Of 174 cattle dipped in an emulsified preparation of benzene hexachloride labeled for plant use, 18 were fatally poisoned. The preparation contained 0.14% active ingredient, gamma isomer of benzene hexachloride (BHC), a normally safe concentration for cattle. Analyses revealed 0.08% gamma BHC in the used dip and 0.5, 7.9, and 198 ppm in liver, kidney, and hairskin specimens, respectively, from a fatally affected cow. Microscopic examination of the freshly prepared dip demonstrated emulsion droplets ranging from 5 to 60 mu in diameter.
在174头浸泡于一种标为用于植物的六氯苯乳化制剂中的牛中，有18头发生致命中毒。该制剂含有0.14%的活性成分，即六氯苯（BHC）的γ异构体，这对牛来说通常是安全浓度。分析显示，使用过的浸泡液中γ - BHC含量为0.08%，一头致死牛的肝脏、肾脏和毛发皮肤标本中分别为0.5 ppm、7.9 ppm和198 ppm。对新制备的浸泡液进行显微镜检查发现，乳液滴直径在5至60微米之间。
