This study aimed at: (a) providing information on the occurrence and concentration ranges in urban stormwater for a wide array of pollutants (n = 77); (b) assessing whether despite the differences between various catchments (land use, climatic conditions, etc.), the trends in terms of contamination level are similar; and (c) analyzing the contribution of total atm. fallout (TAF) with respect to sources endogenous to this contamination. The studied contaminants include conventional stormwater contaminants (polycyclic aromatic hydrocarbons (PAHs), Zn, Cu, Pb, etc.), in addition to poorly or undocumented pollutants such as nonylphenol and octylphenol ethoxylates (NPnEO and OPnEO), bisphenol A (BPA), polybrominated di-Ph ethers (PBDEs), a wide variety of pesticides, and various metals of relevance (As, Ti, Sr, V). Sampling and anal. were performed using homogeneous methods on three urban catchments with different land use patterns located in three distinct French towns. For many of these pollutants, the results do not allow highlighting a significant difference in stormwater quality at the scale of the three urban catchments considered. Significant differences were, however, observed for several metals (As, Cr, Cu, Ni, Sr and Zn), PAHs, and PBDEs, though this assessment would need to be confirmed by further experiments The pollutant distributions between dissolved and particulate phases were found to be similar across the three exptl. sites, thus suggesting no site dependence. Lastly, the contributions of TAF to stormwater contamination for micropollutants were quite low. This finding held true not only for PAHs, as previously demonstrated in the literature, but also for a broader range of mols. such as BPA, NPnEO, OPnEO, and PBDEs, whose high local production is correlated with the leaching of urban surfaces, buildings, and vehicles. In the experiment, the researchers used many compounds, for example, Isothiazol-3(2H)-one (cas: 1003-07-2Quality Control of Isothiazol-3(2H)-one).
Isothiazol-3(2H)-one (cas: 1003-07-2) belongs to isothiazole derivatives. Isothiazoles and benzisothiazoles are usually liquids or low-melting-point solids; polar substituents increase the melting points because of the possibility of hydrogen bonding and other interactions in the crystalline state. Many compounds with an isothiazole scaffold demonstrated a wide range of biological profiles, including antiinflammatory, antithrombotic, and anticonvulsive agents.Quality Control of Isothiazol-3(2H)-one
