Composition Features and Health Risk Assessment of REEs in Typical Produce with Soil Heavy Metal Excess in Western Zhejiang,China
摘要
Abstract
In the farmlands with heavy metal excess,the safety of produce is of great concern.In order to systematically study the content of rare earth elements(REEs)in the typical produce with excessive heavy metals in western Zhejiang and their influence on human health,the samples of produce such as green vegetables,white radish,rape and pomelo are collected and analyzed in the concentrated areas of farmlands where heavy metals exceed the standard,and the contents of the main heavy metals(Cd,Hg,As,Cu,Zn,and Ni)and 16 rare earth elements are also analyzed.The results show that the situation about the heavy metals in the produce exceeding the standards is quite serious.The exceeding rate of Cd content in the pomelo samples is 14.28%,and the exceeding rates of As,Cd,and Hg contents in the white radish samples are 33.33%,22.22%and 11.11%respectively,while the exceeding rates of As and Cd contents in the rape samples are both 33.33%.The total rare earth content in the vegetable samples ranges from 3264.00 to 5553.15μg/kg,The REE content of the white radishs is the highest,the rape is of the second REE contents,and green vegetables are of the lowest REE contents.In contrast,the total rare earth content of the pomelo is only 449.51μg/kg,much lower than vegetables.The correlation analysis indicates the content of total rare earth elements,light rare earth and heavy rare earth in produce are significantly correlated with heavy metals as a whole,showing a synchronous increasing trend,it reflects that we should consider synthetically the enrichment synergy of the both(REEs and heavy metals)of the produce in the later soil remediation process.The average daily intake of rare earth elements by residents through eating these produce is 8.01μg/(kg·d)with the maximum daily intake of 17.67μg/(kg·d),the both are well below unsafe and subclinically damaging doses.This indicates that the health risks to REEs from daily produce intake in the study area are acceptable.关键词
