“…The strong relationships between Cu, Zn, and Pb (Table 3 ) suggest quite similar pollution sources. Cu and Zn might originate from agricultural runoff and industrial and domestic wastewater as terrestrial sources (Njogu et al 2011 ; Sheela et al 2012 ; Zeng and Wu 2013 ; Villalobos-Castaneda et al 2016 ; Spagnoli and Andresini 2018 ), as well as quarrying activities (Etim and Adie 2012 ; Tiimub et al 2015 ). The highest CFs and EFs for Cu (3.0 and 4.4, respectively) and Zn (2.0 and 3.0, respectively) were found at station TS10 in the southwest of the lake (Figs.…”

“…4 and 5). Some authors explained that a higher level of As might originate either from excessive use of agrochemicals and fertilizers (Yisa et al 2011;Bai et al 2012;Cai et al 2015;Villalobos-Castaneda et al 2016;Javed et al 2018) or from atmospheric inputs such as the precipitation of aerosol particles released by quarrying activities (Tiimub et al 2015).

Forty-three surface sediment samples were collected in September 2019 from Tasaul Lake (Black Sea coast, Romania) to examine the metal distribution patterns, assess the level of metal contamination, and identify the pollutant sources. The determined mean metal concentrations were as follows: Al 49,772 mg/kg, Zn 84.40 mg/kg, Cr 83.70 mg/kg, V 76.45 mg/kg, Ni 42.53 mg/kg, Cu 34.27 mg/kg, Pb 26.30 mg/kg, As 12.49 mg/kg, and Hg 0.06 mg/kg. The metals in the surface sediments of Tasaul Lake displayed moderate spatial variation, with higher metal concentrations mainly occurring in the south and southeast (As, Pb, and Hg), southwest (Cu and Zn), and west of the lake (Cr, Ni, and V). Heavy metal contamination in sediments is assessed using pollution indices such as enrichment factor, contamination factor, and pollution load index. The highest CFs and EFs were determined for As (moderate to high pollution), followed by Pb (low to moderate pollution). The Cu, Zn, and Hg pollution indices showed values corresponding to low pollution levels, while Ni, Cr, and V presented the lowest indices, suggesting unpolluted sediments. Multivariate statistical analyses were performed to identify the origin of the analyzed heavy metals. Cr was predominantly sourced from lithogenic components, Ni and V originated from both natural and anthropogenic sources, and As, Cu, Zn, Pb, and Hg showed mainly anthropogenic sources such as agricultural runoff, domestic and industrial wastewater discharges, and quarrying activities.

“…The EF is a frequently used parameter for assessing the impact of anthropogenic activities in sediments by distinguishing between natural and human sources of a single element [89,90]. The CFs of Cr, Zn, and As show moderate contamination in the upper sections, which can be due to the natural weathering of the minerals (a known source of Zn) [80], the use of Pb-As insecticides and arsenic-based herbicides [34,[81][82][83] on agricultural land in neighboring areas, or atmospheric inputs (precipitation of aerosol particles released by quarrying activities) [84]. The most important sources of anthropogenic zinc in the soil also include coal and bottom fly ash, as well as the use of commercial products, such as fertilizers and wood preservatives, that contain zinc [85].…”

Chemical analysis was performed on sediment core samples collected from three salt lakes, Amara Lake, Caineni Lake, and Movila Miresii Lake, located in the northeast of the Romanian Plain. The concentration of 10 main elements, 6 heavy metals (HMs), 8 rare earth elements (REEs), and 10 trace elements (TEs)—determined using neutron activation analysis (NAA)—showed variability dependent on the depth sections, lake genesis and geochemical characteristics (oxbow, fluvial harbor/liman and loess saucer type). The assessment of pollution indices (contamination factor, pollution load index, geoaccumulation index, and enrichment factor) highlighted low and moderate degrees of contamination for most of the investigated elements. Principal component analysis (PCA) extracted three principal components, explaining 70.33% (Amara Lake), 79.92% (Caineni Lake), and 71.42% (Movila Miresii Lake) of the observed variability. The principal components extracted were assigned to pedological contribution (37.42%—Amara Lake, 55.88%—Caineni Lake, and 15.31%—Movila Miresii Lake), salts depositions (due to the lack of a constant supply of freshwater and through evaporation during dry periods), atmospheric deposition (19.19%—Amara Lake, 13.80%—Caineni Lake, and 10.80%—Movila Miresii Lake), leaching from soil surface/denudation, rock weathering, and mixed anthropogenic input (e.g., agricultural runoff, wastewater discharges) (13.72%—Amara Lake, 10.24%—Caineni Lake, and 45.31%—Movila Miresii Lake).

“…In one study [38], sediments collected in a section of the Lerma River (one of the largest in Mexico) were collected and analyzed by flame and GF-AAS and XRF to evaluate the concentration and seasonal distribution of Cr, Ni, Cu, Zn, Fe, Pb, and As. The differences were evaluated between the dry and rainy seasons and among sampling stations by statistical methods; contamination degree was assessed by calculating EF (using Fe as the conservative tracer) and geoaccumulation index.…”

<p>This review presents environmental geochemistry studies developed in Mexico involving analytical chemistry applied to marine, lake, lagoon, dam, and fluvial sediments, soils, and groundwater over the past 15 years. The paper summarizes the objectives of the research, the analytical methods that were used, the methodologies applied for the interpretation of the results, and the primary findings for the areas and specific substrates that were studied. Although diverse analytical techniques were applied, atomic absorption spectrometry was the primary method of analysis, followed by inductively coupled plasma atomic emission spectroscopy. Studies are widespread in the Mexican territory although some areas are still lacking in information; in addition, most of the country’s contamination problems have yet to be remediated.</p>
