Because of the teachers comment on his 8-year-old son, Attention is not focused, active, Yiwu and Hangzhou have been visiting many hospitals. As a result, Mr. Wu (pseudonym) has been found to be a five-member family with collective lead poisoning, and the main culprit is the tin pot filled with wine when offering sacrifices to ancestors.
In May, 2018, Mr. Wu went to Yiwu local hospital for examination because his 8-year-old son was often criticized by his teacher as inattentive and active, suggesting that the blood lead level was 270.8 ug/L, which was significantly higher than the national standard of 100 ug/L. First of all, they received Chinese medicine and other treatments locally, but the children were still in good or bad condition in class.
Then on Jan. 28, 2019, Mr. Wu took his children to the provincial childrens insurance for re-examination. The results showed that the blood lead level was 313.5ug/L. Compared with before treatment, it did not decrease but rose. Because the cause of lead poisoning in children is not clear, doctors advise the whole family to check blood lead. At the end of February, the results of the examination came out. Father, mother, daughter and son, including grandma, were five people in a family, all of whom were lead poisoned. After careful questioning by doctors, the culprit was the tin pot filled with wine when offering sacrifices to ancestors.
Mr. Wu said that in Yiwu, his ancestors need to be sacrificed every year for the Qingming Dynasty, the July and a half of the lunar calendar, the Winter Solstice, the New Years Eve, and the 15th day of the first lunar month. When sacrificing ancestors, Laodizi passed down to use tin pots to hold wine, but also need to be heated, because he could not let his ancestors drink cold wine. After the ancestor worship, in line with the principle of non-waste, the wine in the tin pot will be used as cooking wine and cooking. Unexpectedly, so unconsciously, the whole family poisoned.
Li Guohui, director of occupational disease department of Hangzhou Red Cross Hospital, told Qian Bao that tin itself is not poisonous, because most of the tin pots at present are not pure tin, often contain lead. After adding wine, lead in tin pots will slowly melt into wine, and heating accelerates the process. People eat lead-containing wine and lead poisoning subsequently occurs.
Director Li Guohui said that lead poisoning can lead to a series of abnormal manifestations of nervous system, digestive system, blood system and other systems.
In addition, besides tin pots, tinfoil paper (ghost coins) used in ancestral sacrifices, folding or burning such tinfoil paper can lead poisoning.
More noteworthy is that many patients with lead poisoning in clinic have no symptoms like other people in Mr. Wus family. Therefore, Director Li Guohui reminds us that if there are related life experiences or exposure to lead for various reasons, it is recommended to go to regular hospitals for blood lead examination in time. Never delay diagnosis and treatment because there are no symptoms.
