Data on fatty acid profile, optical properties and oxidative stability of sunflower oils used in the treatment of skin wounds.

This dataset describes the analysis of aflatoxins, macroelement and microelement concentration, oxidative stability and fatty acid profile of infant formula milk powder. Gas chromatography (CG) was used to identity 14 fatty acid methyl esters in in five samples of oils. The Racimat 893 method (induction times), Thermogravimetry (TG), Derivative Thermogravimetry (DTG) and Differential Scanning Calorimetry (DSC) were used to estimate the oxidative stability of oils. In addition, UV-VIS spectroscopic techniques were employed to obtain graphs of the absorption of each oil. The data presented can be useful in identifying compounds available in oils used to promote wound healing and understand the degradation mechanism.

Bioaccumulation, genotoxicity, and risks to native fish species from inorganic contaminants in the Pantanal Sul-Mato-Grossense, Brazil.

The Aquidauana River is one of the most important rivers in the Pantanal region, Brazil. However, its waters have been contaminated by nearby anthropogenic activities, threatening native fish species. In this study, our objectives were: 1) to determine the concentrations of Al, As, Cd, Cu, Fe, Mn, Ni, Pb, and Zn in water and sediment samples from the Aquidauana River and to assess the risks posed to aquatic biota; 2) to quantify the concentration of these elements in muscle and liver tissue samples from four native fish species; 3) to evaluate the potential bioaccumulation of inorganic elements in the muscles and liver; and 4) to investigate genotoxicity biomarkers and their association with the inorganic element concentrations present in the muscle tissue. Water and fish samples were collected in November 2020. The concentrations of Al, As, Cd, Cu, Fe, and Pb in the water samples were in disagreement with the Brazilian legislation and presented risks to the aquatic biota. In terms of mixtures of inorganic elements, there was a great increase in the risk to biota. The As concentration did not meet the Brazilian standard for sediments in the sample collected at sampling site 6. The concentrations of Cd and Pb in the muscle tissue of Hypostomus regani, Prochilodus lineatus, Brycon hilarii, and Mylossoma duriventre exceeded the Brazilian standards for human consumption. H. regani showed greater genotoxic damage, and the higher the Al and Fe concentrations in the muscle tissue, the higher the frequencies of lobulated nuclei and nuclear invaginations. Together, our results demonstrate the negative impacts on native fish species from the Aquidauana River contamination and indicate risks to Pantanal biodiversity.

Exposure to Toxic Metals and Health Risk Assessment through Ingestion of Canned Sardines Sold in Brazil.

The presence of heavy metals in the environment is increasing, which can be a danger to public health. Fish exposed to contaminated environments tend to have higher concentrations of some metals in their tissues. Monitoring these elements remains urgent as it is a matter of global concern. Canned sardines from the Brazilian market were analyzed for elements (Al, As, Ba, Cd, Co, Cr, Cu, Fe, Ni, Pb, Se, and Zn) of metals and metalloids, including some toxic, using inductively coupled plasma optical spectrometry (ICP OES) in two types of sardines (preserved in oil and tomato sauce) from five different brands. The results were compared to limit levels for consumption set by FAO/WHO. Moreover, we assessed the associated risk regarding the elemental intake of these elements through the samples, using the hazard quotient (HQ), hazard index (HI), and carcinogenic risk (CR). All samples had unfavorable HQ and HI, primarily due to arsenic content. In the same manner, CR for arsenic was above the proposed limit of 10-4, and cadmium and chromium, which were within the acceptable limit (10-6 to 10-4), require attention. These results show that chronic consumption of canned sardines sold in Brazil is unsafe, and quality surveillance is needed to ensure there is no risk to the population that ingests these products.

Assessment of Trace Elements Supply in Canned Tuna Fish Commercialized for Human Consumption in Brazil.

This study evaluates the elemental content in 4 types of canned tuna fish groups, each with 4 brands that are commercialized for human consumption in Brazil. The results are based on trace elements in canned tuna fish quantified by ICP OES and a comparison to limit levels set by the FAO/WHO. We also checked the carcinogenic risk (CR), non-carcinogenic risk (Hazard Index (HI) and Hazard Quotient (HQ)), and pollution index (PI) for the studied canned tuna samples. As and Se concentrations in all groups are above the intake values set by FAO/WHO considering specific groups. The carcinogenic risk values for arsenic (As) in groups are considerably unacceptable (≥10-4). Hazard quotients (HQ) were >1 for As in all groups, while no sample was below 1 for HI. The pollution index (PI) results show that the main canned tuna fish contaminant is aluminum, then selenium and arsenic, respectively. Only half of the samples did not present elemental contaminant levels. All studied brands of canned tuna presented elemental concentrations that could pose a health risk to human consumption, that could be from CR, HQ, HI, or PI. The contaminant levels are alarming and should raise a red flag for the intake of these products, especially a long-term one. These results urge the authorities to supervise and enforce better practices for this type of food, protecting their population from health hazards.

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.
