“…Indeed, the concentrations of OCDD, 1.2.3.4.6.7.8-HpCDF and OCDF are also notably higher in the blank sample compared to the Table 1 Concentrations of dioxins (PCDDs) and furans (PCDFs) (pg/g dw) in Pseudovernia furfuracea lichen samples that were either unexposed (blank) or exposed to air at sampling stations St1-St6, and relative exposed to control (E/C) ratios Bull Environ Contam Toxicol other congeners. Bioaccumulation over long periods of time in soils and sediments does, in fact, affect the more highly chlorinated compounds to a greater extent than the less highly chlorinated compounds (Augusto et al 2007;Guidotti et al 2013), and this trend most likely occurs in lichens as well. More chlorinated PCDDs/Fs present a higher resistance to biological and chemical degradation, and a higher lipophilicity that causes a greater biomagnification (Vallejo et al 2015).…”

The ability of a transplanted lichen, Pseudovernia (P.) furfuracea, to act as a multi-tracer biomonitoring tool for As, Cd, Ni, Pb, 12 PAHs, 17 polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs) and 27 polychlorinated biphenyls (PCBs) was evaluated at six areas of varying risk (high, medium, negligible) of pollutant fallout from a municipal waste incinerator in central Italy. Transplanted P. furfuracea proved to be an useful tool to biomonitor PCDDs/Fs and PCBs. Concentrations of As, heavy metals, PAHs, PCDDs/Fs resulted similar for all monitored stations. Small differences in total PCBs (4378 and 4631 pg/g dw vs 3298, 4123, 3676 and 4022 pg/g dw) and dioxin-like PCBs (1235 and 1265 pg/g dw vs 794, 1069, 1106 and 1188 pg/g dw) were observed. Air concentrations of monitored compounds appear to be more related to general air pollution than point emissions from the incinerator.

“…All results were reported as g per 100 g of the cookies (g/100 g). Fat content was determined on a solvent extractor SER 148/3 (VELP Scientifica) based on the Randall technique (Guidotti et al, 2013). The water content in the cookies was evaluated by thermal drying, in accordance with BN-80/8133-03.…”

The present work was designed to evaluate the influence of incorporating freeze-dried black chokeberry powder on the chemical composition, antioxidant activity and sensory properties of cookies. Material and methods. The content of fat, water, total ash, protein and directly reducing sugars, total phenolic content (TPC), DPPH radical scavenging activity, and reducing power (FRAP) was determined in cookies containing a 5, 10 and 15% freeze-dried black chokeberry and control sample. Enriched cookies were prepared by replacing the dough with freeze-dried black chokeberry powder on a weight basis. The samples were subjected to Qualitative Descriptive Analysis and consumer hedonic test.Results. The incorporation a growing amount of black chokeberry resulted in an increase in the water, total ash and directly reducing sugar content and to a decrease in the fat content of the cookies. TPC increased from 14.1 mg GAE per 100 g control sample to 481.1 mg GAE per 100 g cookies with 15% black chokeberry. The multiple increment in DPPH radical scavenging activity and reducing power FRAP was observed in cookies with the additive in comparison to the control sample, which was due to the high antioxidant capacity of black chokeberry. The addition of black chokeberry influenced the sensory profile of cookies, resulting in their darkening, in turn strengthening the intensity of sour taste, chokeberry flavour and astringency and at the same time decreasing the intensity of sweet aroma, sweet taste and crumbliness of the cookies. The sample with 10% of black chokeberry showed a balanced sensory profile with high consumer liking. Conclusion. The consumer acceptance and high antioxidant activity of experimental cookies suggest that freeze-dried black chokeberry could be considered as a nutritive additive to cookies and other bakery products.Sady, S., Sielicka-Różyńska, M.

“…The matrices reported include fruits, water, vegetables, sediment and so on. [24][25][26][27] However, for animal tissue, this method has rarely been reported. [28][29][30] Multidimensional mass spectrometry will play a more important role in drug residue analysis in the future.…”

We developed a highly sensitive and specific method for determining DES residue in fish meat using gas chromatography coupled with tandem mass spectrometry (GC-MS-MS) with a triple quadrupole analyzer (QqQ). The samples were extracted using ethyl acetate, cleaned using florisil, and derivatized using a mixture of 99% N,O-bis(trimethylsilyl)trifluoroacetamide (BSTFA) and 1% trimethylchlorosilane (TMCS).The results showed that the GC-MS-MS system presented great advantages for the identification and quantitation of DES in fish meat. The limit of detection (LOD) and limit of quantification (LOQ) values were 0.0142 mg kg À1 and 0.0475 mg kg À1 , respectively. The recoveries from the spiked fish samples spiked at four levels were in the range of 86.1% to 106%. The precision of the method was evaluated using the relative standard deviation (RSD) and ranged from 1.39% to 9.62%. The linear range was from 1.00 to 100 mg L À1 with good linearity (r ¼ 0.9998). It can be concluded that the method is reliable for identifying and detecting DES residue at trace levels in aquatic products.
