Il fenomeno della dispersione delle materie plastiche in mare è divenuto in questi ultimi anni una vera e propria emergenza ambientale e sanitaria. In particolare, nelle acque del Mar Mediterraneo esiste una latente ed invisibile minaccia rappresentata dalle microplastiche che, attraverso processi di accumulazione biologica nelle complesse reti trofiche degli ecosistemi marini, producono elevati carichi inquinanti nelle specie ittiche commestibili determinando, così, gravi rischi per la salute pubblica. Occorre, pertanto, sperimentare nuove tecniche di intervento ed ideare urgenti contromisure tese alla risoluzione del problema, come ad esempio l'utilizzo di ceppi batterici in grado di degradare le diverse tipologie di materiale plastico presente in mare e/o la messa in opera di barriere galleggianti lungo i corsi d'acqua continentali per bloccare i rifiuti plastici trasportati dalle vie fluviali verso il mare. La soluzione deve essere, comunque, ricercata a monte riducendo la produzione e l'utilizzo dei materiali plastici ed adottando comportamenti civili e responsabili per contrastare e possibilmente risolvere questa nuova forma di inquinamento marino.

Abstract
Worldwide, the global issue, regarding the waste of plastic debris into the sea. is actually a great environmental pro-blem with serious health effects for mankind. In particular, in the Mediterranean basin, there is a concealed threat represented by microplastics that, through bioaccumulation processes within the trophic nets of marine ecosystems, produces high pollutant loadings in some edible species, causing severe risks for human health. Therefore, it is neces-sary to test new technologies and effective measures to solve this problem as, for instance, the use of bacterial strains able to decompose all the different kinds of plastic debris soluted into the sea or the laying of floating barriers along the watercourses to stop the plastic waste carried by fluvial network towards coastal seas. Anyway, the final solution could be realized, first of all, reducing the production and the use of plastics and taking up polite behaviours to fight successfully against this new kind of marine pollution.File | Dimensione | Formato | |
