Fig. 2. The ∑BAC and ∑ATMAC concentrations (mean ± standard error, ng/mL) in breast milk samples grouped based on mothers’ disinfection habits.

A Levels in breast milk collected from mothers who do (n = 21) vs. those who do not disinfect or use (n = 26) QAC-containing disinfecting products. B Levels in breast milk collected from mothers who use sprays (n = 8) vs. wipes (n = 13). C Levels in mothers who disinfect more frequently (more than once a week, n = 8) vs. those who disinfect less frequently (less than once a week, n = 11).
