Microplastic Detection, Identification, Quantification and Characterization in Water, Sediment, Soil, Food, Beverages, Air, Biological and Industrial Samples
Microplastics are now recognized as a pervasive global contaminant — detected in the deepest ocean trenches, the highest mountain peaks, Arctic ice cores, human blood, breast milk, and the air we breathe. As one of the leading microplastic testing laboratories in UAE, METS Lab provides scientifically rigorous detection, quantification, and characterization of microplastics across the full spectrum of environmental, food, water, industrial, and biological sample matrices. Regulatory pressure around microplastic contamination is accelerating globally. The European Union, WHO, and national environmental authorities are progressively introducing mandatory monitoring and reporting requirements for microplastics in drinking water, wastewater effluents, food products, and marine environments. In the UAE, increasing environmental stewardship commitments and alignment with international sustainability frameworks are driving demand for credible, third-party microplastic analytical data. Our advanced analytical laboratory combines stereomicroscopy, Fourier Transform Infrared Spectroscopy (FTIR), and Scanning Electron Microscopy with Energy Dispersive X-ray Spectroscopy (SEM/EDS), to deliver particle-level identification, polymer type determination, morphological characterization, and quantitative abundance data across all relevant size classes — from visible microplastics down to the nanoplastic range. We deliver technically defensible, regulatory-ready analytical reports for environmental compliance, product certification, research programs, impact assessments, and legal proceedings.Our Core Microplastic Testing Services Include

Why Microplastic Testing is Important?
What Are Microplastics and Why Do They Matter?
Microplastics are defined as plastic particles smaller than 5 mm in their longest dimension. They are classified as primary microplastics — manufactured at micro-scale for specific applications such as cosmetic microbeads, industrial abrasives, and plastic pellets (nurdles) — and secondary microplastics, which result from the fragmentation of larger plastic items through UV degradation, mechanical abrasion, and chemical breakdown in the environment. Nanoplastics are a subset below 1 μm (or in some definitions below 100 nm), increasingly recognized as a distinct and potentially more bioavailable hazard category. The significance of microplastic contamination extends across multiple dimensions. Environmentally, microplastics accumulate in marine and freshwater ecosystems, are ingested by aquatic organisms across all trophic levels, and serve as vectors for persistent organic pollutants (POPs), heavy metals, and pathogenic microorganisms adsorbed onto their surfaces. From a human health perspective, microplastics have been detected in human blood, lung tissue, placenta, stool, and breast milk, raising concerns about inflammatory responses, endocrine disruption from associated plasticizers and additives, and long-term bioaccumulation effects. Commercially and legally, products and operations found to contribute to or contain elevated microplastic levels face growing regulatory scrutiny, market access restrictions, and reputational risk.Microplastic Testing in Drinking Water & Bottled Water
Drinking water is a primary human exposure pathway for microplastic ingestion. Microplastics enter drinking water systems through source water contamination, treatment process limitations, distribution network degradation, and packaging materials. The World Health Organization (WHO) has identified microplastics in drinking water as a priority research and monitoring concern, and regulatory frameworks requiring standardized monitoring are emerging globally. At METS Lab, we perform microplastic analysis in tap water, treated drinking water, desalinated water, and bottled water using validated sample preparation and analytical protocols. Our testing methodology is aligned with:- ISO/TR 21960:2020 — Plastics in the Environment — State of Knowledge and Methodologies: the ISO framework document establishing definitions, measurement approaches, and reporting guidance for microplastic analysis

Microplastic Analysis in Wastewater & Treated Effluent
Wastewater treatment plants (WWTPs) are significant entry points for microplastics into aquatic environments. Domestic wastewater contains high concentrations of synthetic textile fibres released during laundering, microbeads from personal care products, and fragmented plastic particles from packaging and household materials. While conventional treatment processes remove a substantial proportion of microplastics, the treated effluent discharged to receiving water bodies and the sludge applied to agricultural land both remain significant microplastic vectors. Regulatory requirements for WWTP effluent microplastic monitoring are expanding across Europe and internationally. At METS Lab, we perform microplastic analysis in raw influent, treated effluent, and sewage sludge in compliance with:- ISO/TR 21960:2020 — Plastics in the Environment: analytical framework for wastewater and sludge matrices
- HELCOM Guidelines on Monitoring of Microplastics in Baltic Sea Sediments and Biota — widely referenced protocol for effluent and sediment monitoring program design
Microplastic Analysis in Sediment & Soil
Marine and freshwater sediments act as sinks for microplastic particles, accumulating concentrations orders of magnitude higher than the water column above them. Sediment microplastic monitoring is central to marine environmental impact assessments, port development projects, dredging operations, and coastal zone management programs. Similarly, agricultural soils receiving sewage sludge, compost, or irrigation water represent an increasingly recognized terrestrial microplastic accumulation pathway, with implications for soil ecosystem health, crop contamination, and groundwater quality. At METS Lab, we perform microplastic extraction and analysis in marine, estuarine, and freshwater sediments, and in agricultural and industrial soils, aligned with:- MSFD Technical Subgroup on Marine Litter (TSG-ML) Guidance on Monitoring of Sediment Microplastics — European Marine Strategy Framework Directive guidance for sediment sampling and extraction protocols
- HELCOM Guidelines on Monitoring of Microplastics in Baltic Sea Sediments — international reference protocol for marine sediment microplastic monitoring program design
- GESAMP 2019 Guidelines — sampling design, density separation, and filtration protocols for sediment microplastic extraction
Microplastic Testing in Food & Beverages
Microplastic contamination of food and beverages represents a direct human dietary exposure pathway and is an area of rapidly growing regulatory and consumer concern. Microplastics have been detected in seafood (fish, shellfish, crustaceans), sea salt, honey, beer, bottled water, mineral water, table salt, sugar, and fresh produce. For food businesses, manufacturers, and importers operating in or supplying to the UAE market, independent microplastic testing provides the data needed to demonstrate product safety, support sustainability claims, and proactively address emerging regulatory requirements. Our food and beverage microplastic testing methodology follows:
Airborne Microplastic Monitoring & Atmospheric Fallout Analysis
Airborne microplastics — including synthetic fibres, plastic fragments, and film particles — have been detected in urban, rural, and remote atmospheric environments worldwide. Atmospheric microplastic deposition occurs through wind transport, resuspension of surface deposits, and direct emission from traffic, synthetic textiles, and industrial sources. Occupational exposure to airborne microplastics in manufacturing, textile, and recycling environments represents an emerging health risk. Indoor air quality monitoring for microplastics is increasingly relevant for cleanrooms, laboratories, food production facilities, and healthcare environments. At METS Lab, we perform atmospheric deposition and airborne microplastic sampling and analysis aligned with:- GESAMP 2019 Guidelines — atmospheric fallout sampling protocols using standard deposition collectors
- ISO/TR 21960:2020 — Plastics in the Environment: framework applicable to atmospheric microplastic measurement
- VDI 4257 (German Engineering Association Guideline) — Bioaerosol Measurements in Indoor Air: referenced for indoor microplastic fibre sampling design in cleanroom and food production environments

Polymer Identification & Chemical Characterization
Counting and sizing microplastic particles under a microscope provides abundance data, but polymer identification is essential for source attribution, risk assessment, and regulatory reporting. Different polymer types carry different additive packages, surface chemistry, and contaminant adsorption profiles, making chemical identification a critical component of any comprehensive microplastic characterization program. At METS Lab, we apply a multi-technique analytical approach to polymer identification, combining the complementary strengths of FTIR, and GC/MS to deliver confident polymer type assignment across all relevant particle sizes. Our polymer identification methodology follows:- FTIR Spectroscopy (ATR-FTIR) — the primary technique for bulk and particle-level polymer type identification, matching spectra against reference libraries for confident polymer assignment; effective for particles above approximately 20 μm
- Pyrolysis Gas Chromatography-Mass Spectrometry (Py-GC/MS) — the definitive bulk quantification technique for polymer mass fractions; particularly important for nanoplastic characterization and total polymer mass reporting where particle counting alone is insufficient
- SEM/EDS — high-resolution surface morphology imaging combined with elemental analysis for additive and contaminant identification; distinguishing plastic from non-plastic particles in complex matrices
Sample Preparation — A Critical Step in Microplastic Analysis
The quality of microplastic analysis is fundamentally dependent on the rigor of sample preparation. Contamination introduced during sampling, transport, or laboratory preparation is the most common source of analytical error in microplastic testing. At METS Lab, we apply strict contamination control protocols throughout the entire analytical workflow:- Matrix Digestion: Organic matrix components (biological tissue, food, sludge, sediment organics) are digested using enzymatic protocols (proteinase K, cellulase), alkaline hydrogen peroxide (H₂O₂), or potassium hydroxide (KOH) digestion to remove biological interference without degrading plastic particles. Oxidative digestion protocols (Fenton reagent, persulfate) are applied where enzymatic methods are insufficient.
- Density Separation: Microplastics are separated from high-density mineral particles in sediment and soil matrices using density separation solutions — saturated sodium chloride (NaCl, ρ ≈ 1.2 g/cm³), sodium iodide (NaI, ρ ≈ 1.6–1.8 g/cm³), or zinc chloride (ZnCl₂, ρ ≈6–1.8 g/cm³) — to ensure recovery of all polymer types including PET and PVC which sink in NaCl solution.
- Filtration Cascade: Water and liquid samples are filtered through a cascade of stainless steel or glass fibre filters to capture the full particle size range from 5 mm down to the lower detection limit. Filter selection and pore size are documented and reported.
- Visual Sorting: All particles visually identified as potential microplastics under stereomicroscopy are categorized by shape, colour, and size before instrumental confirmation. Particles exhibiting homogeneous colour, absence of cellular structure, and synthetic appearance are forwarded for spectroscopic confirmation.
