To determine which of the selected environmental chemicals detected in blood in the NHANES survey by CDC can be detected and measured in the serum and urine tissue, as well as the change over time in the detected environmental toxin levels in the blood and urine of patients who undergo bariatric surgery and experience significant weight loss.
To demonstrate that a passive wristband sampler can be used to quantify personalized exposure to environmental chemicals such as polycyclic aromatic hydrocarbons (PAHs) with higher compliance and equal accuracy compared to an active air sampler, and to show the utility of a mobile phone-enabled application to concurrently capture lung function measurements.

To study the temporal variability of phenol urinary concentrations during pregnancy, focusing on the between-day and between-trimester variability. The study will identify the efficiency of within-subject pooling of biospecimens to characterize the mean urinary levels of phenols during pregnancy.
To assess the feasibility of collecting urine and blood specimens from women who enroll in the Boston University Pregnancy Study Online program and to characterize the distribution of urinary bisphenol A (BPA) and phthalate-metabolites and serum-perfluorinated chemicals in collected urine and blood specimens.
