Data on metals, nonmetal, and metalloid in the samples of the canned tuna and canned sardines sold in Brazil.

The safety of food is a matter of global concern today. Continuous monitoring of canned tuna and canned sardines quality is essential regarding metal, nonmetal, and metalloid content. In this article, we present the data on the elemental content obtained in canned tuna and canned sardines by using inductively coupled plasma optical spectrometry (ICP OES), as well as the data on Pollution Index (PI) and Health Risk Index (HRI). Pollution index and health risk index are tools used to assess elemental contamination in the environment and food. A total of 6 metals (Al, Ba, Ca, Cu, Fe, and Zn), one nonmetal (Se), and one metalloid (As) were quantified in the samples of the canned tuna and canned sardines. For elements as Al, Cu, Fe, and Se, PI > 1. In addition, Cd, Co, Cr, Ni, Zn, and Pb have PI values less than 1. The HRI values for some canned tuna samples were above 1 for elements such as Al, Ba, Ca, and As. For canned sardines, the elements Cr, Ni, and As showed HRI values >1.

Data on ICP OES and emulsion stability of Bredemeyera floribunda root extract: Medicinal plant used by the Brazilian rural population to treat snakebites.

Bredemeyera floribunda Willd (B. floribunda) is a medicinal plant used by the Brazilian rural population to treat snakebites, but there are no data on the elemental composition and stability of the emulsion of extract of this plant. In this article, we present for the first time data on contents obtained the roots of the medicinal plant B. floribunda by using inductively coupled plasma optical spectrometry (ICP OES), as well as the data on preliminary stability tests of emulsions formulated with aqueous extract of this plant. The first set of data shows a total of 13 elements (Al, Ca, Cr, Fe, K, Mg, Mn, Na, Ni, P, Cu, Se and Zn) detected in the roots of the plant. The second set of data shows that the extract data of the B. floribunda roots presented an emulsifying potential. In addition, the article provides information on the heating program for microwave oven digestion and ICP OES operating conditions. The data presented make way for nutritional and toxicological studies involving the roots of B. floribunda. The data on the cataloging of the plant can be found in the deposit nº 54366 of the Herbarium of the Federal University of Mato Grosso do Sul, available in www.splink.org.br/form?lang=pt&collectioncode=CGMS.
