	abstract = {The arsenic species present in samples of the crayfish Procambarus clarkii caught in the area affected by the toxic mine-tailing spill at Aznalcollar (Seville, Southern Spain) were analyzed. The total arsenic contents ranged between 1.2 and 8.5 mug g(-1) dry mass (DM). With regard to the different species of arsenic, the highest concentrations were for inorganic arsenic (0.34-5.4 mug g(-1) DM), whereas arsenobetaine, unlike the situation found in marine fish products, was not the major arsenic species (0.16 +/- 0.09 mug g(-1) DM). Smaller concentrations were found of arsenosugars la (0.18 +/- 0.11 mug g(-1) DM), 1b (0.077 +/- 0.049 mug g(-1) DM), 1c (0.080 +/- 0.089 mug g(-1) DM), and 1d (0.14 +/- 0.13 mug g(-1) DM). The presence of two unknown arsenic species was revealed (U1: 0.058 +/- 0.058 mug g(-1) DM; U2: 0.12 +/- 0.12 mug g(-1) DM). No significant differences were seen with respect to the total arsenic contents between the sexes. However, significant differences in the total arsenic contents were revealed between the area affected by the spill and the area not affected, the contents being greater in the affected area.

	abstract = {The concentrations of total arsenic and arsenic species in the complete organism of the crayfish Procambarus clarkii and its various parts (hepatopancreas, tail, and remaining parts) were analyzed in order to discover the distribution of arsenic and its species. With this information it will be possible to establish where the chemical forms of this metalloid tend to accumulate and what risks may derive from the contents and species present in the edible parts of this crustacean. The total arsenic content in the complete organism and in the various parts analyzed ranged from 2.5 to 12 mug g(-1) dry mass (DM), with inorganic arsenic representing 18 to 34\% of total arsenic. The arsenical composition varied according to the part of the crayfish considered. The hepatopancreas had the highest levels of total arsenic (9.2-12 mug g(-1) DM) and inorganic arsenic (2.7-3.2 mug g(-1) DM). The tail (edible part) had the lowest levels of both total arsenic (2.5-2.6 mug g(-1) DM) and inorganic arsenic (0.46-0.64 mug g(-1) DM). The predominant organoarsenical species were the dimethylarsinoylribosides: glycerol riboside in the hepatopancreas, sulfate riboside in the tail, and sulfonate and phosphate ribosides in the remaining parts.

	abstract = {We studied chemical speciation of arsenic compounds in urine samples by using HPLC with inductively coupled plasma mass spectrometry detection. We examined urinary arsenic excretion patterns and the arsenic species excreted from nine human subjects who ingested seaweed products and crab (or shrimp). Fast urinary excretion of unchanged arsenobetaine was seen after ingestion of crab and shrimp, which contain arsenobetaine as the major arsenic species. In contrast, the arsenosugars, which comprise the major arsenic species in seaweed, are metabolized and have a longer retention time in the human body. When nine volunteers ingested the commercial seaweed product nori, both the urinary arsenic excretion pattern and the excreted arsenic species varied from individual to individual, and as many as six metabolites could be detected. It seems that arsenosugars are not decomposed by stomach acid and that reactions involving enzymatic and (or) microbial activity in the human body may be responsible for the metabolism of arsenosugars.},
