The impact of microplastics on ocean carbon uptake

Phys · · 999 words · By Ingebjørg Hestvik
Environmental Impact of Microplastics Life Cycle Assessment Marine Carbon Sequestration

Researchers from NTNU have studied how microplastics affect the ability of marine phytoplankton to absorb carbon dioxide, finding the greatest impact in arid and tropical regions. The study aims to integrate these findings into life cycle assessments to better understand the intersection of pollution, climate change, and biodiversity loss.

“Microplastics affect algal growth in various ways. The toxicity of certain types of plastics, such as PVC, is a problem in its own right, but plastic can also reduce the amount of sunlight that penetrates deeper into the water column”
DISPUTED
One source suggests microplastics 'promote algae growth' (Nama et al., 2023), which contradicts the claim that they 'inhibit algal growth'. Other sources discuss general toxicity but do not specifically confirm the sunlight penetration claim.
