1 水产品药物残留的原因1.1 滥用渔药 很多养殖生产者无病不设防,有病滥用药,盲目增加用药量现象极为普遍。如福尔马林的消毒浓度由每立方米水体几十克增加到数百克,抗生素等药物的消毒用量从每立方米水体儿克增加到十儿克。这不仅使养殖种类产生了抗药性,增加了病害防治的难度,也直接给养殖对象造成药源性损伤,形成新的药源性病害,导致了不得不再次大量施药的恶性循环,加大了养殖对象体内的药物残留量。
1 aquatic drugs cause of drug residues 1.1 Abuse of fishery Many aquaculture producers disease-free and undefended, ill drug abuse, blindly increasing the amount of medication is extremely common. For example, the disinfection concentration of formalin is increased from several tens of grams per cubic meter of water to several hundred grams. The disinfection rate of antibiotics and other drugs is increased from 10 grams per cubic meter of water to 10 grams. This not only makes the breeding species have a resistance, increasing the difficulty of disease prevention, but also directly to the breeding objects caused by drug-induced damage, the formation of new drug-induced diseases, leading to a vicious cycle had to re-apply a large number of drugs, increase Reproduction of drug residues in the body.
