All that glitters is not gold! A report from @ecowatch (link in my bio): something to think about in the silly season. By Daniel Ross
When it comes to the glitter used in everyday cosmetics, specialty make-up, hair products and party paraphernalia, the negative effects on human health and the environment are indeed far from golden. "They really do get into everything, and despite their tiny size, they can have a devastating impact on humans and non-human animals," wrote Trisia Farrelly, a social anthropologist at Massey University in New Zealand and an expert in waste plastics, in an email to AlterNet.
Glitter is one member of a large family of microplastics—tiny little bits of plastic less than five millimeters in size. Think microbeads, microfibers and fingernail-sized fragments of much larger plastic wastes that have broken down over time. When washed or flushed away, microplastics make their way into our oceans and great lakes, slowly accumulating over time, creating all sorts of health and environmental hazards, the full breadth of which is still being grasped.
For one, there's the issue of how microplastics like cosmetic glitter—made by bonding aluminum with polyethylene terephthalate (PET)—impact sensitive ecosystems. That's because PETs leach out endocrine-disrupting chemicals, which, when eaten by marine life, can cause adverse developmental, reproductive, neurological and immune effects, said Farrelly. In this recent study, microplastics are shown to significantly impact the reproduction rates of oysters.
Then there's the domino-like effect of microplastics through the food-chain, for the sheer volume of microplastics consumed by seafood-loving humans is staggering. This study from the University of Ghent found that Europeans who eat shellfish can consume as much as 11,000 microplastics per year. But what are some of the long-term implications from glitter passing through the food-chain?
PETs attract and absorb persistent organic pollutants and pathogens, adding an extra layer of contamination. Read the rest via link in my profile! #plasticpollution #ecowatch #thinkdifferently @graziauk @voguemagazine @elleuk @marieclairemag
