When you pour hot water into a cup with a plastic lining, what do you think happens to your coffee? ⠀
In a recent study by Indian Institute of Technology Kharagpur researchers set out to evaluate the degradation of plastic lined films in single-use cups. They found that 4 out of 5 disposable paper cups were lined with HDPE grade of plastic. In the experiment scientists poured hot water (85–90 °C) and left the samples for 15 minutes. ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
Using fluorescence microscopy they discovered that approximately 25,000 micron-sized microplastic particles leached into one cup of water (100 ml). The analysis also found the presence of heavy metals—iron, chromium, and cadmium in particular—in the cup’s plastic lining. The report suggests that the Ingestion of microplastics, ions, and heavy metals regularly while using these single-use products can expose us to potential health risks in the future, like cancer and infertility.
