Lead is a potent neurotoxin that can affect nearly every system in the body. In children, lead exposure can result in developmental delays, learning difficulties, and reduced IQ. In adults, it can cause hypertension, renal impairment, and reproductive toxicity. Mercury, particularly methylmercury, is also a neurotoxin and is associated with neurological and behavioral disorders. Prenatal and early childhood exposure to mercury can lead to cognitive deficits, motor dysfunction, and sensory impairments.
