The neurological and behavioural effects of lead are believed to be irreversible. There is no known safe blood lead concentration. But it is known that, as lead exposure increases, the range and severity of symptoms and effects also increases.
Lead poisoning is most often a chronic disorder and may not cause acute symptoms. With or without acute symptoms, poisoning eventually has irreversible effects (eg, cognitive deficits, peripheral neuropathy, progressive renal dysfunction). Symptoms of lead poisoning are roughly proportional to lead levels, but there are no safe levels of lead. Risk of cognitive deficits increases when the whole blood lead level (PbB) is â¥ 10 Î¼g/dL (â¥ 0.48 mmol/L) for an extended period, although the cutoff may be even lower.
