According to an April 6, 2020 Novus Light Technologies News Release https://www.novuslight.com/optical-tools-enable-the-study-of-microplastics_N10273.html a team of researchers at the University of Rochester in Rochester, New York "... is using a variety of optical methods to look at microplastics in water ... to learn to what extent microplastics ... pass into organs in the human body ... The researchers are ... using ... silicon-based filters ... X-ray photoelectron spectroscopy (XPS) and energy-dispersive X-ray spectroscopy (EDS) techniques ... Once the microplastic particles are identified ... [they are] 'fed' to Caco2 human epithelial cell lines that are widely used as a model of the intestinal epithelial barrier. This will help determine the extent to which the plastic particles are absorbed into the body ... [Many other] groups ... [are] helping us understand the types of microplastics in our water, how they travel through the food chain and the accumulation in the human body ..." #Microplasticss #NanoPlastics PlasticWaste #SingleUsePlastic #FoodPackaging #flexiblepackaging #PlasticPackaging
