Toxic heavy metal ions contamination in water and their sustainable reduction by eco-friendly methods: isotherms, thermodynamics and kinetics study

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: March 31, 2024

Abstract Heavy metal ions can be introduced into the water through several point and non-point sources including leather industry, coal mining, agriculture activity domestic waste. Regrettably, these toxic heavy metals may pose a threat to both humans animals, particularly when they infiltrate soil. poisoning lead many health complications, such as liver renal dysfunction, dermatological difficulties, potentially even malignancies. To mitigate risk of ion exposure it is imperative extract them from places that have been polluted. Several conventional methods exchange, reverse osmosis, ultrafiltration, membrane filtration chemical precipitation used for removal ions. However, high operation costs generate secondary pollutants during treatment. Biosorption an alternative approach eliminating involves employing eco-friendly cost-effective biomass. This review focused on contamination in water, biosorption mathematical modeling explain behaviour adsorption. helpful researchers design wastewater treatment plants sustainable

Biotechnological strategies for remediation of arsenic-contaminated soils to improve soil health and sustainable agriculture

Soil & Environmental Health, Journal Year: 2024, Volume and Issue: 2(1), P. 100061 - 100061

Published: Jan. 23, 2024

Soil health is the foundation of sustainable agriculture, and its preservation paramount in global arsenic (As) contamination challenges. As a critical issue for environmental agricultural sustainability. Rapid urbanization industrial expansion release toxic heavy metal(loid)s, including As, into soil. Arsenic disrupts rhizosphere ecosystem, affecting plant health, microbial communities, overall soil functionality. Ensuring face imperative human well-being developing resilient, environment. This review signifies need comprehensive strategies to revitalize ecosystems, promoting resilience long-term ecological balance. Advanced biotechnological approaches, particularly bioremediation phytoremediation, remediation, mycoremediation, nano-remediation, other integrative strategies, are highlighted their effectiveness addressing health. Conventional physico-chemical techniques make unsuitable agriculture by disrupting microenvironment. Consequently, urgent remediation demands adoption eco-friendly such as bioremediation, rhizoremediation, enhance Development transgenic lines genetically modified organisms (GMOs) effective tools reducing burden. Sphingomonas desiccabilis Bacillus idriensis bacteria expressing arsM gene, well subtilis transformed with potential GMOs that show promising results reduce Transgenic rice, incorporating gene from Rhodopseudomonas palustris, demonstrated 10 times more volatile arsenicals reduced accumulation grain. Additionally, use As-hyperaccumulating species conventional methods, like chemical-assisted phytoextraction, decontaminating As-polluted Future research should explore contributions novel regions affected contamination.

Abstract Water is essential to life on Earth, yet heavy metal concentrations in it can have negative consequences people's health. This study was designed measure the levels of seven metals (Fe, Zn, Cu, Pb, Cr, Cd, and Ni) drinking groundwater Jigjiga City asses associated health risk. samples were collected from 3 boreholes 7 tap. The measured using Flame Atomic Absorption Spectroscopy (FAAS). Chronic daily intake (CDI), hazard quotient (HQ), index (HI), Incremental lifetime risk assessment (ILCR) employed assess findings showed that range 7.77 ± 0.7 29.13 7.22 mg/L for Fe; 0.06 0.01–2.72 0.29 Zn; 0.65 0.04–2.15 0.63 Cu; BDL–0.36; BDL–0.45 0.24 Pb; BDL–1.43 0.15 Cd; 0.01 0–0.05 0 Cr 0.03 0.01–0.01 Ni.

ABSTRACT Presence of heavy metals in surface is the mounting concern world due rapid industrialization and modernization society, water being utilized both as source sink for consumption wastewater discharge, respectively. The chemometric method were applied on river pre post monsoon seasons to determine potential development metal pollution index (HPI). cluster factor analysis thirteen monitored over eleven locations characterizing highly correlating potential, respectively metals. proliferation health risks was determined through GIS. Fe Mn found exceeding permissible limits drain samples pre-monsoon post-monsoon season, whereas other within throughout study period. suggested that classification pollutants assessment associated risk human could provide a valuable insight remediation measures minimize degradation public appropriate treatment technology minimizing contamination sources.

Viability of two adaptive fuzzy systems based on fuzzy c means and subtractive clustering methods for modeling Cadmium in groundwater resources

Heliyon, Journal Year: 2023, Volume and Issue: 9(8), P. e18415 - e18415

Published: July 18, 2023

The Adaptive Neuro-Fuzzy Inference System (ANFIS) combines the strengths of both Artificial Neural Networks (ANNs) and Fuzzy Logic (FL) into a single framework. By doing so, it allows for quicker learning adaptable interpretation capabilities, which are useful modeling complex patterns identifying nonlinear relationships. One significant challenge in assessing water quality is difficulty time-consuming nature determining various factors that impact it. Given this situation, predicting heavy metal levels groundwater resources, urban rural, essential. This paper investigates two methods, ANFIS-FCM ANFIS-SUB, to determine their effectiveness Cadmium (Cd) resources. ‏The parameters be considered are: dissolved solids (TDS), electroconductivity (EC), turbidity (TU), pH were assumed independent variables. A total 51 sampling location used with resource develop fuzzy models. For evaluating performance ANFIS-SUB models, three different criteria including correlation coefficient, root mean square error, sum error comparing model outputs actual outputs‏.‏ Based on obtained results from scatter plots predicted value by ANFIS- FCM determination coefficient (R2) data, test train sets equal 0.978, 0.982, 0.993 0.983, 0.999 0.998 respectively. result proved Cd predictions implemented was significantly close measured all experimental data R2 0.983. compared found provided slightly higher accuracy than model. Also, comparison between indicated have strong potential estimating metals high degree accuracy.
