Given the low completion rates for the activity logs, the following filtering steps were used: Activity logs were only included in the analysis if at least 5 of 7 days were completed. For each question, there must be a 40% or higher response rate, with at least 40% of responses in the affirmative (e.g., not “no” or “0”). For each sampler (stationary or wristband), the average PAH concentration was calculated, to assess the potential influence of various behaviors on PAH concentrations (e.g., use of heat, use of AC, etc.) * Indicates answers identified via thematic analysis. In total, 11 WB participants and 7 stationary participants completed the daily activity log. P-values were obtained using Welch’s t-tests for yes or no answers and utilizing the average PAH concentrations for participants.
