serum concentrations of pfass and exposure-related behaviors in african american and non-hispanic white women
Per- Fluorine-containing substances (PFASs) Is widely consumed in the water of productsand grease- But few studies have explored this exposure pathway. We use multiple regression to investigate the association between the six selves. Reported behavioral hypothesis affects PFAS exposure and serum concentration of six PFAS chemicals in 178 Older women who participated in research on children\'s health and development accounted for about half of African-Americans. Blood samples were collected 3-10, and participants were interviewed on behavior in 1-15. The results showed that the total fluoride content of African-American women was low (PFOA) And peracid (PFHxS) Non- White Hispanic woman In African-Americans, not others, eating prepared food in coated cardboard containers is often associated with a high level of the four PFASs. Clean dental floss with mouth B. sliding with stains Resistant to carpets or furniture, living in a city serviced by PFAS The contaminated water supply is also related to higher PFASs levels. Product testing using particlesinduced γ-ray emission (PIGE) Spectrum confirmed oral- B Glide and rival flo contain detectable fluorine. Despite the delay between blood collection and interviews, these results reinforce the evidence of exposure to PFASs from food packaging and suggest exposure to PFASs from polytrifluoride (PTFE)- Floss is used for the first time. Per- Fluorine-containing substances (PFASs) It is a group of commercially important chemicals with a wide range of applications, because they have a unique ability to resist water and lipids. In addition to professional industrial applications and use in fire protection PFASs is often used against bubbles in consumer goods. Most often, they are used for non-stick and water-, stain-, or grease- It is suitable for coating resistance of various products such as food packaging, cookware, carpet, furniture, textiles and outdoor performance equipment. Given the widespread use and persistence of PFASs, it is not surprising to detect PFASs in [water] and soil] In the body of almost all Americans]. Exposure for a long time Chain PFASs all fluorine bitter acid (PFOA) And all fluorine bitterness (PFOS) Related to kidney and testosterone cancer, decreased semen quality and uc in adults [,,] Effects on thyroid disease, immune response and reduced sex and growth hormone in children [,,]. The serum PFAS levels in the general population vary from race to race. Multi-cycle data analysis of National Health and Nutrition Examination Survey (NHANES) Consistent differences in PFAS exposure by race. Difference between non Hispanic whites and blacks differ from chemical substances, white people have higher PFOA levels, and black people have higher levels of perfluoronanoic acid (PFNA) To a lesser extent, PFOS [,,,]. These differences remain after controlling household income . In the Viva project Study of 6-10-year-old children born in Boston area The PFOA, PFOS, and perf-Hexic acid levels of children of black mothers are low (PFHxS), and 2-(N-methyl- ()acetic acid (Me-PFOSA-AcOH) , But compared to the children of white mothers, even after adjusting the concentration of the mother during pregnancy, there is no choice for the reference . The factors contributing to these observed differences by racial differences are not clear, but may be due to the differences in exposure -- Related behaviors and communitiesHorizontal exposure. Environmental pollution, including dietary-mediated exposure, is an important factor in individual PFAS levels, even in communities not directly affected by industrial operations. In a study by women in California, drinking water supply detected a median increase of 38 and 29% in serum chemicals in participants with PFOA and PFOS concentrations, respectively, compared with participants who do not have detectable concentrations in drinking water ,. Fish and shellfish widely contaminated by PFASs [, ] , Seafood consumption related to PFAS level [, ]. Other unprocessed foods (e. g. Vegetables, meat, eggs) Usually contains a lower PFASs level than fish and shellfish [, ]. PFASs and its predecessor are widely used in various consumer goods. For food packaging and contact materials [,,,,] Can be migrated to food during typical use and preparation [, ,,]. PFASs also exists in the indoor environment [, ] They are released into the dust of air and consumer goods. Fabrics including clothing and uniforms, home and outdoor textiles, carpets and upholstered furniture are commonly treated with PFASs before sale, and many cleaning and handling products also contain PFASs [, , ]. Other consumer goods known to contain PFASs, as per product testing, include dental floss, non-stick cookware, ski and wax, and threaded sealing tape [, , ]. Given the large number of sources of PFASs in the daily diet and environment, it is difficult to determine which behaviors contribute the most to PFAS exposure. Many studies focus only on dietary sources [, , , , , ]. So far, two studies have tried to link diet to non-diet Measurement of dietary sources of exposure levels [, ]. Harris et al. In an analysis of 545 children in the Viva program, sleep was found ( But not awake) In carpeted rooms, PFOS, PFHxS, and Me-PFOSA- AcOH, mixed association with outdoor time and PFAS level according to season, and with high fast- Food consumption and ammonium trifluoride, and I. PFOSA- AcOH, adjusted according to the features of the child and mother . Wu et al. analyzed 68 children and 149 adults living in the California Central Valley. In addition to dietary predictors, a positive correlation was found between occupational exposure to adults or the use of fire extinguishers and PFOA, DHS, PFHxS, and PFOS levels, and a positive correlation between children wearing waterproof suits and PFOS [1 . No association was found with the housing properties or the use of non-stick cookware, stains Or polished and coated products. These studies provide preliminary insights into the product and behavioral contributions exposed by PFAS, but additional data are needed to assess differences through contributions of race and previously unstudied behaviors. In this paper, we study the role of self. Reported use of consumer goods predicted exposure levels of six PFAS chemicals in a medium population Half of the elderly women are African-Americans. We include the same exposure as the previous analysis (e. g. Consumption of microwave popcorn) For the first time, consider exposing from the mouth. Flossing. We also provide data on oral fluoride B. taxiing and other dental floss as an indicator of polysifluoride (PTFE) In these products This study extends the work of consumer product exposure to PFAS and evaluates whether consumer behavior varies through racial regulation of PFAS exposure.
