Exposure to air pollution is known to cause a vast array of respiratory health problems, but in a new study, researchers at Columbia University's Mailman School of Public Health have determined that air pollution can also weaken bones.
The paper, published in The Lancet Planetary Health, is the first to document high rates of hospital admissions for bone fractures in communities with elevated levels of ambient particulate matter (PM2.5).
<p>
Unfortunately, as a <a href="https://www.mailman.columbia.edu/public-health-now/news/bad-break-osteoporosis-related-bone-fractures-linked-air-pollution" target="_blank">press release</a> for the study noted, risk of bone fracture admissions is greatest in low-income communities. In the U.S., air pollution is <a href="https://www.niehs.nih.gov/research/programs/geh/geh_newsletter/2016/4/spotlight/poor_communities_exposed_to_elevated_air_pollution_levels.cfm" target="_blank">especially high</a> in poorer communities.
</p><p>
For the study, researchers analyzed osteoporosis-related fracture hospital admissions among 9.2 million people between 2003 and 2010 and found that even a small increase in PM2.5 concentrations would lead to an increase in bone fractures in older adults.
</p><p>
A further eight-year followup of 692 middle-aged, low-income adults found that participants living in areas with higher levels of PM2.5 and <a href="https://www.ecowatch.com/4-million-people-die-each-year-inhaling-black-carbon-1891078957.html">black carbon</a> (the soot that comes from gas and diesel engines, coal-fired power plants and other <a href="https://www.ecowatch.com/tag/fossil-fuels">fossil fuel</a> sources) had lower levels of parathyroid hormone (a key calcium and bone-related hormone) as well as greater decreases in bone mineral density than those exposed to lower levels of the two pollutants.
</p><p>
The study's authors pointed out that the World Health Organization considers osteoporosis the second leading cause of disability globally after cardiovascular disease.
</p><p>
<span></span>The researchers noted that particulate matter can cause systemic oxidative damage and inflammation, which could accelerate bone loss and increase risk of bone fractures in older individuals. Just think of smoking cigarettes as an example. Smoking contains several particulate matter components and has been identified as a risk factor for osteoporosis and bone fracture.
</p><p>
“Decades of careful research has documented the health risks of air pollution, from cardiovascular and respiratory diseases, to cancer, and impaired cognition, and now osteoporosis," said Andrea Baccarelli, MD, Ph.D., chair of Environmental Health Sciences at the Mailman School and the study's senior author.
</p><p>
Baccarelli said that the best way to prevent air-pollution-related diseases is through policies to improve air quality.
</p><p>
<span></span>"Among the many benefits of clean air, our research suggests, are improved bone health and a way to prevent bone fractures," he said.
</p><p>
Since genetic factors are not a major determinant of osteoporosis, the authors suggested that research on the disease should be broadened to examine the impact of environmental factors.

<span></span>In recent weeks, the Indian capital of New Delhi has been blanketed by a thick cloud of smog. As <a href="https://www.ecowatch.com/india-air-pollution-2508401261.html">EcoWatch reported</a>, the air in New Deli has remained "hazardous" for days. Illegal crop burning, vehicle emissions, industrial pollution and dust from sprawling construction sites have contributed to the pollution emergency. By 11 am on Friday, the U.S. embassy air quality <a href="http://clonewdelhi.com/custom/AQI/missionindiaaqi.php" target="_blank">data</a> for PM 2.5 showed levels had reached 550, while the safe limit is 50, according to U.S. embassy standards.

Bringing your own reusable grocery bags when you go shopping is one of the easiest ways to cut down on your plastic consumption — according to the UN Environment Program, up to 5 trillion single-use plastic bags are used globally each year.
The most sustainable option is to use a bag you already have, whether it's an old tote or a laundry basket (thank TikTok for that idea). You can also make your own reusable grocery bags out of T-shirts. But if you'd rather purchase designated reusable grocery bags, here are our recommendations.

<h2>Why switch to reusable bags?</h2><p>The <a href="https://www.unep.org/interactive/beat-plastic-pollution/" rel="noopener noreferrer" target="_blank">UN says</a> people produce 300 million tons of plastic waste each year, and about 60% of the plastic produced since the early 1950s has ended up in a landfill or the natural environment.</p><p>Plastic grocery bags are made from low-density polyethylene (LDPE). Technically, this type of <a href="https://www.ecowatch.com/plastic-recycling-myth-2647706452.html" target="_self">plastic can be recycled</a>. However, in practice, plastic bags easily clog recycling machinery, so <a href="https://millerrecycling.com/ldpe-out-of-landfills" rel="noopener noreferrer" target="_blank">most municipal recycling centers</a> do not accept this type of material. </p><p>A <a href="https://www.epa.gov/sites/production/files/2018-07/documents/smm_2015_tables_and_figures_07252018_fnl_508_0.pdf" rel="noopener noreferrer" target="_blank">study by the EPA</a> showed that only about 6% of the LDPE generated in 2015 was recycled. Other types of plastic, by comparison, were recycled at 18% and 10% rates.</p><div class="redactor-editor" dir="ltr" placeholder="Start writing..." spellcheck="false"></div><p>Although some grocery stores offer plastic bag recycling, the easiest way to get around this is to refuse plastic bags in the first place. Many cities have instituted <a href="https://www.ecowatch.com/new-york-plastic-bag-ban-begins-2645319695.html" target="_self">plastic bag bans</a>, but more often than not, it's up to individuals to choose to make the switch to reusable grocery bags in their day-to-day lives.</p><p><em><em><a href="https://www.ecowatch.com/about-ecowatch-2641507575.html?rebelltitem=47#rebelltitem47" target="_self">Melissa Smith</a> is an avid writer, scuba diver, backpacker, and all-around outdoor enthusiast.
