Lead Toxicity The major mechanism of lead toxicity is due to increased generation of reactive oxygen species (ROS) and interference with generation of antioxidants. Lead causes the generation of ROS like hydroperoxide, hydrogen peroxide, and singlet oxygen. ROS are stabilized by glutathione in the body.

Occupational Safety and Health Administration Industry Group Profile - Lead Exposure. Inorganic lead is a malleable, blue-gray, heavy metal that occurs naturally in the Earth’s crust. Lead was one of the first metals used by humans and consequently, the cause of the first recorded occupational disease (lead colic in a 4th century BC metal worker). In 2012, U.S. production of lead was estimated at 1.6 million metric tons; primarily from secondary refining of scrap metal.

Lead Poisoning - Topic Overview Lead poisoning occurs when you absorb too much lead by breathing or swallowing a substance with lead in it, such as paint, dust, water, or food. Lead can damage almost every organ system. In children, too much lead in the body can cause lasting problems with growth and development. These can affect behavior, hearing, and learning and can slow the child's growth.

- Adults can also be affected by lead. When lead dust is inhaled or ingested, adults can develop high blood pressure, hypertension, kidney problems, digestive issues, memory and concentration problems, and joint and muscle aches, among other conditions. Lead poisoning is, however, completely preventable.

Lead paint Further information: Lead poisoning. Lead paint is hazardous. It can cause nervous system damage, stunted growth, kidney damage, and delayed development. It is dangerous to children because it tastes sweet, therefore encouraging children to put lead chips and toys with lead dust in their mouths. Lead paint is dangerous to adults and can cause reproductive problems in men or women. Decreases in sperm production in men have been noted.

Overview Lead poisoning occurs when lead builds up in the body, often over months or years. Even small amounts of lead can cause serious health problems. Children younger than 6 years are especially vulnerable to lead poisoning, which can severely affect mental and physical development. At very high levels, lead poisoning can be fatal. Lead-based paint and lead-contaminated dust in older buildings are the most common sources of lead poisoning in children. Other sources include contaminated air, water and soil. Adults who work with batteries, do home renovations or work in auto repair shops also might be exposed to lead.

Learn about Lead Lead is a naturally occurring element found in small amounts in the earth’s crust. While it has some beneficial uses, it can be toxic to humans and animals causing of health effects. Lead can be found in all parts of our environment – the air, the soil, the water, and even inside our homes. Much of our exposure comes from human activities including the use of fossil fuels including past use of leaded gasoline, some types of industrial facilities, and past use of lead-based paint in homes.
