GC×GC in the Characterization of the Bio-Oil from Brazilian Biomass: A Review
Rafael de Oliveira Farrapeira, Yasmine Braga Andrade, Laíza Caniellas Krause, Thiago Rodrigues Bjerk, Elina Bastos Caramão and Jaderson Kleveston Schneider
In this review it is covered the literature from 2009 to 2020 on the applications of GC×GC involving the pyrolysis of Brazilian agribusiness residues, such as cane straw, sawdust, coconut fiber, fruit seeds, rice husks, spent coffee grounds, among others.
Footprint of Arsenic Contamination in Sediments and Water from Mining Sites – A case study based on multivariate optimization by GF AAS
Glenda Máris Mesquita de Filippis, Bruno Elias dos Santos Costa, Simone Soares de Oliveira Borges, Waldomiro Borges Neto, Nivia Maria Melo Coelho, Luciana Melo Coelho
This paper presents a procedure to evaluate the occurrence of arsenic in environmental sediment and water samples by GF AAS, combining the efficiency of permanent modifiers with an appropriate temperature program, obtained from multivariate optimization.
Carcinogenic and Non-carcinogenic Health Risk Assessment of Heavy Metals in Njaba River, Imo State, Nigeria
Victor Chukwuemeka Eze, Chidiebere Temple Ndife, Miracle Oluebube Muogbo
In this research, the potential health risks due to exposure to potentially toxic elements were estimated in children and adults. The evaluation of the carcinogenic and non-carcinogenic health risks of the analyzed elements was carried out based on the guidelines of the USEPA.
Hair mineralogram analysis for health assessment: Statistical bias from gender and aesthetic treatments
Gabrielly Peregrino, Carlos G. Massone, Adriana H. Nudi, Tatiana Dillenburg Saint’Pierre
This research aimed to identify standard patterns among mineralogram results and some variables, such as gender and the use of aesthetical treatments that can point out differences and causes of variation in elemental concentrations in hair.
