摘要
通过对攀西地区典型采矿区、普通果园种植的5年龄芒果(即矿区芒果、普通芒果)中目标元素的检测分析,评估矿区环境对芒果品质的影响效应.以栽培品种“凯特”为例,对比分析不同种植区域芒果中砷、汞、铬、镉、铅、铜、锌、钙和镁等目标元素含量,借助单因子污染指数(Pi)、内梅罗综合污染指数(Pc)、危害商(HQi)和危害指数(HI)等标准,对芒果中目标元素可能造成的食品安全问题和健康风险进行评估.结果显示,矿区芒果中目标元素含量普遍高于普通芒果,镁质量分数(36.82±3.25 mg/kg)最高(n=5,P>0.05),钙质量分数(34.62±2.44 mg/kg)次之(n=5,P<0.01),汞质量分数(0.9±0.3μg/kg)最低(n=5,P>0.05);除铅质量分数(0.1079±0.0016 mg/kg)略高于国家限量标准(0.10 mg/kg)外,其余目标元素均未超标.在污染水平方面,除矿区芒果中单因子污染指数PPb(1.0790±0.0347>1.0)处于轻污染状态、内梅罗综合污染指数Pc(0.8221±0.0242>0.7)超过食物安全警戒线外,其余元素的Pi值、普通芒果的Pc值(0.5972±0.0137)均未超标(1.0、0.7),为未受污染或安全等级状态.在积累趋势方面,普通芒果中除Pb的生物积累系数(BAF)低于矿区芒果外,其余元素的BAF均大于矿区芒果.食物摄入健康风险评价结果表明,在相同芒果摄入量情况下,矿区芒果相较于普通芒果、儿童相较于成人更易产生健康风险.总体上,矿区芒果受污染程度高于普通芒果,且主要源于Pb污染;但其污染水平尚不足以诱发健康风险,可以安全食用.
This paper elucidates the effect of mining environment on the quality of mangoes by detecting and analyzing target elements in five years mangoes(i.e.mining mangoes and common mangoes)grown in typical mining areas and common orchard in the Panxi area.Using the cultivar"Keitt"as an example,comparative analysis of the target elements of arsenic(As),mercury(Hg),chromium(Cr),cadmium(Cd),lead(Pb),copper(Cu),zinc(Zn),calcium(Ca)and magnesium(Mg)in mangoes from different planting areas are put forward.The possible food safety problems and health risks caused by target elements in mangoes with the help of single factor pollution index(Pi),Nemero comprehensive pollution index(Pc),hazard quotient(HQi)and hazard index(HI)are assessed.The content of target elements in mining mangoes is generally higher than those in common mangoes,with Mg content(36.82±3.25 mg/kg)being the highest(n=5,P>0.05),Ca content(34.62±2.44 mg/kg)the second highest(n=5,P<0.01)and Hg content(0.9±0.3μg/kg)the lowest(n=5,P>0.05),except for the Pb content(0.1079±0.0016 mg/kg),which is slightly higher than the national limit standard(0.10 mg/kg),the rest of the target elements do not exceed the limit standard.In terms of the pollution levels of the target elements,except for the single factor pollution index PPb(1.0790±0.0347>1.0)in the mining mangoes,which is in a lightly polluted state,and the Nemero comprehensive pollution index Pc(0.8221±0.0242>0.7),which exceeds the food safety alert level,the Pi values of the remaining elements and the Pc values(0.5972±0.0137)of common mangoes do not exceed the limit(1.0,0.7),and they are in an unpolluted or safe state.Regarding the accumulation trend of the target elements,the BAF values of all elements are greater than those of the mining mangoes,except for the bioaccumulation factor(BAF)of Pb in common mangoes,which is lower than that of the mining mangoes.The results of the health risk assessment of food intake showed that:for the same amount of mango intake,the mining mangoes are more likely to pose a he
