Analytical challenges in detecting microplastics and nanoplastics in soil-plant systems
This systematic review found that no universal, efficient, or cost-effective analytical method exists for detecting microplastics and nanoplastics in soil and plant samples, identifying this as the primary barrier to understanding plastic contamination in food systems. Current techniques like Py-GC/MS and vibrational spectroscopy each have significant limitations, especially for the smallest nanoplastic fractions that may pose the greatest health risks.
The review of nanoplastics in plants: Detection, analysis, uptake, migration and risk
This review examines how nanoplastics are detected, analyzed, taken up by plants, and migrate through plant tissues from roots to edible parts. As nanoplastics are found in agricultural soils, understanding how they enter food crops is critical for assessing human dietary exposure.
Microplastics and nanoplastics: fate, transport, and governance from agricultural soil to food webs and humans
This review examines how microplastics and nanoplastics from agricultural sources like plastic mulch and fertilizers accumulate in soil, get taken up by plants, and enter the food chain.

Microplastics in Soil–Plant Systems: Current Knowledge, Research Gaps, and Future Directions for Agricultural Sustainability
This review summarizes current knowledge about how microplastics affect agricultural soils and the plants growing in them, including changes to soil structure, nutrient availability, and root zone biology. Understanding how microplastics move through the soil-plant system is critical because contaminated crops are a major pathway for these particles to reach the human diet.
Micro (nano) plastic pollution: The ecological influence on soil-plant system and human health.
This review examines how micro- and nanoplastics affect soil health, plant growth, and food quality, finding that these particles accumulate in plant root systems and can reduce crop yields and alter nutritional content. Since contaminated soil and water are increasingly delivering microplastics to food crops, these findings are directly relevant to agricultural food safety.
