Microplastic and human health with focus on pediatric well-being: a comprehensive review and call for future studies

초록

Although humans are highly dependent on plastics from infancy to adolescence, these materials can degrade into ubiquitous microplastics (MPs) that affect individuals at every stage of life. However, information on the sources, mechanisms, detection techniques, and detrimental ef fects of MPs on children's health from infancy to adole scence is limited. Hence, here we identified and reviewed original research papers published in 2017-2023 across 11 database categories in PubMed, Google Scholar, Scopus, and Web of Science to improve our understanding of MPs with a focus on pediatric wellbeing. These studies found that milk and infant formulas are common sources of MP exposure in infants. Infant formula is the dominant source of MPs in babies, while plastic toys are a common source of MPs in toddlers. Adolescents are frequently exposed to MPs through the consumption of food con taminated with MPs and the use of plastics in food pack aging. Water and air are sources of MP exposure in children from infancy through adolescence. This study thoroughly summarized how MP exposure in children of all ages causes cell damage and leads to adverse health effects such as cancer. With appropriate authorization from the relevant authorities, small amounts of human biological samples (10 g of feces) were collected from volunteers to assess the amounts of MPs in children with the aim of promoting pediatric wellbeing. The samples were then treated with Fenton's reagent, stored in glass jars, and filtered through nonplastic filters. Finally, MPs in children were quantified using stereomicroscopy and characterized using micro Fourier transform infrared spectroscopy.
