Analysis of microplastics

Analysis of microplastics in water

ALS offers analysis of microplastics in water. We degrade organic material before the analysis. The analysis is performed by SEM (scanning electron microscope) and particles between 10 µm and 1 mm can be identified. On request we are able to analyze particles as small as 1 µm. 

Analysis sample container Sample volume
Microplastics in water 250 ml dark glass bottle 250 ml (min.100 ml)

ALS Scandinavia´s laboratory in Stockholm, Sweden has developed this method for analysis of microplastics in water.

The package is called A-4h. Recommended sample container is a 250 ml glass bottle and recommended sample volume is 250 ml (minimum volume is 100 ml).

About microplastics

Microplastics in the environment are subject to intense research and studies reveal that they are present in products we use daily, for example, bottled water and cosmetics. Plastics degrade very slowly in the environment and the large amount of plastics in our water environment has led to an increased focus on the harmful effects to marine organisms. ALS offers analysis of microplastics in water. We are able to identify particles between 10 µm and 1 mm (on request we are able to analyze particles as small as 1 µm). 

What are microplastics?

The definition of microplastics is small plastic particles less than 5 mm, with most microplastics being smaller than 1 mm. Microplastics are very tiny pieces of manufactured plastic (microbeads) used as additives to health and beauty products. Plastic pellets that are used as raw material in the industry are unintentionally spread into the environment during transport and production. These particles are called primary particles. Microplastics can also derive from larger plastic debris that degrades into smaller and smaller pieces. These particles are called secondary particles. 

What are the sources of microplastics?

Studies show that important sources of microplastics in the sea are road wear and abrasion of tyres, artificial turfs, plastic fibres from textiles and industrially produced plastic pellets. Health and beauty products which contain microbeads (for example toothpaste and soap) also contribute to the contamination.

Plastics that are disposed of in the environment instead of being recycled will eventually degrade into smaller plastic particles.

It is uncertain how much of the particles from road wear and artificial turfs are transported to water recipients. However, microplastics from health products and synthetic clothes fibres in washing machines enter the sea via the wastewater.
