Using biomarkers in sewage to monitor community-wide human health: Isoprostanes as conceptual prototype

► New concept proposed for gauging the overall health of small-area human populations. ► BioSCIM uses Sewage Chemical-Information Mining to measure biomarkers in sewage. ► Real-time, low-cost assessment of community-wide heath is possible. ► Isoprostanes (biomarkers of oxidative stress) are identified as targets for BioSCIM. ► Panel of orthogonal biomarkers with complementary properties may broaden [...]

Global Conservation Maps Offer a Bird’s Eye View of Degradation

This set of interactive maps from The Nature Conservancy illustrates better than words some of the threats to environmental sustainability. Global Conservation Maps

Landscape controls on total and methyl Hg in the upper Hudson River basin, New York, USA

Approaches are needed to better predict spatial variation in riverine Hg concentrations across heterogeneous landscapes that include mountains, wetlands, and open waters. We applied multivariate linear regression to determine the landscape factors and chemical variables that best account for the spatial variation of total Hg (THg) and methyl Hg (MeHg) concentrations in 27 sub-basins across [...]

The potential for a suite of isotope and chemical markers to differentiate sources of nitrate contamination: A review

Nitrate is naturally found within the environment as part of the nitrogen cycle. However, anthropogenic inputs have greatly increased nitrate loads within ground and surface waters. This has had a severe impact on aquatic ecosystems and has given rise to health considerations in humans and livestock. Therefore, the identification of nitrate sources is important in [...]

Integrating Ecological, Carbon and Water footprint into a “Footprint Family” of indicators: Definition and role in tracking human pressure on the planet

In recent years, attempts have been made to develop an integrated Footprint approach for the assessment of the environmental impacts of production and consumption. In this paper, we provide for the first time a definition of the “Footprint Family” as a suite of indicators to track human pressure on the planet and under different angles. [...]

Himalayan Glacier-Climate Change Research Gets a Boost From China

Since the collapse of the Soviet Union, which funded glaciology to gauge central Asia’s water supply, research facilities have fallen into disuse or disrepair. Tajikistan, for instance, lost many of its stations—along with the scientists who staffed them—during its bloody 1992–97 civil war. But the outlook is improving, thanks to a new commitment to regional [...]

Book Baselines Climate Change’s Effects on the Adirondacks

Jerry Jenkins, who is the author of the book “Climate Change in the Adirondacks: The Path to Sustainability,” spends much of his time on the water and in the woods, documenting the ecosystem with a notebook and a camera. He thus brings an unusual perspective to the scene. Where a casual observer might behold diversity [...]
