Organic Pollutants in the Environment

Thermodynamic investigations of ligand–protein interactions: Binding of the phenazinium dyes phenosafranin and safranin O with human serum albumin

“…Decrease of the melting temperature (DT) by 6.4 and 8.3 K, respectively, with PSF and SO, under saturating conditions indicated that the binding destabilizes the protein structure. The thermal denaturation of HSA was found to be partially reversible under the conditions of this study and is in agreement with the literature report [34].…”

Environmental Nuclear Magnetic Resonance Spectroscopy: An Overview and a Primer

“…NMR is also an important tool in related areas of research including chemical ecology, biofuels, and assessment of wastewater composition including detection of pollutants. [6][7][8]52,53 Its unparalleled ability to provide detailed structural information on a range of environmental samples makes it one of the most versatile analytical techniques in modern science. 6−8,53−55 Another important aspect of environmental chemistry where NMR has been influential is in the identification of pollutants and their respective degradation products.…”

“…6−8,53−55 Another important aspect of environmental chemistry where NMR has been influential is in the identification of pollutants and their respective degradation products. 8,52,56 In 1976, Taves et al used 19 F NMR to identify perfluorinated organic fluorine compounds in human plasma, 57 decades before they were rediscovered by MS. 58 The hyphenation of liquid chromatography (LC) with NMR has also enabled the identification of components of more complex pollutant mixtures. 56 Collectively, NMR played a critical role in uncovering the structures and transformations in carbon pools in air, soil, and water, as well playing a role in understanding the fate of anthropogenic chemicals.…”

“…The important need to also elucidate the structure of organic matter found in sediments, water, and atmospheric particles have also necessitated the use of a range of NMR techniques. − Collectively, these studies have been influential in improving the understanding of organic matter structure, its sources and subsequent reactivity in various facets within the environment. NMR is also an important tool in related areas of research including chemical ecology, biofuels, and assessment of wastewater composition including detection of pollutants. − ,, Its unparalleled ability to provide detailed structural information on a range of environmental samples makes it one of the most versatile analytical techniques in modern science. − ,− …”
