The impacts of microplastics and biofilms mediated interactions on sedimentary nitrogen cycling: A comprehensive review

Effects of plastispheres and pristine microplastics on sediment microbial communities and nitrogen cycling under global warming

The Effect of N Mineralization, Nitrification and Ammonification Rates in Soils Contaminated with Microplastics

AI summary · Read the abstract

Researchers found that polypropylene, polyethylene, and PET microplastics all disrupt soil nitrogen cycling, with polypropylene having the most harmful effect — reducing the availability of nitrogen that plants need to grow, raising concerns about long-term agricultural soil health in contaminated areas.

Microplastic Pollution in Marine Environment: Occurrence, Fate, and Effects (With a Specific Focus on Biogeochemical Carbon and Nitrogen Cycles)

AI summary · Read the abstract

Marine sediments have emerged as major sinks for microplastic particles, where they disrupt biogeochemical carbon and nitrogen cycling in ways that could alter the ocean's capacity to regulate climate. The interference with nutrient cycles adds a systemic ecological dimension to microplastic pollution beyond the direct toxicity effects on individual organisms.

Microplastics in Soils and Sediment: Sources, Methodologies, and Interactions with Microorganisms

AI summary · Read the abstract

Microplastics in soils and sediments interact with microorganisms in complex ways, affecting microbial community structure and facilitating the spread of antibiotic resistance genes. These interactions highlight that microplastic pollution poses ecological risks beyond physical contamination, potentially disrupting soil health and agricultural systems.

Microplastics in Soils and Sediment: Sources, Methodologies, and Interactions with Microorganisms

AI summary · Read the abstract

Researchers reviewed the sources, measurement methods, and ecological interactions of microplastics in soils and sediments, highlighting that terrestrial plastic pollution is substantial and poorly understood, and that microplastics in soil can affect microbial communities in ways that may ripple through food webs and nutrient cycles.
