This paper studies the interannual variability of pollution pathways from northern hemisphere (NH) continents into the Arctic. Using a 15-year model simulation of the dispersion of passive tracers representative of anthropogenic emissions from NH continents, we show that the North Atlantic Oscillation (NAO) exerts a strong control on the pollution transport into the Arctic, particularly in wint...

Environmental pollution due to heavy metals like mercury is of serious concern throughout the world. Due to anthropogenic activities, the concentration of mercury has increased in the environment. Though many methods are available for mercury removal, adsorption is considered as simple, economical and versatile method. In this paper the efficiency of mercury removal from aqueous solution using ...

The World Health Organization estimates that worldwide in 2012, nearly 7 million deaths occurred prematurely due to air pollution (1). In addition to respiratory and cardiovascular diseases, air pollution exposure is also linked to increased incidence of diabetes (2). Notably, the prevalence of diabetes and dyslipidemia escalated exponentially in the latter half of the 20th century coincident w...

The aim of this study was to assess the environmental impact of socio-cultural practices on the water quality of River Ganga at the foothills of the Garhwal Himalayas in Uttarakhand State, India. The physico-chemical parameters that contributed to the temporal variation and pollution in the river were identified in this study. Principal component analysis (PCA) and Cluster analysis (CA) were us...
