Protected areas are significant due to the high value of natural resources they shelter. This study's primary objective is assess quality status water (13 lakes and Tisa River) localized in protected area River on territory Romania. A number 13 surface (Tisa situated through Natura 2000 ecological network studied. The chemistry potential pollution were analyzed by measuring analyzing a set twenty elements sixteen physico-chemical parameters. impact anthropogenic activities was settled applied analysis obtained results. human health risk noticed. Results indicated that waters rich Ni Fe probably interaction with groundwater Ni. Waters characterized contamination, which if directly or food chain consumed could negatively influence health. Piper Gibbs plots studied divided into three categories based water-rock interactions: mixed Ca2+-Na+-HCO3-, CaCO3-, Na+-HCO3-. Likewise, indices (Heavy metal Pollution Index, HPI Heavy Evaluation HEI) correlated As, amounts. findings this research imply influenced geogenic origin emergence activities. significance related understanding mechanisms quality, improving conserving resources, correspondingly any risks be identified.

Iron, manganese, and lead contamination in groundwater of Bangladesh: a review

Water Practice & Technology, Journal Year: 2024, Volume and Issue: 19(3), P. 745 - 760

Published: Feb. 12, 2024

Abstract Groundwater is a vital source of safe drinking water in Bangladesh and most South Asian countries. The study aimed to identify the sources assess contamination Fe, Mn, Pb groundwater. considered published articles, reports, data repositories concerned departments over past two decades using various search engines, including Web Science, Scopus, Science Direct, Google Scholar, etc. results showed concentrations groundwater exceeded 55.93, 75.44, 37.50%, respectively, different standards, World Health Organization United Nations Environmental Protection Agency. ranged from 0.003 16.6, 0.00063 3.11, 0.0006 5.01 mg/L, followed order Fe > Mn Bangladesh. Sources are mostly geogenic origin, while anthropogenic derives industry dust piles, vehicle exhaust discharge, lead pipes, faucets, fixtures, batteries. higher levels heavy metals cause health environmental hazards. recommended that make it unsuitable for purposes should be treated before consumption.

High pollution loads engineer oxygen dynamics, ecological niches, and pathogenicity shifts in freshwater environments

Journal of Hazardous Materials Advances, Journal Year: 2024, Volume and Issue: 14, P. 100425 - 100425

The current study comprehensively reviews the ecological niche and pathogenicity shift in freshwater microbial community response to stress induced by a high pollution load. provides unique understanding of how change oxygen level tends affect survival aquatic biota delving into an increase pollutant load affects stability. review indicated that loads alter balance resources such as organic matter, dissolved gases, light penetration, essential nutrients. This causes dynamics species-dependent microorganisms environments. also alteration genome microorganisms, leading development antibiotic resistance genes thereby increasing microorganisms. dynamic created lowers natural defence strategies environment, efficacy pathogens infest respective host. A detailed mechanisms involved exotoxins production interaction with will give important insight effect exotoxin. is importance both environmental medical interests. because not only detrimental organisms but resists improperly treated drinking water. Such water could retrogress wellness quality life when used continuously. An extensive on specific pollutants cause microbiota provide impact stability environment.

Factors affecting the performance of a pharmaceutical wastewater treatment plant: Characterization of effluent and environmental risk

Heliyon, Journal Year: 2024, Volume and Issue: 10(7), P. e29165 - e29165

Published: April 1, 2024

Pharmaceutical industries produce a huge volume of emerging pollutants (EPs) that pose threat to the aqueous environment. Biological processes have shown their inefficacy in treating many pharmaceutical products. The study assessed physicochemical parameters, EPs, heavy metals industrial wastewater, and removal efficiency (RE) an aerobic biological treatment plant. also contamination levels risk using several indices, such as Canadian Council Ministers Environment Water Quality Index (

Toxicity Evaluation, Source Apportionment and Associated Risk Assessment of Heavy Metals in Surface Water in Bangladesh's Dhaleshwari River

Published: Jan. 1, 2025

This study investigated the physicochemical parameters (pH, Temperature, DO, ORP, TDS and EC) of water quality along with 12 heavy metals concentrations in Dhaleshwari River. DO EC concentration indicated presence impurities higher salt content respectively. Various indices were applied to evaluate environmental human health risks. The average value Nemerow's pollution index (PN) was found be 41.2, river seriously polluted. Metal Index (MI) threshold warning for drinking purpose. Average HPI HEI 136.5 (HPI >100) 28.96 (HEI > 20), respectively, which is not suitable irrigation purposes. PLI 1.77 (PLI >1), revealed that moderately polluted aquatic life. According CCME (Canadian Council Ministers Environment) standard, mean ERI 1109.3, ecological risk Toxic metal sources located using source identification techniques such as principal component analysis (PCA), correlation (CA). total Heavy Toxicity Load (HMTL), 64.35%, 56.34%, 78.73%, 99.82%, 87.4% 86.87% As, Cd, Co, Cr, Mn, Pb should removed from surface ensure safety.
