The major source of lead exposure during the 20th century was leaded gasoline. Proponents of the lead–crime hypothesis argue that the removal of lead additives from motor fuel, and the consequent decline in children's lead exposure, explains the fall in crime rates in the United States beginning in the 1990s.

Over the last 17 years, a 50% decrease in the national prevalence rates of BLL ≥25 μg/dL has been documented using ABLES surveillance data. In 1994 the rate was 14.0 employed adults per 100,000; in 2010 the rate was reduced to 7.0. In 2010, 40 state ABLES programs that provided data reported 31,081 adults with BLLs ≥10 μg/dL.
Lead poisoning epidemics refer to specific instances of mass lead poisoning. These events often occur without the knowledge of the communities they affect. Common causes of lead poisoning epidemics include mining, lead recycling, and food/water contamination. [1] These events also cause disproportionate childhood fatalities as children are more ...
In the 18th century lead poisoning was fairly frequent on account of the widespread drinking of rum, which was made in stills with a lead component (the "worm"). It was a significant cause of mortality amongst slaves and sailors in the colonial West Indies. [280] [281] Lead poisoning from rum was also noted in Boston. [282]
Lead Exposure Elimination Project (LEEP) is an international non-governmental organization aimed at reducing lead exposure in low- and middle-income countries. [1] Based in London, England , it was founded in 2020 to promote research and advocacy on the prevalence and consequences of lead poisoning in the developing world. [ 1 ]
Incidence should not be confused with prevalence, which is the proportion of cases in the population at a given time rather than rate of occurrence of new cases. Thus, incidence conveys information about the risk of contracting the disease, whereas prevalence indicates how widespread the disease is.
As Gen-Z drinks less, other age groups follow suit. The most recent National Survey on Drug Use and Health found less than two-thirds of Americans drank alcohol at least once in 2022. According to ...
Period prevalence (proportion) = Number of cases that existed in a given period ÷ Number of people in the population during this period [citation needed] The relationship between incidence (rate), point prevalence (ratio) and period prevalence (ratio) is easily explained via an analogy with photography.
