Environmental evidence of fossil fuel pollution in Laguna Chica de San Pedro lake sediments (Central Chile)

Pollution and eutrophication history AD 1800–2005 as recorded in sediments from five lakes in Central Chile

“…A general regional pattern of SCP deposition as it is known from Europe or North America (Rose, 2001) is hard to be identified for Central Chile. Our conclusions are in good agreement with those of Chirinos et al (2006) who describe SCP deposition in two lakes in the BioBío region 500 km to the south of Santiago. Two factors seem to be important: unlike in Europe or North-America, the industrial activity in Central Chile is (i) grouped around a few larger centres, whereby each of the sources has an individual history, and (ii) prevailing winds from the Pacific Ocean transport air masses with very-low-background concentrations of pollutants.…”

Does organic matter degradation affect the reconstruction of pre-industrial atmospheric mercury deposition rates from peat cores? — A test of the hypothesis using a permafrost peat deposit in northern Canada

“…Another problem with using an N-based ratio is that gaseous N pollution from biomass burning, fossil fuel combustion and denitrification of soil fertilizers has become a global problem, including remote regions such as the Arctic (e.g. Driscoll et al, 2003;Chirinos et al, 2006;AMAP, 2006;von Gunten et al, 2009). Significant N contamination of surface peat, which is not often examined in the peat literature, would mean that a comparison of C/N between modern and pre-industrial peat layers to judge OM humification may be compromised.…”

Spatial distribution and multiple sources of heavy metals in the water of Chaohu Lake, Anhui, China

“…In addition, the literature showed that coal combustion accounts for 46% of total atmospheric mercury, and emissions from natural sources and cement manufacturing represented two major contributors to the regional atmospheric mercury budget, contributing about 17% and 14%, respectively (Wang et al 2006). Rippey et al (2008), Chirinos et al (2006) and Rose and Rippey (2002) reported that high contents of the five heavy metal (Cu, Hg, Ni, Pb, and Zn) in profundal lake sediments is due to deposition from the atmosphere because of strong correlation between the concentration of the five metals and the concentration of SCPs, which are produced by fossil-fuel combustion. Similar findings are found in the literatures (Streets et al 2005;Pacyna and Pacyna 2002;Pirrone et al 2001;Veiga et al 1994).…”
