Bottled water. There probably isn’t anyone you know who doesn’t drink it sometimes. It’s just so convenient, it’s hard not to take advantage of it. Almost all of it is in plastic bottles and has been a major contributor to landfill and ocean waste. Just this month, bottled water is prominent in the news for yet another bad reason: microplastics and nanoplastics within in specific brands. The researchers are not disclosing the actual brands, but they’re letting the public know what the issues are.

A liter of bottled water contains nearly a quarter of a million pieces of nanoplastic on average, according to new research published in the Proceedings of the National Academy of Sciences.¹Nanoplastics measure less than a micron, so picture a speck of household dust and think of a tiny part of that speck. The new research showed that nanoplastic particles in bottled water measured between 10 to 100 times higher than previously estimated.

Researchers contend that nanoplastics and microplastics, which are about the size of a grain of rice, end up in food and beverages during the manufacturing process as well as through plastic tubing used in machinery and leaching from packaging such as plastic bottles. How exactly they affect our overall health is being studied. So far, it is known that these nano- and micro-plastics can cross the blood-brain barrier, enter the placenta and even show up in urine.²

Dr. Konstantinos Lazaridis, a gastroenterologist who studies the role of environmental factors in liver disease at Mayo Clinic says, “It’s possible that tiny plastic pieces simply pass through most people’s bodies without causing much harm, or it might be that these environmental particles only have an impact in people who already have genetic predispositions to disease.”³

Nevertheless, it seems that avoiding bottled water may be most prudent. Douglas Walker, an analytical chemist at Emory University says, “Additives and chemicals found within plastic, like BPA, have been linked to increased blood pressure and type 2 diabetes; PFAs may affect fertility; and phthalates may interfere with hormones.⁴

So, what is the best way to limit your exposure to nanoplastics and microplastics? Drink filtered tap water whenever possible. Filters that have a pore size of one micron or less can help reduce microplastics in your water; smaller micron pores will be better at filtering out smaller particles. Dr. Walker warns not to use filters that are made of plastic and to use ceramic or carbon filters instead.⁵
