Background: A carbon footprint is the sum of greenhouse gas emissions (GHGEs) associated with food production, processing, transporting, and retailing.
Understanding the Links Between Human Health and Climate Change: Agricultural Productivity and Allergenic Pollen Production of Timothy Grass(Phleum pratense L.) Under Future Predicted Levels of Carbon Dioxide and Ozone
Carbon Dioxide Climate Change Grass Pollen Human Health Ozone Phleum pratense
2014/11/4
The prevalence of allergic disease is expected to increase with climate change. Grasses, which have highly allergenic pollen, are widely distributed across the globe. Changes in production and allerge...
Geochemistry and Inorganic Carbon Transport of a Glacial Till Drumlin at a Road Salt Facility
road salt total dissolved inorganic carbon transport

Investigations were conducted at a salt/premix storage facility lying on top of a glacial drumlin near the coastline in eastern Massachusetts, to characterize salt contaminated groundwater. Groundwate...
A Paleoclimate Modeling Experiment to Calculate the Soil Carbon Respiration Flux for the Paleocene-Eocene Thermal Maximum
A Paleoclimate Modeling Experiment Calculate the Soil Carbon Respiration Flux the Paleocene-Eocene Thermal Maximum
2014/10/21
The Paleocene-Eocene Thermal Maximum (PETM) (55 million years ago) stands as the largest in a series of extreme warming (hyperthermal) climatic events, which are analogous to the modern day increase i...
Regional-scale variation of dissolved organic carbon concentrations in Swedish lakes
Organic carbon lakes
2014/10/16
We assessed spatial variability in dissolved organic carbon (DOC) concentrations measured in nearly 2000
Swedish lakes. Inter-lake variance peaked at two different scales, representing within-region ...
Identifying variable sea ice carbon contributions to the Arctic ecosystem: A case study using highly branched isoprenoid lipid biomarkers in Cumberland Sound ringed seals
Sea ice carbon The arctic ecosystem
2014/10/16
We analyzed liver samples from 322 ringed seals (Pusa hispida) collected from Cumberland Sound (southeast
Baffin Island) to test our ability to differentiate between carbon sources in near apex preda...
Effects of carbon nanotubes on airway epithelial cells and model lipid bilayers : proteomic and biophysical studies
Carbon Nanotube Calu-3 cells DPhPC lipid bilayer
2015/5/22
Carbon nanomaterials are widely produced and used in industry, medicine and scientific research. To examine the impact of exposure to nanoparticles on human health, the human airway epithelial cell li...
A University of Arizona-led team of physicists has discovered how to change the crystal structure of graphene, more commonly known as pencil lead, with an electric field, an important step toward the ...

2017/4/11
Dissolved organic carbon (DOC) can be considered fine indicators of soil quality that influence soil function in specific
ways and are very sensitive to changes in soil management practices. In this ...
Carbon isotope variations in diploptene for methane hydrate dissociation during the last glacial episode in the Japan Sea/East Sea
diploptene methane hydrate dissociation carbon isotope glacial–interglacial sea-level changes
