Hand Loading Plot
Fig. 11. Geometric means and corresponding 95% confidence intervals for hand loadings for all activity groups. The purple, green, blue, and red symbols signify background (<0.01 mg/cm2), low (0.01-0.1 mg/cm2), moderate (0.1-1.0 mg/cm2), and high (>1.0 mg/cm2) contact categories. The 1992 EPA default range of 0.2-1.0 mg/cm2 is represented by the vertical dashed lines.
