As East Texas faced a notably “dangerously hot” July and August, experts have highlighted a hidden heat-related danger associated with a common item: water bottles. Reports from KLTV emphasize the issue.
What’s going on?
According to AccuWeather, parts of East Texas were under a Heat Advisory from August 14 to August 20.
Recently, temperatures neared three digits, with heat index values projected to reach as high as 110 degrees.
Ready.gov defines extreme heat as “a period of high heat and humidity with temperatures above 90 degrees for at least two to three days.”
Meteorologists and public health experts suggest several precautions during a Heat Advisory: minimize exertion and sun exposure, stay in air-conditioned spaces, and maintain good hydration to prevent heat-related illnesses.
However, while staying hydrated is crucial during these hot days, experts have cautioned East Texans about a significant but lesser-known hazard.
Bryan Tuten, a chemistry assistant professor at the University of Texas at Tyler, raised awareness about microplastics from water bottles during an interview with KLTV.
Tuten compared the polymer in water bottles to strands of spaghetti, explaining that when temperatures rise, plastic breaks down much like hot pasta separates more easily.
At around 75 degrees, plastic doesn’t degrade much, but many people leave water bottles in cars, causing temperatures to soar inside.
“The crucial temperature that starts this breakdown is around 140 to 170°F, which is typical in a hot car during summer. At that point, you’re more likely to pull particles or chemicals into your water,” Tuten stated.
Why is this a concern?
Microplastics, defined as plastic particles smaller than 5 millimeters, pose potential health risks that are still being researched. Their small size allows them to infiltrate nearly every aspect of the human body, as well as the environment.
Research has indicated potential reproductive impacts, vascular damage, and even links to cancer associated with microplastics.
Dr. Wei-Chin Ho, a biology assistant professor at UT Tyler, also cautioned about increased microbial contamination risks in extreme heat, aligning with Tuten’s concerns about potential hazards.
“Just because you can’t see it doesn’t mean it isn’t there,” Ho remarked.
What can be done?
Staying informed about risks like microplastics is vital as our understanding evolves.
While it’s tough to eliminate plastic completely, using less plastic—especially in personal water bottles—can help reduce exposure to microplastics.
