EU will re-set toxicity standards for pesticides
China Drying Network News Recently, the European Food Safety Authority (EFSA) announced that at present, under the conditions of using low concentrations of active ingredients, nicotine insecticides such as imidacloprid and thiamethoxam have no sufficient data on the survival of bee populations. Support, need to reset the toxicity criteria. EFSA requires professional committees to carry out in-depth review of products such as canidin, thiamethoxam, imidacloprid, acetamiprid, and thiacloprid. The investigation report is expected to be released in December. EFSA is based on research reports published by two research groups in France and Britain in March this year. The study data showed that the residual levels of nicotine pesticides in nectar were significantly lower than those approved by the institutions, while the bee's lethal dose during indoor testing was greater than under actual conditions. The research reports were based on the effects of imidacloprid and thiamethoxam on bees. These pesticides can indirectly interrupt the foraging activities of bee populations and produce certain toxic effects on the population. The results of this study prompted some EU member states to call for a re-evaluation of neonicotinoid insecticides. At the same time, the European Union also requires EFSA to strengthen the influence of nicotinic insecticides on the survival of bee populations to determine whether they are used through seed treatments. In addition to these two studies, EFSA also reviewed a German study that showed that imidacloprid and clothianidin have an impact on the survival of honeybee populations. EFSA stated that in the determination of nectar residues, three indicators of neonicotinoid insecticide exceeded the maximum residue level specified. Tests have shown that exposure to simulated test methods may have a greater impact than bees in reality. Therefore, when formulating relevant standards, different exposure levels must be considered to ensure that the test results are close to the actual situation.
High strength steel tie rod are steel structural members made of carbon structural steel and alloy steel, processed by machining, heat treatment and surface anti-corrosion treatment, supplemented by adjusting sleeves, lock and joints etc. The steel tie rod are important components of steel structures for construction of giant, large span buildings and ship docks. They are mainly used for prestressed parts and large span buildings in construction projects. While the strength of the product is improved, but the plasticity index is not reduced, which satisfies the principle of using the same amount of strength in the architectural design. The tie rods, tie bars, tension rods and tension bars steel grades are specified as grade 460, grade 520, grade 550, grade 650, grade 785, grade 830, grade 930, grade 1080 etc.
