ICP-MS assessment of elemental impurities and metallic contaminants in activated charcoal products.

Activated charcoal is an adsorbent material which is consumed as a dietary supplement (100 mg) and as non-specific antidote treatment in acute poisoning at 0.5-1 g kg body weight in infants and 50 g in adults. The ingestion of large quantities of it has aroused our interest in the presence of metals impurities.

Evaluation of trace metallic element levels in coffee by icp-ms: a comparative study among different origins, forms, and packaging types and consumer risk assessment.

Trace elements (TE) contamination of foods and beverages constitutes a public health issue. In this context, the main objective of this study was to determine metals and metalloids content in coffee and to assess the health risks associated with contaminated coffee consumption. To this end, 44 samples of coffee from different origins, forms, and packaging types were analyzed.
