Such investigations are vital for the ongoing monitoring and preservation of water bodies and overall ecosystem health. In total, 44 composite sediment samples were collected from seven pristine environments and four mining sites. These samples underwent preparation, digestion, and analysis for heavy metal content, utilizing the inductively coupled plasma emission mass spectrometer (ICP-MS). Various tools and models, including the geo-accumulation index, enrichment factor, and degree of contamination, were employed to assess the impact of pollution on the environment. Modified ecological risk index were also used to evaluate potential ecological risks. The average concentrations of heavy metals in pristine sites spanned from 0.01±0.01 (Cd) to 73,753.64 ± 388.15 mgkg⁻¹ (Fe), while in mining sites, they ranged from 0.04±0.02 (Cd) to 56,394.25±400.66 mgkg⁻¹ (Fe). Comparing these concentrations against the USEPA Ecological Screening Values, Mean Shales levels, and the Canadian ISQG, it became evident that Pb, Cd, Zn, Ni, Co, and Mn concentrations generally remained below the recommended guideline values in both pristine and mining areas. However, concentrations of Cr, As, Cu, and Hg exceeded the prescribed threshold limits, particularly in the mining regions. Through Principal Component Analysis (PCA) and Geometrical Analysis for Interactive Aid (GAIA) modeling, two primary sources of heavy metals were identified: anthropogenic-related and geogenic-related. GAIA and PCA together explained 78.53 % and 79.40 % of the total variability in heavy metal concentrations, respectively. Overall, the pollution and ecological risk assessment indicated low to moderate contamination levels, with a notable exception of high arsenic contamination in the Nyam river. The findings of this study hold significance for assessing sediment conditions and river quality in mining communities within Ghana and globally.

Exposure to cadmium has been linked to a range of health issues, including kidney, liver, and lung failure.</p></div><div><h3>Methods</h3><p>Various samples from different sources are analyzed for their cobalt(II) content by extraction followed by UV–visible spectrophotometry and compared with atomic absorption spectrophotometry.</p></div><div><h3>Results</h3><p>The reagent 2-chlorobenzaldehyde thiocarbohydrazone forms yellow 1:2 [Cd(II)-2CBTCH] complex in ethylene chloridewhich was extracted from an acetate buffer (pH 5.8) and observed maximum absorbance at 420 nm. The molar absorptivity and Sandell's sensitivity of the complex was reported to be 0.7868 × 10⁴ L mol⁻¹ cm⁻¹ and 0.01428 µg cm⁻². The method obeys Beer's law in the range of 3.5–9.5 µg mL⁻¹ of [Cd(II)-2CBTCH] complex, which indicates linearity between two variables. For five replicate determinations (<em>n</em> = 5), the standard deviation was 0.84 with the regression equations as <em>y</em> = 0.0661 <em>x</em> + 0.01 with R² = 0.999 as the correlation coefficient. The relative standard deviation (% R.S.D.) was found to be 0.84.</p></div><div><h3>Conclusion</h3><p>The method was effectively used in variety of foods and water samples and was evaluated its performance in terms of Student ‘t’ test and Variance ‘f’ test, which indicates the significance of the present method as an inter comparison of the experimental values using atomic absorption spectrophotometer.</p></div>","PeriodicalId":73997,"journal":{"name":"Journal of trace elements and minerals","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2773050623000575/pdfft?md5=9ee13a381b81d63c981ec75ed68b6ad8&pid=1-s2.0-S2773050623000575-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138610637","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
