Journal ArticleDOI

Impact of irrigation with As rich groundwater on soil and crops: A geochemical case study in West Bengal Delta Plain, India

Stefan Norra, +5 more
- 01 Oct 2005 - 
TL;DR: In this article, the distribution of As was explored in soils and crops in order to investigate the influence of irrigation with As rich groundwater on the soil-plant system, and to determine its impact on the environment and human health.
Journal ArticleDOI

Temporal variability of trace metal mobility of urban particulate matter from Beijing – A contribution to health impact assessments of aerosols

Nina Schleicher, +7 more
- 01 Dec 2011 - 
TL;DR: In this paper, the total element concentration and the chemical fractionation of 18 elements (Al, As, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Ni, Pb, Rb, Sr, Ti, V, Zn) in total suspended particulate matter (TSP) from Beijing, China, were studied for a period of three years.
Journal ArticleDOI

Geochemical processes underlying a sharp contrast in groundwater arsenic concentrations in a village on the Red River delta, Vietnam

Elisabeth Eiche, +9 more
- 01 Nov 2008 - 
TL;DR: The spatial variability of As concentrations in aquifers of the Red River Delta, Vietnam, was studied in the vicinity of Hanoi as discussed by the authors, where two sites, only 700m apart but with very different As concentrations, were compared.
Journal ArticleDOI

Hydrogeological and biogeochemical constrains of arsenic mobilization in shallow aquifers from the Hetao basin, Inner Mongolia

Huaming Guo, +6 more
- 01 Apr 2011 - 
TL;DR: Results demonstrate that both drainage and irrigation channels produce oxygen-rich water that recharges shallow groundwaters and therefore immobilize As, and target aquifers for safe drinking water resources are available in alluvial fans and near irrigation channels.
Journal ArticleDOI

Long-term variation of black carbon and PM2.5 in Beijing, China with respect to meteorological conditions and governmental measures.

Yuan Chen, +8 more
- 01 May 2016 - 
TL;DR: Black carbon (BC) and PM2.5 were studied for nine years from 2005 to 2013 in the Beijing urban area and annual mean mass concentrations were reduced by 38% in 2013 compared to 2005, however, BC contamination in Beijing is still severe when compared to other urban areas around the world.
