      In the performed discriminant analysis potassium and ammonium ions were selected as components of the highest potential for classification of precipitation according to their acidity degree. All three applied chemometric techniques provided similar results confirming both the relevance of the obtained data and the appropriateness of the implemented techniques.

    2. Surveillance of Invasive Bacterial Pathogens and Human Enteric Viruses in Wastewater Final Effluents and Receiving Water Bodies – a Case Study from Durban, South Africa (pages 681–691)

      The results revealed that wastewater treatment plants exhibited effluent qualities that met acceptable standards with respect to temperature and pH whilst falling short of standard requirements for organic wastes such as turbidity, COD and nutrients which are critical to the provision of clean and safe water.

    3. Glutamic Acid Modified Fenton System for Degradation of BTEX Contamination (pages 692–697)

      Fatma Z. Yehia, Nadia G. Kandile, Abdelfatah M. Badawi and Amr H. Mady

      The results are consistent with the hypothesis that equation image radicals are the dominant reactive species in the modified Fenton system. However, the possible formation of iron–Glu chelates may protect the catalyst system from fast deactivation.

    4. Study of the Contributions of Non-Specific and Specific Interactions during Fluoxetine Adsorption onto Activated Carbons (pages 698–705)

      Silvia Román, João Manuel Valente Nabais, Juan Félix González, Carmen María González-García and Angel Luis Ortiz

      Version of Record online: 13 MAR 2012 | DOI: 10.1002/clen.201100009

      Fluoxetine adsorption experiments showed that in non-impregnated ACs the textural characteristics played a significant role, while in impregnated ACs the most relevant factor in the adsorption mechanism, probably the electrostatic interactions with an enhancement of chemical interactions.

    5. Landfill Leachate Treatment: A Case Study for Istanbul City (pages 706–711)

      Cevat Yaman, Huseyin Kurtulus Ozcan, Goksel Demir, Hatice Eser Okten, Senol Yildiz, Asli Coban and Vahit Balahorli

      The most widespread solid waste disposal method in Turkey and in the World is landfilling and a great amount of leachate is produced as a consequence. This study is considered to be a guide for construction and operation stages of proposed new treatment plants.

    6. The Spatial Variation and Factors Controlling the Concentration of Total Dissolved Iron in Rivers, Sanjiang Plain (pages 712–717)

      LiXia Wang, BaiXing Yan, XiaoFeng Pan and Hui Zhu

      Version of Record online: 29 MAR 2012 | DOI: 10.1002/clen.201100251

      In rivers, pH and DOC were controlling factors that affected the distribution and species change of the TDFe. Several farm activities would affect iron output. Therefore, some effective measures should be taken to protect wetland to maintain TDFe output.

    7. Kinetics, Mechanistic and Thermodynamics of Zn(II) Ion Sorption: A Modeling Approach (pages 718–727)

      Vishal Mishra, Chandrajit Balomajumder and Vijay Kumar Agarwal

      Version of Record online: 13 MAR 2012 | DOI: 10.1002/clen.201100093

      The biosorption potential of Cedrus deodara sawdust (CDS) for Zn(II) sorption across liquid phase has been evaluated. The results show that the intraparticle or pore diffusion of Zn(II) ion inside the pores of CDS was the rate limiting step at the later stage of contact time.

    8. Health Risk Assessment for Arsenic in Water Sources of Cankiri Province of Turkey (pages 728–734)

      This study indicated important health and cancer risks through exposure to arsenic (As) in water sources. For this reason, the paper suggests that the consumption of drinking water highly contaminated by As should be stopped. Conventional technologies such as iron containing coagulants must be used to treat As-contaminated water for As removal.

    9. Removal of Selenium Species from Waters Using Various Surface-Modified Natural Particles and Waste Materials (pages 735–745)

      Nevzat O. Yigit and Seda Tozum

      Version of Record online: 18 MAY 2012 | DOI: 10.1002/clen.201100740

      Surface modified adsorbent particles were prepared by iron oxide coating of natural pumice and volcanic slags and acid activation/heat treatment of ORM particles to test their Se uptakes from water. Se concentrations less than drinking water standards can be achieved by the use of iron oxide coated natural pumice or AARM particles.

    10. Bioreduction of Hexavalent Chromium by Live and Active Phanerochaete chrysosporium: Kinetics and Modeling (pages 746–751)

      From the present study it was evident that Phanerochaete chrysosporium can be suitably used for the bioreduction of lower concentration of chromium ions from water and wastewater in an environment friendly way.

      The efficient removal of phenanthrene from aqueous solution by carbon prepared from sesame stalks showed that sesame stalk-based carbon is a good sorbent with excellent capacity to sorb phenanthrene. At a carbon concentration of 10 mg/32 mL and a carbonization temperature of 700°C, the removal efficiency of phenanthrene approached 100%.
