Microplastics and Nanoplastics Generated in Kitchen

2025
Cheng Fang, Ravi Naidu

Summary

This study investigated microplastic and nanoplastic generation from common kitchen activities, including food preparation with plastic utensils, heating in plastic containers, and cutting on plastic surfaces, confirming significant particle release into food during routine use. Kitchen-generated nanoplastics represent a poorly characterized but high-frequency human exposure route, since these particles are ingested directly with food and are small enough to cross biological membranes and accumulate in organs.

Microplastics and nanoplastics have secretly entered our daily lives but the extent of the contamination problem is still unknown, because their characterisation is still a challenge, particularly for nanoplastics. Herein we select several case studies to confirm the...
