From drinking water to wastewater, surface water to marine environments, our detection services address the growing concern of plastic pollution in aquatic ecosystems and drinking water supplies.
Understanding Microplastic Contamination
The Global Microplastic Crisis
Why microplastics are emerging as critical water contaminants:
- What are Microplastics? - Plastic particles <5 mm in size (WHO/GESAMP definition) | Nanoplastics: <1 µm (1,000 nm) | Primary microplastics: manufactured small (microbeads in cosmetics, industrial abrasives, pre-production pellets) | Secondary microplastics: degradation of larger plastic items (bottles, bags, textiles, tires) | Composed of various polymers: polyethylene (PE), polypropylene (PP), polystyrene (PS), polyethylene terephthalate (PET), polyvinyl chloride (PVC), polyamide (PA/nylon)
- Sources in Water Systems - Wastewater treatment plant effluent (incomplete removal, 90-99% retained but millions of particles still discharged daily) | Stormwater runoff (tire wear particles, degraded litter, microbeads) | Industrial discharges (textile manufacturing, plastic production, recycling facilities) | Atmospheric deposition (airborne microplastics settle into water bodies) | Breakdown of larger plastic debris in rivers, lakes, oceans | Agricultural runoff (plastic mulch films, irrigation systems) | Synthetic textile washing (fibers shed during laundry cycles, 700,000+ fibers per wash)
- Environmental Persistence & Transport - Extremely persistent - plastics degrade over decades to centuries | Fragmentation continues indefinitely (microplastics → nanoplastics) | Buoyant plastics (PE, PP) travel long distances in surface waters | Denser plastics (PET, PVC) settle in sediments | Biofilm formation alters density and transport behavior | Vertical mixing transports microplastics throughout water column | Long-range transport via ocean currents, rivers (microplastics detected in Arctic, deep ocean trenches)
- Human Health Concerns - Ingestion via drinking water (WHO estimates: 0-4 particles/L in treated drinking water, higher in bottled water) | Potential for translocation across gut barrier (particles <10 µm) | Chemical toxicity from plastic additives (phthalates, bisphenols, flame retardants) leaching in digestive system | Physical effects from particle accumulation (inflammation, oxidative stress) | Vector for pathogen transport (bacteria, viruses colonize microplastic surfaces) | Adsorption of environmental contaminants (POPs, heavy metals, pharmaceuticals) - microplastics as Trojan horses | Long-term health effects largely unknown - emerging research area
- Ecological Impacts - Ingestion by aquatic organisms (zooplankton to whales) - mistaken for food | Bioaccumulation and biomagnification through food webs | Physical harm (gut blockage, reduced feeding, false satiation) | Toxic effects from leached additives on reproduction, development | Disruption of nutrient cycling in aquatic ecosystems | Habitat alteration (microplastics in sediments change substrate properties) | Species-specific impacts (filter feeders particularly vulnerable)
- Regulatory Landscape - No established drinking water limits yet (WHO states no health risk at current levels but data limited) | EU developing regulatory framework for microplastics in environment | California AB 1066 (2018): requires monitoring of microplastics in drinking water | Research and monitoring requirements expanding globally | GESAMP (UN) harmonizing measurement methodologies | Increasing focus on source control (microplastic bans in cosmetics, improved wastewater treatment)
Analytical Challenges for Microplastic Detection
Why Microplastic Analysis is Complex
Unique challenges requiring specialized equipment and expertise:
- Sample Preparation Complexity - Large sample volumes needed (10-100L for drinking water, 1-10L for wastewater) | Concentration via filtration (multiple filter sizes: 5 mm, 1 mm, 300 µm, 100 µm, 50 µm, 20 µm, 5 µm) | Removal of natural organic matter (algae, detritus, biofilms obscure microplastics) - enzymatic or chemical digestion required | Density separation (saturated salt solutions: NaCl, NaI, ZnCl₂) to float plastics away from sediment | Filtration artifacts (filter material contamination, particle losses during transfers) | Extreme care to avoid contamination from laboratory plastics, clothing, air
- Detection & Identification Difficulties - Visual sorting inadequate (misidentification of non-plastic particles, observer bias, time-consuming) | Chemical confirmation required for every suspected particle | Size range spans 5 orders of magnitude (5 mm to 1 µm or smaller) | Irregular shapes (fibers, fragments, films, foams, beads, pellets) complicate automated detection | Transparent and colorless particles difficult to visualize | Degraded/weathered plastics have altered surface properties | No single technique detects full size range and all polymer types
- Polymer Identification - Requires spectroscopic analysis: FTIR (Fourier-Transform Infrared) or Raman spectroscopy | FTIR: particles >50-100 µm (diffraction limit), provides polymer fingerprint, library matching (10,000+ polymer spectra) | Raman: particles >1 µm, laser-based, excellent for small particles but fluorescence interference common | Micro-FTIR: imaging mode for spatial mapping of polymer distribution | Raman microscopy: high spatial resolution but slow for large particle numbers | Pyrolysis-GC/MS: destructive technique, identifies polymer type and additives but no particle morphology
- Quantification Challenges - Report as particles per liter (p/L) or mass per liter (mg/L or µg/L) | Particle counting: labor-intensive, requires imaging each particle | Mass determination: difficult for small particles, aggregates complicate weighing | Size distribution: requires image analysis of hundreds to thousands of particles | Variability between replicates (spatial heterogeneity in water samples) | Detection limit depends on sample volume, smallest filter size, and analytical technique
- Contamination Control - Airborne microplastics ubiquitous (synthetic clothing fibers, dust) | All laboratory consumables potential sources (plastic bottles, pipette tips, tubing, gloves) | Strict protocols required: cotton lab coats, glass/metal equipment only, HEPA-filtered clean benches, positive air pressure labs | Procedural blanks mandatory (>10% of samples) - air blanks, filtration blanks, digestion blanks | Contamination typically 0-5 particles per blank (subtracted from sample counts)
FTIR Spectroscopy (Chemical Identification)
Micro-FTIR (Transmission Mode) - Particles >100 µm analyzed individually | Infrared beam passes through particle on KBr window or diamond compression cell | Generates IR spectrum (fingerprint of polymer functional groups) | Library matching against 10,000+ polymer spectra (>80% match threshold) | Identifies: PE, PP, PS, PET, PVC, PA, PC, and additives | Analysis time: 1-3 min per particle (manual positioning)
FTIR Microscopy (Attenuated Total Reflectance, ATR) - Particles 50-5,000 µm | Diamond ATR crystal in contact with particle | No sample preparation, non-destructive | Better for irregular/thick particles than transmission mode | Spatial resolution: ~10-20 µm
FTIR Imaging (Focal Plane Array, FPA) - Simultaneously images 64×64 pixel array (~5 µm pixel size) | Entire filter scanned automatically (hyperspectral imaging) | Each pixel generates IR spectrum → polymer map | Identifies and counts 1,000+ particles per filter | Analysis time: 4-24 hours per filter (size dependent) | Gold standard for comprehensive microplastic analysis | Commercial systems: Agilent 8700 LDIR, PerkinElmer Spotlight, Bruker Lumos
Raman Spectroscopy
Raman Microscopy (Confocal) - Particles >1 µm (excellent for small microplastics) | Laser excitation (532 nm, 785 nm) generates Raman scatter | Highly specific polymer identification | Spatial resolution: ~0.5-1 µm (better than FTIR) | Limitations: Fluorescence interference (pigments, degraded plastics), sample heating with high laser power, slow (2-5 min per particle)
Raman Imaging - Automated stage scans entire filter | Generates Raman spectrum at each pixel | Polymer maps identify distribution and composition | Excellent for colored/pigmented microplastics (FTIR struggles with dark particles) | Analysis time: 8-48 hours per filter (slower than FTIR imaging)
Surface-Enhanced Raman (SERS, Experimental) - Gold/silver nanoparticles enhance Raman signal 10⁶-10⁸× | Detects nanoplastics (<100 nm) | Research technique, not yet routine
Pyrolysis-GC/MS
Thermal Desorption GC/MS - Bulk sample (filter) heated to 300-700°C in pyrolyzer | Plastics decompose to characteristic monomers/oligomers | GC separates pyrolysis products, MS identifies them | Quantifies total polymer mass (µg to mg) | Identifies polymer types and plastic additives simultaneously | Advantages: High sensitivity, analyzes entire sample, detects additives (phthalates, BPA, flame retardants) | Disadvantages: Destructive (no particle morphology), no individual particle data | Commercial systems: Frontier Lab Multi-Shot Pyrolyzer, Gerstel TDS-GC/MS
Emerging Techniques
Hyperspectral Imaging (Vis-NIR) - Visible and near-infrared spectroscopy (400-2,500 nm) | Rapid imaging (faster than FTIR/Raman) | Identifies major polymer types but less specific than FTIR/Raman | Good for large particles (>500 µm)
Atomic Force Microscopy (AFM) - Nanoscale imaging (<100 nm particles) | Surface topography and mechanical properties | Identifies nanoplastics but slow and expensive | Research applications
Electron Microscopy + EDX - SEM: Morphology at nm resolution | EDX: Elemental composition (identifies chlorine in PVC, etc.) | Identifies weathered/degraded microplastics by surface features | Requires conductive coating (limits spectroscopy follow-up)

Concentration ranges from global monitoring studies:
| Water Type | Sample Matrix | Concentration Range (particles/L) |
Dominant Polymer Types | Common Particle Shapes |
|---|---|---|---|---|
| Drinking Water (Treated) | Tap water from municipal systems | 0-4 (WHO estimate) 0.1-10 (published studies) |
PE (30-40%), PP (20-30%), PET (15-25%), PS (5-15%) | Fibers (60-70%), fragments (20-30%), films (5-10%) |

| Groundwater | Wells, aquifers | 0.1-5 (limited data) |
PE (30-40%), PP (20-30%), PET (15-25%) | Fibers (50-60%), fragments (30-40%) |
| Rivers (Freshwater) | Surface water, subsurface | 0.5-50 (highly variable by location) |
PE (35-45%), PP (25-35%), PS (10-20%), PET (5-15%) | Fragments (40-50%), fibers (35-45%), foams (5-10%) |
| Lakes & Reservoirs | Surface water (drinking water sources) | 1-40 (lower in remote lakes) |
PE (30-40%), PP (20-30%), PET (15-25%), PS (10-20%) | Fibers (50-60%), fragments (30-40%), films (5-10%) |
| Coastal/Estuarine Waters | Surface water near coastlines | 5-200 (higher near urban areas) |
PE (40-50%), PP (25-35%), PS (10-20%), PET (5-10%) | Fragments (45-55%), fibers (30-40%), foams (10-15%) |
| Open Ocean (Surface) | Pelagic waters, gyres | 0.1-100 (gyres: 10-1,000+) |
PE (50-70%, buoyant), PP (20-30%), PS (5-10%) | Fragments (60-70%), foams (15-25%), films (10-15%) |
| Wastewater (Influent) | Raw sewage entering treatment plant | 100-10,000 (avg: 500-2,000) |
PE (30-40%), PP (20-30%), PET (20-30%, textile fibers), PA (5-15%) | Fibers (70-85%, laundry), fragments (10-20%), beads (2-5%) |
| Wastewater (Effluent) | Treated wastewater discharge | 1-100 (90-99% removal) |
PE (30-40%), PP (20-30%), PET (15-25%), PA (10-15%) | Fibers (65-75%), fragments (20-30%), films (5-10%) |
| Stormwater Runoff | Urban stormwater, combined sewer overflows | 50-5,000 (highly variable, event-dependent) |
PE (30-40%), PP (20-30%), PET (15-25%), tire rubber (10-20%) | Fragments (50-60%), fibers (25-35%), tire particles (10-15%) |
Important Notes: Concentrations vary widely depending on analytical method (filter size, identification technique). Smaller filters detect more particles. Studies using <10 µm filters report 10-100× higher counts than >100 µm filters. Polymer percentages approximate - vary by region and water type. Tire wear particles (styrene-butadiene rubber) increasingly recognized as major microplastic source but often excluded from surveys (not true plastics).
Microplastic Size Distribution
Particle abundance by size class (general pattern across water types):
| Size Class | Size Range | Relative Abundance | Detection Method | Characteristics |
|---|---|---|---|---|
| Large Microplastics | 1-5 mm | 5-15% | Visual sorting + FTIR/Raman | Easily visible, fragmented plastic debris, pellets, large fibers |
| Medium Microplastics | 300 µm - 1 mm | 15-25% | Stereomicroscope + micro-FTIR | Visible with magnification, textile fibers, paint chips, foam fragments |
| Small Microplastics | 50-300 µm | 25-40% | Optical microscope + FTIR imaging | Require microscopy, microfibers, tire dust, degraded fragments |
| Very Small Microplastics | 10-50 µm | 30-50% | High-mag microscopy + Raman imaging | Near limit of optical microscopy, secondary degradation products |
| Nanoplastics (Large) | 1-10 µm | Unknown (under-sampled) |
Raman microscopy, pyrolysis-GC/MS | Difficult to distinguish from inorganic particles, require advanced techniques |
| Nanoplastics (Small) | <1 µm (1,000 nm) | Unknown (rarely measured) |
AFM, SERS, TEM, pyrolysis-GC/MS | Likely most abundant numerically, research frontier, health concern (cellular uptake) |
Key Observation: Abundance increases exponentially with decreasing size. For every particle 1-5 mm, there may be 10-100 particles 50-300 µm, and thousands to millions of particles <10 µm. Most studies underestimate total microplastic load due to limited detection of small particles.
