Objective:
The research objectives are listed as follows: Objective 1: Integrate, adapt, and validate standardized protocols for measuring PFAS in multiple media, including biological, water (domestic water and commercial drinking water) dust, personal care products, silicone wristband, and air; Objective 2: Quantify levels of PFAS in 100 previously collected dust and air samples and 40 prospectively collected water, dust, and air samples from the homes, including 40 dried blood spot and personal silicon wristband samples in an existing African American birth cohort in Atlanta GA, where serum levels of some PFAS are higher than US population averages; Objective 3: Estimate the potential contribution of food, food packaging, personal care products, water, dust, and air PFAS to overall body burden using measured dust and air levels, dietary data, personal care product data, and other environmental pathway data in an existing African American birth cohort in Atlanta, GA.
Progress Summary:
Upon receiving IRB approval, our research team is now prepared to begin outreach activities. We anticipate that the participant recruitment will commence in late October 2023 and will last approximately 2 months (1st visit). We will also begin sample collections at the same time as the participants are recruited. Because of the delay in the participant recruitment for the 1st visit, we anticipate the delay in research activities set out in the 2nd visit. In addition, we have also started working on other research activities as proposed. This includes the development of standardized protocols for multi-media measurement of PFAS. We also began quantifying PFAS levels in dust, air, and water samples.
Future Activities:
We plan to continue our research work as proposed. The future research activities include completion of the standardized protocols for analysis of PFAS in multiple media, participant recruitment, sample collections (both visits), and analysis of PFAS in multiple media to estimate the potential contribution of food, food packaging, personal care products, water, dust, and air PFAS to overall body burden.
