“…It is a cosmopolitan species, common in marine and littoral ecosystems (estuaries), saline, and freshwater. It is common in the Polish Baltic Sea: the Gdańsk Gulf (Pliński and Jóźwiak 2004 ), east coast of the Pomorska Gulf (Rosińska et al 2013 ), and Sopot (this study). It occurs particularly in highly morphologically transformed and eutrophic locations.…”

The biologically active compounds (fatty acids, pigments, phenolics, and flavonoid content) were studied in supercritical fluid extracts from the biomass of marine (Ulva clathrata, Cladophora glomerata, Polysiphonia fucoides, and their multi-species mixture) and freshwater (C. glomerata) macroalgae. Different extraction techniques were used in order to compare differences in the biologically active compound composition of the macroalgal extracts. The results indicated that the saturated and unsaturated fatty acids ranged from C9:0 to C22:0. The analysis of differences in the composition of unsaturated to saturated fatty acids in extracts showed that palmitic acid (C16:0) and oleic acid (C18:1, n-9) reached the highest value not only in marine monospecies and multi-species biomass but also in the freshwater macroalga C. glomerata. When comparing the similarity between the concentration of fatty acids and the ratio of the concentration of unsaturated fatty acids to saturated in macroalgal extracts, we found small but not statistically significant variations in values between years (up to 10%). This is acceptable for applications as a stable raw material for industrial purposes. Significantly higher values of fatty acids, carotenoids, and chlorophylls were obtained in the case of SC-CO2 extraction. The active ingredients of polyphenols, possessing antioxidant activity ranged from approximately 2–4%. Moreover, flavonoids represented less than 10% of the total content of polyphenolic compounds. The extraction efficiency of polyphenols was higher from a mixture of marine algae for the ultrasound-assisted extraction compared to freshwater. All these findings show that marine and freshwater macroalgae, as a raw material, have the optimal biologically active compounds composition for cosmetics.

“…Wśród związków występujących w niskich stężeniach wymienia się między innymi wielopierścieniowe węglowodory aromatyczne (WWA), pestycydy chloroorganiczne oraz polichlorowane bifenyle (PCB). Stanowią one poważny problem ekologiczny ze względu na ich dużą odporność chemiczną, słabą podatność na rozkład, wysoką toksyczność oraz dużą zdolność do bioaku-mulacji [3,4]. Wśród trwałych zanieczyszczeń organicznych istotną grupę stanowią polichlorowane bifenyle.…”

Streszczenie: W pracy przedstawiono porównanie różnych metod ekstrakcji polichlorowanych bifenyli (PCB) z osadów dennych. Zestawiono metodę ekstrakcji na gorąco, ekstrakcję ultradźwiękową, ekstrakcję poprzez wytrząsanie oraz modyfikacje tych metod. Dodatkowo ekstrahowanie próbek porównano stosując jako rozpuszczalniki n-heksan i mieszaninę n-heksan/dichlorometan. W próbkach oznaczono stężenie sześciu kongenerów dioksyn: PCB 28, PCB 52, PCB 101, PCB 138, PCB 153 i PCB 180. Analizę jakościową i ilościową wykonywano metodą chromatografii gazowej z detektorem wychwytu elektronów GC-ECD. Każda z badanych metod ekstrakcji okazała się skuteczna i selektywna dla poszczególnych PCB. Najlepsze rezultaty otrzymano ekstrahując próbkę ultradźwiękami, stosując mieszaninę rozpuszczalników n-heksan/dichlorometan.
