Summary: In industrial processes such as chrome plating and tanning, toxic heavy metals like arsenic, cadmium, chromium, lead, copper, nickel, and mercury are used and released into the environment. These heavy metals pose a risk to human health and the well-being of aquatic and terrestrial animals. Heavy metal toxicity can cause various health complications, and their removal from wastewater and soil can be achieved through conventional methods like membrane filtration, reverse osmosis, chemical reduction, and adsorption. However, these methods have limitations and higher costs compared to eco-friendly approaches based on microbes. This review focuses on biological processes for heavy metal removal and also discusses the source and toxicity of these metals, aiming to provide valuable information for the development of biological treatment systems.

Summary: Heavy metal pollution is a serious threat to the environment and human health, and microbial mineralization technology has been widely studied for its remediation. This paper reviews the mechanisms and application examples of microbial-induced carbonate precipitation (MICP), microbial-induced phosphate precipitation (MIPP), and microbial-induced sulfide precipitation (MISP) in heavy metal remediation. It was found that MICP is more studied, while MIPP products are more stable in the natural environment and MISP is more suitable for anaerobic environments. The biomineralization effects and mechanisms of environmentally-friendly algae and heavy metal-tolerant fungi should be further studied.

Summary: Petroleum hydrocarbons and heavy metals are widespread contaminants in marine ecosystems, and microbial-based bioremediation shows promise as an effective and sustainable solution. In this study, we enriched the microbiome of heavily polluted sediments and isolated two novel bacterial strains that exhibited high degradation of PAHs and removal of HMs, with the best results observed for naphthalene, pyrene, and lead. The genetic repertoire of these strains may be further utilized for bioremediation of marine environments contaminated with PAHs and HMs.

Summary: A new method using LC-MS/MS for quantifying phenoxy herbicides in water samples was presented. The method utilized an automated SPE process with hydrophilic modified polystyrene and divinylbenzene cartridges at low pH, reducing organic solvent consumption and providing fully automated sample pre-concentration. Stable isotopically labelled analogues were used as internal standards to ensure accurate measurement. Analysis of thirty-two actual water samples showed a 40% detection rate of herbicides with concentrations comparable to other regions.

Unlike Advanced Oxidation Technologies/Processes (AOTs/AOPs), ARTs utilize a variety of reducing agents for electron donation. However, the conditions and requirements for ARTs, as well as the mechanistic details of reductive degradation/transformation of highly toxic compounds, are still not well-defined.

Summary: In this study, a dual-probe method combining hydrophilic 1O2 probe furfuryl alcohol (FFA) and its structural analogue furfuryl amine (FFAm) was used to quantify [1O2] in DOM samples. Results showed that the reactivity of FFAm was significantly higher than FFA at pH 7 and 8. The surface [1O2] of Suwannee River humic acid (SRHA) was determined to be 60 pM, which is 96-fold higher than the aqueous-phase [1O2] measured with FFA. This work expands the understanding of DOM microheterogeneous photochemistry and offers insights into the spatial distribution of 1O2 and other photochemically produced reactive intermediates.

Summary: The protonation state of dissolved organic matter (DOM) affects its structure and function, including light absorption and formation of reactive intermediates. Spectral pH titrations were performed on DOM isolates, whole water samples, and model compounds, revealing similar spectral features between them. Aquatic DOM isolates and soil-derived humic acid isolates exhibit different pH dependence, suggesting pH impacts DOM dynamics differently.

Summary: This paper investigates the activation mechanisms of peroxymonosulfate (PMS) in a catalyst-free system and its interaction with background oxyanions. The study shows that both phosphate and carbonate can activate PMS to produce sulfate radical. Phosphate has a stronger effect. The reaction between sulfate radical and ATZ produces other possible radicals, but their contributions to ATZ degradation are minimal.
