DoomsdaysCW<p>Not just human health! The <a href="https://kolektiva.social/tags/Toxic" class="mention hashtag" rel="tag">#<span>Toxic</span></a> Blend of LA’s Urban <a href="https://kolektiva.social/tags/WildfireSmoke" class="mention hashtag" rel="tag">#<span>WildfireSmoke</span></a> Will Have Lasting Health Consequences </p><p>Los Angeles residents are breathing bits of "cars, metal pipes, plastics."<br /> <br />By Zoya Teirstein, January 22, 2025</p><p>“These fires are different from previous quote-unquote ‘wildfires,’ because there are so many structures that burned,” said Yifang Zhu, a professor of environmental health sciences at the University of California, Los Angeles. 'Everything in the households got burned — cars, metal pipes, plastics.'</p><p>"<a href="https://kolektiva.social/tags/Wildfiresmoke" class="mention hashtag" rel="tag">#<span>Wildfiresmoke</span></a> is toxic. Burning trees and shrubs produce very fine <a href="https://kolektiva.social/tags/particulatematter" class="mention hashtag" rel="tag">#<span>particulatematter</span></a>, known by the shorthand PM 2.5, which burrow deep into the lungs and can even infiltrate the bloodstream, causing cold- and flu-like symptoms in the short term, and heart disease, lung cancer, and other chronic issues over time. </p><p>"But the fires that raced through Los Angeles burned thousands of homes, schools, historic buildings, and even medical clinics, blanketing the city in thick smoke. For several days after the first fire started, the city’s air quality index, or <a href="https://kolektiva.social/tags/AQI" class="mention hashtag" rel="tag">#<span>AQI</span></a>, exceeded 100, the threshold, typically seen during wildfires, at which air becomes unhealthy to breathe for children, the elderly, and those with asthma. In some parts of the city, the AQI reached 500, a number rarely seen and always hazardous for everyone. </p><p>"At the moment, air pollution experts know how much smoke fills the air. That’s shown improvement in recent days. But they don’t know what’s in it. 'What are the chemical mixtures in this smoke?' asked Kai Chen, an environmental scientist at the Yale School of Public Health. 'In addition to fine particulate matter, there are potentially other hazardous and <a href="https://kolektiva.social/tags/carcinogenic" class="mention hashtag" rel="tag">#<span>carcinogenic</span></a> organic compounds — gas pollutants, trace metals, and microplastics.'</p><p>"Previous research shows that the spikes in unhealthy air quality seen during such events lead to higher rates of hospitalizations for issues like asthma, and even contribute to heart attacks among those with that chronic disease. A 2024 study on the long-term effects of smoke exposure in California showed that particulate matter from wildfires in the state from 2008 to 2018 contributed to anywhere from 52,000 to 56,000 premature deaths. A health assessment of 148 firefighters who worked the Tubbs Fire, which burned more than 36,000 acres in Northern California in 2017 and destroyed an unusually high number of structures, found elevated levels of the <a href="https://kolektiva.social/tags/PFAS" class="mention hashtag" rel="tag">#<span>PFAS</span></a> known as forever chemicals, <a href="https://kolektiva.social/tags/HeavyMetals" class="mention hashtag" rel="tag">#<span>HeavyMetals</span></a>, and flame retardants in their blood and urine.</p><p>"The L.A. County Department of Public Health has formally urged people to stay inside and wear masks to protect themselves from windblown toxic dust and ash. Air quality measurements don’t take these particles into account, which means the air quality index doesn’t reveal the extent of contaminants in the air. </p><p>"Zhu and her colleagues have been collecting samples of wildfire smoke in neighborhoods near the fires. It’ll be months before that data is fully analyzed, but Zhu suspects she will find a dangerous mix of chemicals, including, potentially, <a href="https://kolektiva.social/tags/asbestos" class="mention hashtag" rel="tag">#<span>asbestos</span></a> and lead — materials used in many buildings constructed before the 1970s. </p><p>"The risk will linger even after the smoke clears. The plumes that wafted over the landscape will deposit chemicals into drinking <a href="https://kolektiva.social/tags/water" class="mention hashtag" rel="tag">#<span>water</span></a> supplies and <a href="https://kolektiva.social/tags/contaminate" class="mention hashtag" rel="tag">#<span>contaminate</span></a># soil. When rains do come, they’ll wash <a href="https://kolektiva.social/tags/ToxicAsh" class="mention hashtag" rel="tag">#<span>ToxicAsh</span></a> into streams and across the land, said Fernando Rosario-Ortiz, an environmental engineer and interim dean of the University of Colorado Boulder environmental engineering program. 'There’s a lot of manmade materials that are now being combusted. The potential is there for contamination,' he said, noting that little research on how toxic ash and other byproducts of wildfires in urban areas currently exists. 'What we don’t have a lot of information on is what happens now.'</p><p>"After the Camp Fire razed Paradise, California, in 2018, water utilities found high levels of volatile organic compounds [<a href="https://kolektiva.social/tags/VOCs" class="mention hashtag" rel="tag">#<span>VOCs</span></a>] in <a href="https://kolektiva.social/tags/DrinkingWater" class="mention hashtag" rel="tag">#<span>DrinkingWater</span></a>. Similar issues have arisen in places like Boulder County, Colorado, where the Marshall Fire destroyed nearly 1,000 structures in 2021, Rosario-Ortiz said, though the presence of a contaminant in a home doesn’t necessarily mean it will be present in high levels in the water. Still, several municipal water agencies in Los Angeles issued preemptive advisories urging residents not to drink tap water in neighborhoods near the Palisades and Eaton fires. It’ll be weeks before they know exactly what’s in the water. </p><p>"As wildfires grow ever more intense and encroach upon urban areas, cities and counties must be prepared to monitor the health impacts and respond to them. 'This is the first time I’ve ever even witnessed or heard anything like this,' said Zhu, who raised her daughter in Los Angeles and has lived there for decades, said. 'Even being in the field studying wildfires and air quality impacts, I never imagined that a whole neighborhood, a whole community in Palisades, would burn down.'"</p><p>Read more:<br /><a href="https://znetwork.org/znetarticle/the-toxic-blend-of-las-urban-wildfire-smoke-will-have-lasting-health-consequences/?utm_source=flipboard&utm_medium=flipboard_rss&utm_campaign=znetwork" target="_blank" rel="nofollow noopener noreferrer" translate="no"><span class="invisible">https://</span><span class="ellipsis">znetwork.org/znetarticle/the-t</span><span class="invisible">oxic-blend-of-las-urban-wildfire-smoke-will-have-lasting-health-consequences/?utm_source=flipboard&utm_medium=flipboard_rss&utm_campaign=znetwork</span></a><br /><a href="https://kolektiva.social/tags/AirPollution" class="mention hashtag" rel="tag">#<span>AirPollution</span></a> <a href="https://kolektiva.social/tags/WaterPollution" class="mention hashtag" rel="tag">#<span>WaterPollution</span></a> <a href="https://kolektiva.social/tags/AirIsLife" class="mention hashtag" rel="tag">#<span>AirIsLife</span></a> <a href="https://kolektiva.social/tags/WaterIsLife" class="mention hashtag" rel="tag">#<span>WaterIsLife</span></a> <a href="https://kolektiva.social/tags/ToxicMaterials" class="mention hashtag" rel="tag">#<span>ToxicMaterials</span></a> <a href="https://kolektiva.social/tags/EnvironmentalDisaster" class="mention hashtag" rel="tag">#<span>EnvironmentalDisaster</span></a> <a href="https://kolektiva.social/tags/EnvironmentalDamage" class="mention hashtag" rel="tag">#<span>EnvironmentalDamage</span></a> <a href="https://kolektiva.social/tags/Pyrocene" class="mention hashtag" rel="tag">#<span>Pyrocene</span></a> <a href="https://kolektiva.social/tags/PyroceneEra" class="mention hashtag" rel="tag">#<span>PyroceneEra</span></a></p>
