- Abstract
The objectives of this study were to assess levels of contamination of breast milk (BM) by cadmium (Cd) among lactating mothers from Rabat, Morocco, and to investigate its association with several maternal habits, parameters, and factors. In addition, to estimate the daily intake of the newborns. Cd concentrations were measured by inductively coupled plasma-mass spectrometry (ICP-MS) in 70 human milk samples collected between the 2nd and 5th day postpartum. Accuracy of the analysis was checked by various methods including the use of reference material. A structured questionnaire was filled during the collection of milk reporting data concerning anthropometric, sociodemographic parameters, dietary and cosmetic habits, etc. The median (range) of Cd in human milk was 0.49 μg/L (range 0.013–95.19 μg/L) respectively. In 21 (30%) of 70 samples, Cd levels were higher than the normal reported by the World Health Organization (WHO) in BM (< 1 μg/L). Indeed, several factors affect significantly Cd levels in BM of the mothers such as low maternal education level, preterm delivery, cesarean delivery, and area of residence. Also, the frequency of consumption of milk and dairy products as well dried fruits and wheat bread and the frequency of use of cosmetic powders. However, the daily intake of cadmium by the newborns was lower than tolerable daily intake of the WHO for 97% of them. Our results revealed low cadmium concentrations in human milk samples from Moroccan lactating mothers living in Rabat, also the association of some factors with the levels of contamination found in this population.
