Fig. 3

a–c show the annual exposure by season across three methods (1 = daily ingestion rate; 2 = hourly ingestion rate; 3 = hourly task-specific ingestion rate). d, e show the total and relative estimated exposure originating from hours spent indoors vs. outdoors for methods 2 and 3. f shows the total and relative exposure originating from each of six meso-activities using method 3.
