目的:分析蔬菜汞检出及含量情况和污染原因,提供防治汞污染科学依据。方法:在10个县(市)、区,各采集蔬菜3至6份,进行汞含量检测分析。结果:采集检测蔬菜59份,检出含汞蔬菜48份,检出率为81.36%,检出超标蔬菜6份,超标率为10.17%。城市、农村蔬菜汞检出率差别无显著性(x2=0.104,P=0.747),超标率也无显著意义(x2=0.241P=0.624),不同种类蔬菜汞检出率差别无显著性意义(x2=5.805,P=0.121),超标率差别也无无显著性意义(x2=2.508,P=0.474)。结论:蔬菜汞污染情况较为严重,要制定严格和行之有效的减排标准和政策,压低工矿企业生产及社会活动向大气中汞的排放量,改进农业生产技术,科学施用化肥、农药,最大限度控制汞对环境、食品的污染,保护广大人民群众健康。
Objective: To analyze the detection and content of mercury in vegetables and the causes of pollution, and to provide a scientific basis for prevention and control of mercury pollution. Methods: Three to six samples of vegetables were collected from 10 counties (cities) and districts, and mercury content was detected and analyzed. Results: 59 samples of vegetables were collected and 48 samples of mercury-containing vegetables were detected. The detection rate was 81.36%. 6 samples of over-standard vegetables were detected. The over-standard rate was 10.17%. The detection rate of mercury in urban vegetables and rural vegetables was insignificant (x2 = 0.104, P = 0.747), and there was no significant difference between the two standards (x2 = 0.241P = 0.624). There was no significant difference in mercury detection rates between different vegetables x2 = 5.805, P = 0.121). There was no significant difference between the two groups (x2 = 2.508, P = 0.474). Conclusion: The vegetable mercury pollution is more serious. It is necessary to formulate strict and effective emission reduction standards and policies to reduce mercury emissions to the atmosphere from the production and social activities of industrial and mining enterprises, to improve agricultural production technology, to apply chemical fertilizers and pesticides scientifically Limit the control of mercury pollution of the environment, food, protect the general public health.
