Queirós, José P.; Machado, João F.; Pereira, Eduarda; Bustamante, Paco; Carvalho, Lina; Soares, Eugénio; Stevens, Darren W.; Xavier, José CarlosThe Antarctic toothfish Dissostichus mawsoni is a Southern Ocean long-lived top predator which is regularly captured on an annual fishery operating in the region. By its biological and ecological characteristics, it is a potential bioindicator for the concentrations of trace and rare earth elements in the Antarctic. As these elements are mainly transferred through the diet and a deficiency or excess of these el...
A Single Digestion Procedure for Determination of Major, Trace, and Rare Earth ...
Carvalho, Lina; Reis, Ana T.; Soares, Eugénio; Tavares, César; Monteiro, Rui J.R.; Figueira, Paula; Henriques, Bruno; Vale, Carlos; Pereira, EduardaThe simultaneous determination of major, trace, and rare earth elements in sediments requires the development of specific procedures to prevent interfer- ences. A single digestion method adapted from the EPA method 3051A is proposed for the quantification of 42 elements in sediments by inductively coupled plasma techniques associated with optical emission spectroscopy (ICP-OES) and mass spectrometry (ICP- MS). ...
