Assessment of natural background levels in potentially contaminated coastal aquifers.
The estimation of natural background levels (NBLs) of dissolved concentrations of target chemical species in subsurface reservoirs relies on a proper assessment of the effects of forcing terms driving flow and transport processes taking place within the system and whose dynamics drive background concentration values. We propose coupling methodologies based on (a) global statistical analyses and...
متن کاملNatural Boron Contamination in Mediterranean Groundwater
W ithin the past few decades, the water quality in many of the coastal aquifers along the Mediterranean Sea has rapidly degraded. Overexploitation of the groundwater basins, particularly during the tourist season, has resulted in the lowering of groundwater tables and increasing seawater intrusion into the aquifers. Countries such as Cyprus and Israel have shut down hundreds of wells along the ...
متن کاملNatural Variations in the Composition of Groundwater
It is commonly believed that the composition of groundwater does not change naturally. So if a change is recognized through taste and/or odor, many may think that something bad has happened. Perhaps the aquifer has become contaminated, or something is wrong with the well. However, a common cause of changes in water quality is through natural variations within the aquifer. What gives groundwater...
متن کاملHealth Risk Assessment of Natural Background Radiation in Residents of Khorramabad, Iran
Introduction Radioactive materials naturally exist in the world. Indeed, approximately 82% of human-absorbed radiation doses, which are out of human control, arise from natural sources of radiation including cosmic, terrestrial, and exposure through inhalation or ingestion. Thus, the aim of the present study was to estimate health risk, as well as the effective and organ doses from naturally oc...
متن کاملEffective dose from natural background radiation in Keffi and Akwanga towns, central Nigeria
Background: Human is exposed to radiation in their environment with or without their consent and the exposure to natural background radiation is an unpreventable event on earth. Materials and Methods: An in situ assessment of the indoor and outdoor background radiation in Akwanga and Keffi towns of Nasarawa state Nigeria was carried out using a halogen-quenched Geiger Muller (GM) detector (Insp...
