“…Various analytical techniques have been used for determination of chromium including spectrophotometry [6,7], atomic absorption spectrometry (AAS) [6,7], inductively coupled plasma atomic emission spectrometry (ICP-AES) [7][8][9][10], high performance liquid chromatography [11], etc. Due to the levels of chromium species in the natural and waste water samples are generally at g L −1 and high matrix contents of the samples, a separation/preconcentration technique is necessary, prior to determination of chromium by an instrumental technique [12][13][14][15][16].…”

“…Another possibility of identification chromium species is to determine trivalent chromium as the difference between total chromium and Cr(VI) after selective extraction with NaOH (Soares et al, 2010). Also hexavalent chromium can be determined as the difference between total chromium and Cr(III) (Gil et al, 2005). The significant proportion of the cadmium body burden can be found in liver and kidneys where it is bound to metalothioneins (Munoz Olivas and Camara, 2001).…”

Chemical Speciation & Bioavailability

The toxicity, mobility, bioavailability and bioaccumulation of metals are dependent on the particular physico-chemical form in which the element occurs in the environment. Special attention has been paid to metals which are essential for the proper functioning of organisms if present in appropriate amounts but are toxic if in excess (i.e. Se, Cr), and also to non-essential elements (i.e. Hg, Pb, Cd, Sn and As). To assess the potential hazard to the health of marine organisms, qualitative and quantitative analyses of metal species accumulating along the food chain needs to be carried out. This paper reviews the available information on the speciation of trace elements in the food chain in marine ecosystems and the analytical tools used for acquiring reliable information in this field. Advantages and limitations of commonly used techniques indicate that all metal species in different samples need diverse extraction, separation and detection conditions. Although not recommending which procedure is the most suitable to determine a given compound, speciation analysis has the potential to be a powerful tool for the identification of trace element species in biological samples.

“…Because of its importance, chromium chemical speciation analysis has been widely studied, and several analytical techniques has been suggested to do it, such as atomic absorption spectrometry with electrothermal atomisation (Zhu et al 2005;Krishna et al 2005;El-Shahawi et al 2005;Blas et al 2007), inductively coupled plasma mass spectrometry (Chen et al 2007;Krishna et al 2005), inductively coupled plasma optical emission spectrometry (Menegario et al 2005;Parodi et al 2005;Sumida et al 2005;Gil et al 2005) and fluorescence spectrometry (Chen et al 2005). However, the adsorptive cathodic stripping voltammetry (AdCSV) is a technique as sensitivity as versatile and can be applied to different environmental matrix, and it is also adequate to chemical speciation analysis.…”

The chemical speciation analysis of chromium in one of the most important South American Estuary was performed for the first time. Samples were collected in Patos Lagoon Estuary (Brazil) and were analysed by adsorptive cathodic stripping voltammetry, with the following analytical figures of merit: limit of detection, 0.1 nmol L(-1); precision RSD = 3%, n = 7; linearity, from limit of quantitation up to 20 nmol L(-1); and accuracy of 99.8%, expressed as recovery. No labile chromium forms were identified in samples, beside industries and a city were near the study area. It is pointed out a reverse correlation between total and non-active chromium and salinity, which could be explained by biogeochemical processes.
