Characterization and Health Risk Assessment of Microplastic Release from Infant Feeding Plastic Bottles in Bangladesh

Plastic-based goods are often used for food preparation and storage, but their potential to release microplastics is little recognized. This study examined the possible exposure of newborns to microplastics via consumption of formula from Cat-A baby feeding bottles. Here, it is shown that Cat-A and Cat-B emit microplastics at concentrations as high as 250 particles per liter and 255 particles per liter, respectively. Microplastic leakage is greatly increased by sterilization and exposure to high temperature water, according to scenario studies. A 21-day test of plastic infant feeding bottle of Cat-A and Cat-B revealed periodic oscillations in the release of microplastics. The majority of the particles have a particle size between 501 and 1000 μm and the fiber form predominates. The daily microplastic exposure rate is 208 particles per day.  The results of this research established a baseline prognosis for microplastics in plastic baby goods in Bangladesh, posing a challenge for policymakers to implement the required restrictions and preventative measures to avoid them. Future research on the influence of microplastics on the blood characteristics of animals may provide more conclusive results about the toxicity of microplastics, according to the findings of this study.
