Conférence « Microplastiques : comprendre les risques pour la santé »
Invisible to the naked eye, contamination by micro- and nanoplastics is no longer confined to the oceans. It is now affecting the human body and poses a public health concern. Particles have been detected in the blood, liver, lungs, placenta and even the brain. Beyond their mere presence, they act as a chemical Trojan horse, carrying pesticides, heavy metals and endocrine disruptors deep into the body’s tissues.
A single wash cycle releases hundreds of thousands of plastic fibres. Heated baby bottles directly expose infants to these particles. So-called biodegradable plastics also break down into persistent micro-debris, whilst tyre wear contributes to air pollution. Of the 460 million tonnes produced in 2019, only 9 per cent was recycled. The rest disperses and re-enters the food chain: we breathe it in, we drink it, we ingest it.
Jean DEMARQUOY will explain to us how microplastics pose a risk to our health.
---- Biography ----
Jean DEMARQUOY, a university professor, has devoted more than thirty years of his work to physiology, metabolism and nutrition. Having obtained his PhD from Pierre and Marie Curie University, he undertook postdoctoral research in genetics at Baylor College of Medicine in Houston before continuing his research in Dijon, where he carried out work on energy metabolism.
His research has gradually expanded to cover the links between nutrition, the environment and human health. The author of numerous international scientific publications and several books, he has mentored many students and early-career researchers over the years. He is also involved in expert assessments relating to environmental and health risk evaluation and helps to disseminate scientific knowledge to a wider audience.
