Mercury compounds in tuna samples have been speciated by Bushee et al. [27] and by Huang and Jiang [28] in dogfish muscle and wastewater. Methyl mercury, ethylmercury, and inorganic mercury may be differentiated with picogram detection limits (Fig. 10.4). 

The speciation of arsenic compounds, using IPC and ICP-MS as a detector, has received much attention [33-39]. Beauchemin et al. [33,34] used IPC for the analysis of arsenic species in dogfish muscle. The ion-pair reagent was 10 iM sodium dodecylsulfate in a 5% methanol, 2.5% glacial acetic acid mobile phase at pH 2.5 with a C18 column. The toxic inorganic species, As (III) and As (V), as well as the less toxic organoarsenic species, monomethylarsenic (MMA), dimethylarsenic (DMA), arsenobetaine (AB), and arsenocholine (AC), were separated. AB was the dominant species and constituted 84% of the total arsenic concentration with a detection limit of 300 pg (as As).

Ebden and coworkers used coupled chromatography-atomic spectroscopy for arsenic speciation. Beauchemin and collaborators identified and determined arsenic species in dogfish muscle. The arsenic species were identified using liquid chromatogra-phy-inductively coupled plasma-MS, TLC and electron impact-MS. Results indicate that arsenobetaine constitutes about 84% of the arsenic present in the sample analysed.
