Lead poisoning has been a significant public health problem for centuries since lead is a cumulative poison. Exposure to lead and lead compounds can be toxic to humans and wildlife. Potential effects in humans are abdominal cramps, learning disabilities, attention deficit disorder, constipation, anemia, tiredness, nerve damage, vomiting, convulsions, anorexia, and brain damage. Wildlife and waterfowl are also frequently poisoned through the ingestion of lead and lead shot. Toxic effects occur to the central nervous system and resulting long-term neurobehavioral and cognitive deficits occur even with mildly elevated blood lead levels. (reference)
