摘　　要：目的调查2018—2019年宝鸡市4个县农田土壤和地产水果中铅、铬和镉的含量,并展开污染评价。方法以2018—2019年从宝鸡市4个县的农贸市场和超市等地购买的122份地产水果为分析对象,并采集120份土壤,采用原子吸收和电感耦合等离子体质谱法进行检测分析。结果眉县农田土中镉超标率为60%,为轻度污染;地产水果中各元素无超标,为安全清洁;各元素的的富集系数镉(0.004 5)>铅(0.001 3)>铬(0.000 4);眉县土壤和地产水果中铅含量呈正关性(P<0.05)。结论 2018—2019年宝鸡市4个县农田土壤中镉污染严重,其中眉县土壤中镉污染问题尤为突出,有关部门应当加强预防和治理。Objective To investigate the contents of lead,chromium and cadmium in farmland soil and local fruit in four counties of Baoji City from 2018-2019,carry out the pollution assessment. Methods Totally 122 samples of local fruits were purchased from farmers’ markets and supermarkets in four counties,and 120 soil samples were collected. The detection and analysis were performed by the atomic absorption and inductively coupled plasma mass spectrometry. Results The exceeding standard rate of cadmium in farmland soil was 60%,which was mild pollution. The elements in local fruits met the standards,which were safe and clean. The the enrichment coefficient of elements was cadmium(0.004 5)>lead(0.001 3)>chromium(0.000 4). There was a positive correlation between lead in soil and fruits of Meixian County. Conclusion The cadmium pollution in farmland soil in four counties of Baoji city from 2018-2019 is serious,especially the cadmium pollution in soil of Meixian County,and relevant departments should strengthen prevention and control.
