Figure 3. Hazard quotients (HQs) for estimated infant exposure to organochlorine pesticides (OCPs; A), polychlorinated biphenyls (PCBs; B), and polybrominated diphenyl ethers (PBDEs; C) via breast milk. An HQ > 1 (red dashed line) indicates a potential health risk. For each boxplot, the box limits represent the 10th and 90th percentiles, the whiskers extend to the 5th and 95th percentiles, the interior line marks the median, and the square denotes the mean. Individual data points are plotted. Concentrations below the LOQ were imputed as (DF * LOQ) for the calculation of EDI and subsequent HQ values. Only compounds with DF% > 30 were presented in Figure 1. HCB: Hexachlorobenzene; LOQ: limit of quantification; DF: detection frequency; HCB: hexachlorobenzene; HCH: hexachlorocyclohexane; Drins: a group of related insecticides (i.e, Aldrin, Dieldrin, Endrin); DDX: a collective term for DDT and its metabolites (e.g., DDE, DDD).
