| 毒性 | CK may polymerize violently if contaminated with hydrogen chloride or ammonium chloride. Upon heating, it decomposes, producing toxic and corrosive fumes of hydrogen cyanide, hydrochloric acid, and nitrogen oxides. Hazardous polymerization can occur. Cyanogen chloride will react slowly with water to form hydrogen chloride gas. It acts on the body in two ways. Systemic effects of CK are much like those of hydrogen cyanide. Additionally, it causes irritation of the eyes, upper respiratory tract, and lungs. Eye irritation results in tearing. CK, like AC, stimulates the respiratory system and rapidly paralyzes it. Exposure is followed by immediate, intense irritation of the nose, throat, and eyes, with coughing, tightness in the chest, and lacrimation. This is followed by dizziness and increasing difficulty breathing. Unconsciousness comes next, with failing respiration and death within a few minutes. Convulsions, retching, and involuntary urination and defecation may occur. If these effects are not fatal, the signs and symptoms of pulmonary edema may develop. There may be repeated coughing, with profuse foamy sputum, rales in the chest, severe dyspnea, and distinct cyanosis. Recovery from the systemic effects is usually as prompt as in AC poisoning. However, a higher incidence of residual damage to the central nervous system should be expected. Based upon the concentration of the cyanogen chloride to which the victim has been exposed, the pulmonary effects may evolve instantly or may be delayed until the systemic effects have subsided. Consequently, early prognosis must be cautious. |
