Microplastics as Carriers of Radionuclides: An Invisible Threat to Our Seas and Food Chain

Scientific studies reveal that microplastics can act as carriers of radionuclides, creating an invisible threat to the seas and the food chain. Microplastics, originating from various sources, bind to radioactive elements, which can enter marine organisms and reach humans through the food chain. The ability to bind radionuclides is greater in smaller microplastic particles, which are more easily ingested by marine organisms. Cyprus, as an island nation, is particularly vulnerable to this threat. The interaction between microplastics and radionuclides is a new area of concern, as microplastics act as a "Trojan horse", increasing the mobility of dangerous substances in the marine environment.
