镉是面粉中有害物质之一,它对人体的危害较大,人体中的镉主要通过食物摄入,微量的镉也会对肾脏产生危害。镉对人体的危害在临床上主要表现为肺水肿、蛋白尿、氨基酸尿、骨质疏松等。由于环境受到镉的污染,小麦在生长过程中,通过生物作用和吸附作用吸收蓄积于体内。面粉被人体食用后,其中的镉进入消化系统,未被排出的部分在人体的某些部位蓄积,进而危害人体健康。因此要严格监控面粉中镉的含量。目前面粉中镉测定的国家标准方法有石墨炉原
Cadmium is one of the harmful substances in flour. It is harmful to the human body. Cadmium in the human body is mainly consumed through food. Trace amounts of cadmium also cause harm to the kidneys. Cadmium harm to the human body mainly in clinical manifestations of pulmonary edema, proteinuria, amino acid urine, osteoporosis and so on. Due to environmental pollution by cadmium, wheat grows through the biological action and adsorption absorbed in the body. After flour is consumed by the human body, the cadmium enters the digestive system, and the non-excreted part accumulates in certain parts of the human body, thereby endangering human health. Therefore, to strictly monitor the content of cadmium in flour. At present, the national standard method for the determination of cadmium in flour is graphite furnace
