(Press-News.org) PROVIDENCE, R.I. [Brown University] — Childhood lead exposure, primarily from paint and water, is a significant health concern in the United States, but a new study has identified a surprising additional source of lead exposure that may disproportionately harm children: firearms.
A team led by researchers at Brown University found an association between household firearm ownership and elevated lead levels in children’s blood in 44 states, even when controlling for other major lead exposure sources.
Lead exposure from firearms is far less explored than from recognized sources like water or lead-based paint, but may be equally dangerous for children’s health, said Christian Hoover, a Ph.D. candidate in epidemiology at Brown’s School of Public Health, who is the lead author of the study published in the Journal of Pediatrics.
“This is very concerning because we don’t have a system of monitoring lead from firearm use, as we do with residential paint, and there is no system in place to minimize or prevent children’s exposure to lead in firearms,” Hoover said. “Firearm use is a relatively unchecked source of childhood exposure to lead. There’s currently no way to stop the exposure from happening and no interventions when it does.”
In the study, the association between elevated lead levels and firearm use was almost as strong as the association for lead-based paint, Hoover noted.
Lead levels in children in the United States have been persistently high for decades. While public health measures have been put in place to prevent and reduce childhood lead poisoning from paint and drinking water, blood lead levels haven’t concordantly dropped in significant measures, Hoover said.
Firearm-related take-home lead occurs when an individual discharges a firearm that uses lead-based ammunition and primer, which are the most commonly used in the United States, Hoover said. The lead dust settles on clothes and personal items, such as phones or bags, as well as in vehicles and common spaces. Children are more vulnerable to lead than adults due to their tendency to ingest contaminants through normal hand-to-mouth behaviors.
“Typically the places where the firearm-related lead collects, such as in carpets, are places where young children spend a considerable amount of time,” said Hoover, who is a co-investigator at the Harvard Injury Control Research Center.
A previous study led by Hoover found a link between firearms and elevated lead levels in children’s blood in cities and towns in Massachusetts; this new study involved the 44 U.S. states that report public health data on child blood lead levels.
Since there is no governmental database covering firearm ownership across states, the researchers used a widely-accepted proxy measure developed by the RAND Corporation to estimate state levels of household gun ownership. This metric combines data on firearm suicides, hunting licenses, subscriptions to Guns and Ammo magazine and background checks. They compared the data from the proxy measure with reports from the Centers for Disease Control and Prevention of blood lead concentration surveillance data for children under 6. The analysis spanned the years between 2012 and 2018.
According to the study, for every 10% increase in the number of households that report owning a gun, there is an approximate 30% increase in cases of elevated pediatric blood lead levels.
Childhood exposure to lead increases the risk of behavioral problems, reduced cognitive abilities and poor growth and development. There is no safe level of lead exposure, said Joseph Braun, a professor of epidemiology and director of the Center for Children’s Environmental Health at Brown.
“Despite public health efforts to prevent or reduce childhood lead exposure, a substantial proportion of U.S. children are still exposed,” Braun said. “Thus, we need to identify other modifiable sources of lead exposure in children’s environments to protect their developing bodies and brains.”
The authors concluded that the data suggest firearms are a notable source of child lead exposure that requires more targeted research.
Alan Fossa, a postdoctoral research associate in environmental health at Brown, also contributed to this study.
This research was supported by the National Institute of Environmental Health Sciences (R21 ES034187).

Discovered a RNA molecule that helps prevent DNA replication errors
2024-03-04
Researchers at Cima Universidad de Navarra have discovered that a ribonucleic acid that does not contain information to make proteins (long non-coding RNA) plays a crucial role in signalling and repairing errors in DNA replication during cell division. This finding could lead to the development of new anti-tumour therapies.
Scientists have identified an RNA that they named 'lncREST' (long non-coding RNA REplication STress) and uncovered its role in triggering an effective response to the stress induced by rapid cell division. "LncREST localises ...
Small and overlooked: Amount of repetitive DNA in blood hints at cancer early
2024-03-04
FOR IMMEDIATE RELEASE
People with cancer have different amounts of a type of repetitive DNA — called Alu elements — than people without cancer. Now, machine learning can measure that from a blood draw. Researchers at the Johns Hopkins Kimmel Cancer Center have used this finding to improve a test that detects cancer early, validating and reproducing the results by starting with a sample size tenfold larger than typical of such types of studies.
The research was published Jan. 24 in the journal Science Translational Medicine.
Alu ...
Study determines the original orientations of rocks drilled on Mars
2024-03-04
As it trundles around an ancient lakebed on Mars, NASA’s Perseverance rover is assembling a one-of-a-kind rock collection. The car-sized explorer is methodically drilling into the Red Planet’s surface and pulling out cores of bedrock that it’s storing in sturdy titanium tubes. Scientists hope to one day return the tubes to Earth and analyze their contents for traces of embedded microbial life.
Since it touched down on the surface of Mars in 2021, the rover has filled 20 of its 43 tubes with cores of bedrock. Now, MIT geologists have remotely determined a crucial property of the rocks collected to date, which will help scientists answer key questions about the planet’s ...
Illinois study: Supporting disease-challenged broiler chickens through nutrition
2024-03-04
URBANA, Ill. — When broiler chickens are busy fighting the parasitic infection coccidiosis, they can’t absorb nutrients efficiently or put energy toward growth. With consumer sentiment pitted against antimicrobials and other drugs, producers still have some options to ensure optimal growth during inevitable outbreaks. New research from the University of Illinois Urbana-Champaign suggests diet changes might help.
“Vaccines and anticoccidials are the traditional ways to prevent this disease. Nutrition can't replace all of the pharmaceuticals, but it can be supportive in providing care,” said senior study author Ryan Dilger, ...
