WHO Says Microplastics in Drinking Water Present 'Low' Risk

The UN's health agency on Thursday said that microplastics contained in drinking water posed a "low" risk at their current levels.

However, the World Health Organization (WHO) — in its first report on the potential health risks of microplastic ingestion — also stressed more research was needed to reassure consumers.


The report sums up a small but growing number of scientific studies on the subject and draws its conclusions from them.

Microplastics arise when man-made materials degrade into tiny particles. While the US National Oceanic and Atmospheric Administration classifies them as any type of plastic fragment of less than 5 millimeters (about one-fifth of an inch), most human health concerns are focused on far smaller particles.

More Research Needed

The report's authors concluded that research should focus on chemical additives in plastic and the effects of microplastics small enough to enter tissues.

Most plastic particles in water are more than 150 micrometers in diameter and are excreted from the body. But, the report said, "smaller particles are more likely to cross the gut wall and reach other tissues."

"For these smallest size particles, where there is really limited evidence, we need to know more about what is being absorbed, the distribution and their impacts," said one of the authors, Jennifer De France.

This month is Plastic Free July, the 31 days every year when millions of people pledge to give up single-use plastics.

Did you know that some snakes can fly?

The south Asian paradise tree snake (Chrysopelea paradisi) can launch itself into the air and glide from one tree branch to another. And when it does, it moves its body in waves in something known as aerial undulation. Scientists have long known how the snakes moved. But they didn't know why. Until now.

The oceans could look much emptier by 2100, according to a new study that found that most fish species would not be able to survive in their current habitat if average global temperatures rise 4.5 degrees Celsius by the end of the century, as The Guardian reported.

Independence Day weekend is a busy time for coastal communities as people flock to the beaches to soak up the sun during the summer holiday. This year is different. Some of the country's most popular beach destinations in Florida and California have decided to close their beaches to stop the surge in coronavirus cases.

For some combat veterans, the Fourth of July is not a time to celebrate the independence of the country they love. Instead, the holiday is a terrifying ordeal. That's because the noise of fireworks – loud, sudden, and reminiscent of war – rocks their nervous system. Daily fireworks in many U.S. cities in recent weeks have no doubt been interfering with the sleep and peace of mind of thousands of veterans.

Koala populations across parts of Australia are on track to become extinct before 2050 unless "urgent government intervention" occurs, warns a year-long inquiry into Australia's "most loved animal." The report published by the Parliament of New South Wales (NSW) paints a "stark and depressing snapshot" of koalas in Australia's southeastern state.

NASA is advancing tools like this supercomputer model that created this simulation of carbon dioxide in the atmosphere to better understand what will happen to Earth's climate if the land and ocean can no longer absorb nearly half of all climate-warming CO2 emissions. NASA/GSFC

By Jeff Berardelli

For the past year, some of the most up-to-date computer models from the world's top climate modeling groups have been "running hot" – projecting that global warming may be even more extreme than earlier thought. Data from some of the model runs has been confounding scientists because it challenges decades of consistent projections.
