Symptoms from exposure to organic lead, which is probably more toxic than inorganic lead due to its lipid solubility, occur rapidly. [34] Poisoning by organic lead compounds has symptoms predominantly in the central nervous system, such as insomnia, delirium, cognitive deficits, tremor, hallucinations, and convulsions. [29]
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 (/ l ɛ d /) is a chemical element; it has symbol Pb (from Latin plumbum) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to ...
Surprising Lead-Tainted Foods. Lead, a naturally occurring toxic element found in the earth’s soil, can have serious health consequences with even minimal exposure.

Lead contamination issues in Flint, Michigan, and in schools across the nation have brought renewed attention to the threat posed by the toxic metal. Even at tiny doses, lead can be especially harmful to children whose brains and nervous systems are still developing.
Although lead has been banned from paint since 1978, lead poisoning still occurs. A medical expert explains the signs and symptoms of this public health problem.
Lead is widely understood to be toxic to multiple organs of the human body, particularly the human brain. Concerns about even low levels of exposure began in the 1970s; in the decades since, scientists have concluded that no safe threshold for lead exposure exists. [2] [3] The major source of lead exposure during the 20th century was leaded ...
