About this Research Topic
Global issues on health are commonly associated with water. Water contains a variety of different ions, including dissolved metal(loids), which are acquired along its flow path under different physico chemical conditions, from different aquifer matrix. Apart from the natural contribution from the aquifer matrix, water also acquires these constituents as contaminants from domestic sewage, industrial effluents and agricultural fertilizers. These contaminants are generally absorbed/consumed by various aquatic organisms, even slightly elevated concentrations of certain metal(loids) and organic compounds are toxic and have adverse effect on the organism’s survival, activity, growth, metabolism, or reproduction. Similarly, nutrient enrichment affects the health of water bodies. Hence it is essential to understand the geochemical nature of metal(loids), nutrients and organic contaminants, in the health perspective, their origin/sources, mobility, seasonal variations, lithological influence, geospatial variations, etc., to manage the resource appropriately.
A wide range of treatment technologies are available for both surface and groundwater systems from micro to macro levels. Though it provides a sufficient quantity of treated drinking water, the sludge or the effluent from treatment plants also contribute to environmental damage. There are few in situ and cost effective, environment friendly treatment techniques to handle the contamination issues. Hence, this collection focuses on the sources, behavior and treatment of the metals in different aquatic environments.
This Research Topic will concentrate on different contaminants including; fluoride, arsenic, nitrate, phosphorus, uranium, mercury, tungsten, other metals of interest and metalloids. We aim to host a collection of articles on, but not limited to, the following relevant topics:
• Metal(loids), nutrients and organics pollution due to anthropogenic sources in aquatic environment and impact of land use pattern
• Metal(loids), nutrients and organics in water and their mobility and behaviors
• Geogenic contamination in groundwater, surfacewaters and human health
• Water preservation/treatment methods (in different levels; minor to macro)
• Coastal aquifers and metal contamination in terms of salinity issues.
Keywords: Metals, Organics, Treatment and Remediation, Mobilities of Contaminants in Groundwaters, Global Health, Sustainability
