Bottled Water Is Packed Full of Up to 100x More Microplastic Than Expected

As scientists urgently call for studies on the potential health effects of microplastics that make their way into our bodies, we still don't have any easy and effective way of detecting and identifying the smallest of these polluting particles.
So Columbia University environmental chemist Naixin Qian and her colleagues have developed a new imaging technique to expose the insidious petrochemical fragments for all to see.
"People developed methods to see nanoparticles, but they didn't know what they were looking at," says Qian, explaining that unlike old detection methods which can only provide bulk estimates of present particles, the new technique not only distinguishes individual particles but allows for their identification as well.
Nanoplastics are bits of plastic less than a micrometer in size, produced as a side effect of many industrial processes as well as the degradation of larger plastic products.
