多氯联苯是一种剧毒高残留的污染物。它是200多种氯代芳香烃的总称,由于多氯联苯具有化学性质稳定、脂溶性强、绝缘性好、耐腐蚀、不易燃、电解常数高等优点,因而广泛用作变压器、电容器等设备的绝缘油和热载体,以及润滑油,涂料,无碳纸,增塑剂等的添加剂。我单位在70年代初,用西北某厂生产的多氯联苯作电容器,由于时间过长,外包装损坏,引起两例变电工中毒。现报告如下: 例一,陈××,女性,35岁,变电所工人,因头痛头晕,心慌胸闷,恶心,呼吸不畅,周身无力,失眠,饮食欠佳,于85年7月16日就医,当时面容灰暗,眼,口唇青紫,口腔周围粘膜、牙齿均为灰紫色,面部及暴露部位皮肤有散在的小丘疹,两手轻颤,指甲青紫并有白色小斑点,体温正常,血压96/60mmHg,心律齐,心率100次/分,无杂音;肺(一),肝肋下45cm、质软,无压痛,化验室检 PCBs are a highly toxic and highly contaminated residue. It is the general term for more than 200 kinds of chlorinated aromatic hydrocarbons. PCBs are widely used as transformers, capacitors and other equipment due to their chemical stability, strong fat solubility, good insulation, corrosion resistance, nonflammability and high electrolytic constant Insulating oil and heat carrier, as well as lubricants, coatings, carbon-free paper, plasticizers and other additives. My unit in the early 70s, with a factory in Northwest PCBs as capacitors, due to the time is too long, damaged packaging, causing two cases of substandard poisoning. The report is as follows: Example 1: Chen × ×, female, 35 years old, substation worker, dizzy due to headache, palpitation and chest tightness, nausea, poor breathing, exhaustion, insomnia, poor diet, on July 16, Seeing medical treatment, the face was gray, eyes, bruising lips, mucosa around the mouth, the teeth are gray purple, the face and exposed parts of the skin scattered small papules, hands Qidan, nails bruising and white spots, body temperature normal, blood pressure 96 / 60mmHg, heart rate Qi, heart rate 100 beats / min, no noise; lung (a), liver ribs 45cm, soft, no tenderness, laboratory tests
