The Fukushima Daï-ichi nuclear power plant accident led to the release of radioactive cesium (Cs) into the marine environment, affecting local marine life and food chains.
Cs accumulates in marine organisms and is recycled in the food web, impacting species' depuration rates, particularly in demersal fish that are confined to coastlines near the contamination source.
The study proposes a model to illustrate how different fish species (demersal vs pelagic) experience varying levels of contamination based on their mobility and feeding habits, utilizing observational data post-accident.
