There have been many accidents and crimes suspected drugs and poisons in our life. It becomes very important to elucidate a participation of the drugs and poisons. Blood and urine are usually used for detection of these drugs and poisons. However, it is not easy to identify the source of the poisoning from a huge number of drugs and poisons. Therefore, simple and accurate detection methods are requested for search of drugs and poisons in biological materials. In this study, the simple and fast detection methods of acetaminophen, paraquat, organophosphorus pesticides (fenitrothion), and arsenic in biological materials were developed to select the suspicious samples of poisoning from a lot of samples. The proposed methods were applied for forensic materials.
As a result, acetaminophen and paraquat in blood, and the arsenic in urine were able to be detected by the concentration of the poisoning level in combination with a deproteination or Reinsch test. The proposed methods were useful to evaluate the cause of death. These results have a potential for the detection of drugs in forensic and clinical samples. However, it is hoped to do certain qualitative and the quantitative analysis by the instrumental analysis because of only the presumption of the medicine poison in this method.
