This review examines how microplastics and nanoplastics enter plants through roots, disrupt growth and photosynthesis, and cause oxidative stress that reduces crop yields. Because these plastic particles can move through plant tissues and into edible parts, they represent a potential pathway for microplastics to enter the human food supply.

Microplastics and nanoplastics (MNPs), are minute particles resulting from plastic fragmentation, have raised concerns due to their widespread presence in the environment. This study investigates sources and distribution of MNPs and their impact on plants, elucidating the intricate mechanisms of toxicity. Through a comprehensive analysis, it reveals that these tiny plastic particles infiltrate plant tissues, disrupting vital physiological processes. Micro and nanoplastics impair root development, hinder water and nutrient uptake, photosynthesis, and induce oxidative stress and cyto-genotoxicity leading to stunted growth and diminished crop yields. Moreover, they interfere with plant-microbe interactions essential for nutrient cycling and soil health. The research also explores the translocation of these particles within plants, raising concerns about their potential entry into the food chain and subsequent human health risks. The study underscores the urgency of understanding MNPs toxicity on plants, emphasizing the need for innovative remediation strategies such as bioremediation by algae, fungi, bacteria, and plants and eco-friendly plastic alternatives. Addressing this issue is pivotal not only for environmental conservation but also for ensuring sustainable agriculture and global food security in the face of escalating plastic pollution.

Micro (nano) plastics uptake, toxicity and detoxification in plants: Challenges and prospects

AI summary Read the abstract

This review examines how micro and nanoplastics are taken up by plants, covering their toxic effects on growth and gene expression as well as potential detoxification strategies. Smaller nanoplastics can penetrate plant cell walls and accumulate in tissues, causing oxidative stress and genetic damage. The findings are important for human health because contaminated crops could transfer microplastics directly into the food supply.

Microplastics and plant health: a comprehensive review of sources, distribution, toxicity, and remediation

AI summary Read the abstract

This review summarizes how microplastics enter soil from agricultural films, sewage sludge, textiles, and cosmetics, then get absorbed by plant roots and transported to edible parts, posing risks to food safety. Exposure to microplastics causes oxidative stress, genetic damage, and disrupts photosynthesis in plants, while also carrying heavy metals and pathogens deeper into the food chain.

Research Progress on the Mechanisms of Terrestrial Plant Uptake, Transport, and Growth Inhibition Responses to Micro (nano) Plastics

AI summary Read the abstract

This review synthesizes current research on how terrestrial plants take up micro- and nanoplastics from contaminated soil, finding that particles can enter through roots, accumulate in plant tissues, block root function, and trigger oxidative damage that stunts growth. These pathways mean that food crops grown in microplastic-contaminated soils could expose humans to plastic particles through the diet, in addition to the harm caused to agricultural productivity.

Impacts of Plastics on Plant Development: Recent Advances and Future Research Directions

AI summary Read the abstract

This review summarizes how microplastics and nanoplastics affect plant growth, from blocking seed germination and root development to causing oxidative stress and DNA damage in plant cells. Nanoplastics are small enough to be absorbed by roots and transported to stems, leaves, and even fruits. These findings are concerning for human health because they show that microplastics can enter the food supply through crops, creating a direct pathway for human exposure through plant-based foods.

Micro (nano) plastic pollution: The ecological influence on soil-plant system and human health.

AI summary Read the abstract

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.
