metal contents viz., cu, ni, co, zn and cd in sediment cores recovered from the vembanad lake, the largest estuarine-lagoonal system on the west coast of india, were analysed to understand the pollution levels and the impact on the coastal environment. of the three cores studied, vc-10 shown enrichment in all metals compared to other cores, as it is located in the vicinity of industrial area. f...
Abstract The fractionation of 10 metals (As, Co, Cr, Cu, Mn, Ni, Pb, Se, V, and Zn) within labile fractions in shallow marine sediments collected from the coasts Sabah Sarawak, Malaysia, was evaluated. Spatial distribution revealed that coastal were approximately 10% higher metal content than Sarawak. Risk assessment code, enrichment factor, pollution accumulation index calculations used to inv...
an increase in heavy metal pollution in the soils of arak due to industrialization and urbanization has become an environmental problem. the region hosts several industrial facilities which are the main source for hazardous wastes which include electric, metal, automotive supply industry, food, machinery, and chemicals. soil samples were collected from these industrial areas in the central and ...
This study comprehensively investigated the distribution, source identification, and potential ecological risk of heavy metals (As, Ni, Pb, Cd, Cr, Cu, Zn) in surface sediments Mongla port area Bangladesh. The sediment samples were collected from ten sampling points during wet dry season analyzed by atomic absorption spectrophotometer. average concentration metal was higher (11.36 to 118.55 mg/...
Background and Objective: The establishment of pelletizing and steel industries in Ardakan suburbs has increased the pollutants such as heavy metals into the environment. The purpose of this study was to investigate the contamination of the area soil by heavy elements around these industries using the pollution index (PI), comprehensive pollution index (NIPI), accumulation index (Igeo) and enri...
Thirty five bottom sediment samples were collected in a grid pattern from Wadi Al-Arab Dam. The present study focuses on the levels of Mn, Fe, Cu, Zn, Cd, total organic matter (TOM) and carbonate content (CO(3)(-2)) in order to assess the extent of environmental pollution and to discuss the origin of these contaminants in sediments of the dam. Concentration data were processed using correlation...
Background: Intestinal type of gastric cancer (IGC) is the largest subtype (GC). The purpose was to construct a prognostic signature for IGC patients improve accuracy. Methods: microarray datasets and associated clinical characteristics HGD were obtained from Gene Expression Omnibus (GEO) database. Based on differential expression analysis between IGC, related genes (DEGs) identified in trai...
In current work, we examined the absorption of metal Copper in generally grown food crops (Maize & Millet), cultivated waste water irrigated different Districts Punjab, Pakistan. Analyzed samples Water, Soil, shoot and grain were processed through atomic spectrometric method. Our findings Shoot highest for Millet Sargodha, with wastewater (1.69 mg/kg 1.43 respectively). soil maximum Cu was ...
Measurements of Pb, Cu, Zn, As, Ni, Hg, and Fe heavy metals and major elements and components such as Ca, HCO3, SO4, Na, K, Mg and Cl in soluble rain fractions were performed on rainwater collected at Arak plain during the rainy seasons of 2012. Concentrations of the heavy metals in the soluble fractions decreased for Fe, Pb, Zn, Ni, Cu, As and Hg, respectively and the major elements and compon...
DNA samples derived from vertebrate skin, bodily cavities and body fluids contain both host and microbial DNA; the latter often present as a minor component. Consequently, DNA sequencing of a microbiome sample frequently yields reads originating from the microbe(s) of interest, but with a vast excess of host genome-derived reads. In this study, we used a methyl-CpG binding domain (MBD) to separ...
