Emerging investigator series: towards a framework for establishing the impacts of pharmaceuticals in wastewater irrigation systems on agro-ecosystems and human health
Use of reclaimed wastewater for agricultural irrigation is seen as an attractive option to meet agricultural water demands of a growing number of countries suffering from water scarcity.
Emerging investigator series: mercury mobility and methylmercury formation in a contaminated agricultural flood plain: influence of flooding and manure addition
We investigated the release of mercury from soil to soil solution and the formation of methylmercury in polluted agricultural floodplain fields during a flooding incubation experiment.
Emerging investigator series: interdependency of green rust transformation and the partitioning and binding mode of arsenic
Structural transformations of green rust and the partitioning of arsenic were tracked during aging for up to a year.
Degradation of phthalate esters in floor dust at elevated relative humidity
Emerging investigator series: Phthalate losses in floor dust are due to abiotic chemical degradation as well as microbial degradation of phthalates under elevated relative humidity conditions.
Emerging investigator series: primary emissions, ozone reactivity, and byproduct emissions from building insulation materials
Insulation materials affect indoor air by (i) releasing primary volatile organic compounds (VOCs) from enclosure cavities to the interior space, (ii) mitigating exposure to outdoor pollutants through reactive deposition (of oxidants, e.g., ozone) or filtration in infiltration air, and (iii) generating secondary VOCs and gas-phase byproducts from chemical reactions.
Emerging investigator series: spatial distribution of dissolved organic matter in ice and at air–ice interfaces
Organic solutes in snow and ice can be distributed heterogeneously throughout the ice bulk and across the ice surface. This may affect air-surface interactions and heterogeneous reactions in snow-covered regions.
Emerging investigator series: investigation of mercury emission sources using Hg isotopic compositions of atmospheric mercury at the Cape Hedo Atmosphere and Aerosol Monitoring Station (CHAAMS), Japan
This study conducted mercury (Hg) isotopic analysis, which has been expected as a new indicator for understanding the behavior of atmospheric Hg.
Emerging investigator series: oxidative potential of diesel exhaust particles: role of fuel, engine load, and emissions control
Biodiesel and the use of an emissions control system significantly reduced the oxidative potential of diesel exhaust particles, which correlated with reduction in emissions of elemental carbon.
Emerging investigator series: atmospheric cycling of indium in the northeastern United States
Atmospheric indium is dominated by human emissions, primarily from coal combustion and the smelting of lead, zinc, and other metal sulfides.
Emerging investigator series: radium accumulation in carbonate river sediments at oil and gas produced water discharges: implications for beneficial use as disposal management
In the western U.S., produced water from oil and gas wells discharged to surface water augments downstream supplies used for irrigation and livestock watering.
Emerging investigator series: effect-based characterization of mixtures of environmental pollutants in diverse sediments
Our study distinguishes the total vs. the bioavailable contamination of mixtures of environmental pollutants in sediments from contaminated sites in Europe and more remote locations in Australia and the Arctic.
Emerging investigator series: exploring the surface properties of aqueous aerosols coated with mixed surfactants
Fatty acid monolayers form in a more well-ordered state upon mixing with cholesterol at the air–seawater surface.
Emerging investigator series: determination of biphasic core–shell droplet properties using aerosol optical tweezers
Algorithm to fit whispering gallery modes retrieves biphasic properties.
Emerging investigator series: sunlight photolysis of 2,4-D herbicides in systems simulating leaf surfaces
Herbicides in the 2,4-D family were investigated for their direct photolysis under sunlight in organic solvents and on simulated leaf surfaces.
Emerging investigator series: methylmercury speciation and dimethylmercury production in sulfidic solutions
Experimental and computational evidence show that dimethylmercury is produced from decomposition of bis(methylmercury(II)) sulfide.
Emerging investigator series: geochemistry of trace elements associated with Fe and Mn nodules in the sediment of limed boreal lakes
We report on the geochemical legacy of the liming of acidified lakes in Norway. We document the occurrence of Fe–Mn nodules and the diagenetic redistribution of trace-elements at the sediment–water interface of limed boreal lakes.
Emerging investigator series: the effect of wildfire on streamwater mercury and organic carbon in a forested watershed in the southeastern United States
The amount of streamwater mercury associated with suspended solids was an order of magnitude greater following a low-intensity wildfire.
Emerging investigator series: development and application of polymeric electrospun nanofiber mats as equilibrium-passive sampler media for organic compounds
We fabricated a suite of polymeric electrospun nanofiber mats (ENMs) and investigated their performance as next-generation passive sampler media for environmental monitoring of organic compounds.
Emerging investigator series: As(V) in magnetite: incorporation and redistribution
As coprecipitated with magnetite remained incorporated over time whereas sorbed As was redistributed and became increasingly incorporated into magnetite, both the absence and presence of aqueous Fe(II).
Emerging investigator series: dual role of organic matter in the anaerobic degradation of triclosan
Organic matter affects the degradation of triclosan as both a sequester and an electron shuttle.
Emerging investigator series: a 14-year depositional ice record of perfluoroalkyl substances in the High Arctic
Detection of perfluoroalkyl substances from a remote ice cap indicate the importance of indirect and novel direct atmospheric sources.
