“…Tissue samples were subjected to nitric‐perchloric acid digestion (3:1 ratio) in digester block (MA‐4025, Marconi, Brazil) under increasing temperature until reaching 200°C then maintained for about 6 hr, as described in Silva (2009), followed by quantification in a microwave‐induced plasma optical emission spectrometer, model 4200 (Agilent Technologies, Melbourne, Australia). The instrumentation is detailed in Kleemann et al (2020).…”

“…Water treatment residuals (WTR) and biosolids (BS) (i.e. treated sewage sludge) (Mohajerani & Karabatak, 2020) are the main solid wastes generated during water purification for human consumption and wastewater treatment, respectively (Kleemann et al, 2020; Mahdy et al, 2020). The recycling of WTR and BS in fragile cropped soils is particularly promising (Dassanayake et al, 2015; Mukherjee et al, 2014b; Zhao et al, 2018).…”

Application of water treatment residuals (WTR) and biosolids (BS) might ameliorate fragile soils. However, studies integrating impacts of waste preparation methods such as liming and grinding associated with co-application approaches for soil conditioning are lacking. The present study aimed to evaluate the feasibility of agricultural use of WTR as well as their co-application with BS to ameliorate a sandy soil through assessing impacts on selected soil quality indicators and on nutrient and potentially toxic element concentration in plant tissue in addition to the biomass yield of annual crops. The following treatments were evaluated: non-amended soil (control); drying plus grinding and liming WTR; WTR co-application with BS at 3:1 ratio; and a soil amendment commercially available in Brazil. All treatments were soil incorporated in the 0.0-0.2 m layer at 30 Mg ha À1 dose (dry mass). Selected soil physical, hydraulic, and chemical parameters were determined. Furthermore, nutrients and potentially toxic elements concentration in plant tissue as well as the agronomic performance of maize and ryegrass were measured. The co-application of WTR and BS increased the soil content of P, Zn, and Cu in the 0.0-0.1 m layer. The concentration of these nutrients also was greater in ryegrass tissue and promoted the biomass yield in 51%. WTR did not increase contaminants and did not decrease the P content in soil and in plant tissue, independently of drying plus grinding and liming. Considering the conditions investigated in our study, WTR/BS co-application was environmentally safe and effective in ameliorating soil quality.

Over the last decade, a revolutionary progress in both the instrumentation and the application of microwave plasma (MWP) systems for optical and mass spectrometry is observed. In this article, the current status of these systems is comprehensively reviewed and updated to 2022 to provide the reader with an advanced understanding of the theory, practices, and instrumentation associated with MWP‐based spectrometric techniques. Diverse MWP devices that can serve as atomizers, and radiation or ionization sources for various spectrometric techniques are all discussed and classified according to their fundamental microwave features and power coupling mode. Two basic MWP types constitute electrode‐operating capacitively coupled microwave plasmas (CMPs) and electrodeless microwave‐induced plasmas (MIPs). The recent development of the brand new devices such as microwave inductively coupled plasmas, rotating field MWPs, and microwave micro‐discharges is also discussed. In addition, so‐called tandem plasma sources that are a combination of MWP with another type of plasma are briefly commented on. An introduction to the various sampling techniques that can cope with MWPs such as hydride generation (HG), chemical vapor generation (CVG) and photochemical vapor generation (PCVG) for gaseous samples, solution nebulization for liquids, and dry aerosol generation techniques [electrothermal vaporization (ETV), spark (SA), laser ablation (LA), direct vaporization and ionization (DI), and continuous powder introduction (CPI)] for solids are presented highlighting their relative merits and demerits. Also, recent advances in sampling of nanoparticles for time‐resolved measurements and single particle analysis are mentioned. Further, a broad range of MWP‐based optical and mass spectrometric techniques is covered. Optical emission spectrometric (OES) methods based on MWPs are reviewed because a considerable amount of research is presently being performed in this field. Even when much less reported in the literature, several nonemission spectrometric techniques are also discussed. The mass spectrometry (MS) techniques including both the elemental mass spectrometry with hot MWPs and a variety of molecular MS techniques utilizing either hot or cold MWPs are discussed. Advances in sample introduction strategies, instrument optimization, calibration methods, and applications of MWP analytical spectrometry are discussed in the following sections. Due to the diversity of MWP instrumentation and related spectrometric techniques, it is impracticable to treat equally all of these issues in this survey. For this reason, the discussion of analytical performance and practical use is focused on key MWP‐based spectrometric techniques that have been employed, alone or hyphenated, using commercial instrumentation. The review of routine determination of metals and metalloids in different categories of samples is focused to cover the application of nitrogen MWP Optical Emission Spectrometer. Extended capabilities by hyphenating microwave plasma optical emission spectrometry (MWPOES) and microwave plasma mass spectrometry (MWPMS) to various well‐known separation techniques such as gas or liquid chromatography, and also size‐exclusion chromatography are discussed in brief. The application of advanced spectroscopic techniques in a wide range of environments focusing mainly, but not exclusively, on industrial and bioanalytical applications, its advantages, and limitations over other multielement instrumental techniques are discussed. Some of the areas where more developments can be expected in the future are suggested.
