Vegetable-Borne Microplastics: Evidence, Uncertainties, and a Research Agenda for Food-Chain Risk Assessment
Summary
This review study summarizes what we know about tiny plastic particles (called microplastics) that can end up in the vegetables we eat through contaminated water, air pollution, and plastic farming materials. Scientists are concerned these plastic particles might harm both plants and human health, but we don't yet have enough research to know the full risks. The researchers say we need better ways to detect these plastics in food and more studies to understand how dangerous they might be for people who eat contaminated vegetables.
Microplastic (MP) pollution poses an increasing environmental threat, with potential impacts on ecosystems, agriculture, and food chains. While its effects in marine environments are well-documented, the influence of MP contamination on terrestrial crops, particularly vegetables, remains underexplored. This review examines the sources of MPs in agricultural systems, detection techniques such as Fourier Transform Infrared and Raman Spectroscopy, and the associated risks to vegetable production. Microplastics enter fields through contaminated irrigation, atmospheric deposition, and plastic-based farming practices, with potential toxicological effects on plants and human health. The assessment calls for standardized detection methods, sustainable farming practices, and further research on MP contamination's long-term effects.

Micro- and Nanoplastics in Agroecosystems: Plant Uptake, Food Safety, and Implications for Human Health
This review of existing research shows that tiny plastic particles are getting into our food crops through contaminated soil and air, causing stress and damage to the plants. These microplastics have been found in the parts of vegetables we actually eat - including leafy greens, root vegetables, and fruits - which means people may be consuming them in their daily diet. However, scientists still don't fully understand how much plastic we're eating or what the long-term health effects might be.
Microplastic Uptake in Vegetables: Sources, Mechanisms, Transport and Food Safety
This review summarizes current knowledge on how microplastics enter vegetables through soil, water, and air, and how they are transported within plant tissues. Researchers found that microplastics can be taken up through roots and move to edible parts, with uptake varying by plant species, particle size, and soil conditions. The findings highlight that vegetable consumption may be an important but underrecognized pathway for human microplastic exposure.
A critical review on microplastics in edible fruits and vegetables: A threat to human health
This review examines the growing evidence that microplastics are present in edible fruits and vegetables, having been taken up from contaminated soils and irrigation water. Researchers found that agricultural practices like plastic mulching and the use of treated wastewater for irrigation are major contributors to crop contamination. The study raises concerns about dietary microplastic exposure through plant-based foods, which have received less attention than seafood in pollution research.
Microplastic Uptake in Vegetables: Sources, Mechanisms, Transport and Food Safety
This review gathered current knowledge on how microplastics enter agricultural soils and get taken up by vegetable crops, which are a major part of the human diet. Researchers found that microplastics can be absorbed through plant roots and transported to edible parts, with uptake influenced by particle size, plastic type, and soil conditions. The study highlights the need for more research on how microplastic contamination in food crops could affect human health and food safety.
Micro and nano plastics in fruits and vegetables: A review.
This review examined how microplastics contaminate fruits and vegetables through root uptake, surface adhesion, and irrigation water, covering analytical methods for detection and highlighting the role of plants as an underappreciated entry point for plastics into the human food chain.
