This paper reports the first results on alkylphenol pollution in edible bivalves from the Spanish coast. Two sampling campaigns (July 2006 and July 2007) were carried out to determine the concentration of nonylphenol (NP), octylphenol (OP), and eight polycyclic aromatic hydrocarbons (PAHs) in wild mussels (Mytilus galloprovincialys) and clams (Donax trunculus) at 14 sampling sites along the eastern Mediterranean Spanish coast. The results show that NP is the predominant alkylphenol, being the port of Valencia the most polluted area (up to 147 ??g/kg wet weight in clams). Moving away from the ports the concentration of NP in bivalves decreased. OP concentration was below its detection limit in most of the studied areas and its maximum concentration (6 ??g/kg w/w) was measured in clams from the port of Sagunto. The presence of low levels of PAHs was observed in most of the studied areas. The total PAHs concentration (i.e., sum of the eight measured PAHs) achieved a maximum value of 10.09 ??g/kg w/w in the north coast of Valencia city. The distribution pattern of the individual PAHs showed that both pollution sources petrogenic and pyrolytic were present in the sampled areas. Fluoranthene was the most abundant PAH in mussels while benzo(b)fluoranthene in clams. The maximum concentration of 10 ??g/kg w/w for benzo(a)pyrene established by the European Commission was never reached, indeed sampled bivalves showed concentrations 10 times lower than this reference value. Thus, they can be considered safe for human consumption. Despite the low contamination levels, the results show an overall pollution of bivalves by alkylphenol and PAHs as well as an increment in the number of polluted areas from 2006 to 2007. Thus, periodical sampling campaigns should be carried out to monitor the long-term tendency of these toxic and persistent pollutants. 相似文献

Abstract: High rates of human-mediated mortality on animals are frequently reported inside protected areas, especially near their borders, so the overall effect of reserves on animal conservation is not usually known. To determine the effect of a traditional reserve (Doñana National Park, southwestern Spain) on the Eurasian badger ( Meles meles ), a medium sized carnivore, we studied mortality causes and rates, with the aid of radiotelemetry, in two populations inside the reserve, one closer to the border than the other. Human-related mortality ( poaching and road kills) was by far the most common cause of mortality (85% of deaths recorded). The average annual mortality rate due to poaching was high (0.48 ± 0.08) for the population close to the border of the park, whereas none of the radiomarked badgers in the core of the reserve died during the study period. A logistic model that included distance from the border of the park, sampling effort, and the local area (i.e., edge and core populations) indicated that the difference between both sites was due to the effect of distance from the border on survival probability. On a regional scale, badger density at the core of the park was 3.16 times higher than outside. Overall, the effect of the reserve was positive, but edge effects reduced reserve effectiveness by 36%. Edge effects in close proximity of the border were strong, reducing badger density even below the expected density outside the reserve. Edge effects should be considered carefully when reserves are implemented because they can greatly reduce reserve effectiveness and influence the viability of the populations inside. Enlargement of reserves and control of human activities that promote edge effects, both inside and outside the reserve, are the two management actions that can most effectively mitigate edge effects. 相似文献
