Think about this concept: over the past few decades, plastics have been so synonymous with the world’s packaging and products, that it is now present within many things we consume, and even the air we breathe. According to a recent publication, microplastics ranging in size from 5 mm in diameter—roughly the length of a short-grain of rice—down to 10 nm—1/7500th the width of a human hair—are being consumed, and even inhaled. An overview in Time magazine underscores the fact that air, bottled water, and seafood are the largest sources of consumed microplastics, and that people ingest 90,000 particles of plastic per year if they consume bottled water alone; tap-water drinkers incur roughly 4,000 particles of microplastic per year. Analysis of data from 26 studies that measured how many microplastic particles were in the foods people ate or the air they breathed included data on plastic concentrations in seafood, added sugars, salts, beer, water and air, but none on grains, vegetables, beef and poultry. Using U.S. dietary guidelines and respiration rates from the U.S. Environmental Protection Agency, estimates were made into how many microplastics Americans were consuming just from these foods and from breathing. Researchers determined that Americans ingest an estimated 74,000 to 121,000 microplastic particles every year; this number is likely low, however, since data were lacking from many other likely sources of microplastics. There are no known implications for the consumption of these plastics on human health, but one thing is for certain: microplastics are a part of us.
