Many of us have an overflowing kitchen cupboard of plastic containers to store our leftovers. But as awareness grows over the health and environmental pitfalls of plastic, some consumers may be wondering: Is it time to ditch that stash of old deli containers? From a report: Only 9% of all the plastic waste ever created has been recycled. From its contributions to global heating and pollution, to the chemicals and microplastics that migrate into our bodies, the food chain and the environment, the true cost of this cheap material is becoming more apparent. There are thousands of compounds found in plastic products across the food chain, and relatively little is known about most of them. But what we do know of some chemicals contained in plastic is concerning. Phthalates, for example, which are used to make plastic more flexible and are found in food packaging and plastic wrap, have been found by the Centers for Disease Control and Prevention (CDC) in measurable levels across the US population (including in the body of Guardian journalist Emily Holden). They have been linked to reproductive dysfunction in animal studies and some researchers have suggested [PDF] links to decreased fertility, neurodevelopmental issues and asthma in humans. BPA, another chemical widely added to food plastics and can linings, has been subject to increasing regulations after studies linked the chemical to neonatal and infant brain and reproductive harm. But BPS and BPF, two common replacements used in products marketed as “BPA-free,” may have similar effects to their predecessor: studies out of both the University of Texas and Washington State University found that even at a dose of one part per trillion, BPS could disrupt cell functioning. A 2019 study from New York University linked childhood obesity with BPS and BPF. There are many other chemicals added to plastic during production, and researchers concede that many gaps remain in our understanding of how they affect health and development. But research that is adding to concerns about the “miracle material” is growing.
