Children with excessive blood lead often do not have characteristic clinical manifestations, but mostly show hyperactivity, inattentiveness, and some are impulsive and irritable, so it is not only difficult for parents and teachers to find children with high lead levels, but also difficult for pediatricians to find children with excessive lead levels without blood lead measurement. Therefore, “blood lead screening” for children is the only way to detect lead poisoning or lead overload in children! Where can I get a blood lead screening test? At present, with the improvement of medical conditions and the popularization of domestic instruments, blood lead measurement can be done in many children’s hospitals and maternal and child health centers. In developed countries such as the United States, many places have passed legislation stipulating that children aged 0-6 must receive a blood lead screening once a year to find out whether there is lead poisoning or lead overload. The main type of lead pollution source for lead poisoning, or lead overload in children in China is industrial lead pollution, that is, parents are engaged in lead-related work, which may bring the lead in the working environment in the unit to the family environment through clothing, body and other ways, resulting in children being exposed to lead; there are also small lead working factories around the family, and such factories often lack the necessary protection facilities, which will lead to the discharge of lead from the factory to the The other category is living lead pollution, because of some bad traditional customs, such as burning tin foil, using tin pots to hold wine, drinks, water, etc., using red dan powder or yellow dan powder for infants and children to take care of their skin, or using partial prescriptions, experimental prescriptions and ancestral secret recipes for children, thus leading to children’s exposure to lead, which is then absorbed through the digestive tract, leading to lead poisoning or lead overload. Due to the traditional custom, which has a very obvious locality, a vast area centered on Jiangxi, including southwestern and southern Zhejiang; northern and western Fujian; some parts of Hunan; northern Jiangsu and other areas have the custom of traditionally using reddan powder to care for the skin of newborn babies, which is actually triple lead tetraoxide, leading to serious lead poisoning in small babies. Some areas in Hunan traditionally use yellow dan powder, which is lead oxide, to care for the skin of babies and children, and in recent years this custom has been introduced to some areas in Pudong, Shanghai, leading to serious lead poisoning in children. The use of tin pots is basically limited to some areas in Zhejiang and Jiangsu; the tin pots are usually used to hold yellow wine, and then the lead-contaminated yellow wine is used for frying and cooking, which leads to lead poisoning for the whole family; the habit of burning tin foil is widespread throughout the country, even including the vast Southeast Asian region, and the tin foil releases a lot of lead smoke when it burns, which pollutes the environment. Many prescriptions for the treatment of mouth ulcers, or bulking agents contain lead compounds, even mercury and arsenic compounds, which can also lead to poisoning, and lead compounds are also used to treat epilepsy, chronic diarrhea, and many skin diseases; this is more common in the north of China, and of course in the south. If any of these conditions exist, please take your child to have his or her blood lead measured! Early detection and early treatment.
