It had been used as a general anaesthetic since the 19th century, but it disappeared, because of its hepatotoxicity and arrhythmia-inducing effects. It is now being used for industrial purposes, such as a solvent, extracting reagent, refrigerant and chemical material. Chloroform poisoning can be seen in accidental, suicidal [1] and homicidal cases.

The ratio of the nonionic form to the total ionized one is influenced by concentration of hydrogen ion in the solution. Under acidic conditions, H2S does not ionized and evaporated from water; under alkaline conditions it is easily ionized and retained in the solution.

  • Introduction: Methanol (methyl alcohol) poisoning accidents take place most frequently by drinking it in mistake for ethanol. Methanol poisoning is not due to the effect of methanol itself, but due to toxicity of its metabolites. Methanol is rapidly absorbed into human body through the airway mucous membranes, digestive tract mucous membranes or the skin; it is metabolized into formaldehyde (formalin, HCHO) and then formic acid (HCOOH) by the actions of alcohol dehydrogenase and aldehyde dehydrogenase, respectively.

  • Introduction: Alkyl nitrites are highly volatile organic solvents of aliphatic alcohol esters of nitrites [1]. Amyl nitritea, butyl nitrite and isobutyl nitrite are the representative alkyl nitrites; their boiling points are 98, 78 and 67 °C, respectively. Amyl nitrite is being widely used as a detoxicant for cyanide poisoning, because alkyl nitrites oxidize hemoglobin in erythrocytes to yield methemogloblin, which is bound with cyanide to inactivate it [1].
