Final NTP monograph on the health effects of low-level lead exposure

Low levels of lead in the blood (below 10 µg/dl) have been associated with a range of adverse health effects in humans. Overall, the NTP concludes that there is “sufficient” evidence of an association in children, including delayed puberty, reduced postnatal growth and adverse neurological effects (including decreased IQ and hearing), and in adults, including reduced foetal growth in pregnant women and adverse effects on the cardiovascular system. Even at blood lead levels of less than 5 µg/dl there is “sufficient” evidence of decreased cognitive performance and increased diagnosis of attention deficit hyperactivity disorder (ADHD) and problem behaviours in children, and effects on the kidneys in adults.
