Evaluating the Role of Soil Eps in Modifying the Toxicity Potential of the Mixture of Polystyrene Nanoplastics and Xenoestrogen, Bisphenol a (Bpa) in Allium Cepa L

Evaluating the role of soil EPS in modifying the toxicity potential of the mixture of polystyrene nanoplastics and xenoestrogen, Bisphenol A (BPA) in Allium cepa L.

This study examined how nanoplastics and the industrial chemical BPA interact in soil, finding that their combined effects on plant cells were worse than either pollutant alone. Positively charged nanoplastics paired with BPA caused the most damage, including cell death, oxidative stress, and chromosomal abnormalities in onion root cells. The findings suggest that the real-world mix of nanoplastics and chemicals in soil may be more harmful to crops than studies of individual pollutants indicate.

From soil to shoot plant responses to polystyrene nanoplastics and relevance for sustainable food systems

AI summary · Read the abstract

Tiny plastic particles from broken-down polystyrene (a common plastic) can be absorbed by plant roots and leaves, sometimes building up in the parts we actually eat, like grains and leafy greens. This review of existing research found that some crops (rice, lettuce, garlic) are harmed by these plastics, showing stress and stunted growth, while others (wheat) seem more resistant, meaning the risk to our food supply likely depends on what we're growing. The bottom line: we need better testing methods to understand how much of this plastic is ending up on our plates and what that means for our health.

Toxicological Effects of Micro and Nanoplastics on Soil Fauna: Current Research, Advances, and Future Outlook

Researchers reviewed the toxic effects of microplastics and nanoplastics on soil-dwelling organisms such as earthworms and insects, finding that these particles can disrupt reproduction, growth, and survival, with potential ripple effects for soil health and food production.

Integrated Impacts of Microplastics Contaminated Compost on Soil–Plant Systems and Bioaccumulation in Lettuce, Tomato, and Radish

AI summary · Read the abstract

Researchers grew lettuce, tomatoes, and radish in soils amended with four composts of varying microplastic loads, finding that the most contaminated compost reduced early plant growth and resulted in bioaccumulation averaging 118, 81, and 140 microplastic particles per gram dry weight in the respective edible tissues. The study demonstrates that microplastics in compost-amended agricultural soil transfer directly into food crops, posing a direct pathway for human dietary exposure.
