What are microplastics (microfibres)?
Definitions of microplastics vary, however, most are classed as plastics that are smaller than 5mm in length down to a few microns across which can be harmful to the environment. Many objects including garments and synthetic materials have the potential to shed microplastics when washed or rinsed in water under normal usage conditions.
Multiple studies have shown that synthetic fibres make up the majority of microplastics which are known as microfibres. Microfibres enter the water system through the washing of clothing made from synthetic materials.

How do microplastics and microfibres cause environmental pollution?
Microplastics are not captured in most effluent treatment plants mainly due to their microscopic size. Microplastics can also absorb and concentrate toxic pollutants from the surrounding environment, making them more harmful.
Microplastics can be consumed by aquatic organisms and have been found in the food chain.
Microplastic pollution may be largely invisible but awareness of the impact it is having on natural environments is growing.
New regulation is encouraging a move away from single-use plastics such as plastic bags, straws and coffee cups. However, this does not address the challenge of microplastics entering water systems from many different products, particularly synthetic products that are washed e.g. polyester clothing, apparel and household products which are laundered or designed to be in contact with water.
Eurofins | BLC Microplastics Testing (Shedding Detection)
Eurofins | BLC have developed a microplastics test method which detects how much microplastic shedding an object will release into water bodies. The Eurofins | BLC test method uses the industry gold standard Gyrowash methodology to identify and analyse whether microplastic fibres (microfibres) are released from synthetic materials, including clothing and textiles.
This method can be adapted and modified to suit your needs and is flexible to include varying product types, including the testing of material samples and whole products. At Eurofins | BLC, we have a range of physical tests that can replicate real-life usage.
Analysis of Microplastic Contamination
With global plastic and microplastic contamination becoming one of the most important environmental discussions of our time, Eurofins | BLC and its partner laboratories offer industry-leading microplastic testing and plastic-type analysis and quantification using the latest FTIR Raman Spectroscopy or Laser Direct Infrared technology LDIR. These technologies combined with microfiltration, collection and SEM photography techniques enable detailed analysis of water, watercourses, sludges, sands, salts, marine matter, food and animal faeces.
