摘要
目的:确定辣椒中危害物的风险等级,并结合时空视角剖析辣椒中危害物的不合格情况,得出辣椒中风险等级高的危害物,对高效监管辣椒安全提出意见。方法:为评估辣椒中风险物风险值,本文采用熵值法计算风险大小,并利用二八原则,对风险大小进行等级排序。为对辣椒风险物进行时空分析,利用描述性统计方法进行统计描述,利用全局与局部自相关分析方法分析辣椒中危害物风险等级高以及较高风险物的全国空间分布规律。结果:辣椒中镉、铅、铬、硫丹、克百威和久效磷是高风险物质。2016—2020年,全国辣椒不合格率变化趋势稳定,其中湖北省辣椒不合格率最高,抽样场所中辣椒不合格主要发生在超市和农贸市场。结论:辣椒风险物分级结果,可提高政府监管效率,同时为企业自我管理提供参考。
Objective:To ensure the risk level of hazardous substances in chili pepper,and analyze the unqualified situation of hazardous substances in chili pepper by combing spatial with temporal perspectives.Finally,by acquiring high-risk substances in chili pepper,and providing suggestions for efficient supervision of chili pepper safety.Methods:To evaluate the risk value of risk substances in chili pepper,the entropy method was used to calculate the risk level,and the 28 principles were used to classify and rank the risk level.In order to conduct spatiotemporal analysis of the risk substances in chili pepper,descriptive statistical methods were used for statistical description to conduct spatiotemporal analysis of the risks.Global and local autocorrelation analysis methods were used to analyze and explore the national spatial distribution patterns of high risk and high-risk substances in chili pepper.Results:Cadmium,lead,chromium,endosulfan,carbofuran and monocrotophos were high-risk substances in chili pepper;the overall change in the failure rate of chili pepper was stable from 2016—2020,and the failure rate of chili pepper in Hubei was the highest among the national provinces,and the failure of chili pepper in sampling places mainly occurs in supermarkets and farmers'markets.Conclusion:The classification results of chili pepper risk substances could improve the efficiency of government supervision,while providing a reference for enterprise self-regulation.
