Exposure to the Contraceptive Progestin, Gestodene, Alters Reproductive Behavior, Arrests Egg Deposition, and Masculinizes Development in the Fathead Minnow (Pimephales promelas)

19-May-2016 | Tyler E. Frankel; Michael T. Meyer; Dana W. Kolpin; Amanda B. Gillis; David A. Alvarez; Edward F. Orlando, Environmental Science & Technology, 2016

Endogenous progestogens and pharmaceutical progestins enter the environment through wastewater treatment plant effluent and agricultural field runoff. Lab studies demonstrate strong, negative exposure effects of these chemicals on aquatic vertebrate reproduction. Behavior can be a sensitive, ...

Wastewater Treatment Works (WwTW) as a Source of Microplastics in the Aquatic Environment

18-May-2016 | Fionn Murphy; Ciaran Ewins; Frederic Carbonnier; Brian Quinn, Environmental Science & Technology, 2016

Municipal effluent discharged from wastewater treatment works (WwTW) is suspected to be a significant contributor of microplastics (MP) to the environment as many personal care products contain plastic microbeads. A secondary WwTW (population equivalent 650 000) was sampled for microplastics at ...

Ultrathin Free-Standing Bombyx mori Silk Nanofibril Membranes

17-May-2016 | Shengjie Ling; Kai Jin; David L. Kaplan; Markus J. Buehler, Nano Letters, 2016

We report a new ultrathin filtration membrane prepared from silk nanofibrils (SNFs), directly exfoliated from natural Bombyx mori silk fibers to retain structure and physical properties. These membranes can be prepared with a thickness down to 40 nm with a narrow distribution of pore sizes ...

Materials, Vol. 9, Pages 364: Effective Degradation of Aqueous Tetracycline Using a Nano-TiO2/Carbon Electrocatalytic Membrane

12-May-2016 | Liu, Zhimeng ; Zhu, Mengfu ; Wang, Zheng ; Wang, Hong ; Deng, Cheng ; Li, Kui, Materials, 2016

In this work, an electrocatalytic membrane was prepared to degrade aqueous tetracycline (TC) using a carbon membrane coated with nano-TiO2 via a sol-gel process. SEM, XRD, EDS, and XPS were used to characterize the composition and structure of the electrocatalytic membrane. The effect of ...

Use of Shewanella oneidensis for Energy Conversion in Microbial Fuel Cells

06-May-2016 | A. Belen Jorge, Rachael Hazael, Macromolecular Chemistry and Physics, 2016

Anaerobes are a unique class of organisms, they were able to survive the heavy bombardment of the Archean period by reducing various inorganic compounds to support their metabolism and drive respiration in the early Earth's oxygen poor environment. Of all the bacteria that evolved during this ...

Photoinactivation of Eight Health-Relevant Bacterial Species: Determining the Importance of the Exogenous Indirect Mechanism

06-May-2016 | Peter A. Maraccini; Jannis Wenk; Alexandria B. Boehm, Environmental Science & Technology, 2016

It is presently unknown to what extent the endogenous direct, endogenous indirect, and exogenous indirect mechanisms contribute to bacterial photoinactivation in natural surface waters. In this study, we investigated the importance of the exogenous indirect mechanism by conducting ...

Determining Multiple Responses of Pseudomonas aeruginosa PAO1 to an Antimicrobial Agent, Free Nitrous Acid

04-May-2016 | Shu-Hong Gao; Lu Fan; Lai Peng; Jianhua Guo; Míriam Agulló-Barceló; Zhiguo Yuan; Philip L. Bond, Environmental Science & Technology, 2016

Free nitrous acid (FNA) has recently been demonstrated as an antimicrobial agent on a range of micro-organisms, especially in wastewater-treatment systems. However, the antimicrobial mechanism of FNA is largely unknown. Here, we report that the antimicrobial effects of FNA are multitargeted. The ...

Electrospun Differential Wetting Membranes for Efficient Oil–Water Separation

29-Apr-2016 | Venkatesan Anand Ganesh, Anupama Sargur Ranganath, Avinash Baji, Him Cheng Wong, Hemant Kumar Raut, Rahul Sahay, See ..., Macromolecular Materials and Engineering, 2016

Separation of low viscous oil from water has attracted immense attention in recent times due to the ever‐increasing amount of oily industrial wastewater discharge and frequent oil spill accidents. Hence, there is a persistent demand for the fabrication of robust oil–water separation membranes. ...

Immobilization and enhanced catalytic activity of lipase on modified MWCNT for oily wastewater treatment

29-Apr-2016 | Ammar Jamie, Ali S. Alshami, Zuhair O. Maliabari, Muataz Ali Ateih, Othman Charles S. Al Hamouz, Environmental Progress, 2016

In this article, we report results of experiments on covalent immobilization of Candidia rugosa lipase enzyme on modified multiwall carbon nanotubes (MW‐CNTs) for oily wastewater treatment application. MWCNTs were produced using chemical vapor deposition (CVD) and surface‐modified by nitric acid ...
