From Aquifer to Tap: Comprehensive Quali-Quantitative Evaluation of Plastic Particles Along a Drinking Water Supply Chain of Milan (Northern Italy)

Researchers conducted the first evaluation of plastic particle contamination along a complete drinking water supply chain in Milan, Italy, from groundwater extraction to household taps. The study found low concentrations of plastic particles, ranging from about 0.3 to 1.9 particles per liter, with cellulose dominating at 76% and no significant increase observed along the distribution chain.

Estimating fossil carbon contributions from chemicals and microplastics in Sweden's urban wastewater systems: A model-based approach

A modeling study estimated that fossil-derived carbon makes up roughly 12–17% of the total carbon flowing into Swedish municipal wastewater treatment plants, with microplastics accounting for about 13% of that fossil carbon fraction. This is relevant because wastewater treatment plants emit greenhouse gases, and IPCC guidelines now require accounting for fossil carbon separately from biogenic carbon in those emissions. The study provides a practical framework for other countries to estimate plastic-derived fossil carbon contributions to wastewater emissions inventories.
