美国EPA农药登记残留试验中样品储藏稳定性试验 总被引:1,自引:0,他引:1
<正>农药残留稳定性数据在农药登记残留试验中占有重要地位,由于残留试验样品采收后会在冰箱中存放较长时间,因此,样品储藏期间农药在样品中的稳定性研究对农药残留检测结果判定具有重要意义。我国一直缺少此方面的规定,导致农药残留基础研究数据缺乏,现翻译美国EPA农药登记残留样品储藏稳定性试验准则,供读者参考。OPPTS 860.1380样品储藏稳定性数据1范围1.1适用性该导则的目的是满足联邦杀虫 相似文献

欧洲委员会和各成员国正在研究考虑简化欧盟审批使用在小作物上的农药登记资料要求的建议。英国农药安全局(PSD)代表欧洲委员会准备的报告中提出,为减少农药在小作物上登记所需的补充试验数据,可以参考现有的农药在主要作物上的登记资料(包括药效、作物安全和残留数据)。由于欧 相似文献

本文简要介绍了日本推进小宗作物农药登记的法律背景和扩大小宗作物农药登记的主要对策,包括减少登记试验数、作物分类登记、设立经过措置和中央地方联合推进体制等,以期为我国小宗作物农药登记工作提供借鉴。 相似文献

为评估山西省杏中的农药残留水平,建立超高效液相色谱-串联质谱(UPLC-MS/MS)测定杏中吡虫啉、苯醚甲环唑等29种农药的分析方法,并对杏中的残留量进行分析。结果表明:29种农药在0.001~0.2 mg/kg范围内线性关系良好,决定系数R 2 > 0.99;在0.005、0.1和1 mg/kg 3个添加水平下,平均回收率为63%~117%,相对标准偏差(RSD)为0.7%~7.7%;定量限(LOQ)为0.005 mg/kg,符合农药多残留分析要求。采用所建立的方法对山西省采集的42个杏样品进行分析,结果表明:42个杏样品中有26个检出农药,检出率为61.9%,其中吡虫啉检出率最高(45.2%);样品检出残留量在< 0.005~0.57 mg/kg之间。共检出13种农药,在杏上均未登记,表明作为一种特色小宗作物,杏中病虫害防治存在无药可用和无标可依等问题,影响农产品安全。通过对比国内外杏中有关农药残留限量标准建设情况,建议我国相关部门加强监管,对氰霜唑、氟环唑、乙螨唑、多效唑和哒螨灵5种农药进一步考察制定其残留限量的必要性和可行性。 相似文献

Abstract An online information system was developed to allow US growers to search pesticide application information for export of vegetables and fruits. By entering an export country, a crop name, pesticide type, and post harvest interval, a user can obtain a list of pesticides labeled for the crop, the pesticides suitable for use with export, and the associated pesticide application restriction (PAR) information for each pesticide in the recommended list. A relational database (Microsoft SQL Server 2000) was used to house the PAR data, pesticide labels, and pesticide maximum residue limit information (MRL). These data were obtained from governmental agencies and international organizations. The data were then entered into the system using an online data entry system developed using ColdFusion programming language. The database currently contains the registration information for over 1,100 pesticides, 20,000 MRL data entries, and 20,000 PAR entries. New data are updated frequently. The project web site is http://cipm.ncsu.edu/exportMRL. 相似文献

通过对农药厂周围土壤和农作物中乙草胺含量的测定,研究了乙草胺农药厂对其周边环境的污染情况。从距离农药厂100 m以内15个点共取得73份样品,采用气相色谱法测定了土壤及农作物样品中乙草胺的残留量。结果显示:农药厂南面土壤及农作物中乙草胺的平均检出量分别为38.2~45.3 μg/kg和39.5~46.0 μg/kg,东面分别为15.4~22.9 μg/kg和21.6~30.1 μg/kg;耕作区土壤污染状况在垂直方向及不同距离上均未表现出明显的差异性;东面及南面土壤与农作物中污染情况分别存在对应关系。农作物样品中乙草胺的平均检出量为21.6~46.0 μg/kg,表明该区域生产的农产品存在一定的安全风险。 相似文献

Common voles (Microtus arvalis) are common small mammals in some European landscapes. They can be a major rodent pest in European agriculture and they are also a representative generic focal small herbivorous mammal species used in risk assessment for plant protection products. In this paper, common vole population dynamics, habitat and food preferences, pest potential and use of the common vole as a model small wild mammal species in the risk assessment process are reviewed. Common voles are a component of agroecosystems in many parts of Europe, inhabiting agricultural areas (secondary habitats) when the carrying capacity of primary grassland habitats is exceeded. Colonisation of secondary habitats occurs during multiannual outbreaks, when population sizes can exceed 1000 individuals ha?1. In such cases, in‐crop common vole population control management has been practised to avoid significant crop damage. The species' status as a crop pest, high fecundity, resilience to disturbance and intermittent colonisation of crop habitats are important characteristics that should be reflected in risk assessment. Based on the information provided in the scientific literature, it seems justified to modify elements of the current risk assessment scheme for plant protection products, including the use of realistic food intake rates, reduced assessment factors or the use of alternativee focal rodent species in particular European regions. Some of these adjustments are already being applied in some EU member states. Therefore, it seems reasonable consistently to apply such pragmatic and realistic approaches in risk assessments for plant protection products across the EU. © 2013 Society of Chemical Industry 相似文献
