Summary
Microplastics are widespread in soil ecosystems, with terrestrial contamination potentially exceeding marine levels. Further research is crucial to understand their impact on soil health and ecosystems.
Area of Science:
- Environmental Science
- Soil Science
- Ecotoxicology
Background:
- Microplastics are increasingly recognized as global soil contaminants.
- Terrestrial microplastic pollution may surpass marine pollution.
- Research on soil microplastics lags behind marine studies.
Purpose of the Study:
- To review current knowledge on soil microplastics.
- To analyze their sources, distribution, migration, and effects.
- To identify research gaps and suggest future directions.
Main Methods:
- Literature review and synthesis of existing research findings.
- Analysis of microplastic characteristics (abundance, polymer type, size, shape).
- Examination of factors influencing microplastic migration.
Main Results:
- Identified transportation, film mulching, and sewage sludge as key sources.
- Highlighted the influence of microplastic characteristics and environmental factors on migration.
- Summarized impacts on soil properties, plants, animals, and microorganisms.
Conclusions:
- Soil microplastic analysis is challenging due to complex matrices.
- Further research is needed to fully understand the ecological risks of soil microplastics.
- Developing innovative analytical methods is essential.

Microorganisms play a pivotal role in maintaining ecosystem balance by recycling essential elements such as carbon, nitrogen, and phosphorus, as well as supporting processes like bioremediation, wastewater treatment, and biofuel production.Microbes in Elemental CyclesIn the carbon cycle, microorganisms decompose organic matter, releasing carbon dioxide via aerobic respiration. This carbon dioxide is subsequently used by photosynthetic organisms to synthesize organic compounds, closing the...

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.
