Lead Poisoning Effects

Improved Essays
Lead is a toxic metal that can enter the body by inhalation of lead dust or ingestion when touching the mouth with lead-contaminated hands. If leaked onto the ground, acid and lead particles contaminate the soil and become airborne when dry. Children and fetuses of pregnant women are most vulnerable to lead exposure because their bodies are developing. Excessive levels of lead can affect a child’s growth, cause brain damage, harm kidneys, impair hearing and induce behavioral problems. In adults, lead can cause memory loss and lower the ability to concentrate, as well as harm the reproductive system. Lead is also known to cause high blood pressure, nerve disorders, and muscle and joint pain. Researchers speculate that Ludwig van Beethoven became ill and died because of lead poisoning. …show more content…

Always wear protective equipment when handling sulfuric acid.Cadmium used in nickel-cadmium batteries is considered more harmful than lead if ingested. Workers at NiCd manufacturing plants in Japan have been experiencing health problems from prolonged exposure to the metal, and governments have banned disposal of nickel-cadmium batteries in landfills. The soft, whitish metal that occurs naturally in the soil can damage kidneys. Cadmium can be absorbed through the skin by touching a spilled battery. Since most NiCd batteries are sealed, there are no health risks in handling intact cells; caution is required when working with an open

    The toxicology of the chemical, lead, affects the brain because in a developing brain, such as a child’s, the cells are still being produced, therefore can be easily manipulated by the low or high levels of exposure to lead. Lead acts as a poison to the brain as it harms the mitochondria, which is critical for energy fabrication within the neuron, and an alteration in this function may damage the cell, because it does not have the proper building blocks to make it work properly, and to do its function. Lead also affects the brain’s function by interfering with neuron-transmitter release and synapse formation. Lead affects different parts of the brain such as the cerebral cortex, cerebellum, and hippocampus. The cerebral cortex assists in action…
