Evaluation of chemical parameters of urban drinking water quality along with health risk assessment: A case study of ardabil province, iran

In recent years, in addition to water resources’ quantity, their quality has also received much attention. In this study, the quality of the urban water distribution network in northwestern Iran was evaluated using the water quality index (WQI) method. Then, some important trace elements were investigated, and finally, the health risk...

Multi-parametric assessment of biological stability of drinking water produced from groundwater: Reverse osmosis vs. conventional treatment

Although water produced by reverse osmosis (RO) filtration has low bacterial growth potential (BGP), post-treatment of RO permeate, which is necessary prior to distribution and human consumption, needs to be examined because of the potential re-introduction of nutrients/contaminants. In this study, drinking water produced from anaerobic...

Large-sample neutron activation analysis in mass balance and nutritional studies

Low concentrations of elements in food can be measured with various techniques, mostly in small samples (mg). These techniques provide only reliable data when the element is distributed homogeneously in the material to be analysed either naturally or after a homogenisation procedure. When this is not the case or homogenisation fails, a...

Analysis and Remediation of the Salinized, Damour Coastal (Dolomitic) Limestone Aquifer in Lebanon

Coastal aquifer management has recently emerged as a main scope in groundwater hydrology, especially in arid and semi-arid zones. About two thirds of the human population are currently gathered close to shorelines relying on coastal groundwater resources. Worldwide, these systems are subject to quality deterioration due to a multitude of...

Observations and prediction of recovered quality of desalinated seawater in the strategic ASR project in Liwa, Abu Dhabi

To be able to overcome water shortages, Abu Dhabi Emirate started an Aquifer Storage and Recovery (ASR) project with desalinated seawater (DSW) as source water near Liwa. It is the largest DSW-ASR project in the world (stored volume ~10 Mm³/year), and should recover potable water for direct use. DSW is infiltrated into a desert...

Parmelia sulcata lichen transplants positioning towards wind direction (Part I): Precipitation volumes, total element deposition and lichen element content

Parmelia sulcata transplants were used in three different exposure systems, focused on three different influxes: free influx, horizontal influx and vertical influx. The total element deposition and the precipitation volumes were found to be positively correlated for Fe and Ni only. The element contents in lichen transplants and in total element...

Parmelia sulcata lichen transplants positioning towards wind direction (Part II): Element concentrations and relationships with atmospheric element deposition

Parmelia sulcata transplants were positioned in three different exposure systems allowing three different influxes: free influx (Fi), horizontal influx (Hi) and vertical influx (Vi). Results suggest the absence of any wind-directional effects on element accumulation within Fi and Hi systems, but underline that differences in response may be...
