[Effects of Combined Stress of Polyethylene and Sulfamethazine on Seed Germination, Seedling Growth, and Physiological Characteristics of Soybean].
A pot experiment found that low concentrations of polyethylene (PE) microplastics partially promoted soybean seed germination and growth, while high concentrations inhibited plant development, and that the antibiotic sulfamethazine caused dose-dependent inhibition that was partially alleviated by low-level PE co-exposure. These combined effects reveal complex interactions between microplastic and pharmaceutical contaminants in agricultural soils that affect crop productivity.
Evaluating the impacts of microplastics on agricultural soil physical, chemical properties, and toxic metal availability: An emerging concern for sustainable agriculture
This study tested how five common types of microplastics affect soil properties and heavy metal availability in agricultural soil over 90 days. Microplastics changed soil structure, nutrient levels, and water-holding capacity, and actually reduced the availability of toxic heavy metals at higher plastic concentrations -- highlighting the complex ways plastic pollution is altering the farmland that produces our food.

Researchers examined the single and combined effects of polystyrene microplastics, norfloxacin, and sulfadiazine on the medicinal food crop Chrysanthemum coronarium. The study found that combined exposure altered nutrient element accumulation and caused ultrastructural damage to plant cells, suggesting that the co-occurrence of microplastics and antibiotics in soil may pose compounded threats to crop safety.
Exposure to microplastics reduces the bioaccumulation of sulfamethoxazole but enhances its effects on gut microbiota and the antibiotic resistome of mice
Researchers used a mouse model to study how microplastics affect the bioaccumulation and health impacts of the antibiotic sulfamethoxazole. While microplastics reduced the overall tissue accumulation of the antibiotic, they enhanced its disruptive effects on gut microbiota and increased antibiotic resistance genes. The findings suggest that microplastics may alter how pharmaceuticals interact with the body in ways that could promote antimicrobial resistance.
Impact of microplastics and aged microplastics on the toxicity of emerging contaminants in the soil
Researchers assessed how polypropylene (PP) microplastics and UV-aged PP microplastics modify the toxicity of eight emerging organic contaminants -- including diclofenac, ciprofloxacin, and diuron -- on soil organism Enchytraeus crypticus, finding that while PP alone had no effect at 5 mg/kg, its presence significantly amplified the toxicity of all tested organic pollutants.
Microplastics impacts the toxicity of antibiotics on Pinellia ternata: An exploration of their effects on photosynthesis, oxidative stress homeostasis, secondary metabolism, the AsA-GSH cycle, and metabolomics
This study found that polyethylene microplastics changed how the medicinal plant Pinellia ternata responds to antibiotic contamination in soil. At low concentrations, microplastics slightly reduced the toxicity of the antibiotic, but at higher levels they worsened the damage to plant photosynthesis, antioxidant systems, and metabolic pathways. The findings show that microplastics can alter how other pollutants affect crop plants, making the real-world impacts of soil contamination harder to predict.
