Forever chemicals, a group of dreaded pollutants,&nbsp;are being found in all kinds of places, even inside human wombs. But imagine a simple solution: A 100 per cent 'cleanup' using LED lights. Is that even possible?

If an experiment made by scientists in Japan is an indication, LED light exposure along with a cocktail of chemicals can isolate, separate and remove the dangerous parts in forever chemicals, scientifically called Per- and polyfluoroalkyl substances or PFAS.

The researchers reportedly managed to 'clean up' the forever chemicals at room temperature, and that too overnight, or just eight hours to be precise.

<h2>Cleaning up forever chemicals with LED: How it works&nbsp;</h2>

For the experiment, researchers at Japan’s Ritsumeikan University used a&nbsp;mixture made of cadmium sulfide nanocrystals, triethanolamine and water. The forever chemicals were then put into this mixture, and exposed to LED lights of 405-nanometer wavelength, burning at around 100 degrees Fahrenheit temperature.

The PFAS used in this experiment were perfluorooctanesulfonate or PFOS.

The aim was to start a photocatalytic reaction that eventually breaks down and separates the fluorine irons of the forever chemicals. The experiment proved to be a success, as per a report in New Atlas.

Not only was the separation and removal of these pollutants done, but the chemical process also freed up some parts of the dreaded PFAS that can be put to good use. These are fluorine ions, which can be used for industrial products.

<h2>What are 'forever chemicals or PFAS'?</h2>

PFAS is the name given to a bunch of chemicals that are resistant to water and extreme heat.

This is possible because of the presence of carbon-fluorine bonds in them.

While they are used in a number of products like water-proof cloths, non-stick cookware and foam used by firefighters, their very resilient qualities also make them dangerous. They are resistant to heat and would require at least 400 degrees Fahrenheit to burn. This makes their disposal near-impossible. PFAS are generally buried in landfills to prevent their further exposure.

Once ingested, they can stay in the human body 'forever', hence the name forever chemicals.

LED lights in room temperature can 'clean up' forever chemicals overnight, suggests study

Copenhagen is celebrating its Annual Festival of lights, the event is in its seventh iteration has in fact thousands of Danish citizens who take part in 7 km run adorned in neon and LED lights.

Denmark: Danish runners wrap themselves in lights at seventh annual Copenhagen light festival

New research has shown that America's rapid adoption of LED lighting might be saving money by using less electricity but it's making it harder to see the stars, due to increased light pollution.&nbsp;

The study published in the journal Science states that the night sky is getting 10 per cent brighter every year. The experts said the light pollution is being driven by the growth of cheaper, cleaner and brighter LED lighting.&nbsp;

Notably, it was in 2007 that the US Congress mandated that&nbsp;all lightbulbs be three times more efficient. Last month, the policy finally kicked into effect, effectively banning incandescent&nbsp;light bulbs in favour of LEDs and other compact fluorescents.&nbsp;

"Artificial lighting that escapes into the sky causes it to glow, preventing humans and animals from seeing the stars. Satellites can measure the light emitted upward, but they are not sensitive to all wavelengths produced by LED lighting or to light emitted horizontally," the study noted.&nbsp;

Consequently, the Milky Way is gradually disappearing from our view and so are the other fainter stars. For researchers, the absence of a dark sky means they are unable to peer deep into space and conduct their research.&nbsp;

According to the American Lighting Association, a body that represents lighting manufacturers,&nbsp;the problem of light pollution is "more extensive than originally thought". On being quizzed by about what was being done to alter the status quo, the body said&nbsp;many of its manufacturers now make shielded outdoor light fixtures to direct light away from the sky.&nbsp;
