Abstract The Ghizer River Basin (GRB) is one of the sub-basins Indus hosting rich mineralization and agrogenic activities. GRB was sampled for 55 water samples investigated potentially harmful element (PHE) concentrations using inductively coupled plasma mass spectrometry. PHE in were used to calculate potential non-cancer risks such as chronic daily intake (CDI), hazard quotient (HQ), cancer risk (CR). highest average chromium (37.1 ± 17.1 μg/L), copper (27.4 12.5 arsenic (4.8 0.9 cobalt (9.2 3.3 nickel (62.7 27.6 μg/L) noted Ishkomen segment GRB.

Microbial-Based Heavy Metal Bioremediation: Toxicity and Eco-Friendly Approaches to Heavy Metal Decontamination

Applied Sciences, Journal Year: 2023, Volume and Issue: 13(14), P. 8439 - 8439

Published: July 21, 2023

There are several industrial processes in which heavy metals used, including but not limited to chrome plating and tanning. Amongst the most toxic human health arsenic, cadmium, chromium, lead, copper, nickel, mercury. The aforementioned possess ability cause contamination upon their release into environment. Humans aquatic terrestrial animals at risk from water soil. Heavy metal toxicity has potential result complications, such as renal hepatic impairment, dermatological afflictions, cognitive lethargy, potentially oncogenic manifestations. removal of wastewater soil can be accomplished using a variety conventional methods, membrane filtration, reverse osmosis, chemical reduction, adsorption. These methods have disadvantages, generating an abundance secondary pollutants, entail significantly higher costs comparison biological methods. Conversely, eco-friendly techniques based on microbes numerous advantages. This review provides comprehensive overview that remove ions, both metabolically dependent independent. Additionally, we also focused source these metals. study is expected particularly beneficial for development treatment systems water.

Risk assessment of heavy metals in the major surface water system of Nepal with potential remediation technologies

Environmental Challenges, Journal Year: 2024, Volume and Issue: 14, P. 100865 - 100865

Published: Jan. 1, 2024

This paper presents an analytical risk assessment of heavy metals (HMs) in twenty-three rivers and two typical lakes across five different provinces Nepal. The study examines their effects on humans varying age groups ecological systems using indexes such as Hazard Index (HI), Cancer (CI), hazard quotient (HQ). human health reveals that female children are the most vulnerable to metal risks, followed by male children, adults, adults. Notably, Co, Pb, Cd, As, Cr, Cu present substantially high non-carcinogenic risks for all adults with HI values ranging from 1 more than 100. However, this is confined only (both female) Mn Ni. HMs Ni, Pb have a very carcinogenic some (CI > 1.00E-3). Concerning risk, HQ found be significantly above permissible limit order Cu>Cd>Pb>Fe>Zn>Co>Ni>Mn. Furthermore, integration various treatment technologies would enhance effectiveness eliminating polluted river water, ensuring water becomes suitable irrigation other purposes. identified priority controlling factors potential remediation can provide valuable insights policymakers making informed decisions concerning safety system.

Review on the impact of heavy metals from industrial wastewater effluent and removal technologies

Heliyon, Journal Year: 2024, Volume and Issue: 10(23), P. e40370 - e40370

Published: Nov. 15, 2024

The incidence of water pollution in developing countries is high due to the lack regulatory policies and laws that protect bodies from anthropogenic activities industrial wastewater. Industrial wastewater contains significant amounts heavy metals are detrimental human health, aquatic organisms, ecosystem. focus this review was evaluate sources treatment methods wastewater, with an emphasis on technologies, advantages, disadvantages, innovation. It observed conventional (such as flotation, coagulation/flocculation, adsorption) had shown promising results but posed certain limitations, such generation volumes sludge, relatively low removal rates, inefficiency treating metal concentrations, sensitivity varying pH. Recent technologies like nanotechnology, photocatalysis, electrochemical coagulation have advantages over for removing metals, including higher improved energy efficiency, greater selectivity specific contaminants. However, costs associated these advanced remain a major drawback. Therefore, we recommend future developments technology reducing both waste generation.

Addressing Heavy Metal Pollution in Nigeria: Evaluating Policies, Assessing Impacts, and Enhancing Remediation Strategies

Journal of applied science and environmental management, Journal Year: 2024, Volume and Issue: 28(4), P. 1007 - 1051

Published: April 29, 2024

Heavy metal pollution is a significant environmental concern in Nigeria, posing risks to ecological integrity and public health. This study aims evaluate the existing policies regulations addressing heavy pollution, assess their effectiveness, propose recommendations for improvement. The analysis reveals that while Nigeria has established robust legislative framework, challenges implementation, enforcement, funding persist. impact of reducing influenced by resource constraints, limited capacity, need stronger collaboration between regulatory bodies industries. Community involvement education play crucial role managing emphasizing importance awareness, sustainable practices, local engagement. Remediation strategies, such as bioremediation phytoremediation, offer potential solutions. However, gaps knowledge research exist, calling long-term monitoring, assessments, comprehensive health risk assessments. To enhance effectiveness current policies, periodic reviews, increased funding, community-based monitoring programs are recommended. By these implementing proposed recommendations, can make strides towards mitigating achieving sustainability.
