This study tested a program to reduce pesticide exposure in 85 California child care centers serving preschool children. Researchers taught staff safer pest control methods and measured changes in pesticide levels in dust and children's wristbands. The goal was to lower children'…

This study looks at whether receiving personal air pollution monitoring results can change how families understand air quality and their attitudes toward science and research. Participants—children and their caregivers who previously took part in the EcoMAPPE study—will answer qu…

This study looks at whether a big investment in Black neighborhoods—like cleaning up vacant lots, fixing abandoned houses, planting trees, and offering financial counseling and cash help—can improve children's health. Researchers are working with 221 families in Philadelphia. The…

This study investigates whether environmental and occupational exposures influence the risk of developing tumors in people who carry an SDHx gene mutation. Researchers will compare two groups of mutation carriers: those who have had a tumor and those who have not. The goal is to …

This study in rural Guatemala tests whether community education can reduce the burning of plastic waste and lower people's exposure to harmful pollutants. About 400 women and community members from 16 villages will take part, with half attending 12 weekly working groups on waste …

This pilot study tested educational materials designed to help Black community members learn about and reduce exposure to endocrine-disrupting chemicals (EDCs). Researchers worked with community groups to create culturally appropriate online lessons and tracked changes in partici…

This study examined how indoor air quality impacts breathing symptoms and lung function in 165 school-aged children (6-12 years old) who were born prematurely and have bronchopulmonary dysplasia (BPD), a chronic lung disease. Researchers measured respiratory symptoms and lung fun…

This study looked at 69 women who had a pregnancy affected by spina bifida to understand how folic acid might prevent the condition. Researchers measured changes in DNA methylation and folate levels after a short course of folic acid supplements. The goal is to uncover the biolog…

This study looked at whether exposure to PFAS chemicals (found in some water supplies) can weaken the body's immune response to the tetanus and diphtheria booster vaccine. Twenty adults from a community with known PFAS exposure received the vaccine and had blood and saliva sample…

This study looked at teeth from 14 adults living in areas with high or low rates of Crohn's disease. Researchers measured metals and other environmental chemicals in the teeth to see if differences might help explain why some areas have more Crohn's disease. The goal was to gathe…

This study tested an indoor air pollution intervention called AIRWISE in 20 adults aged 55 and older with heart disease. Participants received personal air cleaners, a color-changing air quality monitor, and educational materials. The goal was to see if they would use these tools…
