Lead has the most serious impact on neurobehavior.

The common clinical manifestations of lead's impact on children's neurobehavior are children's hyperactive behavior: distracted attention, impulsiveness, and excessive activity. This is because lead poisoning can cause brain excitement and inhibition dysfunction; inactivate and denature brain activity proteins, causing the death of certain brain cells and stopping related functional activities; destroying the blood-brain barrier, allowing too much water and poisons in the blood to enter the brain tissue, causing brain edema; preventing neural development from being synchronized, destroying the brain network structure, and causing integration and coordination dysfunction.

Lead can hinder the development and growth of children

Lead can cause the physical growth of children to lag behind; cause low nutritional status of iron, zinc, and calcium; directly affect the response of thyroid-stimulating hormone to thyroid-stimulating hormone The reaction of releasing hormones disrupts thyroid secretion, thereby affecting children's normal physiological and metabolic activities.

Lead poisoning can cause sensory dysfunction

such as amblyopia, retinal edema, retrobulbar optic neuritis, blind spots, abductor muscle paralysis, optic atrophy, eye movement disorders, and pupillary accommodation abnormalities. , amblyopia or visual field changes; or smell, taste disorders, etc.

Lead poisoning causes anemia in children

The main effects of lead on the blood system are to inhibit the synthesis of hemoglobin and to shorten the life of red blood cells in the circulation. These effects will eventually lead to anemia.

Lead poisoning damages multiple other systems

For example, digestive system disorders, such as stomach problems; exercise imbalance or slow response; decreased kidney function and cardiovascular function; and affects reproductive health.
