Multivariate Statistical Analyses of Groundwater Hydrochemical Data of Tirnavos Sub-basin (Central Greece)
(Corresponding) Vrouhakis I., Pisinaras V., Panagopoulos A., Stamatis G.
Topic:
Enviornmental data analysis and modelling
Abstract. Principal Component Analysis (PCA) and Hierarchical Cluster Analysis (HCA) were applied in the groundwater hydrochemical parameters dataset of the Tirnavos alluvial sub basin-central Greece. PCA results suggest occurrence of four principal components both for dry and wet periods. Results...Read more

Long-term impact of use of treated wastewater on accumulation of metals in soil.
(Corresponding) Elsergany M., KARKAIN R., DIAMADAPOULOS E., Moussa M.
Topic:
Water and wastewater reuse
The aim of this paper is to assess the environmental risks associated with the wastewater reuse with respect to six metals; cadmium (Cd), chromium (Cr), copper (Cu), nickel (Ni), lead (Pb) and zinc (Zn) in the city of Dubai. Treated Sewage Effluent (TSE) is used for landscape irrigation. Samples of...Read more

Grey Water and Rain Water as Alternative Sources of Flush Water and Irrigational Water in and around Households: A Case Study from Istanbul Atakoy District
(Corresponding) BELER BAYKAL B., GURSOY O., AKSOY Y., SAMSUNLU A.
Topic:
Water and wastewater reuse
Grey water and rain water are two options as alternative sources to alleviate water stress/scarcity across the world. This paper aims to investigate possible use of reclaimed grey water and harvested rain water from on-site premises as sources of flush water and irrigational water in and around...Read more

Rainwater harvesting from roads enhanced indigenous pasture establishment in a typical African dryland environment
(Corresponding) Mganga K.
Topic:
Water management in arid communities/places
African drylands are a key source forage for pastoral livestock herds. However, land degradation and recurrent droughts have resulted to shrinkage of natural grazing pastures. This poses the greatest challenge to livestock production in African drylands. Combining innovative sustainable land...Read more
Dioxin-Like Polychlorinated Biphenyls at Dilijan Landfills (Republic of Armenia)
(Corresponding) Aleksandryan A., KHACHATRYAN A., Bunyatyan Y.
Topic:
Emerging pollutants
Polychlorinated biphenyls (PCBs) are substances of wide distribution, high toxicity, persistence, and ability to long-distance migration. They are characterized by unique properties: temperature stability; high boiling point; non-combustibility; resistance to chemical and physical influences; high...Read more
Investigating the Potential of UV-excited Photoluminescence Spectroscopy for the Identification of Plastics
Gies S., Schömann E., Radiev Y., Prume J., (Corresponding) Koch M.
Topic:
Microplastics in the marine environment
In this study, we investigate photoluminescence (PL) spectroscopy with UV excitation as an alternative method for the detection and identification of plastic materials. The PL is excited at 266 nm. Spectra of the most widely used plastic materials are analyzed. Based on these results, it should be...Read more
Treatment of High Strength Industrial Wastewater utilizing Canna X generalis in a Simulated Vertical Flow Constructed Wetland Set-up
(Corresponding) Ballesteros F., Antonio H., Esguerra G.
Topic:
Wastewater treatment
In the Philippines, DENR has mandated the regulation of oil and grease, COD, and TSS for automotive parts manufacturers. Wastewaters from industries have varying pollution strength that requires efficient treatment systems of combined physical, biological, and chemical processes. However, these...Read more

(Corresponding) Rao Z., liang m., Liu L., Gong J., Zhu T.
Topic:
Emerging pollutants
Screening of 102 organic pollutants in groundwater along the Beijing-Hangzhou Grand Canal in China by GC×GC-TOFMS. A total of 45 samples were collected. The targets of the investigation involve multiple types of organic pollutants such as Polycyclic aromatic hydrocarbons (PAHs) and their...Read more
WATER SALINIZATION IN IRAN: SPATIAL VARIATION OF SALINITY IN GROUNDWATER RESOURCES OF NORTH WEST (URMIA LAKE)
Shakerkhatibi M., Jahanimoghaddam H., Esmat Saatloo M., (Corresponding) Mosaferi M.
Topic:
Water policy, management and society
This study presents the quality of drinking water in terms of salinity in the western margin of Lake Urmia, Iran. During the study a total of 121 samples from 116 wells and 5 springs were collected which constitute drinking water resources of 301 villages in the study area. Approximately more than...Read more

Reduction of Halogenated Organic Compounds in Water: Comparison of Available Reduction Systems based on Cu, Pd and ZVI
(Corresponding) Shee A., Kopinke F., Mackenzie K.
Topic:
Water treatment
Catalysts on the basis of copper (Cu) and the reducing agent borohydride (BH4-) have been successfully used for reduction of chlorinated aliphatics with low substitution degree which are usually resistant to zero-valent iron (ZVI) and hydrodehalogenation catalysts, such as Pd. Reactivity screening...Read more
