Total and toxic (sum of As(III), As(V), monomethylarsenic (MMA), and dimethylarsenic (DMA)) As concentrations were assessed in 19 respectively 4 different fish and shellfish species from the North Sea. Following results were obtained: (i) for fish an average total As concentration of 12.8 microg/g ww and a P90 value of 30.6 microg/g ww; (ii) for shellfish an average total As concentration of 21.6 microg/g ww and a P90 value of 40.0 microg/g ww; (iii) for fish an average toxic As concentration of 0.132 microg/g ww and a P90 value of 0.232 microg/g ww; (iv) for shellfish an average toxic As concentration of 0.198 microg/g ww and a P90 value of 0.263 microg/g ww. For the Belgian consumer the average daily intake of total arsenic from fish, shellfish, fruit, and soft drinks (the main food carriers of As in Belgium) amounts to 285 microg/day with more than 95% coming from fish and shellfish, while for a high level consumer it amounts to 649 microg/day, more than twice the average value. Using the same daily consumption pattern for the selected food products as for total As, we find that the average daily intake of toxic As amounts to 5.8 microg/day, with a 50% contribution of fish and shellfish and the high level intake to 9.5 microg/day. When considering the FOA/WHO Expert Committee's recommendation for inorganic As intake of 2 microg/kg bw/day or 140 microg/day for a 70 kg person, the toxic dose in Belgium is thus an order of magnitude lower.

“…It is a tremendous challenge to develop sensitive and selective analytical methods that can quantitatively characterize trace levels of heavy metals in several types of samples (Rao, 2005). Table 1 summarizes the optical and the electrochemical methods applied for heavy metals determination (Karadjova et al, 2007;Draghici et al, 2010 Draghici et al, 2010) Atomic absorption spectrometry (AAS) and atomic emission spectrometry (AES) are the most widely used techniques for heavy metals quantitative analysis in environmental samples.…”

“…Most of the current approaches to As, Pb and Hg speciation analysis rely on complete (or partial) extraction of species, with or without previous de-fatting and clean up of crude extracts, followed by high performance liquid chromatographic (HPLC) or CE separation and element-selective detection (Karadjova et al, 2007). Widely used extractants are water, methanol (MeOH)-water and MeOH-chloroform.…”

“…The NIST SRM 1566b was used to check the accuracy and the results are shown in Table 5. It can be supposed that some As compounds present in marine invertebrate samples are not digested at relatively low temperatures (Karadjova et al, 2007;Entwisle and Hearn, 2006;Matusiewicz and Stanisz, 2007); however, the chemical forms present in the digest probably did not exert a significant effect in ICP OES measurements. Results presented in Tables 4 and 5 indicated losses by volatilization after focused-microwave acid digestion.…”
