Elevated arsenic and manganese in groundwaters of Murshidabad, West Bengal, India

Arsenic availability in rice from a mining area: Is amorphous iron oxide-bound arsenic a source or sink?

“…Tracing back to the reason why amorphous iron oxide-bound As can be a good indicator of As availability to rice plants in paddy soils according to results from Hsu et al (2012), while our study showed contrary, this also should be related to the valence state of As. In the study of Hsu et al, As derived from As-containing groundwater most likely existed as As(III) dominantly (Sankar et al, 2014). Of course, there may be some other factors resulting in the difference in the availability of the amorphous iron oxide-bound As, which needs further studies.…”

Advances in Manganese Pollution and Its Bioremediation

“…High levels of manganese exposure in all forms have led to widespread health problems. The elevated intake of Mn is reported to cause detrimental health consequence, and in extreme amount, it is a neurotoxin where the newborn are principally at risk (Sankar et al 2014). It is well established that maternal exposure to Mn is linked with cellular abnormalities and Mn consumption through water is connected with neurotoxic possessions in kids.…”

Assessment of Arsenic Contamination in Deep Groundwater Resources of the Kathmandu Valley, Nepal

“…Significant variation in arsenic concentration among the seasons was observed in a study [46]. A study spotted no significant monsoonal effects on arsenic distribution [47]. The seasonal variability has little effect in the groundwater [48].…”
