)摘要:现场信号瞬时值考察和研究室ICP-MS尺度,

讨论福建省长汀县稀土矿区蔬菜地壤和首要蔬菜中强敌的目录又评价蔬菜包入球中对人体可能性发生的康健风险。水果揭晓,,Cd在蔬菜壤、Cu和作为

两个很的壤周围的品质基准,平均估价超越基准10.71,1.12,0.29倍。强敌在壤击中要害潜在生态风险说明者

373.66,在潜在生态风险程度上。蔬菜首要由强敌镉污点,

与食品卫生基准值的比得上,超越基准10.926。,1.016倍。蔬菜击中要害强敌和井水的包入球中可能性会形成、Cd and Pb

,度为>Cd>P

b,关心部门要注意到。强敌对小孩的康健形成的风险不同高于。蔬菜稀土重新获得拆移吸取和整理较大。,褊狭的的农夫应该是独一与植物的叶子低整理的有理选择,以

蒸发强敌对人体康健的为害。

ian350007)Abstract:Concentrations and health risk assessments of heavy 

metals in cultivation soils and vegetables accumulationfrom REEs mining area of Changting county 

of Fujian province were studied based on field systematic sampling.Thecultivation soils were contaminated seriously by heavy metals,especially Cd,Cu and As,exceeding 

10.71,1.12,0.29times higher than the National Soil Quality 

Standard-GradeⅡ;the potential ecological risk index of soilswas 373.66,which had extremely 

potential ecological risk.The concentrations of Cd and As in vegetableswere 10.926,1.016times hig

her than those of the maximum levels of contaminants in foods.The order ofindividual risk index for the health of adult and children was As>Cd>Pb,in which As had an extremely

high risk.Moreover,children were more sensitively affected by heavy 

metals from vegetables ingestion,therefore,attention should be paid to children’s health monitoring 

in such area.Most of vegetables ofmining area had great capacities of uptake and accumulation heavy 

metals,therefore local farmers shouldchoose appropriate vegetables of low accumulation heavy metals for reducing 

health risk effectiveness.Key
