ClearMicroplastic in desalinated and seawater: Comparative assessment
Researchers compared microplastic concentrations in desalinated and raw seawater in the Canary Islands, evaluating how well the desalination process reduces plastic particle contamination. Desalination removed a substantial fraction of microplastics but did not eliminate them entirely from drinking water.

Researchers examined the effects of microplastics on pre-treatment processes used in seawater desalination, investigating how microplastic contamination interferes with filtration and other preparatory steps essential to producing potable water from seawater.
Microplastics in small semi-industrial desalination stations and bottled waters: Human exposure and emerging health concerns
Researchers analyzed microplastic contamination in bottled water and small semi-industrial desalination stations in a water-scarce region. The study found microplastics present in both water sources, with higher levels than expected in desalination station output, raising concerns about human exposure through drinking water and highlighting the need for improved filtration standards.
Occurrence and size distribution study of microplastics in household water from different cities in continental Spain and the Canary Islands
Researchers sampled tap water from 24 locations across mainland Spain and the Canary Islands to measure microplastic contamination in household drinking water. They found an average of about 12.5 microplastic particles per cubic meter of tap water, with synthetic fibers being the most common type detected. The study provides one of the first standardized comparisons of drinking water microplastic levels across multiple cities within a single country.
Microplastics from headwaters to tap water: occurrence and removal in a drinking water treatment plant in Barcelona Metropolitan area (Catalonia, NE Spain)
Researchers tracked microplastics through an entire drinking water treatment plant in Barcelona, from river source to tap. The study found microplastic concentrations of about 1 particle per liter in the raw intake water, with sand filtration removing roughly 78% of particles and the overall treatment process achieving 93% removal. Advanced treatments like ultrafiltration and reverse osmosis proved more effective at removing microplastics than conventional ozonation and carbon filtration.
Marine microplastics analysis and their transport in the water column of the Canary Islands region
Researchers analyzed microplastics in seawater samples from the Canary Islands region, studying how oceanographic processes transport plastic particles through the water column.

Identifying microplastic contamination in drinking water: analysis and evaluation using spectroscopic methods
Researchers developed analytical methods to identify and quantify microplastic contamination in drinking water, evaluating extraction efficiency and detection accuracy across different water types and plastic particle sizes. The study assessed health implications based on measured plastic loads in treated water.
Microplastic removal across ten drinking water treatment facilities and distribution systems
Researchers characterized microplastic removal across ten drinking water treatment facilities and found that conventional municipal treatment achieved greater than 97.5% removal, primarily through granular media filtration or ultrafiltration. Untreated source waters contained between approximately 1,200 and 7,200 microplastic particles per liter, with polypropylene, polyethylene, and polyamide being the most common types. The findings provide valuable data on microplastic exposure through drinking water and the effectiveness of existing treatment processes.
Behavior and removal of microplastics during desalination in a lab-scale direct contact membrane distillation system
Researchers explored microplastic behavior in a direct contact membrane distillation system for seawater desalination, finding that the membrane effectively removed microplastics from drinking water while certain plastic types degraded under the high operating temperatures.
Microplastics and nanoplastics contamination in raw and treated water
Researchers analyzed 189 samples of raw, tap, and bottled drinking water for micro- and nanoplastic contamination. They found plastic particles in every sample tested, with raw water sources containing the highest concentrations and treated tap water containing the lowest, though contamination was never fully eliminated. The study suggests that current water treatment processes reduce but do not completely remove plastic particles from drinking water.
Assessment of microplastic contamination in drinking water from an italian plant: An analytical study
Researchers analyzed microplastic contamination at multiple treatment stages in a drinking water plant in northern Italy that processes turbid river water supplemented with groundwater, quantifying particles through sedimentation, flocculation, sand filtration, activated carbon adsorption, and disinfection stages.

Researchers evaluated microplastic occurrence across treatment units and water recirculation systems in two drinking water treatment plants (DWTPs) in Catalonia, Spain, fed by freshwater sources. The study identified potential hotspots where conventional filtration methods failed to fully eliminate microplastics, providing real-world data on how microplastics persist and accumulate within DWTP infrastructure.

Microplastics in the Canary Islands: A Case Study on Transport and Tourist Pressure
Researchers assessed microplastic contamination in the Canary Islands, a region heavily influenced by Atlantic Ocean currents, and found that remote sources contributed significantly to local beach and water accumulation. The study also evaluated emerging contaminants on an EU regulatory watch list, finding limited but concerning data on ecological risks.
Presence of microplastics in the groundwater of volcanic islands, El Hierro and La Palma (Canary Islands)
For the first time, researchers detected microplastics in the groundwater of volcanic islands El Hierro and La Palma in the Canary Islands, finding six different plastic types at concentrations up to 23 particles per liter. Polypropylene and polyethylene from packaging and water pipes were the most common, likely entering groundwater through leaky sewage systems. This finding is alarming because groundwater is often considered a clean water source, and its contamination with microplastics means even remote island communities face exposure through their drinking water.
