Literature Review on Microplastics and Human Health
Summary
Tiny plastic particles have been found in human blood, brains, placentas, breast milk, and other organs, according to this review of 16 studies from 2024. These microplastics enter our bodies through drinking water, food, and air, and have been linked to cell damage, hormone disruption, inflammation, and increased risk of heart and brain problems. While researchers are still working out exactly how harmful they are, the widespread presence of microplastics in our bodies is a growing health concern worth paying attention to.
This independent literature review analyzes 16 peer-reviewed articles from 2024 examining microplastics and human health. Recent 2024 studies confirm microplastics in human blood, brain, placenta, breast milk, liver, and kidney. The review synthesizes evidence on human exposure through drinking water, food, and air, and health effects including cell damage, hormone disruption, oxidative stress, inflammation, neurotoxicity, and cardiovascular risk. It addresses research gaps in nanoplastic detection methods and organ-specific toxicity. Dataset includes:1. Introduction_Vennila - Research overview and identified gaps2.
