Heavy metal pollution in the aquatic environment: efficient and low-cost removal approaches to eliminate their toxicity: a review

RSC Advances, Год журнала: 2023, Номер 13(26), С. 17595 - 17610

Опубликована: Янв. 1, 2023

Heavy metal contamination of water sources has emerged as a major global environmental concern, threatening both aquatic ecosystems and human health. pollution in the environment is on rise due to industrialization, climate change, urbanization. Sources include mining waste, landfill leachates, municipal industrial wastewater, urban runoff, natural phenomena such volcanic eruptions, weathering, rock abrasion. ions are toxic, potentially carcinogenic, can bioaccumulate biological systems. metals cause harm various organs, including neurological system, liver, lungs, kidneys, stomach, skin, reproductive systems, even at low exposure levels. Efforts find efficient methods remove heavy from wastewater have increased recent years. Although some approaches effectively contaminants, their high preparation usage costs may limit practical applications. Many review articles been published toxicity treatment for removing wastewater. This focuses main pollution, chemical transformation, toxicological impacts environment, harmful effects ecosystem. It also examines advances cost-effective techniques physicochemical adsorption using biochar zeolite ion exchangers, well decomposition complexes through advanced oxidation processes (AOPs). Finally, advantages, applications, future potential these discussed, along with any challenges limitations that must be considered.

The Utilization of Algae and Seaweed Biomass for Bioremediation of Heavy Metal-Contaminated Wastewater

Molecules, Год журнала: 2022, Номер 27(4), С. 1275 - 1275

Опубликована: Фев. 14, 2022

The presence of heavy metals in water bodies is linked to the increasing number industries and populations. This has serious consequences for quality human health environment. In accordance with this issue, wastewater treatment technologies including ion exchange, chemical extraction, hydrolysis should be conducted as a first purification stage. However, sequestration these toxic substances tends expensive, especially large scale methods that require tedious control have limited efficiency. Therefore, adsorption using adsorbents derived from biomass represent promising alternative due their great efficiency abundance. Algal seaweed appeared sustainable solution environmentally friendly adsorbent production. review further discusses recent developments use algal potential sorbent metal bioremediation. addition, relevant aspects like toxicity, mechanism, parameters affecting completion process are also highlighted. Overall, critical conclusion drawn algae can used sustainably eliminate wastewater.
