Appendix D Food Codes for NHANES - OEHHA

Scientific Review PanelSRP Draft Version 2 February,June 2012
Gulson et al (1998a) also suggested that analytical problems, indicated by an
unusually wide range in lead concentrations for the quality control standard in
Parr et al (1991), warrant verification by follow-up studies (Parr et al., 1991;
Gulson et al., 1998a). Gulson et al (1998a) assessed lead concentrations in
maternal blood versus the concentration of lead in breast milk per concentration
in maternal whole blood from studies conducted over 15 years prior to 1998.
From this assessment, they suggested that milk lead levels less than about 15%
of maternal blood lead levels best represent the relationship between lead in
maternal blood and milk. In other words, milk lead levels that were greater than
15% of blood lead levels were suspected of being contaminated with lead during
sample collection and/or assessment. Therefore, OEHHA has included only
summary estimates from studies published after 1990 that did not report or show
evidence of breast milk contamination.
OEHHA located eight studies that met our inclusion criteria. Table J.4-1
summarizes key attributes of the study populations.
