EPA study finds that US public schools with the highest potential exposure risk to air toxics have higher proportions of disabled Latino, Hispanic, and Asian children    

2024-12-10
(Press-News.org) EPA study finds that U.S. public schools with the highest potential exposure risk to air toxics have higher proportions of disabled Latino, Hispanic, and Asian children    

Children are at greater risk from inhaled air pollutants than adults, as they have higher respiratory rates. Research has shown that air pollutants in the form of respiratory toxicants (such as some  pesticides and solvents) can represent a significant health risk to children. 

The Environmental Protection Agency (EPA) has completed a nationwide study to assess the estimated non-cancer exposure risks of public school students to ambient air respiratory toxicants. The analysis also examined how disability status, race, and ethnicity were related to exposure risk in more than 88,000 regular public schools located in the 50 states, Washington D.C., and Puerto Rico.  

Research findings will be presented in December at the annual meeting of the Society for Risk Analysis in Austin, Texas. Mariah Amter, Oakridge Institute for Science and Education Research Fellow, will present the study, “Geographic and sociodemographic disparities in estimated potential exposure risks of children to ambient air respiratory toxicants at U.S. public schools,” on December 9 at 6:00 p.m.  

The statistical analysis paired publicly available sociodemographic data for each school with respiratory hazard indexes (HI) at the census tract-level from the 2018 EPA Air Toxics Screening Assessment. Each school was ranked by its respiratory hazard index (HI), or the sum of hazard quotients for 42 different air respiratory toxicants. (The higher the HI, the greater the risk for potential adverse health effects.) The top five percent of schools were selected as “higher exposure risk schools.” 

The analysis compared the proportion of disabled children in these higher exposure risk schools to those in the rest of schools and made a similar comparison based on the racial and ethnic composition of students. 

Research findings: 

The majority of schools with the highest HI are located in California, Colorado, and Louisiana.  

The results indicate there is a significantly higher proportion of racial and ethnic minority children in “higher exposure risk schools” compared to racial and ethnic minority children in the rest of schools.   

There is a significantly higher proportion of Hispanic and Latino children in the “higher exposure risk schools” compared to the rest of schools. 

There is a higher proportion of Hispanic and Latino children with a disability in the “higher exposure risk schools” compared to the rest of schools. 

Going forward, the researchers plan to conduct a similar analysis using 2020 EPA AirToxScreen data taken at the smaller census block level and examine additional sociodemographic variables including poverty and urbanicity.

“Missing link” between brain and body inflammatory signals identified in the skull

2024-12-10
New research from the Institute of Psychiatry, Psychology & Neuroscience (IoPPN) at King’s College London provides valuable insights into the brain-body immune connection identifying key communication hubs in the dural sinuses and skull bone marrow at the back of the head.  The research, which was supported by funding from the National Institute for Health and Care Research (NIHR) Maudsley Biomedical Research Centre (BRC) and published in the journal Brain, used neuroimaging techniques to establish that the dural sinuses, a region at the ...

Online training could help older adults communicate in noisy environments

2024-12-10
Online training that helps people recognise and understand new voices could be key to helping older adults improve communication in everyday environments, finds research by UCL experts. The study, published in the Journal of Experimental Psychology: Applied, tested whether learned voices were easier to understand than unfamiliar voices in 20 older (55-73 years) and 20 younger (18-34 years) adults. Participants took part in some preparatory online training, where they were trained to understand three new voices by listening to them each say 10 meaningful sentences until they became “familiar”. They then had to listen to one of these voices speak ...

Short-term cognitive boost from exercise may last for 24 hours

2024-12-10
Short-term cognitive boost from exercise may last for 24 hours The short-term boost our brains get after we do exercise persists throughout the following day, suggests a new study led by UCL (University College London) researchers. Previous research in a laboratory setting has shown that people’s cognitive performance improves in the hours after exercise, but how long this benefit lasts is unknown. The new study, published in the International Journal of Behavioral Nutrition and Physical Activity, ...

Researchers ‘see’ vulnerability to gaming addiction in the adolescent brain

2024-12-09
Playing video games is a rite of passage for many adolescents, but for some, it could also be the first step to a gaming addiction. “A number one concern for parents of children and teenagers is how much screen time and how much gaming is enough gaming and how to figure out where to draw the line,” said John Foxe, PhD, director of the Del Monte Institute for Neuroscience at the University of Rochester and co-author of a study out today in the Journal of Behavioral Addictions that discovered a key marker in the brain of teens who develop gaming addiction symptoms. “These data begin to give us some answers.” Researchers ...
