Highlighting early career scientists
The Editors introduce the Emerging Investigator issue with news of a new Emerging Investigator Series from 2017.
Contributors to the Emerging Investigator issue
Profiles of the authors featured in this Environmental Science: Processes & Impacts themed issue.
Perspective
Environmental transmission of diarrheal pathogens in low and middle income countries
Globally more than half a million children die every year from diarrheal diseases. This Perspective suggests that reductions in diarrheal disease transmission in LMICs can be achieved by accounting for site-specific factors when designing environmental interventions. This is discussed in the context of the characteristics of the most important diarrheal diseases as well as environmental reservoirs.
Hardwiring microbes via direct interspecies electron transfer: mechanisms and applications
Direct interspecies electron transfer (DIET) has important implications for the design and operation of biological treatment processes.
Controls on metal exposure to aquatic organisms in urban streams
Streams in urban ecosystems receive metal inputs primarily from stormwater runoff and wastewater effluent.
Paper
Concentration dynamics of coarse and fine particulate matter at and around signalised traffic intersections
The understanding of rapidly evolving concentrations of particulate matter (PMC) at signalised traffic intersections (TIs) is limited, but it is important for accurate exposure assessment.
Chemical controls on abiotic and biotic release of geogenic arsenic from Pleistocene aquifer sediments to groundwater
Co-cycling of arsenic, manganese, iron, and dissolved organic carbon govern the extent and mode of geogenic arsenic mobilization into groundwater.
Steroidal estrogen sources in a sewage-impacted coastal ocean
Ambient estrone concentrations in Massachusetts Bay are derived largely from sources unrelated to wastewater effluent.
Wildfires and water chemistry: effect of metals associated with wood ash
The dissolution of metal-bearing carbonate and oxide phases in ash, and metal re-adsorption to ash can impact water quality after post-fire storm events.
Sticking to (first) principles: quantum molecular dynamics and Bayesian probabilistic methods to simulate aquatic pollutant absorption spectra
This work explores the relationship between theoretically predicted excitation energies and experimental molar absorption spectra as they pertain to environmental aquatic photochemistry.
Chronic exposure to triclosan sustains microbial community shifts and alters antibiotic resistance gene levels in anaerobic digesters
At environmentally relevant levels triclosan caused an increase in mexB, but had no impact on intI1.
A theoretical assessment of microplastic transport in river catchments and their retention by soils and river sediments
The presence of microplastics in soils and surface waters is a problem of growing concern.
In situ speciation of dissolved inorganic antimony in surface waters and sediment porewaters: development of a thiol-based diffusive gradients in thin films technique for SbIII
A new in situ sampling method enables the selective measurement of Sb(III) in surface waters and sediment porewaters.
Paper
The dilemma in prioritizing chemicals for environmental analysis: known versus unknown hazards
A major challenge for society is to manage the risks posed by the many chemicals continuously emitted to the environment.
Sorption selectivity of birnessite particle edges: a d-PDF analysis of Cd(II) and Pb(II) sorption by δ-MnO2 and ferrihydrite
Birnessite minerals (layer-type MnO2), which bear both internal (cation vacancies) and external (particle edges) metal sorption sites, are important sinks of contaminants in soils and sediments.
Re-analysis of narcotic critical body residue data using the equilibrium distribution concept and refined partition coefficients
An internal distribution model with relevant partition coefficients can reduce the variability of narcotic critical body residues.
Phospholipophilicity of CxHyN+ amines: chromatographic descriptors and molecular simulations for understanding partitioning into membranes
The contribution of each CHx unit to the overall membrane sorption affinity of an organic cation depends on the most favorable orientation of the sorbed molecule in the bilayer.
Occurrence and fate of nitrification and urease inhibitors in the aquatic environment
Positive findings of nitrification and urease inhibitors in the aquatic environment can occur after application in agriculture or due to industrial discharge.
About this collection
Environmental Science: Processes & Impacts is committed to supporting early career scientists, and it is because of this that we are very pleased to introduce the fourth edition of our Emerging Investigators issue, which celebrates the best and brightest among early career scientists around the world.
