“…The release of mercury into environments is mainly through discharge from industry products/byproducts and processes, such as chemicals, electronic materials, batteries and fossil fuel combustion 2 . A global agreement has recently been reached aiming at reducing mercury's threat, which spurs the research needed to remove and recover mercury ions from industry waste water 3 .…”

Mercury nano-trap for effective and efficient removal of mercury(II) from aqueous solution

et al. 2014

Highly effective and highly efficient decontamination of mercury from aqueous media remains a serious task for public health and ecosystem protection. Here we report that this task can be addressed by creating a mercury 'nano-trap' as illustrated by functionalizing a high surface area and robust porous organic polymer with a high density of strong mercury chelating groups. The resultant porous organic polymer-based mercury 'nano-trap' exhibits a recordhigh saturation mercury uptake capacity of over 1,000 mg g À 1 , and can effectively reduce the mercury(II) concentration from 10 p.p.m. to the extremely low level of smaller than 0.4 p.p.b. well below the acceptable limits in drinking water standards (2 p.p.b.), and can also efficiently remove 499.9% mercury(II) within a few minutes. Our work therefore presents a new benchmark for mercury adsorbent materials and provides a new perspective for removing mercury(II) and also other heavy metal ions from contaminated water for environmental remediation.

“…Implementation of the new Mercury and Air Toxics Standards (U.S. Environmental Protection Agency, 2011b) will control mercury emissions from U.S. coal-fired power plants, currently the largest source of mercury emissions in the United States. Internationally, implementation of recent Minamata Convention goals will control mercury emissions from mining, coal combustion, cement production, and numerous other sources (Lubick and Malakoff, 2013;United Nations Environment Programme, 2013b). As U.S. emissions are reduced, ecosystems within and close to major urban areas-which typically have large numbers of emission sources-will see greater reductions in mercury deposition than those in rural areas, where regional and global sources account for a greater proportion of total mercury deposition.…”

“…In January 2013, more than 140 United Nations member states, including the United States, agreed to a global, legally binding treaty to prevent emissions and releases of mercury to the atmosphere (Lubick and Malakoff, 2013;United Nations Environment Programme, 2013b). Known as the Minamata Convention on Mercury, the agreement provides controls and reductions across a wide range of products, processes, and industries where mercury is used, released, or emitted.…”

The quality of our nation's waters : mercury in the nation's streams-levels, trends, and implications / by Dennis A. Wentz, Mark E. Brigham, Lia C. Chasar, Michelle A. Lutz, and David P. Krabbenhoft. ForewordThe United States has made major investments in assessing, managing, regulating, and conserving natural resources, such as water, minerals, soil, and timber. Sustaining the quality of the Nation's water resources and the health of our ecosystems depends on the availability of sound water-resources data and information to develop effective, science-based policies. Effective management of water resources also brings more certainty and efficiency to important economic sectors. Taken together, these actions lead to immediate and long-term economic, social, and environmental benefits that make a difference to the lives of millions of people.The U.S. Geological Survey (USGS) is committed to providing the Nation with reliable scientific information that helps to enhance and protect the overall quality of life and that facilitates effective management of water, biological, energy, and mineral resources (http://www.usgs.gov). Information on water resources is critical to ensuring long-term availability of water that is safe for drinking and recreation, and that is suitable for industry, irrigation, and fish and wildlife. Population growth and increasing demands for water make the availability of water, measured in terms of quantity and quality, essential to the long-term sustainability of our communities and ecosystems.Mercury is a pervasive contaminant of streams and lakes, and has resulted in fish consumption advisories in all 50 States. The current report, "Mercury in the Nation's Streams-Levels, Trends, and Implications," presents a summary of results from USGS investigations conducted since the late 1990s on the sources, occurrence, trends, transport, and bioaccumulation of mercury in stream ecosystems. The report draws from studies conducted by several USGS Programs, including the National WaterQuality Assessment, Toxics Substances Hydrology, and National Research Programs. This report is one of a series of publications, The Quality of Our Nation's Waters, which describe major findings of the USGS on...

“…Industrial activities have increased the levels of Hg in the atmosphere and the oceans, and have contaminated some local environments, which cause decline of fish stocks (Nithyanandan et al, 2016). In the marine environment, Hg has long been recognized as a threat to human health (Withrow and Vail, 2007; Lubick and Malakoff, 2013) due to bioaccumulation and biologic transfer (biotransfer) of methylated toxic organic form with the formula CH 3 HgX. It is a dangerous family of compounds that are often found in polluted water and arise by a process known as biomethylation (NRC, 2000).…”

Total mercury (THg) and methylmercury (MeHg) were recorded in the commercial demersal fish Lethrinus nebulosus, caught from six locations in Qatar EEZ (Exclusive Economic Zone). Concentrations of THg decreased in the order: liver ˃ muscle ˃ gonad. THg concentrations in fish tissue ranged from 0.016 ppm in gonad to 0.855 ppm (mg kg−1 w/w) in liver tissues, while concentrations in muscle tissue ranged from 0.24 to 0.49 ppm (mg kg−1 w/w) among sampling sites. MeHg concentrations were used to validate food web transfer rate calculations. Intake rates were calculated to assess the potential health impact of the fish consumption. There is no major threat to human health from the presence of Hg in L. nebulosus, based upon reasonable consumption patterns, limited to no more than three meals of L. nebulosus per week.

Abstract: The Minamata Convention on Mercury seeks to curb or end most uses of mercury. It also calls for plenty of research.
