“…The researchers concluded that different patterns of wastewater composition associated with water treatment, stormwater, and seasonality were linked. 144 Biochemical measurement is a highly important tool for the determination of the health of a river. Chemometrics, when applied to rivers, provides a tool for the assessment of substantially complex environmental data.…”

Combining Chemometrics and Sensors: Toward New Applications in Monitoring and Environmental Analysis

For many years, an extensive array of chemometric methods have provided a platform upon which a quantitative description of environmental conditions can be obtained. Applying chemometric methods to environmental data allows us to identify and describe the interrelations between certain environmental drivers. They also provide an insight into the interrelationships between these drivers and afford us a greater understanding of the potential impact that these drivers can place upon the environment. However, an effective marriage of these two systems has not been performed. Therefore, it is the aim of this review to highlight the advantages of using chemometrics and sensors to identify hidden trends in environmental parameters, which allow the state of the environment to be effectively monitored. Despite the combination of chemometrics and sensors, to capture new developments and applications in the field of environmental sciences, these methods have not been extensively used. Importantly, although different parameters and monitoring procedures are required for different environments (e.g., air, water, soil), they are not distinct, separate entities. Contemporary developments in the use of chemometrics afford us the ability to predict changes in different aspects of the environment using instrumental methods. This review also provides an insight into the prevailing trends and the future of environmental sensing, highlighting that chemometrics can be used to enhance our ability to monitor the environment. This enhanced ability to monitor environmental conditions and to predict trends would be beneficial to government and research agencies in their ability to develop environmental policies and analysis procedures.

“…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.…”
