Microplast­ics in bottled water might be a big deal

- Mike Szydlowski

COLUMBIA, Mo. – Disposable water bottles are a concern for many because, first, they are an environmen­tal nightmare. Second, they are incredibly overpriced. But let’s ignore both those facts for a moment and think about that refreshing cold bottle of water on a hot day.

Imagine opening a bottle of water, expecting a pure and refreshing drink, only to learn that you’re also consuming tiny particles known as microplast­ics. Recent studies have raised concerns about the presence of these minuscule particles in bottled water and their potential impact on health and the environmen­t.

Findings from Columbia University and Rutgers University have unveiled alarming levels of microplast­ics and nanoplasti­cs in bottled water, far surpassing previous estimates.

The study, published in the Proceeding­s of the National Academy of Sciences, discovered about 240,000 plastic fragments per liter, challengin­g our perception­s of water purity.

Microplast­ics, larger than nanoplasti­cs, alongside these even tinier particles, pose potential health risks due to their ability to be mistaken for natural cell components. Employing advanced techniques like stimulated Raman scattering (SRS) microscopy, researcher­s identified these particles, shedding light on the growing issue of plastic pollution.

Microplast­ics are plastic particles smaller than five millimeter­s.

They can come from larger plastic items that degrade over time or from consumer products like cosmetics that purposeful­ly have microplast­ics in their formula. Unfortunat­ely, these tiny particles have found their way into our oceans, rivers and, now, bottled water.

The widespread use of plastics and inadequate disposal have led to an increase in microplast­ic pollution. As plastics break down, they form microplast­ics, which are then ingested by marine life and can make their way up the food chain to humans.

The discovery of microplast­ics in bottled water suggests that no water source is immune to contaminat­ion, highlighti­ng the pervasive nature of plastic pollution.

Scientists also tested tap water. Microplast­ics were detected in the tap water, but in much smaller quantities. More testing will have to be done to figure out the cause.

While research is still ongoing, there is concern about the potential health impacts of consuming microplast­ics. These particles can carry toxins that, once ingested, may pose risks to human health. Additional­ly, the long-term effects of microplast­ic ingestion are not yet fully understood, raising questions about chronic exposure.

What are the consequenc­es of 80plus years of microplast­ic build-up in the blood and tissue? This unknown is what scientists are most worried about.

This study emphasizes the urgent need for further research on the health implicatio­ns of plastic consumptio­n and calls for a reevaluati­on of our reliance on plastic products.

Choosing tap water over bottled water and supporting policies aimed at reducing plastic waste can help minimize our exposure to microplast­ics and protect the environmen­t.
