What harm does lead do to human body? Five hazards of lead to human body.

1 Damage to the human nervous system Lead can damage the human nervous system through the blood-brain barrier, which may lead to slow response, inability to concentrate, and even lead to mental retardation, blindness, cerebral palsy and other uncomfortable symptoms.

2 Damage to the liver Lead can directly damage human liver cells after entering the human body, thus causing discomfort symptoms such as hepatomegaly and abnormal liver function, leading to disorder of human liver function, which is not conducive to human health.

3 Damage to human blood system After lead enters human blood, it will lead to improper synthesis of human hemoglobin and anemia symptoms. Secondly, lead can also dissolve sodium ions in human cells, leading to hemolysis, which is not conducive to human health.

4 Damage to the urinary system Excessive lead accumulation in the human body will also affect the mitochondrial function of human renal tubules, thus causing renal tubular dysfunction. In severe cases, it will also lead to renal tubular flushing dysfunction, that is, sodium excretion and uric acid excretion decline, which poses a certain threat to human health.
