Silva, Karine Aparecida Louvera; Fernandes, Isabela da Costa; Bearzoti, Eduardo; Milani, Raquel Fernanda; Morgano, Marcelo AntonioThe impact of soapstone (steatite) upon inorganic element contaminant concentrations in alcoholic beverages was investigated. Concentrations of As, Cd, Cu, Ni and Pb levels in 8 Brazilian spirits plus an alcoholic simulant were initially measured, and then measured following each 24 h cycle of exposure to raw soapstone cups, for a total of 4 cycles/sample. The results were compared to the levels established by ...

Fernandes, Isabela da Costa; Fausto, Maria Arlene; Bezerra, Olívia Maria de Paula Alves; Quintaes, Késia DiegoThe levels of inorganic contaminants (As, Cd, Cu, Ni and Pb) were measured in 18 Brazilian spirit beverages, before and after 4 contact cycles of 24h each with in natura soapstone (steatite) cups. Results were compared to Brazilian regulation levels. Spirits contained As, Cd, Ni and Pb within permitted levels. For Cu, 5.6% of the brands were above the limit. The contact with soapstone cups decreased Cu levels i...

Sá, Júlia Sommerlatte Manzoli de; Fernandes, Isabela da Costa; Moreira, Daniele Caroline Faria; Milani, Raquel Fernanda; Morgano, Marcelo AntonioIntroduction: The levels of cadmium (Cd) and lead (Pb) in foods should be monitored as a function of health risks. Objective: To evaluate Cd and Pb levels in oral hospital diets and in an oral food complement (OFC) according to their respective consumption by patients, and to estimate the patient’s exposition risk. Methods: The levels of Cd and Pb were determined by ICP-OES in samples of regular, blend, soft an...
