• 致癌性证据

评估：有足够的人类证据表明硫酸镍具有致癌性，以及镍精炼工业中遇到的镍硫化物和氧化物的组合也具有致癌性。关于金属镍和镍合金的人类致癌性证据不足。有足够的实验动物证据表明金属镍、一氧化镍、氢氧化镍和结晶镍硫化物具有致癌性。对于镍合金、镍ocene、镍羰基、镍盐、镍砷化物、镍锑化物、镍硒化物和镍碲化物的致癌性，实验动物中的证据有限。对于三氧化二镍、非晶态镍硫化物和镍钛酸盐的致癌性，实验动物中的证据不足。工作组根据流行病学研究、实验动物致癌性研究以及几种其他相关数据的结果，结合镍化合物在其靶细胞的关键位点可以生成镍离子的基本概念，对镍化合物作为一组进行了总体评估。总体评估：镍化合物对人类具有致癌性（第1组）。金属镍可能对人类具有致癌性（第2B组）。/镍化合物/

Evaluation: There is sufficient evidence in humans for the carcinogenicity of nickel sulfate, and of the combinations of nickel sulfides and oxides encountered in the nickel refining industry. There is inadequate evidence in humans for the carcinogenicity of metallic nickel and nickel alloys. There is sufficient evidence in experimental animals for the carcinogenicity of metallic nickel, nickel monoxides, nickel hydroxides and crystalline nickel sulfides. There is limited evidence in experimental animals for the carcinogenicity of nickel alloys, nickelocene, nickel carbonyl, nickel salts, nickel arsenides, nickel antimonide, nickel selenides and nickel telluride. There is inadequate evidence in experimental animals for the carcinogenicity of nickel trioxide, amorphous nickel sulfide and nickel titanate. The Working Group made the overall evaluation on nickel compounds as a group on the basis of the combined results of epidemiological studies, carcinogenicity studies in experimental animals, and several types of other relevant data, supported by the underlying concept that nickel compounds can generate nickel ions at critical sites in their target cells. Overall evaluation: Nickel compounds are carcinogenic to humans (Group 1). Metallic nickel is possibly carcinogenic to humans (Group 2B). /Nickel compounds/

• 解毒与急救

高级治疗：对于无意识的病人，考虑进行口咽或鼻咽气管插管以控制气道。使用气囊面罩装置的正压通气技术可能有益。监测心率和必要时治疗心律失常。考虑使用药物治疗肺水肿。开始静脉输液，使用5%葡萄糖盐水/生理盐水维持通道，最小流量。如果出现低血容量的迹象，使用乳酸钠林格氏液。对于伴有低血容量迹象的低血压，谨慎给予液体。如果液体量正常但仍有低血压，考虑使用血管加压药。密切观察液体过载的迹象。使用丙美卡因氢氯化物协助眼部冲洗。/镍及其相关化合物/

Advanced treatment: Consider orotracheal or nasotracheal intubation for airway control in the patient who is unconscious. Positive pressure ventilation techniques with a bag valve mask device may be beneficial. Monitor cardiac rhythm and treat arrhythmias if necessary ... . Consider drug therapy for pulmonary edema ... . Start an IV with D5W /SRP: "To keep open", minimal flow rate/. Use lactated Ringer's if signs of hypovolemia are present.
