Dental Floss Might be Associated with Toxic Materials

A new US study has warned from toxic substances that can be transmitted into your body through dental floss, which contains a PFAS chemical substance.

PFAS are resistant to water and grease, and usually interfere with fast-food packaging, waterproof clothing and stain-resistant carpet. Consumers can be exposed to PFAS through the products they use and the food they eat, and even through the air and dust inside their homes.

Previous studies also warned from the risk of using these materials, which contribute to high levels of toxic chemicals. But the new study, published Wednesday in the Journal of Exposure Science & Environmental Epidemiology (JESEE), said it found PFAS in a type of dental floss.

During the study, led by the Silent Spring Institute in collaboration with the Public Health Institute in Berkeley, California, researchers measured 11 different PFAS chemicals in blood samples taken from 178 middle-aged women and then compared blood measurements with the results of interviews in which they asked women about nine behaviors that can lead to increased exposure.

The study’s lead author, Katie Boronow, said in a report published on the Institute's website in conjunction with the study: "We found that Women who flossed with Oral-B Glide tended to have higher levels of a type of PFAS called PFHxS (perfluorohexanesulfonic acid) in their body compared with those who didn't. By using a technique called PIGE spectroscopy, Oral-B Glide products were tested, and we found the acid in the blood of the women."

"We found other PFAS materials in the blood of some women who consume fast food wrapped in paper, or have stain-resistant carpets or waterproof clothing, but the surprise was in the dental floss," she said.

Scientists are concerned about the widespread use of PFAS, especially after studies have shown their health risks.

According to Boronow, "these substances are linked to health effects leading to kidney and testicular cancer, thyroid disease, high cholesterol, low birth weight, low fertility, and immune system problems.”



Oil Washes up on Russia’s Black Sea Coast after Tankers Damaged, Governor Says

Spilled oil has washed up along "tens of kilometers" of the Russian Black Sea coast after two tankers were badly damaged in a storm at the weekend, a local governor said on Tuesday.

Veniamin Kondratyev, the governor of Russia's southern Krasnodar region, said on his Telegram channel that fuel oil had been found along the coast from the districts of Temryuk to Anapa.

"This morning, while monitoring the shoreline, stains of fuel oil were discovered. Oil products washed ashore for several tens of kilometers," he said.

The Volgoneft 212 tanker split in half on Sunday in the Kerch Strait, between the Black Sea and the Sea of Azov, while the Volgoneft 239 ran aground 80 meters (87 yards) from the shore near the port of Taman in the strait.

The more than 50-year-old ships were carrying some 9,200 metric tons (62,000 barrels) of oil products in total, Russian news agency TASS reported, raising fears it could become one of the largest environmental disasters to hit the region in years.

A video posted on Zvezda TV's Telegram channel on Tuesday showed a black, oil-like substance along the coast of the Black Sea resort of Anapa, southeast of the Kerch Strait.

The video showed oil-like stains along a beach strewn with tree branches.

Meanwhile, a video broadcast by the state TV channel Vesti showed several birds covered with oil flapping their wings and struggling to fly.

Russia's Natural Resources and Ecology Ministry said on Monday that fuel oil had leaked into the sea, but the scale of the spillage was still not clear.

Natural Resources and Ecology Minister Alexander Kozlov said some of the fuel oil could have sunk to the seabed due to cold weather.

The shipping industry has raised concern in recent months over the risks and potential for collisions posed by hundreds of "shadow" tankers in open sea lanes, with little incentive for these vessels to follow cleaner shipping standards.

The Kerch Strait, which separates mainland Russia from the Moscow-annexed Crimea region, is a key route for exports of its grain and fuel products.

One member of the Volgoneft 212's crew was killed in Sunday's accident, while all 14 people on the Volgoneft 239 were rescued.
