ClearEffects of microplastics and biochar on soil cadmium availability and wheat plant performance
Researchers found that fresh microplastics increased soil cadmium availability and plant uptake in wheat, and when combined with biochar, microplastics further amplified cadmium mobilization by decreasing soil pH and increasing dissolved organic matter, complicating biochar-based soil remediation strategies.
Effects of microplastics in soil on the regulation of cadmium bioavailability by biochar
Researchers investigated how biochar amendments affect cadmium bioavailability in soils co-contaminated with microplastics, finding that the presence of microplastics altered cadmium mobility and complicated biochar's remediation effectiveness in ways that depend on the specific MP type present.
Biochar Offsets Microplastic-Induced Cadmium Mobilization and Plant Accumulation in Contaminated Soils
This greenhouse study found that microplastics in soil can increase how much cadmium (a toxic heavy metal) is absorbed by crops. Adding biochar to the soil helped counteract this effect, reducing cadmium uptake by plants — a promising finding for protecting food safety in contaminated farmland.
Competitive adsorption behaviors and mechanisms of Cd, Ni, and Cu by biochar when coexisting with microplastics under single, binary, and ternary systems
Researchers studied how biochar absorbs heavy metals like cadmium, nickel, and copper when microplastics are also present in the soil. They found that microplastics competed with biochar for metal binding, reducing its effectiveness as a soil amendment. The study suggests that microplastic contamination in agricultural soils may undermine common remediation strategies that rely on biochar to immobilize toxic metals.
Adsorption, immobilization mechanisms and potential risks of Cd in soil-biochar-microplastics system
This study examined how varying concentrations (0-10%) of polyethylene microplastics affect biochar's capacity to adsorb and immobilize cadmium (Cd) in soil. Microplastics increased biochar's Cd adsorption by up to 33% but simultaneously elevated Cd leaching risk, highlighting a complex trade-off in using biochar for heavy metal remediation in microplastic-contaminated soils.
Biodegradable microplastics coupled with biochar enhance Cd chelation and reduce Cd accumulation in Chinese cabbage
Researchers tested how biodegradable polylactic acid (PLA) microplastics interact with biochar in soil contaminated with cadmium, a toxic heavy metal, and found that the combination reduced cadmium uptake in Chinese cabbage by up to 47%. The PLA promoted formation of natural chelating compounds in the root zone that bound the cadmium, suggesting a possible soil remediation benefit from certain biodegradable plastics.
Combined Effects of Polyethylene Microplastics and Biochar on Chlorophyll Content in Wheat (Triticum aestivum)
Researchers grew wheat seedlings over 21 days in soils containing polyethylene microplastics and wood biochar, individually and in combination, and measured chlorophyll content as an indicator of plant health. Biochar partially mitigated microplastic-induced reductions in chlorophyll, suggesting that carbon amendment could serve as a low-cost strategy to protect crops in microplastic-contaminated soils.
Evaluating the Role of Tobacco Stalk Biochar in Wheat Growth Under Microplastic Exposure
Researchers conducted a two-factor pot experiment testing whether tobacco stalk biochar could mitigate the effects of polyethylene microplastics on wheat growth, finding that biochar addition restored soil pH and organic matter and partly reversed the physiological stress caused by microplastic exposure.
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.
Remediation of Coastal Wetland Soils Co-Contaminated with Microplastics and Cadmium Using Spartina alterniflora Biochar: Soil Quality, Microbial Communities, and Plant Growth Responses
Researchers tested whether Spartina alterniflora-derived biochar applied at 2% could remediate coastal wetland soils co-contaminated with cadmium and polyethylene or polylactic acid microplastics. Biochar significantly improved soil pH, organic matter, and microbial diversity while reducing cadmium bioavailability and plant uptake, making it a promising amendment for combined metal-plastic contaminated soils.
Effects of Co-Contamination of Microplastics and Cd on Plant Growth and Cd Accumulation
Researchers investigated how two types of microplastics, high-density polyethylene and polystyrene, at various concentrations affect cadmium uptake and toxicity in maize plants grown in agricultural soil. The study found that while polyethylene alone had no significant effect, polystyrene at higher doses altered cadmium accumulation patterns, suggesting that different plastic types may interact differently with heavy metals in soil.
Impact mechanisms of polyethylene microplastic on Cd adsorption and passivation by KMnO4-modified biochar in different soils
Researchers investigated how polyethylene microplastics affect cadmium (Cd) adsorption and passivation by KMnO4-modified biochar across 50 soil combinations varying in soil type, Cd concentration, and microplastic content. Microplastics increased biochar's Cd adsorption capacity by 1.5-33.1% depending on concentration but also increased Cd leaching risk at higher microplastic loads.

Researchers tested how different microplastic types combined with cadmium affect plant growth and soil health. Aged and biodegradable microplastics increased cadmium uptake in mustard greens more than fresh conventional plastics did. The study also found that microplastics altered soil microbial activity, suggesting that plastic pollution in farmland could change how plants absorb toxic metals from contaminated soil.

The results suggest biochar could be a practical tool for managing farmland affected by plastic pollution.
Plant Cadmium Toxicity and Biomarkers Are Differentially Modulated by Degradable and Nondegradable Microplastics in Soil
Researchers compared how degradable (polylactic acid) and nondegradable (polypropylene) microplastics affect cadmium toxicity in plants grown in contaminated soil. They found that polypropylene caused greater root growth inhibition, while polylactic acid led to higher levels of cellular stress markers at certain concentrations. The study reveals that both types of microplastics can alter soil chemistry and increase the uptake of heavy metals by crops, but through different mechanisms.
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. The study also found that microplastics altered cadmium bioaccumulation patterns, increasing cadmium uptake in roots at low concentrations but decreasing it at higher levels, suggesting complex interactions between these co-occurring pollutants.

Researchers investigated how cadmium and chemical compounds that leach from microplastics jointly affect wheat seed germination and seedling growth. They found that microplastic leachates from PVC and polyethylene can interact with cadmium in complex ways, sometimes worsening and sometimes lessening the toxic effects on young wheat plants. The study suggests that the combined presence of heavy metals and microplastics in agricultural soils could pose risks to crop development.
