Microplastics are everywhere—in our food, water, air, and even our clothing. Microplastics accumulate in the brain, blood, lungs, liver, kidneys, and reproductive organs. Microplastics can cause significant health harms and increase the risk for Alzheimer’s, Parkinson’s and other neurodegenerative diseases and can also cause cardiovascular and reproductive problems. Microplastics can also interfere with metabolism and immune function. Major sources of microplastics exposure include tap water, plastic bottles, canned foods, synthetic clothing, and even tea bags.
Black plastic, in particular, has come under enhanced scrutiny for its unique toxicity potential. Things like black spatulas, to-go containers used for food like rotisserie chicken and sushi, black coffee cup lids, can be made from recycled electronics that are full of chemicals like flame-retardants and other forever chemicals that are also associated with cancer, endocrine disruption, and neurological impacts.
Some things you can do to try and minimize your exposure to microplastics are:
avoiding plastic food packaging and cans – especially black plastic;
avoiding heating food in plastic (which can accelerate chemical leaching);
filtering your water with a reverse osmosis system;
choosing natural fiber clothing and avoiding synthetics; and
drinking from glass or stainless steel.
