Soil Contamination by Heavy Metals and Radionuclides and Related Bioremediation Techniques: A Review

Soil Systems, Год журнала: 2024, Номер 8(2), С. 36 - 36

Опубликована: Март 22, 2024

The migration of heavy metals and radionuclides is interrelated, this study focusses on the interaction complex influence various toxicants. rehabilitation radioactively contaminated territories has a character based scientifically supported measures to restore industrial, economic, sociopsychological relations. We aim for achievement pre-emergency levels hygienic norms radioactive contamination output products. This, in its sum, allows further economic activity these without restrictions basis natural actions autoremediation. Biosorption technologies bacterial biomass remain promising direction remediation soils with that help immobilise consolidate contaminants. A comprehensive understanding biosorption capacity preparations selection more effective techniques elimination contaminants, as well overcoming differences between laboratory results industrial use. Observation monitoring make it possible evaluate process identify regions disturbed balance harmful substances. soil application phosphogypsum, by-product chemical industry, bioremediation processes considered.

Ecological and Health Risk Assessment of Heavy Metals in Groundwater within an Agricultural Ecosystem Using GIS and Multivariate Statistical Analysis (MSA): A Case Study of the Mnasra Region, Gharb Plain, Morocco

Water, Год журнала: 2024, Номер 16(17), С. 2417 - 2417

Опубликована: Авг. 27, 2024

Assessing groundwater quality is essential for ensuring the sustainability of agriculture and ecosystems. This study evaluates contamination by heavy metals (HMs) using GIS approaches, multivariate statistical analysis (MSA), pollution indices (heavy metal index (HPI), (MI), degree (Cd), ecological risk (ERI), (PI)), human health assessment (HHRA). The results revealed significant variations in concentrations across area, with highest found southern southeastern parts, characterized intense agricultural activities uncontrolled landfills. Statistical analyses indicated both natural anthropogenic sources contamination. Pollution showed medium to high water levels, HPI values ranging from 20.23 128.60, MI 3.34 12.17, Cd 2.90 11.73, indicating varying degrees ERI suggested a low all samples. However, assessments highlighted non-carcinogenic carcinogenic risks, particularly children, TCR some like Ni Cr exceeding safe limits, potential hazards. findings provide valuable framework policymakers develop targeted strategies mitigating sustainable management.

Geochemical Insights into Health Risks from Potentially Toxic Elements in Rural Aqueducts of Cocle, Panama: Unveiling Links to Local Geology

Water, Год журнала: 2025, Номер 17(1), С. 110 - 110

Опубликована: Янв. 3, 2025

The El Valle Volcanic Complex, located in the province of Cocle, Panama, presents geological characteristics that could be linked to public health problems. This study focuses on municipalities San Juan de Dios, Pajonal, and Caballero, where water is consumed directly from springs (groundwater outcrops). region has a high incidence non-traditional chronic kidney disease (nt-CKD) may associated with natural presence potentially toxic elements (PTEs) water. aimed analyze concentration PTEs groundwater assess carcinogenic (CR) non-carcinogenic (HQ) risk human direct ingestion Sediments, rocks, samples were collected. Major ions (As, Al, Ba, Co, Cu, Fe, Mn, Sr, Sb, Pb, V, Zn) measured, mineralogical composition rocks was analyzed. results showed Fe only PTE exceeded recommended for drinking water, according Panama regulations, Pb USEPA. In Caballero acceptable threshold CR HQ exceeded, higher percentage than Dios. contribute most are As. suggests region’s historical volcanic activity, involving release minerals rich these PTEs, along interaction between contributing phenomenon what led prolonged exposure elements, which correlates prevalence area. novel study, first conducted as it seeks uncover relationship geology site, consumption, implication risks, aim generating new information decision makers generation policies issues such nt-CKD cancer region.

Aquifers and Groundwater: Challenges and Opportunities in Water Resource Management in Colombia

Water, Год журнала: 2024, Номер 16(5), С. 685 - 685

Опубликована: Фев. 26, 2024

Water is essential for life on Earth, playing fundamental roles in climate regulation, ecosystem maintenance, and domestic, agricultural, industrial processes. A total of 70% the planet covered by water. However, only 2.5% fresh water, much it inaccessible. Groundwater main source planet’s available water resources. For that reason, groundwater a critically important resource, increasingly vulnerable due to crisis contamination. These challenges threaten availability clean safe necessitating an understanding effective sustainable management. This review presents overview concepts aquifers groundwater. Also, reflects importance these resources developing countries such as Colombia (South America). In addition, considers characteristics mineral waters, their uses, associated risks, well exploration control policies. country with immense biological wealth crucial maintaining global Nevertheless, managing Colombia’s challenge, many have not yet been fully explored. order achieve this, necessary study hydrogeochemistry through application advanced technologies analyze dynamics, distribution, quality groundwater, its vulnerability pollution change. On other hand, consumption can health benefits, positive cardiovascular gastrointestinal effects. But geogenic, biogenic, or anthropogenic elements heavy metals microplastics pose risk human health. The need proper management prevent risks environment emphasized. Therefore, integrated approach resource will ensure conservation use, secure continuous supply freshwater, facilitate adaptation
