Agricultural workers' exposure to soil contaminants is not well characterized. This study introduces "meso-activity," specific tasks within broader activities, to improve exposure assessment. In-depth interviews with sixteen fruit and vegetable growers in Maryland characterized factors influencing soil exposure. A framework categorizing these factors (Environmental, Activity, Timing, and Receptor; EAT-R) was developed and applied to quantitative exposure models. Results show six meso-activities and ten influencing factors, improving exposure estimates and highlighting variability in agricultural work.
