“…There are three anomalously high sites that fall between 3-9 g/L which are found in the shallow part of the aquifer system, and these higher concentrations could be related to recent Holocene deposits and/or regions of 408 lower aquifer flushing (Shamsudduha et al, 2015). In contrast, much higher arsenic 409 concentrations in groundwater have been reported for parts of southern Punjab and Chandigarh,410 to the southeast of the study area (Chakraborti et al, 2016) and over much of the region (Hundal 411 et al, 2009;Kumar et al, 2016;Sharma et al, 2013)…”

Groundwater depletion has been widely studied in northwest India, but water quality concerns are still poorly constrained. In this study, we explore the hydrochemistry of the top 160m of the aquifer system, through detailed field studies in the Bist-Doab region, considering both anthropogenic and geogenic controls. A detailed comparison is made between sites dominated by urban and agricultural landuse. Salinity, nitrate, chloride and lead concentrations are significantly higher in the shallow (0-50m) groundwater system due to surface anthropogenic contaminant loading from agricultural and urban sources. The widespread occurrence of oxic groundwater within the aquifer system means that denitrification potential is limited and also enhances the mobility of selenium and uranium in groundwater. Geogenic trace elements (e.g. As, Se, F), are generally found at concentrations below WHO guideline drinking water values, however elevated U concentrations (50-70μg/L) are found within the deeper part of the aquifer and shallow urban aquifers associated with higher bicarbonate waters. Higher concentration of Se (10-40μg/L) are found exclusively in the shallow groundwater system where Se is mobilised from soils and transported to depth in the shallow aquifer due to the prevailing oxidising aquifer conditions. New evidence from a range of environmental tracers shows elevated concentrations of anthropogenic contaminants in the deeper part of the aquifer (50-160m deep) and demonstrates vulnerability to vertical migration of contaminants. Continued intensive groundwater abstraction from >100m deep means that water quality risks to the deep aquifer system need to be considered together with water quantity constraints.

“…Therefore, we can say that As III that accumulated in the S. molesta floating and submerged leaves promoted oxidative stress and cell damage in plants. Although cellular damage occurred only 24 h after exposure to treatments, the As III concentrations used in this test are much higher than those naturally found in regions where there are water sources with high levels of As contamination (Chakraborti et al 2016c).…”

Role of glutathione in tolerance to arsenite in Salvinia molesta, an aquatic fern

In many plant species, tolerance to toxic metals is highly dependent on glutathione, an essential metabolite for cellular detoxifi cation. We evaluated the responses of glutathione metabolism to arsenite (As III) in Salvinia molesta, an aquatic fern that has unexplored phytoremediation potential. Plants were exposed to diff erent As III concentrations in nutrient solution for 24 h. As III caused cell membrane damage to submerged leaves, indicating oxidative stress. Th ere was an increase in the glutathione content and ϒ-glutamylcysteine synthetase enzyme activity in the submerged and fl oating leaves. Th e glutathione peroxidase and glutathione sulfotransferase enzymes also showed increased activity in both plant parts, whereas glutathione reductase only showed increased activity in the submerged leaves. Th ese fi ndings suggest an important role for glutathione in the protection of S. molesta against the toxic eff ects of As III , with more eff ective tolerance responses in the fl oating leaves.

“…Several epidemiologic studies have been performed later to identify and counter attack arsenic and arsenic related problems. Currently, over 500 million people are living in the red zone of arsenic exposure only in South Asia [27]. Recently, contamination of arsenic with foods has been a great challenge for the current health care associates [28].…”

In this recent era, occupational and accidental spills have been dramatically increased since last few decades due to globalization throughout the world. Concurrently, the concerns on health issues are being a burning question to the all corporate as well as health care professional personnel. Currently, arsenic and arsenic related problems have drawn a great attention as this compound acts not only as slow poison but also works as beneficial molecule in the treatment of some diseases. Laboratory animals showed several dysfunctions including keratinocytes dysfunctions, loss of hair and most importantly inflammation. Arsenic-mediated cell stress/oxidative stress also plays a major role in the development of multiple pathways like JNK, AP-1, PKC and caspase which further either lead to apoptosis or cancer. Countries like Bangladesh, India, Mexico, Chile and China are in great risk and the human from these areas are losing their lives due to chronic arsenic exposures. Therefore, this study will try to explain the proposed molecular mechanisms of arsenic-induced skin diseases, hair fall and inflammation. Finally, a possible treatment approach would be disclosed against arsenic-mediated disorders.
