Description
Rimei Ou and colleagues published a laboratory toxicity study in 2023. They studied metals linked to deep-sea mining waste. Polymetallic nodules on the seabed contain cobalt and nickel. Mining could release these metals into surface waters. The team tested two common phytoplankton species. Phytoplankton are tiny drifting algae that support ocean food webs. Growth and pigment changes were the main measures.
Low metal doses actually sped up algal growth at first. Protein levels rose and stress enzymes stayed lower. High doses caused the opposite pattern. Light-catching pigments fell and protective pigments rose. Proteins dropped and stress enzyme activity peaked. Longer exposure left cells damaged with age. The results warn that mining plumes could disturb ocean life.
