The concentrations of 27 trace elements were determined in four meats: beef, pork, ham, and chicken. Because the concentrations of most of these elements were expected to be very small, the extremely sensitive method of neutron activation analysis was used in this study. Qualitative analyses were performed for 8 of the elements, and the concentrations of 19 elements were determined quantitatively. The quantitatively measured concentrations varied from ∼0.1% for phosphorus to ∼10−5 ppm for cerium. Most …
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
