“…The elevated concentration of Pb in sediments (Area B), as well as the Pb/Al ratios, match the increased values in the digestive gland of specimens from the same area. This response to the environmental availability is consistent with findings of other cephalopod studies (Bustamante et al 1998, Koyama et al 2000, Raimundo et al 2004, Napoleão et al 2005. Our results do not allow for the evaluation of the preferential pathway of accumulation; however, given the sedentary habits of octopus, both water and food should be considered vehicles for Pb uptake.…”

“…Pb concentrations in the digestive gland of Octopus vulgaris captured in the 2 areas ranged within the intervals observed in previous studies (Raimundo et al 2004, Napoleão et al 2005. The elevated concentration of Pb in sediments (Area B), as well as the Pb/Al ratios, match the increased values in the digestive gland of specimens from the same area.…”

“…River flow regime and pyrite belt location were invoked as major factors influencing these differences. A similar geographic contrast was found for Zn, Pb, Cd and Hg concentrations in the digestive gland of Octopus vulgaris (Raimundo et al 2004, Napoleão et al 2005, Seixas et al 2005: enhanced levels of Pb, Hg, and Zn were found in individuals from the south coast and higher accumulation of Cd was found in specimens captured in NW stations.…”

“…Miramand & Bentley 1992, Nessim & Riad 2003, Seixas et al 2005, Bustamante et al 2008. Furthermore, accumulated Pb levels appear to depend on the availability of Pb in water and food (Bustamante et al 1998, Raimundo et al 2004, Napoleão et al 2005. However, to our knowledge no attempt has been made to clarify whether accumulated Pb values in the digestive gland reflect an anthropogenic versus natural origin.…”

The present study evaluates the effects of different cooking methods (grilling, frying and boiling) on selenium contents of six marine species commonly consumed in Portugal. Forty-two composite samples of sardine, horse mackerel, gilthead seabream, silver scabbardfish, hake and octopus were digested in a microwave system and analysed by electrothermal atomic absorption spectrometry. The described method is adequate for the analysis of selenium in marine species and meets the requirements of validation and quality control. Mean selenium contents in raw species ranged from 0.35 mg kg −1 to 1.24 mg kg −1 . Cooked samples presented mean selenium contents from 0.38 mg kg −1 to 1.85 mg kg −1 in grilled fish, from 1.22 mg kg −1 to 1.28 mg kg −1 in fried fish and from 0.84 mg kg −1 to 0.87 mg kg −1 in boiled fish. No statistically significant differences were determined for selenium levels in raw and cooked samples and in different marine species. Estimated selenium intake agrees well with recommendations and is far below the Upper Tolerable Nutrient Level. This is the first study concerning the evaluation of the effects of cooking methods on selenium contents of marine species consumed in Portugal.
