Levels of Aflatoxin M1 and selected heavy metals (Pb, Cd, Cr, Cu, Zn, Fe, As, and Hg) in the breast milk of lactating mothers in South Eastern, Nigeria

Levels of Aflatoxin M1 and selected heavy metals (Pb, Cd, Cr, Cu, Zn, Fe, As, and Hg) in the breast milk of lactating mothers in South Eastern, Nigeria

In this study, the level and frequency of breast milk AfM1 and selected heavy metals as biomarkers of maternal exposure was assessed. Selected heavy metals (Pb, Cd, Cr, Cu, Zn, Fe, As, and Hg) were analyzed using Atomic Absorption Spectrophotometry while AfM1 levels were assessed by HPLC with fluore...

Zusammenfassung:In this study, the level and frequency of breast milk AfM1 and selected heavy metals as biomarkers of maternal exposure was assessed. Selected heavy metals (Pb, Cd, Cr, Cu, Zn, Fe, As, and Hg) were analyzed using Atomic Absorption Spectrophotometry while AfM1 levels were assessed by HPLC with fluorescence detection after aflatoxin extraction. The mean (±standard deviation) concentration of AfM1 in the breast milk samples was 4.02 ± 1.12 ng/L and 100% of all the samples contained AfM1 at 2.33–7.08 ng/L. AfM1 concentration was positively and significantly (p
