Mercury in Different Feather Types from Great Cormorants (Phalacrocorax carbo L.) Inhabiting the Vistula Lagoon Ecosystem in Poland
Total mercury levels in different feather types (down, contour, tail and flight) in Great Cormorants (Phalacrocorax carbo L.) were determined using CV-AAS. Feathers from Great Cormorants inhabiting the Vistula Lagoon ecosystem have an average Hg level of 7.14 ± 3.99 (μg/g w.w.). Age-dependent concentrations of Hg were statistically significant (ANOVA Kruskal-Wallis, p < 0.0001). There were also...
متن کاملThird-stage larvae of Anisakis simplex (Rudolphi, 1809) in the Great Cormorant [Phalacrocorax carbo sinensins (Blumenbach, 1798)] from the Vistula Lagoon, Poland
Five out of 28 Great Cormorants collected in spring 2005 from the Vistula Lagoon were found to contain a total of 19 (16 in the stomach and 3 in the intestine) stage III larvae of Anisakis simplex. Spring is the season when nematode-infected herring from the western Baltic, Danish straits, and the North Sea arrive in the Vistula Lagoon and transmit the infection to cormorants feeding on them. T...
متن کاملIn-air hearing of the great cormorant (Phalacrocorax carbo)
Many aquatic birds use sounds extensively for in-air communication. Regardless of this, we know very little about their hearing abilities. The in-air audiogram of a male adult great cormorant (Phalacrocorax carbo) was determined using psychophysical methods (method of constants). Hearing thresholds were derived using pure tones of five different frequencies. The lowest threshold was at 2 kHz: 1...
متن کاملExamination of Toxic Metals (mercury) in Coot (Fulica atra) and Cormorant (Phalacrocorax carbo) Collected in Anzali and Gomishan Wetlands, Iran
Background: Present study was carried out in north of Iran to investigate the concentration of mercury (Hg) as one of the most toxic metals in tissues of two species of birds. Methods: In this study, 15 birds from coot (Fulica atra) and 18 birds from cormorant (Phalacrocorax carbo) were hunted in Anzali and Gomishan wetlands. Data-analyses carried out using SPSS software version 17 licenced...
متن کاملA modified method for the determination of organic mercury in biota [great cormorants (phalacrocorax carbo)] by advanced mercury analyzer
Background: Contagion of aquatic ecosystems to heavy metals especially mercury (Hg) has risen concerns about healthiness of marine organisms. Organic mercury compounds are highly toxic for animals, and its detection in various samples is frequently needed. In present study we have described a new method for measurement of organic mercury and total mercury concentration in great cormorants (ph...
