“…Ramesh et al [151] determined REEs and heavy elements in surficial sediments of the Himalayan River system by TIMS to understand the behavior of REEs during weathering and transport in a secondary sedimentary environment. In addition, the decay systems of the radioactive REE isotopes 138 La, 147 Sm, and 176 Lu were used to establish the ages of a range of geological events, starting from the first steps of planetary formation to some of the younger events, like Deccan volcanism, and the TIMS technique was proved to be very valuable in such studies. Uranium isotope ( 234 U/ 238 U, 235 U/ 238 U) ratio data generated by TIMS was used to understand the occurrence and provenance of Kanyakumari Beach placer deposits of REEs in India [152].…”

“…SHRIMP dating methods have been extensively applied for the dating of a number of REE deposits the world over. REE deposits, such as carbonatite deposits, can be dated very precisely using the decay systems of the radioactive REE isotopes 138 La, 147 Sm, and 176 Lu not only for understanding the age of REE deposits but also a range of events, starting from the first steps of planetary formation to younger steps of geodynamic development [154]. Thus, the abundance of all REEs occurring in a large range of concentrations as well as precise isotope ratios must be analyzed in different geomaterials for such studies.…”

The use of analytical techniques is important and critical in all areas related to REE, such as basic fundamental research, exploration, mining, extraction, and metallurgical activities at different stages by different industries. At every stage of these activities, rock, ore, minerals, and other related materials have to be analyzed for their REE contents in terms of elemental, isotopic, and mineralogical concentrations using different analytical techniques. Spectacular developments have taken place in the area of analytical instrumentation during the last four decades, with some of them having shrunk in size and become handheld. Among laboratory-based techniques, F-AAS, GF-AAS, ICP-OES, and MP-AES have become very popular. Because of high sensitivity, fewer interference effects, and ease of use, ICP-MS techniques, such as quadrupole ICP-MS, ICP-MS/MS, ICP-TOF-MS, MH-ICP-MS, HR-ICP-MS, and MC-ICP-MS, with both solution nebulization as well as direct solid analysis using laser ablation sample introduction methods, have become more popular for REE analysis. For direct analysis of solids, INAA, XRF, and LIBS techniques, as well as LA-based ICP-MS techniques, are being extensively utilized. The LIBS technique in particular requires little to no sample preparation. TIMS, SIMS, and SHRIMP techniques are being used for isotopic as well as dating REE depots. Portable analytical techniques, such as pXRF, pLIBS, and Raman spectrometers are able to perform in situ analysis even in the field, helping to make fast decisions during exploration studies. At present, hyperspectral remote sensing techniques including handheld, drone, and satellite-based techniques have become very popular in REE exploration studies because of their ability to cover larger areas in a limited time and, thus, became very cost-effective. Deployment of microanalytical devices/sensors mounted in remotely operated vehicles (ROV) is being successfully utilized in detecting REE-rich deposits in the deep oceans. Providing updated in-depth information on all these important aspects with suitable examples, especially from the point of view of REE research studies is the focal point of this review article.

“…This review focuses on the use of different ICP-MS technologies, such as classical ICP-MS, ICP-MS/MS, ICP-TOF-MS, HR-ICP-MS, MH-ICP-MS, and MC-ICP-MS. Quality detection and determination of metals, isotopes, and metal species, as well as quality control of various pollutants in drinking water, groundwater, underground water, wastewater, domestic water, water supply, and various industries, constitute the main topics covered in this study. Sasan Rabieh et al, [99] reported the MH-ICP-MS analysis of the freshwater and saltwater environmental resources of Upolu Island, Samoa. The authors analyzed 69 elements ranging from Li (3) to U(92) measured in each sample by Mattauch-Herzog inductively coupled plasma mass spectrometry (MH-ICP-MS).…”

Emerging contaminants, including pharmaceutical drug molecules, personal care products, and microplastics, are frequently present in the environmental samples. These are derived from various sources of municipal wastewater discharges, domestic solid waste dumped on land, disposal from farmlands, and industrial discharges. These may cause innumerous hazardous effects, particularly endocrine disruption to all the organisms exposed to such contaminants. The treated sewage sludge is applied to the agricultural field without screening for emerging contaminants. As a result of the toxicity exposed to the organisms, antibiotic-resistant bacteria disseminated in the environment due to the occurrence of antibacterial drugs in the environmental samples. It is reported that more than 200 different kinds of pharmaceutical drugs were found in the river water, and the ciprofloxacin concentration was up to 6.5 mg/l. Global water scarcity has a major impact on agriculture, leading to the use of treated wastewater for farmland. The United States Environmental Protection Agency (EPA) recognizes pharmaceutical and personal care products (PPCPs) as carcinogens and endocrine disruptors. Many scientists have recently reported that these kinds of novel contaminants are toxic and can affect the environment and health. This paper critically analyzes emerging contaminants and their impact on the environment and health. Further, it presents viable solutions to manage and control them through various analytical techniques, artificial intelligence, and machine learning methods.

“…Anthropogenic activities often lead to changes in the equilibrium of aquatic systems. The effects range from increases in heavy metal concentrations, chemical waste, runoff from agriculture of pesticides and fertilizers, to proliferation of pathogenic bacteria from sewage, which are all detrimental to natural flora and fauna [6][7][8]. Natural disasters and climate change cause severe droughts and heavier rainfalls which result in soil depletion and uncontrolled waste discharges, increasing the severity of negative impacts on aquatic systems [9,10].…”

Analysis of microbe diversity in freshwater resources and nearshore seawater samples of Upolu Island was performed to investigate the distribution of harmful bacteria. For this, 124 samples were collected from 23 river systems, two volcanic lakes, and 45 locations inside and outside the barrier reef of Upolu Island, Samoa. Physicochemical parameters for general water quality, detection of coliform bacteria and 16S rRNA amplicon sequencing were performed on all samples. Fecal indicator bacteria (FIB) testing indicated a wide distribution of coliform bacteria in all sampled freshwater sites with evidence of fecal coliform in most locations. Importantly, evidence of coliform bacteria was found in most seawater samples inside and along the reef, apart from those samples taken ~20 km offshore. Illumina 16S rRNA amplicon sequencing of the V4 hypervariable region confirmed the presence of various types of harmful bacterial species, namely from the Enterobacteriaceae, Enterococcae, Streptococcaceae, and Vibrionacea families. By combining the sensitivity of FIB testing and next-generation sequencing, we were able to show the extent of potential contaminations in fresh and seawater samples and simultaneously identify the potential pathogenic bacterial genera present. The wide distribution of potential harmful bacteria from river runoff or direct sewage dumping has an impact on human health, leading to many skin and intestinal diseases, and is potentially detrimental to coral reef community health.
