Today I want to share an article with you. The article is 《Occurrence and tissue distribution of alkylphenols (APs) in selected waterbirds from the Southern Baltic》,you can find this article in 《Chemosphere》. The following contents are mentioned:
The aim of the present study was to determine the concentrations of nonylphenols (NPs) and 4-t-octylphenol (4tOP) in the muscles, liver, and kidneys of selected waterbird species. Three species with different feeding habits were selected, i.e., greater scaup (Aythya marila), great crested grebe (Podiceps cristatus), and great cormorant (Phalacrocorax carbo) to investigate the potential effects of diet on the level of contaminants tested. The determination and quantification of analytes were performed using gas chromatog. with mass spectrometric detection (GC-MS). The highest NP concentrations were noted in the kidneys of greater scaups and great crested grebes (208.3 and 160.8 μg kg-1 ww, resp.), which were six to fourteen-fold higher than those in the muscles (15.0 and 25.6 μg kg-1 ww, resp.) and livers (22.9 and 13.8 μg kg-1 ww, resp.) of these species. In greater scaups, the mean concentration of NPs in the livers was lower than in the muscles, while in great crested grebes, it was the opposite and higher concentrations were noted in the muscles. The mean concentrations of NPs in the muscles and livers of great cormorants were at similarly low levels (12.5 and 9.7 μg kg-1 ww, resp.). The concentrations of 4tOP in all samples were low, ranging from <LOQ to 0.29 μg kg-1 ww. The results of our study indicated that sex and diet did not affect the NP tissue concentrations in different waterbird species, but the phenol. period (migration vs breeding) might influence the contamination levels in the kidneys. The experimental procedure involved many compounds, such as 4-tert-Octylphenol (cas: 140-66-9) .
4-tert-Octylphenol(cas: 140-66-9) has been used as a reference standard for the determination of the analyte in water samples using ultra-high-performance liquid chromatography/tandem mass spectrometry (UHPLC/MS/MS).Name: 4-tert-Octylphenol
