C.2 Symptoms of Lead Poisoning
Children with elevated blood lead levels (EBLLs) in the range of 10-45µg/dL may be asymptomatic, although impairment of neurodevelopment may become evident as they get older. Very high lead levels may cause colic, constipation, anorexia, or vomiting. Children with venous blood lead levels (BLLs) over 44µg/dL are eligible for medical intervention. However, it is important not to equate the absence of symptoms with the absence of toxicity.
