Lead poisoning, also known as plumbism and saturnism, is a type of metal poisoning caused by lead in the body. [2] Symptoms may include abdominal pain, constipation, headaches, irritability, memory problems, infertility,numbness and tingling in the hands and feet. [1]
Blood lead level (BLL), is a measure of the amount of lead in the blood. [1] [2] Lead is a toxic heavy metal and can cause neurological damage, especially among children, at any detectable level. High lead levels cause decreased vitamin D and haemoglobin synthesis as well as anemia, acute central nervous system disorders, and possibly death. [3]
In the case of lead, any measurable amount may have negative health effects. [2] There is a popular misconception that only heavy metals can be toxic, but lighter metals such as beryllium and lithium can be toxic too. [3] Not all heavy metals are particularly toxic, and some are essential, such as iron.
"Lead is a known neurotoxin, and cadmium has been shown to cause harmful effects to bones and kidneys," says Felicia Wu, PhD, a professor of food safety, toxicology, and risk assessment at ...
Lead exposure in early childhood is known to cause severe cognitive impairment into adolescence, but new research suggests that these effects may be reversible. The study, published in Scientific ...
Lead was used extensively in Roman aqueducts from about 500 BC to 300 AD. [54] Julius Caesar's engineer, Vitruvius, reported, "water is much more wholesome from earthenware pipes than from lead pipes. For it seems to be made injurious by lead, because white lead is produced by it, and this is said to be harmful to the human body."
Consumer Reports tracked the amount of lead in Lunchables by percentage of California’s maximum allowable dose level, which is 0.5 micrograms per day for lead.
Its prevalence in the human body—at an adult average of 120 mg [t] —is nevertheless exceeded only by zinc (2500 mg) and iron (4000 mg) among the heavy metals. [259] Lead salts are very efficiently absorbed by the body. [260] A small amount of lead (1%) is stored in bones; the rest is excreted in urine and feces within a few weeks of exposure.
