Metal Contents and Pollution Indices Assessment of Surface Water, Soil, and Sediment from the Arieș River Basin Mining Area, Romania

Sustainability, Journal Year: 2022, Volume and Issue: 14(13), P. 8024 - 8024

Published: June 30, 2022

The current study was conducted to assess the level and spatial distribution of metal pollution in surface water, soil, sediment samples from Arieș River basin, located central Romania, an area impacted by various mining industrial operations. Several indices, distributions, cluster analyses, principal component heat maps were applied for evaluating contamination with Ni, Cu, Zn, Cd, Pb, Mn, As, Hg area. Based on results Heavy-Metal Pollution Index Evaluation surface-water samples, middle part near downstream gold mine impoundment, characterized high levels. concentration higher tailing increased levels Pb soil Na, K, Ca, Al samples. Ca (23.7–219 mg/L), Mg (2.55–18.30 K (0.64–14.70 (0.06–22.80 Mn (0.03–22.40 mg/L) had most remarkable variation among while contents fluctuated strongly sampling locations. varied 743 19.8 mg/kg, Fe 529 11.4 2316 11.8 967 2547 mg/kg 3106 8022 314 5982 1367 8308 412 1913 Potential Ecological Risk values sediments orders Cu > Ni Cr As Zn Cd respectively, highest found around impoundment.

Heavy metal pollution in Manzala Lake sediments, Egypt: sources, variability, and assessment

Environmental Monitoring and Assessment, Journal Year: 2022, Volume and Issue: 194(6)

Published: May 17, 2022

The environmental pollution of lake systems due to anthropogenic factors is growing concern worldwide. Manzala Lake the largest northern coastal-deltaic lakes Egypt and has socioeconomic impacts. In this study, concentrations origins seven heavy metals (HMs) organic content in sediments were explored during winter summer. concentration HMs quantified using inductively coupled plasma loss-on-ignition techniques. Pearson's correlation coefficient (PCC) principal component analysis (PCA) applied evaluate sources sediments. matter enriched season. average conformed following sequence: Fe (14.13) > Mn (0.8) Cu (0.11) Zn Ni (0.06) Pb (0.5) Cd (0.002) (mg/kg). Sediment quality protocols showed that Mn, Cd, Cu, pose a significant threat aquatic environment Lake. geoaccumulation index (Igeo) values indicated with most metals, excluding Ni. periodic mean Igeo level followed sequence Fe. greatest load noted season was principally induced by Cu. overall ecological risk moderate, being prominent HM. PCA combined PCC HM enrichments southern (Bahr Al-Baqar Drain [S1], Bashteer [S3], Legan [S5], Al-Ginka [S8]) extreme northeastern (El-Qapouti [S6]) parts mainly discharge from different drains (industrial, agricultural, municipal wastes) industrial region Port Said, respectively. lower (Al-Boghaz [S2], Al-Temsah [S4], Al-Hamra [S7], Al-Kowar [S9]) their isolation urban areas compared other localities. Extensive waste disposal responsible for Advanced treatment technologies monitoring water are required decrease accumulation metals.
