　　The dangers of excessive cadmium

　　Cadmium is a toxic heavy metal. Long-term intake will affect human hematopoiesis, nerve , kidneys and other organ functions, giving the human body healthy It brings great harm, especially to children. Excessive cadmium in children mainly comes from factory pollution, food pollution and passive smoking.

　　After cadmium is absorbed by the human body, it can easily cause a series of symptoms such as osteoporosis and deformation. “Itai-itai disease" is the most typical example of chronic cadmium poisoning. The disease is characterized by pain, starting from low back pain, followed by shoulder, knee, and hip joint pain, and gradually extending to the whole body.

　　The amount of cadmium in food is affected by the natural environment. According to reports, in fact, as early as 2002, the Rice and Products Quality Supervision, Inspection and Testing Center of the Ministry of Agriculture conducted safety inspections on rice on the national market. The most serious heavy metal in rice that exceeded the standard was lead, with an exceeding rate of 28.4%, followed by cadmium, with an exceeding rate of 10.3%. Research by Chen Tongbin, a researcher at the Institute of Geographic Sciences and Natural Resources of the Chinese Academy of Sciences, also found that my country's cultivated land has the largest proportion of cadmium pollution and arsenic pollution. The land contaminated by cadmium alone may reach about 80 million acres, and most of these contaminated areas are still growing rice. Based on this, it is an indisputable fact that cadmium in rice exceeds the standard.

　　One of the foods with excessive cadmium content: molluscs, crustaceans, grains, etc. have relatively high contents. Cigarettes contain high levels of cadmium, so cadmium levels in smokers' bodies increase significantly. The main absorption pathways of cadmium are the respiratory tract and digestive tract. skin Very little absorption. Japanese epilepsy is a type of chronic cadmium poisoning caused by long-term ingestion of water contaminated with cadmium sulfate. Manifested as pulmonary edema, kidney damage, anemia , and the toxic effects of timely testicles.
