Spatial distribution of smelter emission heavy metals on farmland soil (JOURNAL)
This work was conducted to explore heavy metal pollution in soils in an area near lead smelters in Jiyuan City, which is one of the main lead production areas in China. Altogether, 88 topsoil samples (0–20 cm) were collected from farmlands near the Yuguang lead smelting fac...
Influence of phosphate amendment and zinc foliar application on heavy metal accumulation in wheat and on soil extractability impacted by a lead-smelter near Jiyuan, China (JOURNAL)
Higher concentrations of Pb and Cd in wheat grains harvested in several lead-smelting-polluted areas in northern China have been reported. This field experiment was conducted to investigate the effect of phosphate amendment and Zn foliar application on the accumulation of Pb and ...
Methodological factors influencing inhalation bioaccessibility of metal(loid)s in PM2.5 using simulated lung fluid (JOURNAL)
In this study, methodological factors influencing the dissolution of metal(loid)s in simulated lung fluid (SLF) was assessed in order to develop a standardised method for the assessment of inhalation bioaccessibility in PM2.5. To achieve this aim, the effects of solid to liquid (...
The EcoService Models Library (ESML): A searchable database of ecological models for estimating the production of ecosystem goods and services (DATA)
ORD has created the EcoService Models Library (ESML) to make ecological model descriptions more available and informative. EMSL is a website and database for finding, examining and comparing ecological models that may be useful for estimating ecosystem goods and services. ESML i...
Arsenic Speciation of Contaminated Soils/Solid Wastes and Relative Oral Bioavailability in Swine and Mice (JOURNAL)
Arsenic (As) is one of the most widespread, toxic elements in the environment, and human activities have resulted in a large number of contaminated areas. However abundant, the potential of As toxicity from exposure to contaminated soils is limited to the fraction that will disso...
Assessing the Impact of Algal Organic Matter on the Performance of Biological Filtration Systems (PRESENTATION)
Most drinking water treatment processes that rely on conventional treatment methods such as coagulation/flocculation and media filtration, have proven to be unsuccessful in the removal of cyanotoxins. Thus, source water contaminated by cyanotoxins as secondary metabolites and alg...
Translating Science into Clinical Care: The Story of Air Quality and Cardiovascular Heath (PRESENTATION)
The presentation will describe the association between air pollution and risks for worsening heart and lung disease, and will describe how the EPA is partnering with CMS/CDC to provide educational materials to inform individuals at high risk from the adverse health effects of air...
Living shorelines and nitrogen mitigation on Martha's Vineyard, MA (PRESENTATION)
Increased human development along the coast and the subsequent increased delivery of excess nutrients to estuarine waterbodies can have combined deleterious effects on salt marsh ecosystems. An increasingly popular shoreline stabilization technique is the use of a living shorelin...
Green Infrastructure Monitoring at Edison Environmental Center: Permeable Pavement and Rain Garden Demonstration Site (PRESENTATION)
The Environmental Protection Agency’s Edison Environmental Center (EEC) has a research and demonstration permeable parking lot comprised of three different permeable systems: permeable asphalt, pervious concrete and permeable interlocking concrete pavers. There is also an a...
U.S. EPA National Stormwater Calculator: City of Birmingham, AL. Demonstration (PRESENTATION)
Stormwater discharges continue to cause impairment of our Nation’s waterbodies. In order to reduce impairment, EPA has developed the National Stormwater Calculator (SWC) to help support local, state, and national stormwater management objectives and regulatory efforts to re...
Comparison of two methods for the enumeration of Legionella pneumophila from potable water samples (PRESENTATION)
One-liter water samples were collected from a simulated home plumbing system in sterile polypropylene bottles containing sodium thiosulfate. A portion of each sample was analyzed using Legiolert according to the manufacturer instructions (10 ml of sample added to 90 ml of diluent...
Use of passive samplers for the detection of extra cellular algal toxins in stream mesocosms, lakes and streams (PRESENTATION)
The purpose of this study is to evaluate SPATTs and LF nsPSDs to determine their performance in determining extracellular algal toxins in both stream mesocosms and within Lake Harsha and its downstream habitats. PSDs were deployed at the end of 16 different stream mesocosms and ...
Drainage Area Characterization for Evaluating Green Infrastructure using the Storm Water Management Model (JOURNAL)
Urban stormwater runoff quantity and quality are strongly dependent upon catchment properties. Models are used to simulate the runoff characteristics, but the output from a stormwater management model is dependent on how the catchment area is subdivided and represented as spatial...
Pilot-Scale Application of Shotblast Dust for Phosphorus Removal (JOURNAL)
Phosphorus contamination is a global issue, and cost-effective remediation is sought for removing phosphorus from water. We applied a novel use of waste material called shotblast dust in a pilot-scale reactor to remove phosphorus from water. Results indicate that shotblast dust w...
Source strength functions from long-term monitoring data and spatially distributed mass discharge measurements (JOURNAL)
Source strength functions (SSF), defined as contaminant mass discharge or flux-averaged concentration from dense nonaqueous phase liquid (DNAPL) source zones as a function of time, provide a quantitative model of DNAPL source-zone behavior. Such information is useful for making ...
From Assessments to Decisions: How to Leverage Bayesian Networks (PRESENTATION)
Bayesian networks provide powerful and flexible modeling platforms for examining uncertainty and making inferences. They are especially useful for developing models that reflect causal issues such as how a stressor might impact an environmental endpoint of concern or how a decisi...
PFAS Removal Using Household Water Treatment Systems: Point-of-use (POU)/Point-of-entry (POE) - Cincinnati (PRESENTATION)
Per- and Poly- fluoroalkyl Substances (PFAS) contamination of groundwater sources in the U.S. is a widespread problem for the drinking water industry. To assist property owners and limit exposure of PFASs in residential drinking water systems, U.S. EPA conducted treatability stud...
Ecological Effects of Wildland Fire: Tradeoffs for Delivery of Ecosystem Services (PRESENTATION)
Fire is a vital process for sustained ecosystem functioning, providing habitat vitality and renewal through recolonization of new populations and succession of fire-tolerant species. Twentieth Century fire management practices have shown that removal of fire from fire-adapted eco...
A Health and Ecological Systems Framework for Vector-Borne Diseases in Puerto Rico (PRESENTATION)
Environmental, social and economic factors can influence public health, but the interactions can be difficult to understand and anticipate. A systems context, that is, a conceptual approach that simultaneously considers environmental, social and economic factors, is essential. Pr...
Evaluation of Equilibrium Passive Sampling Polymers for Monitoring Munition Constituents in Aquatic Systems. (PRESENTATION)
Objectives. A wide array of military munition constituents are present in water bodies surrounding historically deposited unexploded ordnance. A common approach for monitoring explosive constituents involves the collection of large quantities of discrete water samples combined wi...
Highlights from EPA's Wildland Fire Heath Research (PRESENTATION)
This presentation is part of the “Ecological, Human Health, Economic and Social Impacts of Wildland Fires” session. This presentation will highlight the health impacts of wildland fire smoke exposure, and the various facets of ORD’s wildland fire and health rese...
Spatial Patterns of Pharmaceuticals and Wastewater Tracers in the Hudson River Estuary (JOURNAL)
The widespread use of pharmaceuticals by human populations results in their sustained discharge to surface waters via wastewater treatment plants (WWTPs). In this study, 16 highly prescribed pharmaceuticals were quantified along a 250 km transect of the Hudson River Estuary and N...
