Type of measurement (sample)

Examples

Typical information needed to characterize exposure

6. Consumer Products

Shelf surveys, e.g., solvent concentration in household cleanersf

Establish use patterns and/or market share of particular products, individual exposure at various usage levels, extent of passive exposure.

7. Breathing Zone Measurements

Industrial hygiene studies, occupational surveys, indoor air studies.

Location, activities, and time spent at monitoring locations. Protective measures/avoidance.

8. Microenvironmental Studies

Special studies of indoor air, house dust, contaminated surfaces, radon measurements, office building studies.

Activities of study populations relative to monitoring locations and time exposed.

9. Surface Soil Sample

Soil sampling at hazardous waste sites.

Fate of pollution on/in soil; activities of potentially exposed populations.

10. Soil Core

Soil sampling at hazardous waste sites

Fate of substance in soil; speciation and bioavailability, contact and ingestion rates as a function of activity patterns and age.

11. Fish Tissue

National Shellfish Surveyg

Relationship of samples to food supply for individuals or populations of interest; consumption habits; preparation habits.

B. For Use in Point-of-Contact Measurement

1. Air Pump/ Particulates and Vapors

TEAM study,h carbon monoxide,i Breathing zone sampling in industrial settings.

Direct measurement of individual exposure during time sampled, including relationships between individual and the population.

 

 

Exposures, relationships between concentrations at times sampled and at other times and relationship between sampled individuals and other populations. To make these links, activities of the sampled individuals compared to populations characterized are needed in some detail
