Microplastics are worse than you think

The EPFL researchers specifically targeted progesterone. It is known as an endocrine disruptor. These are hormone-active substances which, even in the smallest quantities, can damage health in the body by changing the endocrine system. Endocrine disruptors are mainly found in synthetically manufactured materials such as pesticides, solvents, baby products and plastics.

The progesterone contained in the microplastic is released into the digestive tract through chemical reactions with the digestive fluids of the fish. This is the central result of a study jointly carried out by scientists from EPFL, the Federal Institute for Water Supply, Wastewater Treatment and Water Protection (Eawag), Peking University in Beijing and Oklahoma State University and published in the journal “Environmental Science: Processes & Impacts »was published.
