sections of Maryland and Virginia, until 8 p.m. ET on Sunday, <a
