Cycling of Mercury in the Environment with Emphasis on the Importance of the Element in Acid Rain StudiesInformation on mercury and its environmentally significant chemical forms in the biogeochemical cycle is presented. Components of this cycle considered include the atmosphere, hydrometeors, surface ...
human healthplantsbioacumulationThe liquid metal, mercury, found in the nature, is increasing due to the anthropic activities not only in its organic but also its inorganic way. A general review about this metal is presented, including its cycle and impact in the environment and human health. ...
This book describes the extent of worldwide contamination by four important toxic elements: arsenic, cadmium, lead and mercury. It provides details on the pathways and rates at which these four elements cycle in the air, in soils, through crops and native ecosystems and in rivers, lakes and ...
Biogeochemical cycle of mercury in the environment: Analytical developments and speciation in estuarine milieu. Ph.D. Dissertation Reports on a technical report issued by the Committee on Environmental Health of the American Academy of Pediatrics on mercury toxicity in children that provides current infor...
Physical and chemical properties of the soil affect the Hg cycle in the environment. The soil aggregate size fractions have significant effects on the Hg content in soil. The concentrations of Hg and other heavy metals in soils and sediments generally tend to increase with decreasing grain size,...
The significance of volcanic emissions for the global atmospheric mercury cycle is not just that many of these emissions will tend to be into the free troposphere or, more rarely, the stratosphere, but that they may also constitute important natural point sources of particulate (Hgp) and reactive...
Mercury (Hg) is a global pollutant that bioaccumulates in aquatic food webs and leads to health issues for humans and wildlife1,2. Human activities have greatly increased Hg inputs to the global environment mainly through mining and industrial activities3. Anthropogenic Hg emissions to the atmosphe...
Mercury continues to circulate in the atmosphere, oceans, and terrestrial system for centuries to millennia before it returns to deep-ocean sediments. Areas of uncertainty in the global biogeochemical cycle of mercury include oxidation processes in the atmosphere, land-atmosphere and ocean-atmosphere ...
in the C-isotope composition of the reservoirs of the exogenic C cycle. The Hg concentration spike occurs in the same interval as the minimum in δ13C values associated with the PTME (EP. I, Fig.1). At Meishan, where the chronostratigraphic framework is well established33,34, the initial...
The Carnian Pluvial Episode (CPE) was a Late Triassic interval of global environmental changes and biological turnovers linked to C-cycle perturbation and global warming. Records of the CPE come mainly from low latitudes, and its impact at higher latitudes is poorly known. Here, we present ...
