Plastics pollution is a global issue impacting every part of our environment. Tire road wear particle (TRWP) plastics pollution is thought to be one of the largest pollution sources in urban environments. These plastics are also of concern due to the presence of additive chems., incorporated during manufacture, that can be released into the surrounding environment. This study aimed to provide information on concentrations of a range of anthropogenic plastics related pollutants in the Australian environment through a scoping study of surface water in 5 key urban centers around Queensland, Australia. Samples were analyzed for a suite of 15 common tyre additive chems., TRWPs and 6 common high production polymers, and included the new transformation product of concern 6PPD-quinone which has recent reports of causing mass mortality events in certain aquatic species. The additives were ubiquitously detected (2.9-1440 ng/L) with 6PPD-quinone concentrations lower than in previous studies (<0.05-24 ng/L) and TRWPs detected at 18 of the 21 sites (<MDL to between 690 and 1990μg/L). Of the high production polymers, polyethylene and polypropylene were detected at the highest concentrations (16-1750 and <0.7-37μg/L resp.) with profiles highly variable between sites. A traffic related additive profile was determined at 7 sites, which all had nearby traffic related sources. Concentrations of additive chems. were significantly correlated with average daily traffic volumes (p = 0.006), although concentrations of TRWPs were not correlated. Generally, concentrations were in line with or lower than concentrations in other geog. regions, although it is noted samples were collected during the dry season and further sampling during the tropical wet season would be of interest. In the experiment, the researchers used many compounds, for example, 1,3-Dicyclohexylurea (cas: 2387-23-7Synthetic Route of C13H24N2O).
1,3-Dicyclohexylurea (cas: 2387-23-7) belongs to amides. Amides include many other important biological compounds, as well as many drugs like paracetamol, penicillin and LSD. Low-molecular-weight amides, such as dimethylformamide, are common solvents. The presence of the amide group –C(=O)N– is generally easily established, at least in small molecules. It can be distinguished from nitro and cyano groups in IR spectra. Amides exhibit a moderately intense νCO band near 1650 cm−1. By 1H NMR spectroscopy, CONHR signals occur at low fields. In X-ray crystallography, the C(=O)N center together with the three immediately adjacent atoms characteristically define a plane.Synthetic Route of C13H24N2O
