Everyday Household Items Made From Black Plastic Can Be Harmful to Human Health

It would be difficult to get through an entire day without coming into contact with plastic, but too much exposure to certain kinds of the material could pose a health risk, according to new research. A study by the University of Plymouth in England has revealed "significant and widespread contamination" of everyday items containing black plastic, such as thermos cups, toys, coat hangers, and Christmas decorations, Co.Design reports.

Black plastic isn't widely recycled because its dark pigment makes it hard for many plastic sorting facilities to detect it via infrared radiation. Nevertheless, the plastic parts of old electronic devices like laptops and music players are often repurposed into common household items. Researchers used X-ray fluorescence spectrometers to examine 600 black plastic items and found the presence of additives that can be harmful to human health, such as bromine, antimony, and lead. Historically, bromine has been used in electronic devices to prevent them from catching fire, but they’re not suitable for food containers or other items (like children's toys) that can come into contact with one's mouth. Their findings were published in Environment International.

"Black plastic may be aesthetically pleasing, but this study confirms that the recycling of plastic from electronic waste is introducing harmful chemicals into consumer products," the study's author, Andrew Turner, said in a statement released by the university. "That is something the public would obviously not expect, or wish, to see and there has previously been very little research exploring this."

As Co. Design points out, the greatest concern is cooking utensils, especially food containers. In the UK, some businesses have vowed to stop using black plastic, including supermarket chains Waitrose and Tesco. In Toronto, some businesses are considering swapping out their black plastics (like coffee cup lids) for materials that can be recycled more easily.

Another University of Plymouth study from January found toxic elements in second-hand children's toys, including bromine, lead, and other substances that can be toxic over time. Beyond the risk to human health, black plastic also harms the environment and introduces contaminants to beaches, the researchers found.

Denver's Temperature Dropped a Record 64 Degrees In 24 Hours

One sure sign summer is over: On Wednesday, residents of Denver, Colorado were experiencing a comfortable 82-degree day. Just before midnight, the temperature dropped to 29 degrees. Between Wednesday and Thursday afternoon, the Denver airport recorded a differential of 79 degrees down to 24 degrees. At one point on Wednesday, a staggering 45-degree drop was seen in the span of just three hours.

All told, a one-day span saw a 64-degree change in temperature, from a high of 83 to a low of 19, a record for the state in the month of October and just two degrees shy of matching Denver’s all-time record drop of 66 degrees on January 25, 1872. On that date, the temperature plummeted from 46 degrees to -20 degrees.

Back to 2019: Citizens tried their best to cope with the jarring transition in their environment, to mixed success. On Wednesday, the city’s Washington Park was full of joggers and shorts-wearing outdoor enthusiasts. Thursday, only the most devoted runners were out, bundled up against the frigid weather.

The cold snap also brought with it some freezing drizzle which prompted several vehicular accidents, including 200 reported during Thursday's morning commute. It’s expected to warm up some in the coming days, but residents shouldn't get too comfortable: Melting ice could lead to potholes.

Invasive Snakehead Fish That Can Breathe on Land Is Roaming Georgia

A fish recently found in Georgia has wildlife officials stirred up. In fact, they’re advising anyone who sees a northern snakehead to kill it on sight.

That death sentence might sound extreme, but there’s good reason for it. The northern snakehead, which can survive for brief periods on land and breathe air, is an invasive species in North America. With one specimen found in a privately owned pond in Gwinnett County, the state wants to take swift action to make certain the fish, which is native to East Asia, doesn’t continue to spread. Non-native species can upset local ecosystems by competing with native species for food and habitat.

The Georgia Department of Natural Resources’ Wildlife Resources Division is advising people who encounter the snakehead—a long, splotchy-brown fish that can reach 3 feet in length—to kill it and freeze it, then report the catch to the agency's fisheries office.

Wildlife authorities believe snakeheads wind up in non-native areas as a result of the aquarium trade or food industry. A snakehead was recently caught in southwestern Pennsylvania. The species has been spotted in 14 states.
