Microplastics analysis

Microplastics are synthetic polymer particles smaller than 5 millimeters, resulting from the decomposition of larger plastic objects or products containing added microplastics, such as cosmetics and detergents. Currently, with legislation in progress, they are regulated by Regulation (EU) 2023/2055, which restricts them to everyday products. The REACH Regulation (EC) No. 1907/2006 refers to microplastics in chemical substances and mixtures. Finally, the Single-Use Plastics Directive (EU) 2019/904 addresses plastic waste that decomposes into microplastics.

The environmental impact of microplastics is linked to the pollution of aquatic ecosystems, where they can be ingested by fish, birds, and other organisms. They can also interfere with photosynthesis, affecting ecosystem productivity. In addition, they act as vectors for contaminants, adsorbing and transporting pollutants, increasing their dispersion and potential chemical toxicity. They also impact human health by entering the food chain, inhaling, or absorbing them.

The estimated degradation time of microplastics in the environment depends on factors such as the type of polymer, the conditions, and the extent of their degradation.
