Lead is a heavy metal that has been used for thousands of years due to its malleability, low melting point, and resistance to corrosion [26], [6], [29]. However, it is now recognized as a toxic substance with no known safe level of exposure [16].
Oldest smelted lead object discovered in a cave in Israel [29].
General Motors engineer Thomas Midgley Jr. discovers that tetraethyl lead (TEL) reduces engine knock, improving performance [33].
TEL production begins, immediately causing worker deaths [33].
New York, Philadelphia, and New Jersey temporarily ban leaded gasoline following worker deaths [33].
First clinical studies showed that leaded gasoline had toxic impacts on humans [30].
Japan becomes the first country to ban leaded gasoline completely [30].
Algeria became the last country to ban leaded gasoline [30].
Lead exposure can cause developmental neurotoxicity in young children, cardiovascular effects, and nephrotoxicity in adults [2].
Even low blood lead levels can have long-term effects on a child's IQ, academic achievement, and ability to pay attention [21], [7], [8].
Childhood lead exposure is associated with adult personality traits and lifelong mental health issues [15].
Lead can accumulate in the body over time, interfering with vital processes [12], [47].
Scientific Opinion on Lead in Food (EFSA Journal, 2010)
Identified developmental neurotoxicity in young children and cardiovascular effects and nephrotoxicity in adults as critical effects for risk assessment [2].
The effect of lead exposure on IQ test scores in children under 12 years: a systematic review and meta-analysis of case-control studies (Syst Rev, 2022)
Demonstrates that the concentration and duration of lead exposure have a large effect on mental function in children [8], [7].
Lead Exposure and Cardiovascular Disease—A Systematic Review (Environ Health Perspect, 2006)
Evaluates the evidence on the association between lead exposure and cardiovascular disease [5].
Unsafe. There is no known safe level of lead exposure [16].
While it is not possible to completely prevent lead from entering the food supply, the FDA monitors and regulates levels of lead in foods, and manufacturers have a responsibility to minimize or prevent chemical hazards [16].
Test your home for lead paint and dust, especially if it was built before 1978 [21].
Use cold water for drinking and cooking, as hot water is more likely to contain lead from plumbing [20].
Flush your pipes by running the water for a few minutes before using it, especially if the water has been sitting for several hours [23].
Eat a balanced diet rich in iron, calcium, and vitamin C, which can help reduce lead absorption [41].
Be aware of potential sources of lead exposure in your community, such as industrial facilities or contaminated soil [6].
Check product recalls and safety alerts for lead contamination in food, spices, and other consumer goods [16], [36], [37].
