| Citrus at home and abroad Maximum residue limits of pesticides
Standards, a rough division of the citrus varieties,tory burch shoes, and more direct reference to the CAC's standards, failed to fully consider the specific varieties of good agricultural practices, there is no specific assessment of pesticide risk analysis, it is difficult to play in international trade technology The role of barriers, import and export citrus to China will have an impact. Therefore, our standard of pesticide residue in agricultural development, not only to consider the production and security, but also to consider the trade, market, and many other factors, make it play a role in international trade. 4.4 The lack of detection methods, detection technology has been relatively slow to allow 550 of the 291 pesticides used on crops, but the new maximum residue limits of pesticides issued by the type of pesticide involved only 136 species, of which only involves citrus 49 species, and some commonly used fungicides, such as mancozeb and extensive use of new pesticides such as imidacloprid, abamectin, fipronil and so does not require detection method. In addition, even though China has also developed using GC-MS, LC-MS methods such as method of pesticide residue standards, but because of expensive equipment, the penetration rate is low, only a handful of research, teaching and testing organizations can apply these advanced methods testing, and testing organizations at the grassroots level, due to financial, technical, personnel, and many lack, still only using gas chromatography, liquid chromatography, colorimetry,tory burch shoes sale, etc. or even detection, detection limit, sensitivity, precision and so on up less than the relevant standards. 5 Strategies 5.1 pesticide residues to strengthen basic research, to accelerate the manufacturing of pesticide residue standards (revision) of raw agricultural products are citrus (RawAgriculturalCommodity, RAC), the maximum residue limits of pesticide residues in the formulation,tory burch handbags, at least three aspects: toxicological information, enter the body through the diet daily volume and the degradation of residual contaminants in agricultural products and distribution [61. Hence the need to strengthen risk assessment, scientific and reliable information on pesticide risk assessment data as a technical support, development of indicators of pesticide residue limits. 2007l of modern scientific instruments can be found by comparing the developed system of pesticide residues limits (Amendment) to provide faster and more strict index value, the other hand, the slower of the update. Therefore,tory burch reva, we should strengthen the pesticide residues in citrus fruits such as pollution monitoring and risk assessment, and other infrastructure work and speed up the standard system (revising) the pace of resolving international trade disputes as to provide a scientific basis. 5.2 be familiar with and integration of international advanced standards for technical and economic reasons, countries set limits between the quite different circumstances,tory burch sandals, CAC standards in international food trade because of its effectiveness and practicality, has gradually evolved into the international community widely accepted and commonly used in food safety management measures, the international food trade in a disguised form of mandatory standards. Therefore, standardization of laws and regulations in line with China under the premise of the standard system and learn from foreign advanced analytical methods to use the main CAC index of pesticide residues, supplemented by standards of developed countries, at this stage to improve the standard of pesticide residues in citrus the level of pesticide residues in the main breakthrough in an effective way of technical barriers to trade. 5.3 Science and Technology aimed at the forefront of efforts to improve the detection technology currently used in citrus and other agricultural products more and more pesticides, pesticide residues and more complex components, testing of pesticide residue standards and technology have become increasingly demanding. Japan, the European Union, detection of pesticide residue limits, is to trace, ultra volume and direction to multiple residues, and the current testing technology to stand-alone testing of the majority, while multi-residue detection technology behind. Therefore, we must closely follow the international developments of advanced detection technology to continuously improve the detection, testing for the development of a scientific and reasonable technical standards to provide reliable protection.
