In the framework of the 2022 Science Week, Dr. Joaquim Rovira participated in a workshop to highlight the problem of microplastics in the environment. The event, entitled Welcome to plasticocene, the age of plastic, on the plastisphere, took place on Sunday, November 20, at Museum of Tortosa. The workshop was organized as an educational activity addressed to children aged >8 years, and it was based on experiments to differentiate and identify microplastics, ultimately calculating the amount that is eaten every week.
