鳃是六六六进入鱼体的主要通道,鱼体的残留水平决定于水与体脂间的分配平衡。要使背肌六六六残留低于0.5毫克/公斤,则水中六六六含量要低于0.024毫克/升。鱼体六六六残留向水体释放的速度与温度有关,温度低,释放慢;当温度低于10℃时,释放的速度极慢以至难以检出。建议采用清水寄养的方法,让鱼体释放六六六,降低残毒,提高商品质量。这种方法估计也适用于其它脂溶性的与水分配系数不是太大的污染物。
The gills are the main passageway into the fish body. The residual level of fish body depends on the balance of water and body fat distribution. To make the back muscle BHC residues less than 0.5 mg / kg, the water content of BHC is less than 0.024 mg / liter. Released to the body of the six-six fish residue velocity and temperature-related, low temperature, slow release; when the temperature is below 10 ℃, the release rate is very slow and even difficult to detect. Proposed water foster care method, so that the release of six six six fish, reduce residue, improve product quality. This method is also estimated to be applicable to other fat-soluble contaminants with a water partition coefficient not too high.
