The objective of this study was to determine whether crops and fruits absorb the naturally occurring asbestos (NOA). The concentration of asbestos in various crops and fruits grown in NOA areas was analyzed and background levels of asbestos in ambient air and soil samples were assessed. Actinolite/Tremolite asbestos were detected in all soil samples. Among 21 ambient air samples, 2 samples were recorded to contain 0.0005 f/cc (fiber per cubic centimeter) but no asbestos was detected in the other samples using transmission electron microscopy (TEM). However, no evidence suggesting that the crops and fruits could be contaminated by NOA was found in this study. The excess lifetime cancer risks (ELCRs) of ABS scenarios (agricultural activities) used in this study were calculated by using the Arithmetic (AM) and Geometric mean (GM) of ELCRs. The AM and GM of ELCRs estimated from digging soil and weeding activities did not exceed 1 × 10−4, which was defined as the general acceptable risk range for exposure. The results of this study would be informative to NOA managers and related policy makers to make plans to prevent unexpected exposure to asbestos to residents living in an NOA area.
