Fast environmental impact assessment through ICP-MS: application to bivalves from a tropical estuary (Pina Bay, Recife, Brazil)

Cladocerans (Branchiopoda) of a tropical estuary in Brazil.

The study was conducted in the Capibaribe river estuary in Recife (Brazil) to assess the role played by cladocerans in a eutrophic environment. Samplings were carried out monthly at 4 fixed stations along the estuary from July 1987 to June 1988. Collections were made with a plankton net of 65 micrometers mesh size. Six cladocerans species were registered: Penilia avirostris, Diaphanosoma spinul...

Assessment of Physical-Chemical Characteristics of Water and Sediments from a Brazilian Tropical Estuary: Status and Environmental Implications

The environmental quality of the Jacuípe River's estuary (very important in northeastern Brazil) was assessed during 2007 and 2008. In water, concentrations (mg L⁻¹) of NO₂⁻ (<0.004 to 0.016), NO₃⁻ (0.01 to 0.33), soluble PO₄³⁻ (<0.02 to 0.22), dissolved oxygen (3.9 to 9.6), total contents (mg L⁻¹) of Cd (<0.001), Cu (<0.01), Pb (<0.01), and Zn (<0.1), pH (5.60 to 8.00), and electrical conducti...

Rapid Analysis of High-Matrix Environmental Samples Using the Agilent 7500cx ICP-MS Application

The new Agilent 7500cx with Octopole Reaction System (ORS) is capable of analyzing most typical environmental samples using only one mode of analysis: helium mode. For the first time, it is possible to analyze an entire environmental suite of elements, including Hg and the major elements such as Na, K, Ca, Mg, Al, and Fe, in less than 2.5 minutes per sample, under conditions that remove or redu...

Fast and Accurate Determination of Arsenobetaine (AsB) in Fish Tissues Using HPLC-ICP-MS Application

A high performance liquid chromatography-inductively coupled plasma mass spectrometry method was developed for the fast and accurate analysis of arsenobetaine in fish samples extracted by accelerated solvent extraction. The combined extraction and analysis approach was validated using certified reference materials for arsenobetaine in fish and during a European intercomparison exercise with a b...
