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.
Effects of polyethylene microplastics on cadmium accumulation in Solanum nigrum L.: A study involving microbial communities and metabolomics profiles
This study found that polyethylene microplastics in soil reduced the ability of a plant known for cleaning up cadmium contamination to absorb the toxic metal. The microplastics changed the soil's microbial community and altered the plant's metabolism in ways that disrupted its natural heavy metal uptake process. This is important because it suggests microplastic pollution in farmland could interfere with natural and engineered soil cleanup strategies for heavy metals.
Cadmium-Induced Oxidative Damage and the Expression and Function of Mitochondrial Thioredoxin in Phascolosoma esculenta
This study investigated how cadmium, a toxic heavy metal, damages a marine invertebrate by causing oxidative stress and disrupting mitochondrial function. The organism's thioredoxin defense system tried to counteract the damage but was overwhelmed at higher cadmium levels. While focused on cadmium toxicity, the findings are relevant to microplastics research because microplastics in marine environments can concentrate and transport heavy metals like cadmium into organisms and up the food chain.
Microplastic-Enhanced Cadmium Toxicity: A Growing Threat to the Sea Grape, Caulerpa lentillifera
Researchers studied how microplastics combined with the heavy metal cadmium affect the sea grape, an ecologically important marine seaweed. They found that microplastics enhanced cadmium accumulation in the seaweed and worsened toxic effects on growth, photosynthesis, and antioxidant defenses. The study highlights that microplastics can amplify heavy metal toxicity in marine plants, posing a compounding threat to coastal ecosystems.
Toxicity and fate of cadmium in hydroponically cultivated lettuce (Lactuca sativa L.) influenced by microplastics
Researchers found that PVC microplastics changed how lettuce plants absorb the toxic heavy metal cadmium when both were present in the growing water. The microplastics initially absorbed cadmium from the water but then altered the plant's uptake patterns, affecting where the metal accumulated in roots versus leaves. This matters because microplastics in agricultural water could change how toxic metals end up in the edible parts of vegetables people eat.

Not relevant to microplastics — this study investigates how the plant transcription factor WRKY45 helps Arabidopsis tolerate cadmium heavy metal stress by activating genes for detoxifying compounds.
Hydroalcoholic extract of Haematoxylum brasiletto protects Caenorhabditis elegans from cadmium-induced toxicity
Researchers found that a plant extract from Haematoxylum brasiletto, a Mexican tree, protected the tiny roundworm Caenorhabditis elegans from cadmium poisoning, a toxic heavy metal found in industrial pollution. The results suggest the extract contains compounds that may counteract the damaging effects of cadmium exposure.
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.
Assessing heterogeneous pollution risks from polystyrene micro(nano)plastics and cadmium to physiology and biochemistry in parsley via a split-root system
Researchers used a split-root system to study how polystyrene micro- and nanoplastics interact with cadmium to affect parsley growth under conditions mimicking real-world uneven soil contamination. They found that cadmium was the primary driver of root damage and oxidative stress, but these effects remained localized to the contaminated side, suggesting the plant can isolate damage. Excessive nanoplastics combined with cadmium on both sides of the root system triggered defense mechanisms that altered the plant's production of beneficial bioactive compounds.
Effect of Polyethylene (LDPE) Microplastic on Remediation of Cadmium Contaminated Soil by Solanum nigrum L.

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.
Polystyrene nanoplastics distinctly impact cadmium uptake and toxicity in Arabidopsis thaliana
In a study using the model plant Arabidopsis, polystyrene nanoplastics increased the uptake and accumulation of the toxic heavy metal cadmium in plant roots. The combined stress of nanoplastics and cadmium caused worse oxidative damage and growth problems than either pollutant alone. This is concerning because it means microplastics in agricultural soil could help toxic metals get into crops more easily, potentially increasing human exposure through food.
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.
Plant growth-promoting bacteria modulate gene expression and induce antioxidant tolerance to alleviate synergistic toxicity from combined microplastic and Cd pollution in sorghum
Scientists found that a beneficial soil bacterium (Bacillus sp. SL-413) can help protect sorghum plants from the combined toxic effects of microplastics and cadmium, a heavy metal. The bacterium boosted plant growth, reduced harmful reactive oxygen species by up to 27%, and reactivated genes that the pollution had shut down. This research points to a nature-based solution for helping food crops survive in microplastic-contaminated soil.
