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 (pronounced "led") 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 ...
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 is a toxic metal. Exposure to significant levels, over time, can lead to a host of problems in children, especially those under 6 years old, ...
Lead exposure in the 20th century may have led to mental health issues in Americans, a new study suggests. Researchers from Duke University and Florida State University studied the impact of lead ...
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 ...
