The following is an inventory of thallium poisoning incidents that have occurred in recent years, totaling about 1,000 words:
1. The thallium poisoning incident of Zhu Ling of Tsinghua University
On November 24, 1994, Zhu Ling, a female student at Tsinghua University, began to experience symptoms of poisoning, including abdominal pain, stomach discomfort, and hair loss. After a month of hospitalization, the condition was relieved, but the hair was still falling out. Zhu Ling's symptoms were very similar to a case of thallium poisoning at Tsinghua University in the 60s, but the investigation found that Zhu Ling had no opportunity to come into contact with thallium salt, and the Union Hospital at that time did not have the conditions to detect thallium poisoning, so this conjecture was not confirmed at the time. After asking for help on the Internet, Zhu Ling's illness received the attention of foreign experts, and he was finally diagnosed with thallium poisoning. The incident has aroused widespread social concern and discussion, prompting relevant departments to strengthen the supervision and management of thallium.
2. The thallium poisoning and death of a female student at Nanjing Medical University
In July 2009, a female student at Nanjing Medical University used thallium salt in the laboratory for experiments, and then developed abdominal pain, vomiting and other symptoms. Although she was rescued, her life could not be saved. The investigation found that the girl had been exposed to large amounts of thallium salts in the laboratory. The incident has attracted widespread attention and mourning, and it has also reminded relevant institutions to strengthen laboratory safety management and experimental operation practices.
3. Thallium poisoning incident of female students at Sichuan University
In March 2013, a female student at Sichuan University was found to have thallium poisoning. She began to lose her hair frequently and experienced symptoms such as stomach pain, nausea, etc. After several tests, doctors finally diagnosed thallium poisoning. After treatment, the girl's condition was controlled, but her hair fell out severely and could not regrow. This incident has aroused widespread social attention and discussion, and at the same time, it has also prompted relevant institutions to strengthen the management and safety precautions of university laboratories.
4. Other thallium poisoning incidents
In addition to the above three typical incidents, there have been a number of thallium poisoning incidents in recent years. For example, in July 2011, a male student from Wuhan University of Technology was diagnosed with thallium poisoning when he went to the hospital unwell. The boy's condition improved after receiving treatment, but he developed symptoms such as vision loss and hair loss. After investigation, the cause of the boy's thallium poisoning was the insecticide containing thallium he used. In addition, there are some cases of thallium poisoning caused by accidental ingestion and misuse. These incidents have not only brought great suffering and loss to the victims, but also sounded the alarm bell for the society, reminding people to always be vigilant and strengthen their awareness of safety precautions.
5. Summary and reflection
The above inventory of thallium poisoning incidents shows that despite the continuous development of modern technology and medical methods, there are still many challenges and loopholes in the prevention and management of highly toxic elements such as thallium. The occurrence of these incidents not only brought great suffering and loss to the victims and their families, but also exposed the deficiencies and loopholes of relevant institutions in terms of safety management and experimental operation specifications. Therefore, we need to strengthen prevention and management from the following aspects: first, strengthen publicity and education to raise the public's understanding of the dangers of thallium and other highly toxic elements; second, strengthen the construction and implementation of safety management systems; third, improve the emergency response mechanism and rescue system; and fourth, strengthen international cooperation and exchanges to jointly address challenges. Only in this way can we minimize the occurrence of similar incidents and protect the people's life safety and health rights.
