“…Hg(II) pollution-which can cause significant neurodevelopmental risk to fetuses, newborns, and children- has long been considered a threat to public health and the environment 1 . The release of Hg(II) into surface water occurs mainly through discharge from industrial processes such as automobile manufacturing 2 , oil refinery 3 , battery facilities 4 , military wastes 5 , and fossil fuel combustion 6 . To decrease the level of exposure of human beings to Hg(II), a global agreement has been reached, spurring the research to remove and recover Hg(II) ions from industry wastewater 7 .…”

Mercury (Hg(II)) has been classified as a pollutant and its removal from aqueous sources is considered a priority for public health as well as ecosystem protection policies. Oxidized graphenes have attracted vast interest in water purification and wastewater treatment. In this report, a partially reduced graphene oxide is proposed as a pristine adsorbent material for Hg(II) removal. The proposed material exhibits a high saturation Hg(II) uptake capacity of 110.21 mg g−1, and can effectively reduce the Hg(II) concentration from 150 mg L−1 to concentrations smaller than 40 mg L−1, with an efficiency of about 75% within 20 min. The adsorption of Hg(II) on reduced graphene oxide shows a mixed physisorption–chemisorption process. Density functional theory calculations confirm that Hg atom adsorbs preferentially on clean zones rather than locations containing oxygen functional groups. The present work, therefore, presents new findings for Hg(II) adsorbent materials based on partially reduced graphene oxide, providing a new perspective for removing Hg(II).

“…Mercury is one of the most hazardous elements, and it spreads into the environment from many sources. The total amount of mercury emitted in nature was 2 500 ± 500 t/year in 2018, 1) and the mercury emitted in the environment does not disappear or fade away, instead, it changes its form, and exists in nature for decades. Mercury emissions are not only a local problem anymore; they spread across the world through the air, water, and even via the food chain, and adversely affect human health.…”

Evolution of Mercury from Iron Ores in Temperature-Programmed Heat Treatments

2022

The behavior of Hg released from iron ores during temperature-programmed heat treatments (TPHTs) in air has been mainly studied using an online monitoring method. The Hg release behavior in TPHT significantly depends on the type of ore being processed, which includes forms evolved as Hg 0 and Hg 2 + , and forms that remain thermally stable up to 950°C. In addition, the TPHT experiments for model Hg compounds suggested the presence of several types of Hg forms (HgCl 2 , Hg 2 Cl 2 , HgS, HgO, HgSO 4 , and associated mineral-Hg) in the iron ores used. The amounts and proportions of suggested forms of Hg species substantially depend on the type and composition of the iron ore used. These observations may be important in designing an efficient method for the removal of Hg from iron ore and gaseous Hg.

“…Mercury (Hg 2 + ) is an ubiquitous heavy-metal contaminant of the environment, which is easily absorbed by plants and can be accumulated in other organisms through the food chain. [1][2][3][4][5][6][7][8][9][10] In animals, Hg 2 + can prevent normal cellular function and generally induce severe health problems such as neural disorders, cognitive and motor disorders, kidney failure, abdominal pain, pink disease, DNA lesions, and even death. Due to the characteristic properties of Hg 2 + , it can combine with thiol groups in enzymes and proteins by passing through the biofilm.…”

A Naphthalimide‐Based Fluorescent Probe for the Detection and Imaging of Mercury Ions in Living Cells

The selective and efficient monitoring of mercury (Hg 2 + ) contamination found in the environment and ecosystem has been carried out. Thus, a new 1,8-naphthalimide-based fluorescent probe NADP for the detection of Hg 2 + based on a fluorescence enhancement strategy has been designed and synthesized. The NADP probe can detect Hg 2 + with high selectivity and sensitivity and a low detection limit of 13 nm.The detection mechanism was based on a Hg 2 + -triggered deprotection reaction, resulting in a dramatic change in fluorescence from colorless to green at physiological pH. Most importantly, biological investigation has shown that the NADP probe can be successfully applied to the monitoring of Hg 2 + in living cells and zebrafish with low cytotoxicity.
