Investigation of Heavy Metals Pollution and Their Removal Methods: A Review

Geomicrobiology Journal, Journal Year: 2024, Volume and Issue: 41(3), P. 213 - 230

Published: Feb. 19, 2024

The progress of the industry and increase in production pollutants have caused environment to be exposed pollution. Among pollutants, heavy metals (HMs) cause irreparable hazards due their accumulation non-biodegradability. Contamination water soil with HMs causes them accumulate plants animals, finally, they enter food chain effects on human health. nature is toxic, so even trace amounts can problems. Many factors release metals, such as improper waste disposal, sewage, agricultural fertilizers, pesticides, automobiles, coal mines, thermal power plants. Therefore, most important method properly manage sources pollution then remove that In this study, removal methods been investigated. For purpose, contamination (river, fish, shrimp), street dust, surface soil, vegetables, vegetable oils were Also, some (phytoremediation, use nanoparticles polymers) adsorbent materials (such zeolites, clay minerals, activated carbons) are

Enhancing Phytoextraction Potential of Brassica napus for Contaminated Dredged Sediment Using Nitrogen Fertilizers and Organic Acids

Plants, Journal Year: 2024, Volume and Issue: 13(6), P. 818 - 818

Published: March 13, 2024

Dredged sediment contaminated with heavy metals can be remediated through phytoremediation. The main challenge in phytoremediation is the limited availability of for plant uptake, particularly multi-contaminated soil or sediment. This study aimed to assess effect nitrogen fertilizers (ammonium nitrate (AN), ammonium sulfate (AS), and urea (UR)), organic acids (oxalic (OA) malic (MA) acids), their combined addition on enhancing bioavailability efficiency metals. dredged from Begej Canal (Serbia) had high levels Cr, Cd, Cu, Pb was used pot experiments cultivate energy crop rapeseed (Brassica napus), which known its tolerance highest accumulation translocation were observed treatment AN at a dose 150 mg N/kg (AN150), shoot biomass also highest. application OA MA increased metal uptake but resulted lowest production. A combination N showed Cr Cu.

Spatial distribution of trace and rare earth elements of bottom sediments in Lake Ostrowite, Bory Tucholskie National Park, Poland

Land Degradation and Development, Journal Year: 2024, Volume and Issue: 35(10), P. 3407 - 3421

Published: April 23, 2024

Abstract Lake pollution has attracted concerns worldwide; especially the excessive accumulation of trace elements (TEs) and rare earth (REEs) in bottom sediments can pose a serious threat to ecosystem health. However, there is still knowledge gap on level sediment lakes isolated from direct impact sources, their spatial variability, also factors influencing this state. The aim study investigate variability TEs REEs concentrations, as well determine source determining distribution Ostrowite. Ostrowite largest deepest water body located Bory Tuholskie National Park (in northern Poland), which completely isolates lake sources. covered analyses 32 surface samples sediments. concentrations 24 14 were determined using inductively coupled plasma mass spectrometry (ICP‐QQQ‐MS). assessment enrichment employed geochemical background values (GBV) that provided basis for calculation relative indices. determination sources supply routes was based cluster analysis principal component analysis. obtained results point with REEs.

River sediments serve as both a source and reservoir for potential heavy metal pollutants, providing critical insights into the health of aquatic ecosystems. Heavy contamination in global river systems poses significant risks to human through food chain. This study investigates contents metals, including Fe, Mn, Cu, Ni, Zn, Cr, Pb, Cd, surface sediment samples collected from mid–upper reaches Yellow River, which flows provinces Qinghai, Gansu, Ningxia, Inner Mongolia, Shaanxi, Henan. We analyzed spatial distribution characteristics these metals assessed their pollution levels by identifying sources contamination. The findings reveal elevated concentrations Cr Cd with particularly severe observed certain urban areas. are primarily linked activities related production daily life. offers valuable guidance local control prevention strategies.
