Governments worldwide do not adequately protect their limited freshwater systems and therefore place freshwater functions and attendant ecosystem services at risk. The best available scientific evidence compels enhanced protections for freshwater systems, especially for impermane...

We propose a modified eco-efficiency (EE) framework and novel sustainability analysis methodology for green infrastructure (GI) practices used in water resource management. Green infrastructure practices such as rainwater harvesting (RWH), rain gardens, porous pavements, and gree...

We evaluated the current literature, coupled with our collective research expertise, on surface-water connectivity of wetlands considered to be "geographically isolated" (sensu Tiner Wetlands 23:494-516, 2003a) to critically assess the scientific foundation of grouping wetlands b...

In traditional watershed delineation and topographic modeling, surface depressions are generally treated as spurious features and simply removed from a digital elevation model (DEM) to enforce flow continuity of water across the topographic surface to the watershed outlets. In re...

Wetland depressions without surface channel connections to aquatic systems are substantial sinks for nitrogen (N), phosphorus (P), and organic carbon (org. C). We assessed accretion, N, P, and org. C accumulation rates in 43 depressional wetlands across three ecoregions of the U....

We demonstrate a novel, spatially explicit assessment of the current condition of aquatic ecosystem services, with limited sensitivity analysis for the atmospheric contaminant mercury. The Integrated Ecological Modeling System (IEMS) forecasts water quality and quantity, habitat ...

The purpose of this paper is to 1) highlight projects collecting large volumes of unique air quality data; 2) explore how the collection of big data fits into the overall picture of air quality management and characterization; 3) provide an update on the E-Enterprise advanced mon...

There currently are a wide variety of approaches emerging to adjust air sensor data, either on the device or more commonly, on a manufacturer's server or cloud. The goal of these adjustments are to correct for measurement artifacts and produce more accurate values. However, most ...

During May 2016 a very large boreal wildfire burned throughout the Athabasca Oil Sands Region (AOSR) in central Canada, and in close proximity to an extensive air quality monitoring network. This study examines speciated 24-h integrated polycyclic aromatic hydrocarbon (PAH) and v...

The increasing emission of primary and gaseous precursors of secondarily formed atmospheric particulate matter due to continuing industrial development and urbanization are leading to an increased public awareness of environmental issues and human health risks in China. As part o...

The production of photochemical atmospheres under controlled conditions in an irradiated chamber permits the manipulation of a variety of parameters that influences resulting air pollutant chemistry and potential biological effects. To date no studies have examined how contrastin...

Select volatile organic compounds (VOCs) in ambient air were measured at four fenceline sites at a petroleum refinery in Whiting, Indiana, USA using modified EPA Method 325 A/B with passive tubes and EPA Compendium Method TO-15 with canister samplers. One-week, time-integrated s...

The probability density function (PDF) of the time intervals between subsequent extreme events in atmospheric Hg0 concentration data series from different latitudes has been investigated. The Hg0 dynamic possesses a long-term memory autocorrelation function. Above a fixed thresh...

Several low-volume inlets (flow rates ≤ 16.7 liters per minute (Lpm)) are commercially available as components of low-cost, portable ambient particulate matter samplers. Because the inlets themselves do not contain internal fractionators, they are often assumed to representativel...

An unprecedented wildfire impacted the northern Alberta city of Fort McMurray in May 2016 causing a mandatory city wide evacuation and the loss of 2,400 homes and commercial structures. A comprehensive air monitoring network operated by the Wood Buffalo Environmental Association ...

Traditionally, gas chromatography – mass spectrometry (GC-MS) analysis has used a targeted approach called selected ion monitoring (SIM) to quantify specific compounds that may have adverse health effects. Due to method limitations and the constraints of preparing duplicate samp...

In May 2017, a two-day workshop was held in Los Angeles (California, U.S.A.) to gather practitioners who work with low-cost sensors used to make air quality measurements. The community of practice included individuals from academia, industry, non-profit groups, community-based or...

Although many volatile organic compounds (VOCs) are regulated to limit air pollution and the consequent health effects, the photooxidation products generally are not. Thus, we examined the mutagenicity in Salmonella TA100 of photochemical atmospheres generated in a steady-state a...

The data contained in this article are PubMed search strings and search string builders used to curate breath research manuscripts published from 1995–2016 and the respective number of articles found that satisfied the search requirements for selected categories. Breath sampling ...

There is high demand in environmental health for adoption of a structured process that evaluates and integrates evidence while making decisions transparent. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework holds promise to address this deman...

Introduction: Host resistance assays, the gold standard of immunotoxicity testing, are a powerful approach to evaluate global functional capacity in a fully interactive immune system. Host resistance assays based on the clearance of a replicating infectious agent provide a critic...

Modern urban life style is associated with chronic stress, insufficient physical activity and exposure to anthropogenic environmental hazards. Urban green space, such as parks, playgrounds, and residential greenery, can promote mental and physical health and reduce morbidity and ...

Allergic contact dermatitis (ACD) continues to be an occupational and environmental health issue.&nbsp; Consequently, there is a need to employ predictive tests to reduce the incidence of skin sensitization leading to clinical manifestations of ACD.&nbsp;&nbsp; For more than a de...

Allergic diseases (atopy) include asthma, allergic rhinitis, conjunctivitis, and allergic sinusitis. It is estimated that up to 90% of asthmatics are atopic and have an allergy trigger for asthmatic episodes. In order to assess the risk of allergy induction associated with inhala...

Stress tests are used clinically to uncover underlying disease and predict future cardiovascular risk. Previously, we used treadmill exercise stress in rats to reveal latent effects of air pollution inhalation. Other daily stressors, when modeled experimentally, may have similar ...
