Spatial and Multivariate Analysis of Trace Elements in the Surface Water and Deep Sediments of Fresh Water Aquatic Ecosystem

Abstract

The aim of this study was to assess the levels of various trace metals present in water and sediment of fresh water aquatic ecosystem during the post monsoon season. The study was extended to identify the trace metal contamination in the water and sediment samples collected along the shores of Lambapur and Peddagattu the tribal villages in India using an Inductively Coupled Plasma Optical Emission Spectrometer (ICPMS). The trace metal contents in water samples were copper-24.2 to 47.5, chromium-4.4 to 8.2, cadmium-0.1 to 0.3, lead-2.1 to 3.8, Nickel-5.9 to 9.7, Zinc-4.6 to 9.7, Manganese-10.8 to 13.2, Iron-52.9 to 157.2 (µg L −1 ) cobalt and arsenic were in BDL and the values were within the limits of Indian drinking water standards (BIS 10500: 1991). The trace metals concentration in the sediment samples ranged from (mg kg −1 ): Copper-61.5 to 113.7, chromium-138.4 to 177.5, cobalt-33.2 to 42.7, cadmium-1.0 to 2.1, lead-57.9 to 103.4, Nickel-36.1 to 56.6, Zinc-51.2 to 102.1, Manganese-610.8 to 1301.7 and Iron-2.5 to 2.9%. In our study, four reliable indices such as Enrichment factor, Contamination factor, Geoaccumulation Index and Pollution Load Index were applied to estimate metal pollution and the results comparison are discussed below. The data generated were used to determine the quality of the sediments based on the enrichment factor, contamination factor and degree of contamination, geochemical index and Pollution Load Index (PLI).

Potential anticancer properties of bioactive compounds of Gymnema sylvestre and its biofunctionalized silver nanoparticles

“…In future, the elemental analysis can be carried out as described earlier by other researchers. 53,54 XRD analysis of NPs represented in Figure 6 shows several size-dependent features leading to irregular peak position, height, and width. XRD was mainly carried out to study the crystalline nature of the green-synthesized G. sylvestre SNPs.…”

Calidad De Sedimentos Asociada a Actividades Antrópicas en Lagunas Costeras Semiáridas Subtropicales De La Costa Central Este Del Golfo De California

“…En este estudio, el Fe se utilizó como un elemento de normalización debido a su enorme disponibilidad y a que los estudios previos señalan que posibles pequeñas variaciones en la concentración de Fe no afectarán al elemento traza a investigar (Helz 1976, Rule 1986). En primer lugar, se utilizaron los coeficientes de Pearson para comprobar las correlaciones entre el normalizador (Fe) y los elementos traza (Arunachalam et al 2014). Adicional a la normalización de los metales en las fracciones de grano fino (< 63 µm), se utilizó la media del Fe de El Soldado como elemento indicador para determinar el impacto de la influencia humana en las lagunas de estudio, a través de los trabajos de Förstner y Wittmann (1981) …”

“…Arunachalam et al (2014), reportan una correlación de Pearson negativa para los pares de Cd vs. Cu, Cr, Pb, Ni, Zn, Mn y Fe pero no explican a qué puede estar realcionada. En este trabajo la correlación negativa del Cd (p > 0.05) con los demás metales puede deberse a que el 99 % de Cd presente en aguas superficiales en la región del Golfo de California tiene un origen natural relacionado con procesos físicos de surgencias y advección de aguas, mientras que sólo el 1 % proviene de fuentes antrópi-cas (Sañudo-Wilhelmy y Flegal 1991).…”

Geochemical hunting of lithogenic and anthropogenic impacts on polymetallic distribution (Bregalnica river basin, Republic of Macedonia)

“…[12] Thus, the distribution of trace metals in sediment adjacent to populated areas (includes industries, mining exploitation in particular) can give us the evidence of anthropogenic influence on aquatic system and convenience in assessing the potential risks associated with human waste discharge. [13] For example, in the Republic of Macedonia there are several significant pollution sources of potentially toxic elements/metals that continuously introduce tailings and waste into river waters. [14] These hotspots are predominantly present in the southeast part of the country.…”
