Literature Review on Microplastics and Human Health
Summary
Tiny plastic particles called microplastics have been found in human blood, brains, placentas, and even breast milk, according to this review of 2024 research. Scientists are linking these particles to cell damage, hormone disruption, inflammation, and increased risks to heart and brain health, though exactly how much harm they cause is still being studied. The takeaway: microplastics are already inside our bodies, making this an important area to watch as research fills in the missing pieces.
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.
