😟😟😟 Exposure to lead can result in a variety of effects upon neuropsychological functioning including deficits in general intellectual functioning, ability to sustain attention on tasks, organization of thinking and behavior, speech articulation, language comprehension and production, learning and memory efficiency, fine motor skills, high activity level, reduced problem solving flexibility and poor behavioral self-control.

Given the risk of dysfunction, the neuropsychological evaluation assesses the child's cognitive and behavioral functioning with respect to the neurotoxic effects of lead. The kinds of neuropsychological problems resulting from lead poisoning can vary with the nature of the exposure history (intensity, chronicity, age at exposure, etc.) combined with the other contributing risk factors (nutrition, environmental stimulation).

The outcome of these neuropsychological deficits for the child is often quite debilitating and include poor academic learning and performance as well as problems with the development of appropriate social relationships. It is important to understand the child's neuropsychological strengths and deficits in order to reduce the risks of lead poisoning by planning for appropriate developmental, family, educational and behavioral treatment interventions.

😟😟😟 Since the 1970s, fi****ms and shooting ranges have been recognized as high risk for elevated lead exposure [1,2]. Mean blood lead levels (BLL) observed in studies of users of shooting ranges have ranged from 10 µg/dL to over 40 µg/dL [3,4,5]. Several studies have shown that the BLL may take a substantial amount of time to decrease after the cessation of shooting especially in those with very high levels or those that have practiced shooting for extended periods [6,7,8,9]. Higher BLLs were associated with a larger caliber of firearm [10], higher frequency of shooting [3,6], and the use of indoor rather than outdoor shooting ranges [3]. Whether the bullet was jacketed or not did not significantly impact BLL [11].
Ingestion and inhalation are the primary routes of lead exposure in shooting ranges [12,13]. Inhalation occurs when the gun is fired and fine airborne particles from the primer are released [14]. Both fine and coarse particles may contaminate hands, skin, hair, clothing, shoes, and other surfaces and could potentially be ingested especially in case of poor hand hygiene [3,15]. It is also possible that lead particles may be transported to other environments including vehicles and homes.
Lead exposure contributed to approximately 16.8 million disability-adjusted life years (DALY’s) to the global burden of disease in 2013 [16,17]. Even though lead primarily targets the nervous system [13,18], it is a multifaceted toxic substance with systemic clinical manifestations involving the cardiovascular [19,20], renal [21,22], hepatic [23], reproductive system [24,25], and immune system [26]. Lead exposure has been associated with psycho-neurological disorders such as behavioral changes, impaired cognitive function in adults, and reduced intelligence in children [13,18,27,28]. Aggressive behavior in adulthood following childhood lead exposure has been documented in several studies [29,30]. However, there is a relative dearth of information on lead exposure in adult shooters especially in developing countries and its association with aggressive behavior. In this study, we examined the association between BLL in users of shooting ranges and aggressive behavior.

😟😟😟 CLEVELAND, Ohio – A longstanding group of lead safety activists gathered in City Hall’s rotunda Monday morning to remind Mayor Justin Bibb that childhood lead poisoning must be “public enemy #1.”

Cleveland Lead Advocates for Safe Housing, better known as CLASH, held a press conference to call out what the group sees as a lack of meaningful progress in reducing the number of kids poisoned by lead each year.

😟😢😢 The brain is the most sensitive organ to lead exposure (Cleveland et al., 2008). In a child's developing brain, synapse formation is greatly affected in the cerebral cortex by lead. Lead also interferes with the development of neurochemicals, including neurotransmitters, and organisation of ion channels (Casarett et al., 2007). Lead poisoning also causes loss of neuron myelin sheath, reduction in the number of neurons, it interferes with neurotransmission and decreases neuronal growth (Pearson & Schonfeld, 2003). The brain of adults exposed to increased lead levels during their childhood also shows a decreased volume, especially in the prefrontal cortex on MRI (Cleveland et al., 2008)

😩😩😩 The study showed that from 1990 to 2015 blood lead levels in children declined substantially — but levels in non-Hispanic Black children living in racially segregated neighborhoods remain higher than in children living outside those communities.

“In the United States, one of the clearest examples of the link between racial residential segregation and environmental exposures is childhood lead exposure – which has been shown to be disproportionately burdensome to members of the Black community,” said Marie Lynn Miranda, director of CEHI and adjunct professor in the Department of Applied and Computational Mathematics and Statistics at Notre Dame. “We found that in 1990 there was a strong relationship between communities that were very segregated and children who had more elevated blood lead levels,” Miranda said. “When we look at the data for 2015 we see, unfortunately, that relationship has persisted.”

😩😩😩 We estimate that at least 151 million cases of diagnosable mental disorder that the population would have experienced over the last 75 years could be attributable to lead,” said Aaron Reuben, a new assistant professor of psychology at UVA and a study co-author. The cases, he said, “would not have existed were it not for the addition of lead to gasoline,” ostensibly to improve engine performance.

“If you look at the current population, Generation X likely had the highest exposures, en masse, of any U.S. generation.”

The study found people born during the era of leaded gasoline are expected to have experienced in their lives “a greater risk for attention deficit hyperactivity disorder, greater risk for psychosis and thought disorders, greater risk for externalizing conditions like antisocial behavior, and internalizing conditions like anxiety, depression,” Reuben said.

😒😒😒 Lead poisoning can have detrimental effects on neurodevelopment, potentially impacting cognitive function as well as behavioral and emotional well-being. Understanding these consequences is crucial in recognizing the potential connection between lead poisoning and autism spectrum disorder (ASD).

Cognitive Effects of Lead Exposure
Excessive lead exposure has been associated with various cognitive impairments in children. Studies have shown an inverse relationship between increased blood lead levels and intelligence scores, with a 4.6-point decline in IQ scores associated with a 10 μg per deciliter increase in average blood lead concentration. This decline in intelligence scores highlights the potential cognitive damage caused by lead exposure.

Furthermore, lead exposure has been linked to decreased memory performance, including difficulties with spatial memory and learning. These challenges can impact a child's ability to acquire new knowledge, retain information, and perform well academically.

Behavioral and Emotional Consequences
In addition to cognitive effects, lead exposure can also contribute to various behavioral and emotional problems. Children with a history of lead poisoning may experience learning disabilities, delayed speech acquisition, and other educational difficulties. These challenges can significantly impact their overall development and ability to interact with others.

Social withdrawal is another common consequence of excessive lead exposure. Lead-exposed individuals may exhibit higher levels of shyness, anxiety, and social withdrawal, making it more challenging for them to form and maintain relationships. These behavioral and emotional consequences can have a profound impact on a child's quality of life and overall well-being.

😩😩😩 Based on both strategies, the researchers found that more lead exposure increased cities’ homicide rates. Cities that used lead pipes had homicide rates 24 percent higher than in cities without lead pipes, on average; places with more acidic water saw bigger increases.

Removing lead from gasoline reduced violent crime

Evidence from the mid- to late-20th century also supports the hypothesis that lead exposure increases criminal behavior. During those years, the primary source of exposure to lead was from leaded gasoline; the lead was released into the air with car exhaust and then settled into soil near the roads.

😟😟😟 A new study calculates that exposure to car exhaust from leaded gas during childhood altered the balance of mental health in the U.S. population, making generations of Americans more depressed, anxious and inattentive or hyperactive. The research estimates that 151 million cases of psychiatric disorder over the past 75 years have resulted from American children’s exposure to lead.

The findings, from Aaron Reuben, a postdoctoral scholar in neuropsychology at Duke University, and colleagues at Florida State University, suggest that Americans born before 1996 experienced significantly higher rates of mental health problems as a result of lead, and likely experienced changes to their personalities that would have made them less successful and resilient in life.

Leaded gas for cars was banned in the U.S. in 1996, but the researchers say that anyone born before then, and especially during the peak of its use in the 1960s and 1970s, had concerningly high lead exposures as children.

😒😒😒 Ohio ranks third in the nation for the highest number of lead pipes, with approximately 745,000 lead service lines still in use, accounting for over 8% of the national total. Proposed legislation aims to replace all of Ohio's lead pipes within 15 years to combat serious health risks to children and adults.

Lurking under the yards and sidewalks of houses across Ohio are lead pipes that deliver potentially dangerous drinking water to hundreds of thousands of families.

😪😪😪 “What's going on in Cleveland is our lead poisoning rate is the highest in the country,” Dr. Dave Margolius, the city’s public health director, said. “You know, nearly one in five children are testing positive for lead poisoning.”

Margolius said lead is a neurotoxin that causes irreversible brain damage to babies who are exposed to it. The department reports more than 1,300 children tested for elevated blood lead levels in 2024.

Over the past five years, city leaders have worked to address Cleveland’s lead crisis through legislation and executive orders that require property owners to register their properties as lead safe. Regardless, the rate of lead poisoning has hovered around 20% since 2019.

☹️☹️☹️ Global estimates suggest that 1 in 3 children worldwide have elevated blood lead levels (UNICEF & Pure Earth, 2020). In 2015, Flint, Michigan made national news when elevated levels of lead were found in the drinking water resulting in high childhood blood lead levels across the city (Pell & Schneyer, 2016). While Flint garnered national attention, in the United States alone there are close to 3,000 cities with lead poisoning rates double those measured in Flint during the water crisis. More than 1,100 of these communities had a rate of elevated blood tests that were at least four times higher than Flint (Pell & Schneyer, 2016).

Lead is a well-known neurotoxicant, with there being no safe level of lead exposure in children (Ruckart et al., 2021). Since children’s brains are still developing, they are particularly vulnerable to lead exposure. Even small amounts of lead exposure in childhood is associated with poor neurocognitive and cardiometabolic outcomes such as lower IQ scores (Heidari et al., 2022), increased aggression (Tlotleng et al., 2022), and elevated blood pressure (Zhang et al., 2012). Furthermore, the effects of lead exposure appear to be long-lasting. For example, chronic lead exposure in childhood has been associated with reduced brain volume in adults (Cecil et al., 2008).

Flint Is in the News, but Lead Poisoning Is Even Worse in Cleveland

CLEVELAND — One hundred fifty miles northwest of here, the residents of Flint, Mich., are still reeling from the drinking water debacle that more than doubled the share of children with elevated levels of lead in their blood — to a peak, in mid-2014, of 7 percent of all children tested.

Clevelanders can only sympathize. The comparable number here is 14.2 percent.

The poisoning of Flint’s children outraged the nation. But too much lead in children’s blood has long been an everyday fact in Cleveland and scores of other cities — not because of bungled decisions about drinking water, but largely because a decades-long attack on lead in household paint has faltered. It is a tragic reminder that one of the great public health crusades of the 20th century remains unfinished. - (By Michael Wines, New York Times March 3, 2016 )

Until now!
