The combined toxicity of polystyrene microplastic and arsenate: From the view of biochemical process in wheat seedlings (Triticum aestivum L.)
Researchers found that when wheat seedlings were exposed to both arsenic and polystyrene microplastics together, the microplastics reduced arsenic uptake in roots but dramatically increased arsenic transport to the above-ground parts of the plant — by up to 1,000%. This combined exposure caused more oxidative stress and damage to the plants' photosynthetic systems than arsenic alone. The findings suggest that microplastics in contaminated soil could increase how much toxic metal ends up in the edible parts of crops.

Iron minerals: A frontline barrier against combined toxicity of microplastics and arsenic
Researchers investigated the interactions between microplastics, arsenic, and the iron mineral goethite in soil and their combined effects on wheat germination. They found that while microplastics reduced arsenic accumulation in wheat, the combination of both contaminants still impaired plant growth. The study suggests that goethite can serve as a frontline barrier that mitigates the combined toxicity of microplastics and arsenic in contaminated soils.
Mechanistic insight into the intensification of arsenic toxicity to rice (Oryza sativa L.) by nanoplastic: Phytohormone and glutathione metabolism modulation
Nanoplastics at environmentally realistic levels did not harm rice plants on their own, but when combined with arsenic they made arsenic toxicity significantly worse, reducing plant growth by up to 23%. The nanoplastics increased arsenic uptake by disrupting plant hormones and weakening the plant's natural detoxification systems. This is concerning because rice is a staple food for billions of people, and agricultural soils increasingly contain both nanoplastics and heavy metals.
Indole-3-acetic acid and zinc synergistically mitigate positively charged nanoplastic-induced damage in rice
Positively charged 80 nm polystyrene nanoplastics had the greatest impact on rice seedling growth, reducing dry biomass by 41% and root length by 46%, while supplemental zinc and indole-3-acetic acid together significantly alleviated the nanoplastic-induced growth inhibition.
Zinc ions enhance tolerance to nanoplastics stress in rice seedlings: Advancing the development and optimization of traditional zinc fertilizers
Researchers tested whether traditional zinc sulfate fertilizer could help rice seedlings tolerate polystyrene microplastic stress, as an alternative to zinc oxide nanoparticles which carry their own environmental risks. They found that appropriate zinc levels reduced oxidative damage through different mechanisms in shoots versus roots, restoring photosynthesis and development. The findings offer a practical, lower-risk strategy for protecting crops from microplastic contamination in agricultural soils.
Multiomics analysis reveals a substantial decrease in nanoplastics uptake and associated impacts by nano zinc oxide in fragrant rice (Oryza sativa L.)

Researchers exposed duckweed plants to polystyrene and polymethyl methacrylate nanoplastics under arsenic-induced stress and measured effects on hormones, photosynthesis, and antioxidant responses. They found that nanoplastics altered how plants responded to arsenic toxicity, with some combinations reducing oxidative damage while others worsened it. The study reveals that nanoplastic interactions with heavy metals in plants are complex and depend on the specific plastic type involved.

Researchers investigated the co-exposure effects of polyvinyl chloride microplastics and zinc oxide nanoparticles on purple waxy maize grain quality. Surprisingly, the combination treatment increased ear weight and improved nutritional quality by promoting protein, starch, and amino acid accumulation, suggesting that zinc oxide nanoparticles may help mitigate some negative effects of microplastic soil contamination on crop nutrition.
Single and joint toxicity of polymethyl methacrylate microplastics and As (V) on rapeseed (Brassia campestris L.)
Researchers evaluated the individual and combined toxicity of polymethyl methacrylate microplastics and arsenic on rapeseed plants. They found that nanoscale plastic particles were more toxic than microscale ones, and the combination of nanoplastics with arsenic produced synergistic harmful effects on germination, growth, and arsenic accumulation in plant tissues. The study raises concerns about the combined impact of microplastics and heavy metals on crop safety in contaminated farmland.

Interaction of titanium dioxide nanoparticles with PVC-microplastics and chromium counteracts oxidative injuries in Trachyspermum ammi L. by modulating antioxidants and gene expression
Scientists studied how PVC microplastics and chromium (a toxic heavy metal) together affect the growth of ajwain, an important medicinal and food plant. The combination of these pollutants reduced plant growth, damaged photosynthesis, and increased toxic stress more than either pollutant alone. This is relevant to food safety because agricultural soils are increasingly contaminated with both microplastics and heavy metals, which together could reduce crop quality and nutritional value.
