This study investigates the elemental composition of seawater and macroalgae (red, green, and brown species) in the Russian Black Sea coastal zone following an M-100 fuel oil spill in December 2024. Our findings indicate a limited transfer of chemical elements from the fuel oil into the dissolved phase of the ambient marine environment. Conversely, the sorption and subsequent bioaccumulation of chemical elements by macrophytes proved significantly more pronounced. The most substantial accumulati
