Researchers grew tomato plants in soil spiked with polyethylene microplastics alone and combined with lead nitrate at multiple concentrations to compare their toxicity. Both treatments reduced shoot length, fresh and dry weight, and chlorophyll content in a dose-dependent manner, with the combined microplastic-plus-lead treatment causing more severe harm than either pollutant alone.
Melatonin Alleviates Antimony Toxicity by Regulating the Antioxidant Response and Reducing Antimony Accumulation in Oryza sativa L.
Researchers investigated whether melatonin, a natural antioxidant compound, could help rice plants cope with toxic antimony contamination. They found that applying melatonin reduced antimony uptake, decreased oxidative damage, and improved rice growth under antimony stress conditions. The study suggests that melatonin treatments could be a practical strategy for growing rice in soils contaminated with heavy metals.
Brassinosteroids alleviate nanoplastic toxicity in edible plants by activating antioxidant defense systems and suppressing nanoplastic uptake
Scientists discovered that nanoplastics accumulate in the edible parts of tomato plants, but treating the plants with a natural hormone called brassinosteroids reduced nanoplastic uptake and reversed the growth damage. The hormone works by turning off water-channel genes that nanoplastics use to enter the plant. This finding matters for food safety because it suggests a practical way to reduce the amount of nanoplastics people consume through fruits and vegetables.
Assessing the effects of 24-epibrassinolide and yeast extract at various levels on cowpea’s morphophysiological and biochemical responses under water deficit stress
Researchers studied how two natural growth-promoting compounds — 24-epibrassinolide (a plant hormone) and yeast extract — help cowpea plants survive water deficit stress at different dose levels. Their findings suggest these treatments can improve crop resilience in drought conditions, offering practical guidance for farmers facing increasingly unpredictable rainfall.

Dark septate endophyte (DSE) fungal inoculation of chrysanthemum (Dendranthema morifolium) under cadmium stress enhanced root biomass and promoted accumulation of medicinal active ingredients, suggesting DSE as a potential strategy for improving medicinal plant yields in heavy-metal-contaminated soils.
Single and Combined Effect of Cd and Zn on Growth, Metal Accumulation and Mineral Nutrition in Tobacco Plants (Nicotiana tabacum L.)
Researchers tested how cadmium (a toxic heavy metal) and zinc interact when taken up by tobacco plants in contaminated soil, finding that adding zinc significantly reduced cadmium accumulation in the plants. This suggests zinc amendments to agricultural soil could be a practical strategy for reducing toxic metal uptake in food and tobacco crops.
Interaction of Lead and Cadmium Reduced Cadmium Toxicity in Ficus parvifolia Seedlings
Researchers found that lead-cadmium co-exposure in Ficus parvifolia seedlings unexpectedly reduced cadmium toxicity, with lead improving photosynthesis and mitigating the physiological damage typically caused by cadmium alone.
Impacts of root exudates on the toxic response of Chrysanthemum coronarium L. to the co-pollution of nanoplastic particles and tetracycline
Researchers grew Chrysanthemum coronarium under combined nanoplastic and tetracycline exposure and found synergistic oxidative damage and biomass reduction, with root exudates containing malic, oxalic, and formic acids found to partially alleviate toxicity by reducing reactive oxygen species levels.
Buckwheat responds to co-exposure to PLA microplastics and Pb by regulating the synthesis of unsaturated fatty acids and jasmonates
Researchers studied how buckwheat plants respond to combined exposure to biodegradable PLA microplastics and lead contamination in soil. They found that the combination was more damaging than either pollutant alone, reducing plant biomass by up to 50 percent, but the plants activated defense mechanisms by strengthening cell walls and producing protective compounds called jasmonates. The study provides new insights into how plants cope with the emerging problem of microplastic and heavy metal co-contamination in agricultural soils.
Impact of Microplstic and Lead Toxicity on the Terrestrial Plants: a Critical Review
This review examines the toxic effects of microplastics and lead on terrestrial plants, synthesizing evidence that MPs modify soil physicochemical properties and enzymatic activity while lead disrupts root and shoot biomass, leaf development, and growth tolerance. Combined microplastic-lead exposure is found to be more damaging than either stressor alone, with implications for agricultural productivity in contaminated soils.

A Spatially‐Resolved Framework Reveals Contrasting Root and Leaf Strategies to Nanoplastic‐Arsenic Stress in Rice
This study used a new statistical framework to show that rice roots and leaves respond very differently when exposed to both nanoplastics and arsenic simultaneously: roots mount a straightforward additive defense, while leaves show complex antagonistic molecular interactions centred on iron storage. The finding is important for food safety because it reveals that standard toxicity tests on individual stressors may underestimate the risks posed by contaminant mixtures in food crops.
