Supporting Knowledge and/or Skills

a. Describe the significance of instrument calibration and operation and data collection

methods during sampling.

b. Describe how multiple exposures affect sampling techniques.

c. Describe the factors (e.g., concentration, duration, frequency) that determine the

adequacy of samples

d. Describe how environmental factors (e.g., wind, rain, temperature extremes) affect

the need for further sampling.
