Global Microplastics Symposium

Small particles. Big impact.

Beaches, clothing, bottled water, fish, beer, the air and honey all have one thing in common. They each contain microplastics.

Small particle, big impact.

Less than 5 millimeters in size [1], these confounding microparticles are an urgent concern as they invade food chains and slip through purification systems undetected.  Microplastics are small plastic fibers and particles that originate from everyday objects. Sources [2] of these microplastics include:
- Clothes
- Paints
- Tire dust
- Plastic litter ( bags, bottles, straws)
- Personal care products (microbeads)

Of the tested tap water worldwide, 83% is polluted with microplastic fibers as small as 1/10th of a millimeter [3]. These fibers are dispersed into the environment through everyday activities such as doing laundry, swimming, walking in the streets, or cleaning your face. These microparticulates then end up in freshwater lakes, rivers, municipal treatment plants, and ultimately tap water. These sources affect not only our oceans, lakes, and springs, but the life of organisms that inhabit them. Figure 1 shows an analysis of microplastics from a sample of ocean water collected from the Pellestrina beach in the Lagoon of Venice. All three particles identified in box B have a size between 5 to 10 μm. The yellow particulates were identified as polypropylene, and the grey particulate was identified as PV23 Hoechst Laser pigment.

Entering your local convenience store, you assume purified bottled water is free from harmful particles. Surprisingly, bottled water is no exception to microplastics contamination and, in fact, has higher contamination than tap water. Research at the State University of New York at Fredonia showed that 93% of tested bottled water had microplastics contamination [4]. This has prompted the World Health Organization (WHO) to evaluate all available research on microplastics to help understand whether a lifetime of eating and drinking microplastics could have an effect on human health. Unfortunately, microplastics are not being detected in water purification systems, so they can come from the tap water sources as well as being created from the machinery during the bottling process. This presents a potential liability risk for beverage companies who are just now exploring how best to measure microplastics in their products.

Uncanny health effects

The impact to human health of microplastics contamination is currently unknown as the discovery is relatively new. This means we must find ways to study the composition and prevalence of microplastics as well as their biological and toxicological effects on humans.

Uncanny health effects

As plastic waste breaks down in our environment, it becomes smaller and smaller and turns into fibers. These fibers can absorb toxic chemicals found in the water, such as plant pesticides or pollution from commercial ships. The microplastics then enter the food chain as organisms consume them, transferring these toxins into their bodies. These toxins translocate up the food chain until they are served on our plates. [5]

Although the impact of this toxin transmission from microplastics to fish to humans has yet to be studied, we do know the health effects toxins have on fish and small organisms. The consequences of toxin-sorbed microplastics ingested by fish can be two fold; exposure can be physical, causing tissue damage, or they can be chemical, resulting in bioaccumulation that causes liver toxicity. [2, 7]

Microplastics analytical problem

To distinguish these microparticles, the current strategy is to use a stereo-microscope and tediously separate microplastics from other materials. [6] Unfortunately this visual method is prone to errors due to the extremely small size (<1 mm) of microplastics and the potential for human error and sample contamination. This near-impossible and time-consuming identification process leaves us with a challenging problem.

Microplastics analytical problem

The United States Environmental Protection Agency (EPA) held a Microplastics Expert Workshop in June 2017 to identify and prioritize the information needed to understand the risks and impact that microplastics pose to human life and our ecosystems.[6]  Of all the needs identified for understanding microplastics risks, the expert group agreed that we need to standardize sample collection, extraction, quantification and characterization of polymers at the micron scale (≥1 µm and ≤1 mm in size). These methods would need to be reproducible, representative, accurate, and precise, while following appropriate quality assurance/quality control (QA/QC) practices. Then the information obtained on microplastic shape, polymer type, size, chemical composition and number of particles in a sample can be used to determine what is truly relevant to human and ecological health. The group supported using complementary analytical methods with visual methods and recommends instruments that can accommodate automation and calibration to assure reproducible results from person to person. [6]

The analytical solution

Raman and infrared microscopy can provide the proper identification of a wide range of microplastic particles (1-5000 µm diameter) collected from environmental, industrial, municipal or consumer-product samples.  These techniques use the ability of light to interact with molecules causing them to vibrate at given frequencies. As a result, a spectrum (or a peak pattern of absorbed or emitted frequencies - Figure 2) can provide a “molecular fingerprint” of a microparticulate, providing the identity of its components.

For particles >1 μm, the Thermo Scientific DXR3xi Raman Imaging Microscope offers the analytical power to discern microplastics from other contaminants with high-spatial resolution down to 0.5 µm. The  multivariate analysis algorithms of the Thermo Scientific OMNIC Software allows for spectral identification across a spectral library of plastics and polymers. The DXR3xi Raman Microscope has autoalignment and calibration capabilities to ensure accurate measurements and consistency between operators, supporting recommendations made by the EPA working group. This microscope quickly images large surface areas across the sample filter, making it a fast, reliable method for comparing multiple particulates and identifying their chemical components. For microplastic particles >10 μm, the Thermo Scientific Nicolet iN10 MX FTIR Imaging Microscope offers similar chemical imaging capabilities with speed and efficiency.

What is your opinion of the current state of microplastics pollution as a problem and how much work is needed to better understand the extent of the problem?

The microplastics issue is at the stage where investigations have been implemented worldwide in earnest this year. Big projects have already launched to standardize measurements/determine finer microplastics for a unified analytical solution. In addition, the research of degradation of conventional plastics or biodegradable plastics in the environment field have also been started. Perhaps, a related report will publish in a couple of years as well, then I expect specific regulations will be launched globally.

What is your research focus?

  • Analytical solution development and monitoring for ultra-fine microplastics (0.1 μm to 20 μm) in the environment
  • Elucidation of sources and movement mechanisms and weathering phenomena of global microplastics in the ocean, including ecological impact assessment

What sinks (lakes/oceans/etc…) are you evaluating?

Target samples are: tap water, seawater, sandy beach, food, biodegradable plastic, and living drainage

What specifically are you trying to understand?

I am interested in the following points
  • Determining the concentration of microplastics in the ocean including very fine particles in 0.1-20 μm size range and the prediction of future concentration as well as particle size distribution.
  • Determination of the degree of weathered microplastics

What does your sampling and analysis workflow look like? What are the key challenges associated with trying to analyze microplastics in environmental samples?

At present, development of a solution for sampling and analyzing >20 μm microplastics has been completed, it is now in the commercialization stage. Detailed methods will be published soon, but a brief explanation is as follows,
  • Collect samples using plastic-free equipment
  • Pretreatment using hydrogen peroxide, sodium iodide and enzyme
  • Automatic analysis by Thermo Scientific Nicolet iN10 MX Infrared Imaging Microscope with automatic particle analysis software. For particles <20 μm, this is currently my key research. My problems in method development are likely to be resolved. I am currently searching for a Raman supplier as a partner for the development. I am planning to develop the analysis method with Raman into 2021.

What kind of instrumentation do you use? How useful is it to have more automated solutions for microplastics location and identification?

I am using a Nicolet iN10MX Microscope to define particle size, identification and quantification with OMNIC Picta software.

What is your opinion on the current state of regulations? Are you engaged with regulatory leaders? What are your expectations of national and international regulations on microplastics pollution and monitoring?

  • Microplastic contamination and pollution characteristics are still not known. Sometimes I work with key regulators.  In the future, I expect the investigation of microplastics, as well as policies to control microplastic pollution, will be implemented as follows:
  • The environmental surveys will be conducted for microplastics down to a limit of 20 or 0.2 μm particles (currently the limit can be >300 μm).
  • Polymers that are highly toxic in the environment and that are likely to exist as microparticles in the environment may be banned.
  • It will be recommended to use and adopt biodegradable plastics. At that time, the environmental degradation test would be revised to measure the particle size distribution. As a result, with these new definitions, conventional biodegradable plastics may not meet the requirements.
  • The polymers of microcapsules used in daily necessities are also likely to be replaced with new materials.
