20 years of microplas­tics research reveals lasting impact

After two decades of research on microplastics, it has become clear how significant the impact of these particles is on the environment and potentially on human health. Scientists are calling for international cooperation to address the growing pollution caused by plastic waste and microplastics globally. National regulations alone are not sufficient; global agreements are needed. The United Nations’ Plastic Pollution Treaty presents an opportunity for concrete action.

Microplastics are now found everywhere: in our food, drinking water, and even in our bodies. They are present in more than 1,300 species across various ecosystems, both on land and in water. The harmful effects on wildlife have been well documented. Additionally, evidence is growing that human health may also be affected. According to Professor Richard Thompson of the University of Plymouth, microplastic pollution is permanent. Once these particles enter an environment, they are nearly impossible to remove.

Improved methods for risk assessment

To better understand the ecological risks of microplastics, Professor Bart Koelmans’ team at Wageningen University & Research has developed new methods for risk calculation. These tools help identify which species in an ecosystem are affected by microplastics and to what extent. These insights can assist policymakers in developing solutions for this increasingly pressing issue.
