First, Yongjia couple poisoned Yongjia with tin pots. Mr. Zhu was constipated six months ago and didn't care at that time. But when I was working at home, I found that my stomach hurt very much, which lasted for more than ten days. I couldn't take it anymore, so I went to the hospital. After a series of tests, the doctor found that it was chronic lead poisoning after blood lead examination. Through consultation, I learned that Mr. Zhu used a tin pot for shochu at home, which was often used for cooking. The doctor saw the photo of the tin can and determined that the cause of poisoning came from the tin can. Mr. Zhu's wife went to the hospital for examination and found that the lead content in Ms. Zhu's blood also exceeded the standard. After diagnosis and treatment, he has been discharged from hospital healthily.
Second, the reason why tin pots make people poisoned In fact, pure tin pots will not make people poisoned. In ancient China, people liked to use tin vessels as flagons, and then they used teapots. Until now, it is also a common object of people. However, why does the phenomenon of poisoning caused by the use of tin pots appear frequently? This is because tin cans are not made of pure tin, but contain lead. When wine is packed in tin cans, lead and wine produce lead acetate. After drinking, this ingredient will be absorbed by human body in blood and bone in the form of lead ammonium phosphate. If eaten for a long time, lead poisoning will occur.
Pure tin containers will not cause poisoning. When lead is added to tin pots, when people use tin pots to fill wine, the toxicity of lead and wine will cause chronic lead poisoning if they drink it for a long time. At present, many media reports that long-term use of tin pots can poison people. This statement is wrong. Tin itself is non-toxic and is a trace element needed by human body, especially for anti-tumor, but it must be made of pure tin.
