How to detect N-dimethylnitrosamine after eating it, and what does it taste like?

Suspicious points in Huang Yang’s case

Brief introduction to the case: Huang Yang was unwell and was hospitalized. The cause of the disease could not be found. Brother Huang Yang received a text message prompting a certain compound N-dimethylnitrosamine, so The clue pointed to Lin, Huang Yang's roommate who had the conditions to obtain the compound. Huang Yang died and Lin has been taken away by the police.

1. Who does the mysterious text message come from? It is said that on the 9th, senior brother Huang Yang received a text message reminding him to pay attention to a certain compound. There is no doubt that this text message was sent by an insider. There are three possibilities: First, the poisoner is Lin, who is afraid of Huang Yang's death. The second is that the poisoner was Lin, but it was learned by a third party, who used Lin's poisoning of Huang Yang to get rid of Lin and Huang. Third, the poisoner was someone else, who chose to use N-dimethylnitrosamine (a laboratory supply of Lin) to poison Huang Yang and blame Lin.

2. It is said that Jiang Cheng was a third person besides Huang Yang and Lin in the dormitory, but he did not live in the dormitory. Therefore, it is less likely that Jiang Cheng, the target of Lin's poisoning, accidentally killed Huang Yang.

3. "Zhu Jiangcheng" Baidu user asked about the pharmacological, toxicological and chemical properties of N-dimethylnitrosamine on Baidu Zhidao. These two incidents may be unrelated incidents, but it is said that the three people in Huang Yang's dormitory are Huang Yang, Lin, and Jiang Cheng. Combined with Lin's experiment with N-dimethylnitrosamine, the "Zhu Jiang Cheng" incident The possibility that people are related to the Huang Yang case is infinite. It is said that Lin has written a paper on N-dimethylnitrosamine and used it to conduct experiments on mice, so it is unlikely that he would ask about the toxicology of N-dimethylnitrosamine online. And it seems stupid to choose "Zhu Jiangcheng", a vest ID that can easily leave clues. There are three possibilities: First, "Zhu Jiangcheng" is Lin, who is stupid and not careful in his actions. The second is that "Zhu Jiangcheng" refers to Jiang Cheng himself. Third, there was a third person who "killed Jiang Cheng" and learned about the conflict between Lin and Jiang Cheng to frame the blame and poison.

Details of the case, I hope the police will investigate the case carefully. The unjust imprisonment case of uncle and nephew is a warning. We hope to be cautious and use scientific and technological means to obtain irrefutable evidence. Do not use torture to extract confessions. The truth of the case will be revealed as soon as possible. Huang Yang can rest in peace. If I can help you, I will be very happy
