Overview
Microplastics (< 5 mm diameter) originate from plastic packaging fragmentation, synthetic textile washing, tyre wear, cosmetic microbeads, and water pipe material degradation. The EU Drinking Water Directive (2020/2184) established the first-ever monitoring framework for microplastics in drinking water.
Health Relevance
Microplastics have been detected in human blood, placenta, lung tissue, liver, and colon. They carry adsorbed persistent organic pollutants (POPs), plasticisers (phthalates, bisphenols), and antimicrobial additives. A 2023 NEJM study found patients with carotid artery plaque containing microplastics had significantly higher cardiovascular event rates.

Controversy & Contested Science
Measurement standardisation is lacking — particle counts vary dramatically by size cutoff, material type, and analytical method (FTIR, Raman, pyrolysis-GC/MS). A 2020 ECHA risk assessment could not determine whether current microplastic exposure poses a demonstrable health risk, but called for precautionary monitoring. Critics argue 'no evidence of harm' in an inadequately studied field is not evidence of safety. The scale of nanoplastic generation — every microplastic eventually fragments into millions of nanoplastics (< 1 μm) — represents an exponential accumulation problem that current monitoring frameworks cannot detect.
