1. Dietary risk assessment of fluoride, lead, chromium, and cadmium through consumption of Tieguanyin tea and white tea
Abstract Food and beverage consumption is the most possible route of human exposure to undesirable elements. Tieguanyin tea and white tea are widely-consumed beverage, which may be contaminated by fluoride (F), lead (Pb), chromium (Cr), and cadmium (Cd). For this study, the contamination levels and dietary exposure risks of these elements were studied from 7

2. Telepsychiatry in Brazil during the COVID-19 pandemic: Did we exchange a walk-on part in a war for a lead role in a cage?
Abstract Wheat and rice constitute important cereal crops and any contamination may pose potential adverse impacts on human health. The study was conducted to determine eight trace metals, i.e. cadmium (Cd), copper (Cu), cobalt (Co), chromium (Cr), zinc (Zn), lead (Pb), nickel(Ni), manganese (Mn), in wheat, rice and soil samples collected from different citi

4. Quantification of Arsenic, Cadmium, Mercury and Lead in Pineapple: Method Development, Validation and Evaluation of In-House Reference Materials
A method for quantification of arsenic, cadmium, mercury, and lead in pineapple using inductively coupled plasma-mass spectrometry (ICP-MS) was developed, validated, and used to test the homogeneity and stability of in-house reference materials. The method was tested at the regulation levels given by the Food and Agriculture Organization of the United Nation

5. CANTILEVER NANOBIOSENSOR BASED ON THE ENZYME UREASE FOR DETECTION OF HEAVY METALS
Abstract Cantilever nanobiosensors have emerged as an alternative to conventional methods of analysis to monitor heavy metals, which are being highlighted by detecting substances at the micro and nanoscale through the use of sensor layers. In the present study, a new cantilever nanobiosensor was developed functionalized with urease enzyme by self-assembled m

6. Obtaining and characterization of anthocyanins from Euterpe oleracea (açaí) dry extract for nutraceutical and food preparations
Abstract The main constituents of the Euterpe oleracea Mart., Arecaceae, fruits (açaí) are anthocyanins. This paper aimed to standardize the extraction process and characterize an anthocyanin-rich dry extract obtained from this fruit. A 23 full factorial design was used. The volumes of ethanol 92% and acetic acid and the extraction time were used as factor

9. Implantação de protocolo de vigilância e atenção à saúde de ex-trabalhadores e população exposta a chumbo, cádmio, cobre e zinco em Santo Amaro, Bahia
Resumo Introdução: ao longo de 40 anos, estudos evidenciam a contaminação da cidade de Santo Amaro por elevados níveis de chumbo e outros metais. Estudos epidemiológicos revelaram altas concentrações de chumbo e cádmio em amostras de sangue de pescadores, trabalhadores e em compartimentos ambientais. Em 2010, foi instituído um protocolo para orie

10. Minerals multi-element analysis and its relationship with geographical origin of artisanal Mexican goat cheeses
Abstract The objective of this study was to perform a profile of mineral elements and the relationship of those as markers of geographical origin of artisanal goat cheese from the State of Veracruz, Mexico. In fresh and mature goat cheeses the quantified elements were: heavy (aluminum, arsenic, cadmium, lead), major (calcium, potassium, sodium, magnesium), e

12. Evaluation of zinc removal and compressive strength of self-reducing pellets composed of Electric Arc Furnace Dust
Abstract The amount of Electric Arc Furnace Dust (EAFD) is continuously increasing in mini-mill steel plants. This dust is considered a hazardous waste because of the presence of elements like lead, cadmium and chromium. Among many different treatment processes for this issue, there is the possibility of returning the EAFD back to the Electric Arc Furnace. T
