Bioaccumulation for heavy metal removal: a review

SN Applied Sciences, Journal Year: 2023, Volume and Issue: 5(5)

Published: April 2, 2023

Abstract This paper reviews plants and microorganisms removal of heavy metals from contaminated sites through bioaccumulation. Increased industrial activities have led to the uncontrolled release into environment, resulting in a global increase metal pollution. Heavy are also consumed surface glasses over prolonged period use. pollution is serious problem that can wide-ranging long-lasting impacts on human health environment. Therefore, effective remediation crucial protect ecological health. Traditional methods removal, such as chemical treatment physical be costly negative The utilization for bioremediation metal-polluted environments has proven removing accumulation and/or detoxification. method effective, economical, versatile, environmentally friendly. Bioaccumulation utilizes absorb remove sites. not only cost-effective but helps minimize environmental impact Additionally, bioaccumulation used combination with other techniques, phytostabilization phytodegradation, further improve efficiency removal. discusses use water soil biomagnification bioconcentration.

Heavy metals contamination in water, sediments and fish of freshwater ecosystems in Pakistan

Water Practice & Technology, Journal Year: 2022, Volume and Issue: 17(5), P. 1253 - 1272

Published: April 20, 2022

Abstract Freshwater ecosystems are being contaminated by heavy metal pollution. The primary source of contamination is wastewater discharged from urban, industrial, and agricultural facilities. water contains hazardous amounts metals mixed in the freshwater ecosystem, causing deleterious impacts on marine life humans. This review paper highlights ecosystem Pakistan with metals. Heavy metals' concentration sediments, water, fish were assessed food chain, their relationship sites sources was explored. It observed that present sediments bio-accumulate into organs. also found some parts freshwaters such as rivers Ravi, Chenab, Kabul, Indus highly contaminated, they imposed negative human health. River receiving a huge amount industrial sewage urban centers industries Central Punjab, compared to other Pakistan. health best among all due enormous volume flow less number units along it. Indus, Jhelum consumable for presence causes social, environmental, economic problems. Therefore, should be treated before discharge streams lessen harmful beings.

Impacts of metal mining on river systems: a global assessment

Science, Journal Year: 2023, Volume and Issue: 381(6664), P. 1345 - 1350

Published: Sept. 21, 2023

An estimated 23 million people live on floodplains affected by potentially dangerous concentrations of toxic waste derived from past and present metal mining activity. We analyzed the global dimensions this hazard, particularly in regard to lead, zinc, copper, arsenic, using a georeferenced database detailing all known sites intact failed tailings storage facilities. then used process-based empirically tested modeling produce assessment contamination river systems numbers human populations livestock exposed. Worldwide, mines affect 479,200 kilometers channels 164,000 square floodplains. The number exposed sourced long-term discharge into rivers is almost 50 times greater than directly dam failures.

Potential human health risks associated with ingestion of heavy metals through fish consumption in the Gulf of Guinea

Toxicology Reports, Journal Year: 2023, Volume and Issue: 10, P. 117 - 123

Heavy metal pollution of the marine environment has toxic implications for both aquatic biota and human health. We examined levels Zinc (Zn), Lead (Pb), Copper (Cu), Cadmium (Cd), Arsenic (As) Mercury (Hg) in muscles Sardinella maderensis, Dentex angolensis, Sphyraena sphyraena Penaeus notialis caught from coastal waters Ghana using inductively coupled plasma mass spectrometry method. recorded highest concentrations all metals (Cu:12.08 ± 1.46 µg/g, Zn: 19.20 2.27 As: 8.46 2.42 Cd: 0.03 0.01 µg/g) except Hg. was relatively high D. angolensis (0.14 µg/g). Apart As, were within globally permissible daily limits consumption by per meal. The estimated Target Hazard Quotient due to intake Hg through exceeded threshold value across age categories.

Bio-concentration of hazardous metals in migrant shorebirds in a key conservation reserve and adjoining areas on the west coast of India

Ecotoxicology and Environmental Safety, Journal Year: 2025, Volume and Issue: 289, P. 117690 - 117690

Published: Jan. 1, 2025

Heavy metal pollution is a growing environmental concern as it causes the degradation of wetlands by affecting organisms at different trophic levels. Shorebirds typically feed on benthic invertebrates including polychaete worms, crustaceans and molluscs. Thus, assessment bioconcentration heavy metals in shorebirds provides an insight into extent bioaccumulation these hazardous upper We studied variation (chromium, lead cadmium) faeces 12 species (belonging to foraging guilds Endangered Great Knot, Vulnerable Grey Plover, Broad billed Sandpiper Curlew Near Threatened Eurasian Oystercatcher, Ruddy Turnstone Dunlin) relation trends their abundance over period five years (2019-2023). The study spanned three habitats (mudflats, mangroves sand beaches) Kadalundi Vallikkunnu Community Reserve (KVCR) adjoining beaches, which are important wintering/ stop-over sites for migrant that provide abundant nutritional resources shorebirds. demonstrate there has been drastic increase concentration shorebird from 2019 2023. Further, findings indicate predating biofilm-grazing mangrove habitats, well small-bodied general exposed high levels metals.
