We investigated concentration of 18 pharmaceutical and personal care products (PPCPs) in the upper reaches of the Yamato river system using LC-MS/MS in winter and summer in 2020. This river system extends over the Yamato plain area which accounts for nearly 90% of the population in Nara prefecture, and the river flow rate is extremely lower than others in Japan. Therefore, high concentration of PPCPs from the residential and com. sector are expected to be detected. As a result, 17 PPCPs were detected in one of the rivers. The results were compared with those of a previous study in a large urban area, and showed that differences in drug use due to the aging of the population and differences in sewerage coverage may affect differences in the frequency of PPCPs detection in rivers. Furthermore, by comparing the concentration ratios of PPCPs, it was possible to identify points where the concentration ratios of PPCPs were different from those of other water sampling points, reconfirming the importance of regional surveys. We compared PPCPs concentration with predicted no-effect concentration (PNEC) to assess the ecol. impact. As a result, clarithromycin, erythromycin, diclofenac, and carbamazepine which were detected in excess of the PNEC. The concentrations of these substances were similar to or lower than those in previous studies. This study involved multiple reactions and reactants, such as 2-(4-(1-Hydroxy-4-(4-(hydroxydiphenylmethyl)piperidin-1-yl)butyl)phenyl)-2-methylpropanoic acid (cas: 83799-24-0SDS of cas: 83799-24-0).
2-(4-(1-Hydroxy-4-(4-(hydroxydiphenylmethyl)piperidin-1-yl)butyl)phenyl)-2-methylpropanoic acid (cas: 83799-24-0) belongs to piperidine derivatives. The piperidine ring can be found not only in more than half of the currently known structures of alkaloids, but also in many natural or synthetic compounds with interesting biological activities. Piperidine prefers a chair conformation, similar to cyclohexane. Unlike cyclohexane, piperidine has two distinguishable chair conformations: one with the N鈥揌 bond in an axial position, and the other in an equatorial position.SDS of cas: 83799-24-0
