Impact of Microplstic and Lead Toxicity on the Terrestrial Plants: a Critical Review
Summary
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.
Microplastics pollution is a growing delinquent concern globally, as it is widely used at present on daily basis such as cutlery, commercial packaging, building insulation, medical equipment, toys, and other items used in the food sector.Environmental pollution of microplastics known to be mediated anthropogenically which is now becoming toxic to humans, animals and plants.Microplastics (<5mm) are responsible for uptake of potentially toxic elements in the soil which are responsible for many changes like physiochemical characteristics including enzymatic activity, plant growth and yield.One of the most perilous heavy metals that interfere with plant growth and development is the lead (Pb).Previous research showed that growing Pb concentrations in plants had an unfavourable effect on root, shoot, and new biomass, leaf growth development, and growth tolerance index.This review paper investigates the synergistic effects of microplastics and lead toxicity on plant.This review also highlights the possible environmental consequences by microplastics and lead contamination.

Combined Phytotoxicity of Microplastics andLead on the Growth and Physio-BiochemicalCharacteristics of Tobacco (Nicotiana tabacum)
Researchers grew tobacco plants in soil contaminated with both polyethylene microplastics and lead, finding that the combination caused greater damage to photosynthesis and plant growth than either pollutant alone, while microplastics partially reduced how much lead roots absorbed. The study shows that microplastic and heavy metal co-contamination — increasingly common in agricultural soils — poses compounding risks to crop health.
An Impact Of Microplastic And Microplastic + Lead Induced Toxicity On Growth Parameters And Chlorophyll Content Of Tomato Plant: (Comparison Study)
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.
Effects of polypropylene microplastics and lead (Pb) contamination on soil properties and the growth response of Ficus Benjamina
Researchers found that polypropylene microplastics and lead contamination together cause greater harm to soil chemistry and plant growth than either contaminant alone, with Ficus plants showing significantly reduced leaf area, root length, and total biomass when exposed to both. Microplastics also lowered soil pH and depleted essential nutrients, compounding the toxic effects of the heavy metal.
Coexistence of microplastics and heavy metals in soil: Occurrence, transport, key interactions and effect on plants
This review examines how microplastics and heavy metals like lead, cadmium, and arsenic interact in soil, often creating combined toxic effects on plants that differ from either pollutant alone. These interactions are relevant to human health because contaminated crops can transfer both microplastics and heavy metals to people through the food supply.
Effects of combined microplastics and heavy metals pollution on terrestrial plants and rhizosphere environment: A review
This review summarizes how microplastics and heavy metals interact in soil to affect plant growth and the surrounding ecosystem. When present together, these pollutants cause significantly more harm than either alone, reducing plant weight by up to 87.5% and altering how heavy metals accumulate in crops -- raising concerns about food safety and human exposure through contaminated agricultural products.
