The development of models for understanding antibiotic resistance gene (ARG) persistence and transport is a critical next step toward informing mitigation strategies to prevent the spread in environment. A field study was performed that used mass balance approach gain insight into dissipation ARGs following land application manure. Soil from small drainage plot including manure site, an unmanured control adjacent stream buffer zone were sampled metals before after dairy slurry dry stack...
Abstract Activated sludge is the centerpiece of biological wastewater treatment, as it facilitates removal sewage-associated pollutants, fecal bacteria, and pathogens from through semi-controlled microbial ecology. It has been hypothesized that horizontal gene transfer spread antibiotic resistance genes within treatment plant, in part because presence residual antibiotics sewage. However, there surprisingly little evidence to suggest select for at plants via or otherwise. We addressed role...
Analysis of Hg(II) complexed by a soil humic acid (HA) using synchrotron-based X-ray absorption spectroscopy (XAS) revealed the importance reduced sulfur functional groups (thiol (R−SH) and disulfide (R−SS−R)/disulfane (R−SSH)) in substances complexation Hg(II). A two-coordinate binding environment with one oxygen atom at distances 2.02 2.38 Å, respectively, was found first coordination shell acid. Model calculations show that second sphere could contain carbon 2.78 2.93 respectively. This...
Abstract The binding of Hg 2+ in organic matter soils and waters controls the transport transformations terrestrial aquatic ecosystems. We developed a competitive complexation method using strong by Br − for determining strength at native elevated concentrations. distribution coefficients determined KBr suspensions sorption to soil carbon (SOC) ( K SOC ) are range 10 22 23 . significantly decreased with increased additions decreasing pH. Using data reduced S concentrations x‐ray absorption...
Abstract Sulfur K‐edge x‐ray absorption near‐edge structure spectroscopy (XANES) was used to identify multiple organic S oxidation states in aquatic and soil humic substances. The XANES results suggest that substances exists four major groups similar sulfate ester, sulfonate, sulfoxide, thiol‐sulfide. Thiol cannot be separated from sulfide must considered as a single thiol‐sulfide peak. second derivative spectra the existence of thiophene sulfone S. relative quantities each form our samples...
Efficient and selective dehydrogenation of formic acid is a key challenge for fuel-cell-based hydrogen economy. Though the development heterogeneous catalysts has received much progress, their catalytic activity remains insufficient. Moreover, design principle such are still unclear. Here, experimental theoretical studies on series mono-/bi-metallic nanoparticles supported NH2 -N-rGO substrate combined where surface energy metal taken as relevant indicator adsorption ability catalyst guiding...
Water reclamation provides a valuable resource for meeting nonpotable water demands. However, little is known about the potential wastewater reuse to disseminate antibiotic resistance genes (ARGs). Here, samples were collected seasonally in 2014–2015 from four U.S. utilities' reclaimed and potable distribution systems before treatment, after at five points of use (POU). Shotgun metagenomic sequencing was used profile resistome (i.e., full contingent ARGs) subset (n = 38) samples. Four ARGs...
The spread of antibiotic resistance is a growing public health concern. While numerous studies have highlighted the importance environmental sources and pathways resistance, systematic means comparing prioritizing risks represented by various compartments lacking. Here, we introduce MetaCompare, publicly available tool for ranking 'resistome risk', which define as potential genes (ARGs) to be associated with mobile genetic elements (MGEs) mobilize pathogens based on metagenomic data. A...
Manure-derived amendments are commonly applied to soil, raising questions about whether antibiotic use in livestock could influence the soil resistome (collective resistance genes (ARGs)) and ultimately contribute spread of humans during food production. Here, we examined metagenomes soils amended with raw or composted manure generated from dairy cows administered pirlimycin cephapirin (antibiotic) no antibiotics (control) relative unamended soils. Initial amendment (Day 1) compost...
With widespread detection of endocrine disrupting compounds including hormones in wastewater, there is a need to develop cost-effective remediation technologies for their removal from wastewater. Previous research has shown that Fe3+-saturated montmorillonite effective quickly transforming phenolic organic such as pentachlorophenol, acids, and triclosan via surface-catalyzed oligomerization. However, little known about its effectiveness reaction mechanisms when reacting with hormones. In...
Biochars are added to soil improve agronomic yield. This greenhouse- and field-scale study evaluated polycyclic aromatic hydrocarbon (PAH) contamination in 35 commercial laboratory-produced biochars, assessed the effects of biochar amendment soils on PAH accumulation vegetables risk for cancer. The total bioavailable concentrations biochars varied from 638 12,347 μg/kg below detection limit (BDL) 2792 μg/kg, respectively. formation decreased with increasing production temperature (350–650...
In the context of stalling progress against malaria, resistance mosquitoes to insecticides, and residual transmission, mass drug administration (MDA) ivermectin, an endectocide used for neglected tropical diseases (NTDs), has emerged as a promising complementary vector control method. Ivermectin reduces life span
Abstract Ambient electrochemical ammonia (NH 3 ) synthesis is one promising alternative to the energy‐intensive Haber–Bosch route. However, industrial requirement for NH production with amperes current densities or gram‐level yield remains a grand challenge. Herein, we report high‐rate via NO 2 − reduction using Cu activated Co electrode in bipolar membrane (BPM) assemble electrolyser, wherein BPM maintains ion balance and liquid level of electrolyte. Benefited from abundant sites optimal...
The traditional method for synthesizing NH 3 is the Haber–Bosch process which results in high‐fuel consumption and environmental pollution. Therefore, ecofriendly electrochemical synthesis of through nitrate (NO − ) reduction a good choice. Herein, an integral Au/Cu electrode to catalyze NO introduced. catalyst exhibits not only highest yield rate (73.4 mg h −1 cm −2 up now but also very high Faradaic efficiency 98.02% at −0.7 V room temperature. It commonly believed that transformation...
Abstract Background Residual malaria transmission is the result of adaptive mosquito behavior that allows vectors to thrive and sustain in presence good access bed nets or insecticide residual spraying. These behaviors include crepuscular outdoor feeding as well intermittent upon livestock. Ivermectin a broadly used antiparasitic drug kills mosquitoes on treated subject for dose-dependent period. Mass administration with ivermectin has been proposed complementary strategy reduce...
Seafood samples from the fishing ground closure areas of Mississippi Gulf Coast that were affected by Deepwater Horizon Oil Spill Disaster collected and analyzed for twenty-five 2- to 6-ring PAHs, about one month after first day incident. A total 278 seafood consisting 86 fishes, 65 shrimps, 59 crabs, 68 oysters weekly May 27, 2010 until October monthly thereafter August 2011. Statistically higher levels PAHs detected in all four types during early part sampling period compared later months....
Manure composting has general benefits for production of soil amendment, but the effects on antibiotic persistence and antibiotics process are not well‐characterized, especially commonly used in dairy cattle. This study provides a comprehensive, head‐to‐head, replicated comparison effect static turned typical beef cattle their actual excreted form corresponding influence efficacy. from steers (with or without chlortetracycline, sulfamethazine, tylosin feeding) cows pirlimycin cephapirin...
