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.
The effects of Micro/Nano-plastics exposure on plants and their toxic mechanisms: A review from multi-omics perspectives.
A multi-omics review of micro/nanoplastic effects on plants found that plastic exposure disrupts gene expression, protein function, and metabolic pathways across multiple plant systems, with potential consequences for crop yield and agricultural food safety.
Biochemical and transcriptomic responses of buckwheat to polyethylene microplastics
Researchers grew buckwheat in soil contaminated with polyethylene microplastics and found that higher concentrations disrupted the plant's growth, photosynthesis, and antioxidant defenses. The microplastics were able to invade the roots and lodge in the plant's internal transport tissues. This is concerning for food safety because buckwheat is a widely consumed crop, and microplastics entering through the roots could potentially reach the parts of the plant that people eat.
Transcriptomics, proteomics, and metabolomics interventions prompt crop improvement against metal(loid) toxicity
This review examines how advanced molecular analysis tools -- transcriptomics, proteomics, and metabolomics -- are helping scientists understand how plants respond to toxic metals in contaminated soil. While focused on metal toxicity rather than microplastics directly, these same tools are being used to study how microplastics interact with heavy metals to create combined threats to crop safety and human health.
Impact of Biotic/Abiotic Stress Factors on Plant Specialized Metabolites
Not relevant to microplastics — this paper appears to examine how biotic and abiotic stress factors influence specialized metabolite production in plants; the available abstract is incomplete but contains no indication of microplastic relevance.
Unveiling the impact of microplastics and nanoplastics on vascular plants: A cellular metabolomic and transcriptomic review
This review summarizes how microplastics and nanoplastics affect plant health at the cellular and genetic level, disrupting metabolism, nutrient uptake, and growth in vascular plants. Since contaminated crops are a pathway for microplastics to enter the human diet, understanding how plants absorb and respond to these particles is important for food safety.
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.
Impact of nanoplastics uptake on modulation of plant metabolism and stress responses: a multi-omics perspective on remediation and tolerance mechanisms
Researchers reviewed how nanoplastics accumulate in plant tissues and disrupt metabolism, finding that these particles impair nutrient uptake, trigger reactive oxygen species overproduction, and alter gene and protein expression, while multi-omics approaches are revealing the molecular stress-response networks that plants use to tolerate or remediate nanoplastic contamination.
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.
[Physiological and Ecological Response Characteristics and Transcriptomic Change Characteristics of Rice （Oryza sativa）Under Different Microplastic Stresses].
Researchers used transcriptomic analysis to characterize physiological and ecological response characteristics of an aquatic organism exposed to microplastic stress, identifying gene expression changes in pathways related to immune function, oxidative stress, and energy metabolism.
Arabidopsis Transcription Factor WRKY45 Confers Cadmium Tolerance via Activating PCS1 and PCS2 Expression
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.
Unveiling the impacts of biodegradable microplastics on cadmium toxicity, translocation, transformation, and metabolome in lettuce
Researchers studied how biodegradable microplastics interact with cadmium contamination in lettuce and found that the combination worsened the toxic effects on plant growth compared to cadmium alone. The biodegradable plastics increased cadmium accumulation in the edible parts of the lettuce and altered how the metal was distributed within plant cells. The findings raise concerns about using biodegradable plastic mulch in soils already contaminated with heavy metals, as it may increase the amount of toxic metals that end up in food crops.

Researchers found that polyethylene microplastics in soil increased cadmium uptake in lettuce shoots by 51% under acid rain conditions, while decreasing arsenic accumulation by 48%. The microplastics altered soil bacteria and disrupted key metabolic pathways, suggesting that the combination of microplastic pollution and acid rain may change how toxic metals move from soil into our food crops.
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.
Impact of microplastic residues from polyurethane films on crop growth: Unraveling insights through transcriptomics and metabolomics analysis
Residual plastic films from coated fertilizers harmed wheat growth by disrupting energy metabolism in roots, with one type reducing plant height by nearly 25%. However, some bio-based polyester films triggered plant defense responses that offset the damage, suggesting that switching to certain biodegradable alternatives could reduce the microplastic-related risks to crop production and food safety.
Ecotoxicological Impacts of Microplastics and Cadmium Pollution on Wheat Seedlings
Researchers investigated the combined effects of polyethylene microplastics and cadmium on wheat seedlings and found that microplastics generally reduced the antioxidant enzyme response that cadmium alone would trigger.

Researchers examined how different types and sizes of microplastics interact with cadmium, a toxic heavy metal, to affect sorghum growth and soil microbes. They found that the combined pollution generally increased plant stress and cadmium uptake, with effects varying by plastic type, particle size, and concentration. The study also revealed that the pollution mixture significantly altered soil bacterial communities and key metabolic pathways involved in nutrient cycling.
Micro-/nano-plastics as vectors of heavy metals and stress response of ciliates using transcriptomic and metabolomic analyses
This study examined how polystyrene microplastics and nanoplastics interact with cadmium to affect single-celled marine organisms called ciliates. The combined exposure was more toxic than either pollutant alone, disrupting the organisms' metabolism and stress responses at the genetic level. The findings demonstrate that microplastics can make heavy metal pollution worse by carrying metals into cells, a concern for marine food web contamination that could ultimately affect seafood safety.
