Mercury (Hg) is an extremely toxic pollutant, and its biogeochemical cycle has been perturbed by anthropogenic emissions during recent centuries. In the atmosphere, gaseous elemental mercury (GEM; Hg°) is the predominant form of mercury (up to 95%). Here we report the evolution of atmospheric levels of GEM in mid-to high-northern latitudes inferred from the interstitial air of firn (perennial snowpack) at Summit, Greenland. GEM concentrations increased rapidly after World War II from Ϸ1.5 ng m ؊3 reaching a maximum of Ϸ3 ng m ؊3 around 1970 and decreased until stabilizing at Ϸ1.7 ng m ؊3 around 1995. This reconstruction reproduces real-time measurements available from the Arctic since 1995 and exhibits the same general trend observed in Europe since 1990. Anthropogenic emissions caused a two-fold rise in boreal atmospheric GEM concentrations before the 1970s, which likely contributed to higher deposition of mercury in both industrialized and remotes areas. Once deposited, this toxin becomes available for methylation and, subsequently, the contamination of ecosystems. Implementation of air pollution regulations, however, enabled a large-scale decline in atmospheric mercury levels during the 1980s. The results shown here suggest that potential increases in emissions in the coming decades could have a similar large-scale impact on atmospheric Hg levels.atmosphere ͉ Greenland ͉ past century ͉ pollution

“…However, most of the mercury present in our atmosphere is the result of anthropogenic emissions, from sources such as burning coal, incineration of waste and chemical processing such as the Chlor-Alkali process. Anthropogenic emissions are thought to comprise up to two-thirds of all mercury emitted to the atmosphere [3][4][5] .…”

An analysis of total gaseous mercury (TGM) concentrations across the UK from a rural sampling network

Total gaseous mercury was collected at ten sites which comprise part of the UK rural . Using data from nine of the sites, we were able to show seasonality within the data and through kriging we were able to interpolate the TGM concentrations over the UK, revealing a south-east to north-west declining concentration gradient. Using continuous speciated mercury measurements from one of the network sites, we show through wind sector analysis and air-mass back trajectories that this spatial trend is likely to be due to air masses moving over the UK from continental Europe on easterly winds. The levels of TGM recorded in the south-east of the UK also more closely match observed background TGM levels on the continent, which could indicate that the TGM concentrations from the north of the UK are a better reflection of the true North Atlantic atmospheric mercury background level.

“…The major trace elements are associated with both natural and industrial processes (Gabrielli et al, 2008). The sources of industrial air pollution trace elements are different: fossil and oil combustion (As, Cu, Co, Cr, V, Ni, Sb, Fe, Mn, Zn, Sn, Mn, Pb, Fe, Ni); waste water management (Pb, Zn); steel production (Cr, Mn, Ni, Co); transport emissions (Pb, Cu, Cr, Sn, Sb) and others (Pacyna & Pacyna, 2001). The concentrations of trace element in troposphere are with high temporal and spatial variability (Melaku et al, 2008).…”

The growing economy with following industrialization and urbanization has led to environmental contamination with trace elements worldwide. In urban environment, the large inputs of anthropogenic contaminants in atmosphere are arising from mobile and stationary sources. The snow sample analysis is one of methods to monitor air contamination with heavy metals in urban areas. The aim of this research is to analyse heavy metal contamination and distribution in urban environment of Jelgava city. The samples were collected twice in January and February. Snow samples were collected in 20 urban area sampling plots and one natural area sampling plot with three repetitions taken from 1.0 to 1.5 kg of snow. The concentration of trace elements was estimated in 126 melted and filtrated snow water using inductively coupled plasma spectrometer (ICP-OES). The average heavy metals and nutrients concentrations were calculated for each sample. The concentrations data of trace elements were analysed using agglomerative hierarchical clustering method. The results show differences between results in January and February. The differences are related to anthropogenic impact intensity differences during the exposition periods of snow. The clustering results of snow samples taken in January show three clusters, but snow samples taken in February show four clusters.
