While major pathways of human PFAS exposure are thought to be drinking water and diet, other sources have also been shown contribute a person's cumulative exposure. However, the degree contribution these body burdens is still not well understood occurrence data for in conssumer products household materials sparse. Questionnaire concordant with biomonitoring may improve understanding associations between populations.This study aims better understand maternal early-life exposures from various...
Per- and polyfluoroalkyl substances (PFAS) are widely used in industry have been linked to various adverse health effects. Communities adjacent sites where PFAS manufactured, stored, or may be at elevated risk. In these impacted communities, significant exposure often occurs through contaminated drinking water, yet less is known about the role of other pathways such as residential house dust. We analyzed a paired serum dust dataset from Agency for Toxic Substances Disease Registry's Exposure...
Most people in the United States have been exposed to per- and polyfluoroalkyl substances (PFAS) which linked a wide array of adverse health conditions adults children. The consumption contaminated drinking water is an important human exposure pathway PFAS. Residential sources also contribute PFAS through dermal contact ingestion house dust, acts as aggregate chemicals from like furnishing materials consumer products. U.S. Department Housing Urban Development (HUD) conducted first nationwide...
Total suspended solids (TSS) is an important environmental parameter to monitor in the Chesapeake Bay due its effects on submerged aquatic vegetation, pathogen abundance, and habitat damage for other life. home extensive continuous network of situ water quality monitoring stations that include TSS measurements. Satellite remote sensing can address limited spatial temporal extent sampling has proven be a valuable tool estuarine systems. Most algorithms derive concentration environments from...
Decision makers in the Columbia River Basin (CRB) are currently challenged with identifying and characterizing extent of per- polyfluoroalkyl substances (PFAS) contamination human exposure to PFAS. This work aims develop pilot a methodology help decision target prioritize sampling investigations identify contaminated natural resources. Here we use random forest models predict ∑PFAS fish tissue; understanding PFAS levels is particularly important CRB because can be major component tribal...
Humans experience widespread exposure to anthropogenic per- and polyfluoroalkyl substances (PFAS) through various media, which can lead a wide range of negative health impacts. Tap water is an important source in communities with any degree contamination but routine or large-scale PFAS monitoring often depends on targeted analytical methods limited measuring specific PFAS. We analyzed 680 tap samples from the American Healthy Homes Survey II for using non-targeted analysis (NTA) expand...
Beer has been a popular beverage for millennia. As water is main component of beer and the brewing process, we surmised that polyfluoroalkyl substances (PFAS) presence spatial variability in drinking systems are PFAS source beers. This first study to adapt EPA Method 533 measure from various regions, brewery types, sources. Statistical analyses were conducted correlate state-reported water, beers analyzed by location. detected most beers, particularly smaller scale breweries located near...
Abstract Global climate during the Holocene was relatively stable compared to late Pleistocene. However, evidence from lacustrine records in South America suggests that tropical latitudes experienced significant water balance variability Holocene, rather than quiescence. For example, a tight coupling between insolation and carbonate δ 18 O central Andean lakes (e.g., Lakes Junín, Pumacocha) suggest is tied directly American summer monsoon (SASM) strength. lake also incorporate information...
Abstract Background The use of systems science methodologies to understand complex environmental and human health relationships is increasing. Requirements for advanced datasets, models, expertise limit current application these approaches by many public practitioners. Methods A conceptual system-of-systems model was applied children in North Carolina counties that includes example indicators children’s physical environment (home age, Brownfield sites, Superfund sites), social (caregiver’s...
Per- and poly-fluoroalkyl substances (PFAS) are chemicals of concern-they ubiquitous, persistent, with known suspected health impacts. Well studied, primary sources exposure to PFAS drinking water food. The presence in human tissue general populations suggests other important sources/pathways. House dust measurements suggest widespread residences. Limited studies report paired analyses occurrence indoor media concentrations serum. While samples house blood serum currently rare, the National...
