Plastic debris in the environment receives special attention from scientific communities, whereas the radioactivity of plastics and the dynamics of plastic-associated biofilm remain largely unknown. Hence, the current study is addressed plastic-associated biofilms and sediments from coastal areas of Japan to elucidate their characteristics and interaction with radionuclides in the environment. Stable isotope signatures of the biofilms and sediments were also explored based on seasonal variations. The results revealed the potential interaction between plastics and 137Cs within 120 km distance from the Fukushima Daiichi Nuclear Power Plant. The isotopic signatures emphasized the microbial responses against different nutrient conditions and environmental changes in the coastal ecosystem.
