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

RSC Advances, Journal Year: 2023, Volume and Issue: 13(26), P. 17595 - 17610

Published: Jan. 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.

Role of Arbuscular Mycorrhizal Fungi in Regulating Growth, Enhancing Productivity, and Potentially Influencing Ecosystems under Abiotic and Biotic Stresses

Plants, Journal Year: 2023, Volume and Issue: 12(17), P. 3102 - 3102

Published: Aug. 29, 2023

Arbuscular mycorrhizal fungi (AMF) form symbiotic relationships with the roots of nearly all land-dwelling plants, increasing growth and productivity, especially during abiotic stress. AMF improves plant development by improving nutrient acquisition, such as phosphorus, water, mineral uptake. tolerance resilience to stressors drought, salt, heavy metal toxicity. These benefits come from arbuscular interface, which lets fungal partners exchange nutrients, signalling molecules, protective chemical compounds. Plants' antioxidant defence systems, osmotic adjustment, hormone regulation are also affected infestation. responses promote performance, photosynthetic efficiency, biomass production in stress conditions. As a result its positive effects on soil structure, cycling, carbon sequestration, contributes maintenance resilient ecosystems. The AMFs ecological stability species- environment-specific.

Abstract Soil-related problems have grown up to be a major threat human society. Scientific evaluation is helpful understand the status of soil pollution and provide reference further work. In this situation, Liaoning Province, typical industrial agricultural province in Northeast China, was selected as case study region. It reviewed 200 studies published between 2010 2020 recorded related data heavy metal. used model method index evaluate The comprehensive assessment score level 0.8998. Dalian 0.9536, ranking first among 14 cities. Huludao Jinzhou were 0.7594 respectively, ranked last. Heavy metal accumulation different cities stemmed from sources, including weathering parent materials, wastes, sewage irrigation, mining activities. general, at low risk level, but it still needs pay attention health input into soil, especially cadmium (Cd). This provides Liaoning, while identifying policy recommendations for mitigation environmental management.
