Determination of lead, cadmium, mercury and inorganic arsenic in rice by atomic fluorescence spectrometry

When harmful metals enter the human body, they mostly exist in the form of metal elements or metal ions, and some can be converted into more toxic compounds. A large dose can cause acute poisoning, but most of them are chronic hazards caused by accumulation in the body after long-term ingestion of low doses. Lead mainly invades the nervous system, hematopoietic organs and kidneys in the human body. Common symptoms of poisoning include loss of appetite, gastroenteritis, metallic taste in the mouth, insomnia, dizziness, joint muscle pain, abdominal pain and constipation or diarrhea, anemia, etc. Acute abdominal pain or paralysis. After entering the body, cadmium is mainly accumulated in the liver, followed by the kidney. Cadmium poisoning mainly damages the kidneys, bones, and digestive system. Clinically, proteinuria, amino acid urine, glycosuria, and hypercalciuria may occur. The excretion of calcium causes muscle pain, osteoporosis, and pathological fractures. The mercury absorbed by the human body is distributed in tissues and organs throughout the body, with the highest content in the liver, kidney, and brain, causing damage to the brain and nervous system. The properties of arsenic are similar to metals, which can cause metabolic disorders, lead to increased capillary permeability, and cause extensive lesions in multiple organs. It can also cause acute poisoning and even death; chronic poisoning includes neurasthenia, neuralgia in the limbs, and abnormal skin pigments. Arsenic and its compounds have carcinogenic effects.
