Mechanisms of polyethylene microplastics on microbial community assembly and carbon-nitrogen transformation potentials in soils with different textures

Researchers used DNA sequencing to examine how polyethylene microplastics affect soil microbial communities and carbon-nitrogen cycling across soils with different textures. They found that microplastics significantly shifted microbial community composition and altered the abundance of genes involved in carbon and nitrogen transformation, with effects varying by soil type. The study suggests that microplastic contamination may disrupt fundamental nutrient cycling processes differently depending on soil characteristics.

Polyethylene microplastic and soil nitrogen dynamics: Unraveling the links between functional genes, microbial communities, and transformation processes

Researchers conducted a six-month experiment to understand how polyethylene microplastics in soil affect nitrogen cycling, a process critical for soil fertility and plant nutrition. They found that while total nitrogen levels stayed stable, microplastics significantly altered the forms of nitrogen present by increasing ammonium and nitrate while decreasing dissolved organic nitrogen. The study suggests that microplastics reshape soil microbial communities and their nitrogen-processing activities, potentially disrupting the natural nutrient balance in agricultural soils.

Interactive Effects of Microplastic Pollution and Global Warming on Soil Carbon and Nitrogen Dynamics in Subtropical Forests

Scientists studied how tiny plastic particles (microplastics) affect forest soil when combined with warming temperatures, and found that these plastics disrupt how soil processes carbon and nitrogen - key nutrients that keep ecosystems healthy. The plastic pollution made soils more sensitive to temperature changes and altered important chemical cycles that plants depend on for growth. This matters because microplastics are everywhere in our environment, and this research shows they could harm the forest ecosystems that clean our air and water, especially as the planet continues to warm.

Microplastic effects on carbon cycling processes in soils

Researchers reviewed how microplastics affect carbon cycling processes in soils, including their influence on microbial activity, plant growth, and litter decomposition. Since microplastics are themselves carbon-based materials, they can directly alter soil carbon stocks while also indirectly shifting microbial communities. The study calls for a major research effort to understand the widespread effects of microplastics on soil functioning and terrestrial ecosystem health.

Microplastic induces microbial nitrogen limitation further alters microbial nitrogentransformation: Insights from metagenomic analysis

Researchers studied how both conventional and biodegradable microplastics affect nitrogen cycling in soil over 120 days. They found that biodegradable microplastics significantly disrupted microbial nitrogen processes by acting as a carbon source that shifted bacterial communities toward nitrogen-fixing species. The findings suggest that even biodegradable plastics in soil can alter nutrient availability in ways that may affect soil fertility and plant growth.

Effects of microplastics on greenhouse gas emissions and the microbial community in fertilized soil

Two particle sizes of microplastics were added to fertilized soil and their effects on dissolved organic carbon, greenhouse gas fluxes, and microbial communities were measured, finding reduced global warming potential due to decreased methane emissions but changes in bacterial and fungal community composition. The study reveals complex interactions between microplastics and soil carbon cycling processes.

Effects of microplastics on soil microorganisms and microbial functions in nutrients and carbon cycling – A review

This review examines how microplastics in soil alter the communities of bacteria and fungi that are essential for recycling nutrients like nitrogen, phosphorus, and carbon. Microplastics can increase certain beneficial bacteria but decrease others that are important for soil fertility, and they also carry toxic chemicals that further disrupt microbial life. The authors note that most studies are short-term lab experiments, and long-term field studies are needed to understand real-world impacts.

Effects of microplastics on soil C and N cycling with or without interactions with soil amendments or soil fauna

A meta-analysis of soil experiments found that microplastics significantly disrupt carbon and nitrogen cycling — the fundamental processes that keep soils fertile and regulate greenhouse gas emissions — especially when microplastics interact with fertilizers, heavy metals, or soil animals like earthworms. The type of plastic and the presence of other stressors compounded the effects, with some combinations causing substantially greater disruption than either factor alone. This matters because agricultural soils are heavily contaminated with microplastics from mulch films and other sources, threatening both food production and climate regulation.
