ClearPhysiological and Cellular Ultrastructural Responses of Sesuvium portulacastrum under Cd Stress Grown Hydroponically
Researchers tested how the salt-tolerant plant Sesuvium portulacastrum responds to increasing concentrations of cadmium, a toxic heavy metal. The plant showed strong antioxidant defense mechanisms at lower cadmium levels but experienced significant cellular damage at higher concentrations, including disruption to chloroplasts and mitochondria. The findings suggest this species has moderate tolerance to heavy metal stress, which could make it useful for cleaning up contaminated environments.

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.
The Importance of Humic Acids in Shaping the Resistance of Soil Microorganisms and the Tolerance of Zea mays to Excess Cadmium in Soil
Researchers assessed whether a humic acid soil amendment (Humus Active) could protect maize from cadmium toxicity by modifying the soil bacterial community structure under heavy metal stress. Humic acid treatment improved soil bacterial diversity and reduced cadmium uptake by maize, suggesting that humic preparations can partially restore soil microbiome function and crop health in cadmium-contaminated agricultural land.
The Effects of Coexisting Elements (Zn and Ni) on Cd Accumulation and Rhizosphere Bacterial Community in the Soil-Tomato System
Researchers investigated how coexisting zinc and nickel affect cadmium accumulation in tomato plants and the rhizosphere bacterial community in contaminated agricultural soils, finding that elemental interactions meaningfully alter both Cd uptake by crops and the composition of soil microbial communities.
Assessing stress responses in potherb mustard (Brassica juncea var. multiceps) exposed to a synergy of microplastics and cadmium: Insights from physiology, oxidative damage, and metabolomics
Researchers found that microplastics in soil increased the amount of cadmium, a toxic heavy metal, that mustard green plants absorbed, while also reducing crop yields and photosynthesis. Higher concentrations of microplastics made more cadmium available in the soil, leading to greater accumulation of the metal in the plants. This raises food safety concerns because vegetables grown in microplastic-contaminated soil could contain higher levels of toxic metals that are harmful to human health.
Effect of Harvesting Stage on Cowpea Leaf Nutrient Composition
Researchers studied how the nutritional composition of cowpea leaves changes at different harvesting stages. The study is relevant to food security in sub-Saharan Africa and contributes to understanding how plant nutrient levels are affected by soil health, including contamination by microplastics and agrochemicals.
Unveiling the impacts of microplastics on cadmium transfer in the soil-plant-human system: A review
A meta-analysis found that microplastics significantly increase soil cadmium bioavailability by 6.9% and cadmium accumulation in plant shoots by 9.3%, through both direct surface adsorption and indirect modification of soil pH and dissolved organic carbon. This enhanced cadmium mobility through the soil-plant-human food chain amplifies health risks, as co-ingestion of microplastics and cadmium increases cadmium bioaccessibility and tissue damage.
Foliar-Applied Selenium Nanoparticles Alleviate Cadmium Stress Through Changes in Physio-Biochemical Status and Essential Oil Profile of Coriander (Coriandrumsativum L.) Leaves
This study tested whether foliar application of selenium nanoparticles could help coriander plants resist the toxic effects of cadmium-contaminated soil, finding that selenium nanoparticles reduced cadmium uptake and protected plant physiology and essential oil quality. Protecting crops from heavy metal stress is increasingly important as agricultural soils receive combined contamination from metals and microplastics.
ZnO nanoparticle-based seed priming modulates early growth and enhances physio-biochemical and metabolic profiles of fragrant rice against cadmium toxicity
Researchers studied how zinc oxide nanoparticles applied to rice seeds could help the plants resist cadmium toxicity in contaminated soils. The study found that this seed treatment substantially improved early growth and strengthened the plants' biochemical defenses. These findings suggest a potential strategy for growing crops more safely in soils contaminated with heavy metals.
Research on the Mechanisms of Plant Enrichment and Detoxification of Cadmium
This review examines how plants absorb, transport, and accumulate the heavy metal cadmium from contaminated soil, as well as the detoxification mechanisms plants use to cope with cadmium stress. While focused on cadmium rather than microplastics, the research is relevant because microplastics in soil can alter cadmium mobility and uptake by crops, potentially affecting food safety.
Microplastics alter cadmium accumulation in different soil-plant systems: Revealing the crucial roles of soil bacteria and metabolism
A study found that microplastics in soil can change how much cadmium, a toxic heavy metal, is absorbed by food crops, with the effects varying depending on soil type and the amount of plastic present. By altering soil chemistry and bacterial communities, microplastics reshape how pollutants move through farmland and into the food we eat.
Effects of cadmium contamination on bacterial and fungal communities in Panax ginseng-growing soil
Researchers examined how cadmium (a toxic heavy metal) contamination in soil affects the microbial communities around ginseng crops, finding that even low cadmium levels significantly disrupted bacterial diversity more than fungal diversity. Certain bacterial groups that tolerate cadmium became dominant, while beneficial microbes declined — changes that could affect soil health and ginseng safety.
Effects of microplastics and cadmium co-contamination on soil properties, maize (Zea mays L.) growth characteristics, and cadmium accumulation in maize in loessial soil-maize systems
Researchers studied the combined effects of polyethylene microplastics and cadmium on soil properties and maize growth through pot experiments. They found that microplastics altered soil nutrient availability and, depending on size and concentration, either increased or decreased cadmium uptake by the plants. The study suggests that microplastic contamination in agricultural soils can change how crops absorb toxic heavy metals, with potential implications for food safety.
