Appendix D Food Codes for NHANES - OEHHA

Scientific Review Panel Draft February, 2012
No data could be located regarding dermal or oral absorption of MDA bound to
soil. In addition, no oral bioavailability studies for MDA bound to soil could be
located. Soil fate studies indicate that MDA binds strongly to soil, which would
likely reduce dermal absorption considerably, and biodegrades slowly over a
year’s time. Thus, the default absorption value of 10% for organic compounds is
recommended until soil-bound dermal studies are available.
F.5 Comparison with Other Published Dermal Absorption Factors
Two other agencies have published fractional dermal absorption estimates for
some of the Hot Spots chemicals presented in this document. These values are
shown in Table F.5 and are compared with the fractional dermal absorption
values developed by OEHHA.
