It contains lead, so the symptoms of poisoning are the symptoms of lead poisoning, as follows:
Adult lead poisoning often appears: fatigue, depression, heart failure, abdominal pain, kidney deficiency, hypertension, joint pain, reproductive disorders, anemia and other symptoms. After lead poisoning in pregnant women, there will be serious consequences such as abortion, low birth weight, stillbirth and infant dysplasia. Children often have symptoms such as loss of appetite, stomachache, insomnia, learning disabilities, constipation, nausea, diarrhea, fatigue, low IQ and anemia.
The harm of lead poisoning is mainly manifested in the lifelong damage to nervous system, blood system, cardiovascular system and skeletal system:
Lead has a direct toxic effect on specific nerve structures of multiple central and peripheral nervous systems. In the central nervous system, the cerebral cortex and cerebellum are the main target tissues of lead toxicity; In the peripheral nervous system, motor axons are the main target tissues of lead poisoning. Among them, the toxicity of lead to the nervous system is mainly manifested in the following four aspects: (1) It changes the psychology of patients with lead poisoning. Adults show depression, irritability and personality changes, while children show hyperactivity. (2) Lead poisoning can lead to mental decline, especially for children with learning disabilities. It is reported that the IQ of children with high lead is 4-6 points lower than that of children with low lead. (3) Lead poisoning can lead to sensory dysfunction. For example, many patients with lead poisoning will have visual dysfunction: retinal edema, retrobulbar optic neuritis, blind spots, abductor paralysis, optic atrophy, eye movement disorder, abnormal pupil accommodation, amblyopia or visual field changes; Or smell, taste disorders, etc. (4) The main effect of lead on peripheral nervous system is to reduce motor function and nerve conduction velocity, and muscle injury is one of the typical proofs of severe lead poisoning.
Lead has two main effects on the blood system, one is to inhibit the synthesis of hemoglobin, the other is to shorten the life of circulating red blood cells, which will eventually lead to anemia.
The damage of lead to cardiovascular system is mainly manifested in: (1) The mortality of cardiovascular diseases is closely related to the excessive lead in arteries, and the blood lead and 24-hour urine lead levels of patients with cardiovascular diseases are significantly higher than those of patients without cardiovascular diseases. (2) Lead exposure can cause hypertension. (3) Lead exposure can cause heart diseases and changes in heart function.
Bone is an important target organ system of lead toxicity. On the one hand, lead indirectly affects bone function and bone mineral metabolism by damaging endocrine organs; On the other hand, it poisons cells, interferes with basic cell processes and enzyme functions, changes the coupling relationship between osteoblasts and osteoclasts, affects the calcium system, and directly interferes with the function of bone cells.
