由于工农业的大跃进,滴滴悌和六六六的使用范围愈来愈广。但是如果使用不慎或管理制度不严也会带来一些问题,如误食了含有滴滴悌或六六六的蔬菜和粮食就会发生食物中毒。为了予防上述食物中毒一方面加强使用管理制度,另一方面对所疑食物进行检验。食物中滴淌悌和六六六的定性检查,一般都是先用有机溶剂提取,其残渣用硝化反应(滴滴悌)碱性溶液中脱氯化氢(滴滴悌和六六六)和镜检其结晶(六六六),但上述方法需要较好的设备和技术较熟练的化验人员,不易在广大农村推广使用。下面介绍一个简易方法。
Due to the great leap forward in agriculture and industry, the scope of use of Drips and Sixty-Six is getting wider and wider. However, some problems may arise if carelessness is imposed or the management system is not strict. Food poisoning may occur if vegetables and grains containing drops of Dili or BHC are consumed. In order to prevent the above-mentioned food poisoning on the one hand to strengthen the use of management systems, on the other hand the suspect food inspection. Dripping dripping food and six hundred sixty-six qualitative inspection, are generally first extracted with organic solvents, the residue with nitration reaction (Drip) alkaline solution dehydrochlorination (Drip and BHC) and microscopic examination Its crystallization (666), but the above methods require better equipment and technology more skilled laboratory personnel, not easy to promote the use of the vast rural areas. Here’s a simple way.
