| Description | Lead is a chemical element in the carbon group with symbol Pb and atomic number 82. Like the element mercury, another heavy metal, lead is a neurotoxin that accumulates both in soft tissues and the bones. Lead can be ingested through fruits and vegetables contaminated by high levels of lead in the soils they were grown in. Soil is contaminated through particulate accumulation from lead in pipes, lead paint and residual emissions from leaded gasoline that was used before the Environment Protection Agency issue the regulation around 1980. [Wikipedia]. Lead is found in many foods, some of which are blackcurrant, asparagus, endive, and flaxseed. |
