Abstract:Demonstrate significant heavymetal contamination risks predominantly fromatmospheric sedimentation,agro chemicalapplications,and industrialpolution,etc.Comparedwithothervegetabletaxa,leafyegetables haveasigificantlyelevatedbio-accumulationofheavymetals.Itiscrucial forreducing suchcontaminationriskstoelucidating theabsorption,accumulation,and enrichment paterns of heavy metals in leafy vegetables,coupled with developing targeted phytoremediationstrategies againstcontamination.Whileextensiveresearch has beenconductedacrossglobalagricultural systemsonpoint-source heavy metalcontamination inleafyvegetables,investigations into non-point sourcepolution mechanisms and associated human health risk assessments remain significantly understudied.Acomprehensive review andanalysisoftheliteratureonheavy metalpolutioninmajorvegetablesandleafyvegetables,both domesticand internationalwasconducted.Theheavymetalpolution situationsof diferentvegetable types werecompared.It wasrevealed thatleafyvegetables weresubject tothemost severe heavy metalpollution,and there were marked inter-species divergence inheavy metal polltion among diferent kindsofleafyvegetables.To address heavy metalcontamination in leafy vegetables,strategiccultivationinlow-contamination farmlands isadvised.Research should prioritize elucidatingcontamination dynamics inopen-field versus facility-grown systems,whileconcurrentlyselecting low-accumulation cultivars andimplementing tailored agronomic practices.This integratedapproach efectivelyreduces contaminantlevels andestablishes a scientific framework for risk mitigation.
