“…Some procedures involving cloud point extraction are summarised in Table 1, procedures involving co-precipitation in Table 2, and procedures involving sorbent systems in Table 3 Electrothermal AAS with Zeeman effect background correction has been used with solid sampling in the measurement of Cd, Hg, Mn and Pb in aquatic plants 195 and with slurry sampling in the measurement of Pb and Sn in sediments 196 . A method for direct Hg speciation in solid samples, involving controlled thermal release of analytes followed by quantification by AAS, has been proposed by Shuvaeva et al 197 .…”

This is the twenty-fifth annual review published in JAAS of the application of atomic spectrometry to the chemical analysis of environmental samples. This Update refers to papers published approximately between September 2008 and August 2009. In the analysis of air, work is focused on the need to collect and characterise ultrafines; determination of elements such as Be, Hg and PGEs in air samples; application of SRXRF techniques and advances in the development of field deployable aerosol mass spectrometry systems. In the analysis of water, significant areas of activity currently focus on elemental speciation of As, Cr, Hg and Sn. Work in increasing method sensitivities through the use of vapour generation and optimization of extraction and preconcentration procedures continues. The increased global awareness of the need to monitor levels of potentially toxic elements (PTE) in soils is desirable and this is reflected in a growing body of published literature from authors in the Middle East, Asia and Africa. However, a potential criticism of some studies is that they simply report the concentrations of analytes in particular soils or plants, without providing sufficient information on analytical quality control and with little assessment of their environmental significance, e.g. those levels that are a threat to human health. In the field of geological analysis, considerable effort is being spent not only on the production, characterization and certification of new geological reference materials, but also on enhancing the certification of existing reference materials and the development of reference materials with assigned elemental isotopic ratios. Laser ablation continues to go from strength to strength in being adopted as a solid sampling tool in geochemical analysis.

For energy production activity the ground water of 2nd aquifer (AQ2) of block 2 of Thar coal field is drained out in a reservoir/Gorano dam. In present study the physico-chemical and toxic elemental levels in ground water samples of 2nd aquifer (AQ2) of Thar coalfield at the depth of 100–120 m was carried out. The further sampling of water was carried out from drain outlet (DW) and four sampling sites of reservoir (S1, S2, S3 and S4). The sediment samples of water reservoir were collected from four sites and analyzed for toxic elements. The large data set of water quality of AQ2, DW and four samples sites at different spots of reservoir, carried out during 2019 for 17 parameters in triplicate of each composite samples were further analyzed by multivariate statistical techniques involving cluster (CA) and principal component analysis (PCA). The all water samples were analyzed for physicochemical parameters including cations and anions. The resulted data of cations (sodium, potassium, calcium, magnesium, cadmium, lead, total arsenic and iron), anions (chloride, fluoride, nitrate, sulphate and bicarbonate) and physicochemical parameters were descript in terms of basic statistical parameters, PCA and CA. The chemical correlations among different parameters were observed by PCA, which were employed to categorize the water samples by CA. The positive correlation of fluoride (F−) and total arsenic with sodium and bicarbonate indicated that the GW (AQ2), DW and water samples of reservoir with high conductivity and salinity stabilized the toxic elements in the water samples of different origin. Results showed that all collected water samples have high values of sodium absorption ratio. The water quality assessment indicated that the high levels of physicochemical parameters and toxic elements in ground and reservoir water have concern in and make it unsuitable for drinking and domestic purposes.

“…A variety of techniques including flame atomic absorption spectrometry (Detcheva and Grobecker, 2008), electrothermal atomic absorption spectrometry (Kiptoo et al, 2008), inductively coupled plasma optical emission spectrometry (Zhu and Alexandratos, 2007), inductively coupled plasma mass spectroscopy (Huang and Hu, 2008) and stripping voltammetry (Zejli et al, 2007) have been extensively used for the determination of heavy metals in different environmental and biological samples. Direct determination of trace amounts of metal ions in samples by FAAS is difficult because of low sensitivity especially of FAAS.…”

In the present study, silver (Ag), cadmium (Cd), nickel (Ni), cobalt (Co) and lead (Pb) were simultaneously determined in water samples of fresh water canal receiving untreated effluents from an industrial area, of Sindh Pakistan. The analytes in the water sample were determined by CPE using ammonium pyrrolidinedithiocarbamate (APDC) as a complexing agent and then entrapped in non-ionic surfactant, octylphenoxypolyethoxyethanol (Triton X-114). The surfactant rich phase was diluted with acidic ethanol prior to analysis by flame atomic absorption spectrometry. The variables affecting the complexation and extraction steps such as pH of sample solution, concentration of oxine and Triton X-114, equilibration temperature and time period for shaking were investigated in detail. The validation of the procedure was carried out by analysis of a certified reference sample of water (CRM1634e). Reliability of the proposed method was also checked by the standard addition method in a real sample at three concentration levels of all metals. Under the optimum conditions, the preconcentration of 10 mL sample solutions, allowed preconcentration
