| Description | Cadmium and lead are elements commonly found in the environment, heavy metals. They enter the body mainly through the digestive tract (80%). Heavy metals have a toxic effect on the human body and, when accumulated, can cause many changes, including: in the nervous, hematopoietic and digestive systems and have an adverse effect on various organs. Infants and young children are at particular risk due to insufficiently developed detoxification systems. The aim of the study was to determine the content of cadmium and lead in baby food: breast milk and formula infant milk. The research material consisted of breast milk samples collected from 29 residents of the Warmian-Masurian Voivodeship at various stages of lactation. The research material also included commercially available infant formula from two manufacturers, intended for infants in the initial and subsequent feeding period. The study included 6 samples of each type of modified milk. The content of cadmium and lead after dry mineralization was determined using flame atomic absorption spectrometry. No differences were found in the cadmium content in infant formula from different manufacturers and in human milk. The cadmium content ranged from 1.17 to 10.10 µg/100 cm3 of milk. The lead content in infant formula from different manufacturers was at a similar level (range 55.25 - 75.76 µg/100 cm3 of milk). However, in breast milk, lead was determined in the range of 79.25 - 658.75 µg/100 cm3 of milk. |
