Influence of Multiple Environmental Factors on Organic Matter Chlorination in Podsol Soil

12-Dec-2017 | Teresia Svensson; Malin Montelius; Malin Andersson; Cecilia Lindberg; Henrik Reyier; Karolina Rietz; Åsa Danielsson; ..., Environmental Science & Technology, 2017

Natural chlorination of organic matter is common in soils. The abundance of chlorinated organic compounds frequently exceeds chloride in surface soils, and the ability to chlorinate soil organic matter (SOM) appears widespread among microorganisms. Yet, the environmental control of chlorination ...

Mapping the Reactions in a Single Zero-Valent Iron Nanoparticle

12-Dec-2017 | Lan Ling; Xiaoyue Huang; Meirong Li; Wei-xian Zhang, Environmental Science & Technology, 2017

Nanoscale zerovalent iron (nZVI) possesses unique functionalities for metal–metalloid removal and sequestration. So far, direct evidence on the heavy metal–nZVI reactions in the solid phase is still limited due to low concentration of heavy metals and small size of nanoparticles. In this work, ...

Highly Efficient Interception and Precipitation of Uranium(VI) from Aqueous Solution by Iron-Electrocoagulation Combined with Cooperative Chelation by Organic Ligands

12-Dec-2017 | Peng Li; Bao Zhun; Xuegang Wang; PingPing Liao; Guanghui Wang; Lizhang Wang; Yadan Guo; Weimin Zhang, Environmental Science & Technology, 2017

A new strategy combining iron-electrocoagulation and organic ligands (OGLs) cooperative chelation was proposed to screen and precipitate low concentrations (0–18.52 μmol/L) of uranium contaminant in aqueous solution. We hypothesized that OGLs with amino, hydroxyl, and carboxyl groups ...

Relative Contribution of nirK- and nirS- Bacterial Denitrifiers as Well as Fungal Denitrifiers to Nitrous Oxide Production from Dairy Manure Compost

11-Dec-2017 | Koki Maeda; Sakae Toyoda; Laurent Philippot; Shohei Hattori; Keiichi Nakajima; Yumi Ito; Naohiro Yoshida, Environmental Science & Technology, 2017

The relative contribution of fungi, bacteria, and nirS and nirK denirifiers to nitrous oxide (N2O) emission with unknown isotopic signature from dairy manure compost was examined by selective inhibition techniques. Chloramphenicol (CHP), cycloheximide (CYH), and diethyl dithiocarbamate (DDTC) ...

Strategic Materials in the Automobile: A Comprehensive Assessment of Strategic and Minor Metals Use in Passenger Cars and Light Trucks

11-Dec-2017 | Frank R. Field, III; Timothy J. Wallington; Mark Everson; Randolph E. Kirchain, Environmental Science & Technology, 2017

A comprehensive component-level assessment of several strategic and minor metals (SaMMs), including copper, manganese, magnesium, nickel, tin, niobium, light rare earth elements (LREEs; lanthanum, cerium, praseodymium, neodymium, promethium, and samarium), cobalt, silver, tungsten, heavy rare ...

Surrogate-Based Correlation Models in View of Real-Time Control of Ozonation of Secondary Treated Municipal Wastewater—Model Development and Dynamic Validation

11-Dec-2017 | Michael Chys; Wim T. M. Audenaert; Emma Deniere; Séverine Thérèse F. C. Mortier; Herman Van Langenhove; Ingmar Nopen ..., Environmental Science & Technology, 2017

New robust correlation models for real-time monitoring and control of trace organic contaminant (TrOC) removal by ozonation are presented, based on UVA254 and fluorescence surrogates, and developed considering kinetic information. The abatement patterns of TrOCs had inflected shapes, controlled ...

Aerosol Health Effects from Molecular to Global Scales

27-Nov-2017 | Manabu Shiraiwa; Kayo Ueda; Andrea Pozzer; Gerhard Lammel; Christopher J. Kampf; Akihiro Fushimi; Shinichi Enami; An ..., Environmental Science & Technology, 2017

Poor air quality is globally the largest environmental health risk. Epidemiological studies have uncovered clear relationships of gaseous pollutants and particulate matter (PM) with adverse health outcomes, including mortality by cardiovascular and respiratory diseases. Studies of health impacts ...

Advances in Sulfidation of Zerovalent Iron for Water Decontamination

27-Nov-2017 | Jinxiang Li; Xueying Zhang; Yuankui Sun; Liping Liang; Bingcai Pan; Weiming Zhang; Xiaohong Guan, Environmental Science & Technology, 2017

Sulfidation has gained increasing interest in recent years for improving the sequestration of contaminants by zerovalent iron (ZVI). In view of the bright prospects of the sulfidated ZVI (S-ZVI), this review comprehensively summarized the latest developments in sulfidation of ZVI, particularly ...

Characterization of Individual Isopropylated and tert-Butylated Triarylphosphate (ITP and TBPP) Isomers in Several Commercial Flame Retardant Mixtures and House Dust Standard Reference Material SRM 2585

13-Nov-2017 | Allison L. Phillips; Stephanie C. Hammel; Alex Konstantinov; Heather M. Stapleton, Environmental Science & Technology, 2017

Since the phase-out of pentaBDE in the early 2000s, replacement flame-retardant mixtures including Firemaster 550 (FM 550), Firemaster 600 (FM 600), and organophosphate aryl ester technical mixtures have been increasingly used to treat polyurethane foam in residential upholstered furniture. These ...

DGT Passive Sampling for Quantitative in Situ Measurements of Compounds from Household and Personal Care Products in Waters

11-Nov-2017 | Wei Chen; Yanying Li; Chang-Er Chen; Andrew J. Sweetman; Hao Zhang; Kevin C. Jones, Environmental Science & Technology, 2017

Widespread use of organic chemicals in household and personal care products (HPCPs) and their discharge into aquatic systems means reliable, robust techniques to monitor environmental concentrations are needed. The passive sampling approach of diffusive gradients in thin-films (DGT) is developed ...
