Impact of Microplastics on Human Health: A Comprehensive Review

Abstract

Abstract This comprehensive review explores microplastic (MP) contamination in food and Incorporating nanotechnology into food packaging. It covers origins, pathways, health consequences, and analytical challenges. Microplastics (MPs), which are generation due to the breaking down of plastic garbage, presents significant dangers to both the environment and human health. These small particles, sometimes unseen to the unaided eye, can accumulation in ecosystems, harm wildlife, and even entering food chain, potentially cause health issues for humans who consuming contaminated food or water. Exposure occurs through ingesting MPs in food, notably in processed foods, canned goods, and infant milk powder, raising concerns about breast cancer. Nanotechnology in food packaging enhances characteristics but raises migration risks, introducing substances such as phthalates (PAEs), non-PAEs plasticizers (NPPs), bisphenols (BPs), and metal nanoparticles, posing health risks. Microwavable plastic food containers release both intentionally included substances and inadvertently included substances. Consumer attitudes toward nanotechnology are positive, driven by perceived benefits. Analytical techniques for MP detection, including micro-Raman spectroscopy and hyperspectral imaging, face challenges like sample preparation. Multidisciplinary approaches and collaboration are crucial for complex MP analysis in diverse food matrices. The paper discusses MP accumulation in the human body, noting its presence in placentas, bodily fluids, and lower limb joints, raising health questions. Despite challenges in understanding the full health impact, standardized methods and collaboration are urgently needed. This holistic view of MP contamination and nanotechnology in food packaging underscores the necessity of safeguarding food safety and public health against pervasive environmental issues.
