This book was released on 2009-06-15 with total page 636 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mercury, primarily because of its existence and bioaccumulation as methylmercury in aquatic organisms, is a concern for the health of higher trophic level organisms, or to their consumers. This is the major factor driving current research in mercury globally and in environmental regulation, and is the driver for the current UNEP Global Partnership for Mercury Transport and Fate Research (UNEP F&T) initiative. The overall focus of the UNEP F&T report is to assess the relative importance of different processes/mechanisms affecting the transfer of mercury (Hg) from emission sources to aquatic and terrestrial receptors and provide possible source-receptor relationships. This transfer occurs through atmospheric transport, chemical transformations and subsequent deposition, and involves the intermittent recycling between reservoirs that occurs prior to ultimate removal of Hg from the atmosphere. Understanding the sources, the global Hg transport and fate, and the impact of human activity on the biosphere, requires improved knowledge of Hg movement and transformation in the atmosphere. An improved understanding of Hg emission sources, fate and transport is important if there is to be a focused and concerted effort to set priorities and goals for Hg emission management and reduction at the national, regional and global levels; and to develop and implement such policies and strategies. To achieve this, a series of coordinated scientific endeavors focused on the estimation of sources, measurement and validation of concentrations and processes, and modeling, coupled with interpretation of the results within a policy framework, is likely to be required.

Download or read book The Chemical Speciation and Phase Distribution of Atmospheric Oxidized Mercury written by Avik Ghoshdastidar and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Mercury is a potent global neurotoxin that causes cognitive and neuromuscular damage. it is released through natural and anthropogenic processes, such as fossil fuel combustion, and travels far from its source of origin. A global concern, 130 countries have signed the 2013 UN Convention on Mercury, committing to reducing emissions. Atmospheric mercury primarily exists as three bulk species of which gaseous elemental mercury (GEM) predominates. GEM travels far from its source of origin due to its long atmospheric residence time and deposits in marine and terrestrial environments following chemical transformation to the more water-soluble, bioavailable gaseous oxidized mercury (GOM) and after binding to particulates. In marine environments, oxidized forms of mercury may convert to the highly neurotoxic methylmercury organic species. Conventional mercury analysis techniques cannot determine the chemical forms of mercury present in the atmosphere only whether mercury is present as GEM, GOM or particulate forms. It is also not clear that what is measured as gaseous mercury is entirely gaseous but may be comprised of nano-particulate mercury. Nano-particulate mercury would have significantly different chemical, biologic and human health implications, and would fundamentally change how we model the fate of mercury in the atmosphere, its transformations and risks to ecosystems.In this work, we develop a technique to determine and measure the chemical speciation of atmospheric oxidized mercury using soft-ionization mass spectrometry, generate and characterize reproducible sources of oxidized mercury nanoparticles and assess the determine the gaseous and particulate contributions of mercury(II) bromide and mercury(II) chloride at pg/m3 concentrations in Montreal urban air.

Download or read book Air Mercury Speciation, Foliar Uptake, and Wash-off Along an Urban-rural Gradient written by Geoffrey W. Stupple and published by . This book was released on 2009 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mercury (Hg) is a contaminant of global concern due to its long-range atmospheric transport and high toxicity. The focus of this research is on the role of the forest canopy in the accumulation, and delivery of Hg to the soil Hg pool. Particular focus is on the role of atmospheric speciation of Hg on deposition. An urban-rural gradient was examined from Mississauga to Dorset, Ontario, to determine the role of locally emitted Hg: RGM, and PM on deposition. [GEM] was measured to be similar at both sites, and [PM] and [RGM] were greater in the urban location. Seasonal accumulation of Hg on foliar surfaces was dominated by GEM, and similar at the urban (8.74 ng cm -2) and rural (9.80 ng cm-2) locations. Increased [PM] and [RGM] at the urban location resulted in a transient upper canopy Hg pool, and throughfall enrichment at the urban site.

Available in PDF, EPUB and Kindle. Book excerpt: The challenges faced by the atmospheric research community today are vast, complex, and multi-faceted. The book Urban Atmospheric Aerosols: Sources, Analysis, and Effects highlights important aspects concerning the chemical and optical properties, size distribution, sources, and potential health effects of fine urban air particles (PM2.5). The physical and chemical characterization of PM2.5, its source assignment, and the assessment of the magnitude and distribution of its emissions are crucial for establishing effective fine air particle regulations and assessing the associated risks to human health. This book brings together eight papers covering the main topics of the field and will be of interest to researchers who are interested in air quality in outdoor and indoor environments, air particle toxicity, and atmospheric chemistry, as well as global climate modelers.

Available in PDF, EPUB and Kindle. Book excerpt: Mercury is a toxic global contaminant that is transported through the atmosphere, is deposited in terrestrial and aquatic ecosystems, and concentrates up the food chain, reaching levels that can harm both humans and wildlife. This book reports the latest findings describing the distribution, deposition, and measurement of this airborne pollutant as well as the human and environmental impacts of artisanal mining of mercury and gold. The research originates from around the world and highlights the importance of atmospheric mercury research and the Minamata Convention on Mercury, a global treaty to protect human health and the environment from anthropogenic emissions of mercury.

Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in air pollution monitoring and modeling capabilities have made it possible to show that air pollution can be transported long distances and that adverse impacts of emitted pollutants cannot be confined to one country or even one continent. Pollutants from traffic, cooking stoves, and factories emitted half a world away can make the air we inhale today more hazardous for our health. The relative importance of this "imported" pollution is likely to increase, as emissions in developing countries grow, and air quality standards in industrial countries are tightened. Global Sources of Local Pollution examines the impact of the long-range transport of four key air pollutants (ozone, particulate matter, mercury, and persistent organic pollutants) on air quality and pollutant deposition in the United States. It also explores the environmental impacts of U.S. emissions on other parts of the world. The book recommends that the United States work with the international community to develop an integrated system for determining pollution sources and impacts and to design effective response strategies. This book will be useful to international, federal, state, and local policy makers responsible for understanding and managing air pollution and its impacts on human health and well-being.

Available in PDF, EPUB and Kindle. Book excerpt: During the recent decades, social, political and academic endeavours have been made to improve environmental quality and reduce pollution. In particular, the ocean, sea and coastal areas show varying degrees of impact from the multiple human activities carried out in the terrestrial as well as in the aquatic environment. Ecology is a science which studies the relationship between organisms and the surrounding environment and in the modern era, the marine world is getting increasing attention. For centuries it has been the final reservoir of human garbage; later it became an oil farm with a concomitant increase of coastal population growth and unplanned growth of the fishing industry and the increasing use of sea routes for cargo transport and recreational uses (cruises). All this led to rising contamination with negative effects on biota and even human health. It is then imperative to know the current situation of the world's oceans: that is the main purpose of this book, to document at a glance the latest research in the field of ocean pollution.
