Uptake characteristics and plant hormone metabolic disruption of bisphenol A in pepper (Capsicum annuum L.) roots under soil exposure
AI summary Read the abstract
Researchers investigated how bisphenol A (BPA) in contaminated soil is absorbed by pepper plant roots, finding that uptake disrupts plant hormone metabolism and impairs growth in ways that vary depending on soil type, raising concerns for food safety in agricultural settings.
Soil contamination by bisphenol A (BPA) has raised considerable ecological and environmental concerns, particularly due to its potential impact on plant growth. However, the interactive effects of BPA and different soil types on soil–plant systems rem

Effects of bisphenol A on root traits and rhizosphere bacteria: exploring the link between rhizosphere bacterial and root growth
AI summary Read the abstract
Researchers found that bisphenol A (BPA) exposure alters both root morphology and rhizosphere bacterial community structure in plants, revealing a complex interplay between soil microbes and plant roots under chemical stress. The study advances understanding of plant-microbe interactions in BPA-contaminated environments.
Polyethylene Terephthalate Microplastics Induce More Pronounced Physiological and Molecular Responses in Pepper Plants than Polyethylene: Insights from Physiological, Transcriptomic, and Metabolomic Perspectives
AI summary Read the abstract
Scientists found that two common plastic types, PE and PET, harm pepper plants by stunting growth and disrupting their natural defense chemicals, with PET (used in bottles and food packaging) causing more damage than PE. Since these plastics are accumulating in farm soils, this raises concerns about crop health and food quality, though more research is needed to understand direct effects on human health.
Transport of Bisphenol A, Bisphenol S and three Bisphenol F isomers in saturated soils
AI summary Read the abstract
Researchers studied how Bisphenol A and its substitutes BPS and BPF move through soil in column experiments, finding all three compounds can leach into groundwater. These plastic-derived endocrine-disrupting chemicals can adsorb to microplastics in soil, with implications for water quality and human exposure.
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.
AI summary Read the abstract
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.
Effect of polyethylene particles on dibutyl phthalate toxicity in lettuce (Lactuca sativa L.).
AI summary Read the abstract
Polyethylene microplastic fragments in soil reduced the uptake of the plasticizer chemical dibutyl phthalate (DBP) into lettuce roots but worsened its inhibitory effects on root growth. The complex interactions between microplastics and co-occurring chemical contaminants like phthalates can alter toxicity in unexpected ways, affecting both plant growth and the safety of food crops.
