EDITORS NOTE: This paper represents 1 of 6 papers in the special series "Passive Sampling Methods for Contaminated Sediments," which was generated from the SETAC Technical Workshop "Guidance on Passive Sampling Methods to Improve Management of Contaminated Sediments," held November 2012 in Costa Mesa, California, USA. Recent advances in passive sampling methods (PSMs) offer an improvement in risk-based decision making, since bioavailability of sediment contaminants can be directly quantified. Forty-five experts, representing PSM developers, users, and decision makers from academia, government, and industry, convened to review the state of science to gain consensus on PSM applications in assessing and supporting management actions on contaminated sediments. ...
Aerosol dry deposition is not much known for urban areas due to the lack of data. Knowledge on this phenomenon is necessary to understand pollutant fluxes in cities and to estimate inhabitant exposition to ionizing radiation of radioactive aerosols. A data providing could enable to enhance dry deposition models for these areas. An original experimental approach is performed to study submicron aerosol dry deposition on urban surfaces. Wind tunnel coupled to in situ experiments give results to study different physical phenomenon governing dry deposition. Dry deposition velocities are measured using aerosol tracers. These data are associated to turbulent and meteorological measured conditions. This database permits to classify the principal physical phenomenon for each experiment type. Finally, different phenomenon must be considered for chronic and acute exposition of urban surfaces to atmospheric particles. ...

Field Tests Detection limits: Because the intent of the passive sampling device is for use in the museum environment where the concentration of pollutants may be low, it is necessary to insure that a potential passive sampling device (PSD) is effective at the desired level, in the range from 5 ppb to 800 ppb for formaldehyde. Reproducibility: Reproducibility is confirmed to establish the validity of using a limited number of PSDs (frequently only one) at a particular location. Percent Recovery: The amount of analyte recovered when the passive sampler is exposed to a known amount of pollutant is also determined. The badge is spiked with a known amount of analyte, and it is confirmed that the analyte is recovered during the analytical process. This is a measure of the analytical method. Comparison with Active Sampling: The passive sampling device is also compared with a standardized active sampling method to further validate its use. Interference Studies: The badges response to the target ...
China - Nanchang Urban Rail Project : environmental assessment (Vol. 5) : Environmental and social management plan (Английский)
Studying environmental quality is a challenging task. It is a complicated exercise since the environment is constantly influenced by numerous variables such as climate change, anthropogenic activities, and unexpected natural disasters. Traditionally, exposure to chemical pollutants depended on chemical and physical analysis of environmental media. Unfortunately, this approach has not taken into consideration bioavailability of the chemical(s) of interest to exposed organisms and/or modification of the chemical (bioactivation/detoxification) by the organism. Benthic macroinvertebrates (BMIs) have been chosen as bioindicators for numerous environmental biomonitoring programs geared towards the assessment of aquatic ecosystems. Biomonitoring requires a more subtle measure - a biomarker - which should be dependable, reliable, and specific for assessing various ecological issues and human health risks. A wide array of biomarkers has focused on sublethal changes at the cellular and molecular levels. Good

Our results show that emissions from natural sources were particularly abundant in summer, and with a more pronounced influence at the rural compared to the urban background site. 80% of total carbon (TCp, corrected for the positive artefact) in PM10 and ca. 70% of TCpin PM1 could be attributed to natural sources at the rural background site in summer. Natural sources account for about 50% of TCp in PM10 at the urban background site as well. The natural source contribution was always dominated by OCBSOA, regardless of season, site and size fraction. During winter anthropogenic sources totally dominated the carbonaceous aerosol (80-90%). Combustion of biomass contributed slightly more than fossil-fuel sources in winter, whereas emissions from fossil-fuel sources were more abundant in summer ...

The tiered model, however, does not preclude the requirement for iterations within each tier where necessary. Iteration is an unprescribed re-evaluation of information that may occur at any time during a risk assessment done in response to an identified need, new information or questions raised during an assessment. As such iteration is a normal characteristic of risk assessments but is not a formal planned step (USEPA 1998). An example of an iteration may be returning to sample uncontaminated land surrounding the site in order to answer questions about background concentrations of contaminants.. While using a tiered RA model may reduce the need for iteration, it is not intended to eliminate it entirely, as iteration is an essential method of identifying and obtaining the information required.. It is important to note that by proceeding from Tier 1 to Tiers 2 and 3, there is a decreasing degree of conservatism and an increasing degree of certainty that the values reached approximate the true ...

Abstract: Measuring human exposures to ambient air pollutants is challenging, particularly in large epidemiologic studies in which direct monitoring is not feasible. Thus, several exposure estimation methods, including land use regression and Kriging, have been developed to estimate individual exposures within urban areas. A major limitation of these methods is their use of residential address to estimate exposures. Because of the variation in air pollutant concentrations within an urban area, a residential exposure may differ substantially from exposures experienced while away from home.. We are developing an innovative, feasible and cost-effective method to measure time-activity data, i.e. human movement over time, and incorporate these data into current residence-based methods of air pollutant exposure estimation. We will use cellphones equipped with global positioning system (GPS) to measure the daily movements of 40 cellphone-using volunteers in western New York for a period of three ...
In preparation for a study of the relative oral bioavailability of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) in soils (typically containing less than 1 ppb 2,3,7,8-tetrachlorodibenzo-p-dioxin [TCDD] toxic equivalents [TEQ]), the background concentrations of PCDD/ Fs and selected polychlorinated biphenyls (PCBs) were measured in liver and adipose tissue from female Sprague-Dawley rats and juvenile swine after 30 d of ingesting laboratory chow. The measured concentrations of TCDD and other PCDD/Fs in rat livers were severalfold less than previously reported in the literature for control (unexposed) laboratory rodents. The concentrations of PCDD/Fs and selected PCBs in livers of swine were three- to fourfold lower than those reported for rats. The lower concentrations found in this study compared to previous findings may be due to inadvertent laboratory contamination in previous studies or to declining levels of PCDD/Fs in laboratory feed, which parallel the declines in ...

Environmental Assessment for NSLS-II Released

October 13, 2006

In accordance with the National Environmental Policy Act (NEPA), the Department of Energy (DOE) has prepared an Environmental Assessment of the proposed National Synchrotron Light Source II (NSLS-II). This evaluation of the construction and operation of the proposed facility found that there would be no significant impact. The EA analyzed the potential environmental consequences of the
Introduction. The common approach in risk assessment of water bodies is to collect a sample of the water, which is then analysed for potential pollutants in the laboratory. This approach, among other advantages, provides manageable control over accuracy and precision of the results. However, information obtained from spot water samples is only about concentration levels at the time of sampling and may fail to account for episodic contamination. This can be addressed by collecting a series of samples over a time period to obtain a more representative picture of water quality, but the cost of analysis is then increased. An alternative and more cost-effective approach is to obtain time-weighted average (TWA) concentrations of pollutants using passive samplers. Passive samplers are now seen as an alternative to conventional spot samples. This is seen by a number of recent reviews on passive samplers (Vrana et al., 2005; Lu et al., 2002; Petty et al., 2000; Stuer-Lauridsen, 2005; Chimuka and ...
Pesticide exposure estimation in epidemiologic studies can be constrained to analysis scales commonly available for cancer data-census tracts and ZIP codes. Research goals included (1) demonstrating the feasibility of modifying an existing geographic information system (GIS) pesticide exposure method using California Pesticide Use Reports (PURs) and land use surveys to incorporate Landsat remote sensing and to accommodate aggregated analysis scales, and (2) assessing the accuracy of two rurality metrics (quality of geographic area being rural), Rural-Urban Commuting Area (RUCA) codes and the U.S. Census Bureau urban-rural system, as surrogates for pesticide exposure when compared to the GIS gold standard. Segments, derived from 1985 Landsat NDVI images, were classified using a crop signature library (CSL) created from 1990 Landsat NDVI images via a sum of squared differences (SSD) measure. Organochlorine, organophosphate, and carbamate Kern County PUR applications (1974‐1990) were matched to ...

A bioindicator is any species (an "indicator species") or group of species whose function, population, or status can reveal the qualitative status of the environment. For example, copepods and other small water crustaceans that are present in many water bodies can be monitored for changes (biochemical, physiological, or behavioural) that may indicate a problem within their ecosystem. Bioindicators can tell us about the cumulative effects of different pollutants in the ecosystem and about how long a problem may have been present, which physical and chemical testing cannot. A biological monitor, or biomonitor, can be defined as an organism that provides quantitative information on the quality of the environment around it. Therefore, a good biomonitor will indicate the presence of the pollutant and also attempt to provide additional information about the amount and intensity of the exposure. A biological indicator is also the name given to a process for assessing the sterility of an environment ...

Particles released to the atmosphere from anthropogenic sources affect the Earths climate as well as the health of the population. Anthropogenic sources of atmospheric particles are e.g. the combustion of biomass and fossil fuels, road, brake and tire wear and various industrial activities. There is great interest to find the importance of different sources to the particle concentrations in the atmosphere to minimize their impact on climate and health. This work investigates how well particle sources are assessed when using source-receptor models. The main focus of this work lies in retrieving the uncertainties and difficulties of using these models on sampled particulate data. Comparison is made with other methods, e.g. a meteorological air pollution dispersion model and a tracer method.. Depending on the source origin, the uncertainties of the source profiles are different and require different approaches to be quantified. Conclusions drawn from this thesis are:. • assessment of ...

In order to determine the impact of aerosol pollution on ecosystems and buildings, the transfer functions of particles onto vegetation or buildings must first be studied. According to the meteorological conditions, the aerosol deposit may be considered as wet or dry. This dry deposition, characterized by a dry deposition velocity, depends on numerous parameters, such as for example, the topography of the land, the substrate, the micrometeorological conditions (turbulence) and the size distribution of the aerosols. The study of dry aerosol deposition remains an area of research which is still open and which necessitates an experimental approach in situ to take into account the local characteristics (turbulence, substrate, vegetation, etc ...

The strategic environmental assessment (SEA) is carried out for certain plans, programmes that are likely to have significant environmental effects in accordance with the SEA Act (200/2005) and the SEA Decree (347/2005). The purpose of SEA is to ensure that environmental considerations are integrated into plan and programme in support of environmentally sound and sustainable development. Environmental assessment means an assessment of the environmental effects of a plan or programme and its alternatives, preparation of an environmental report, carrying out consultations, taking into account the environmental report and the results of consultations in decisionmaking, and the provision of information on the decision. The SEA is made by the authority preparing the plan or programme. The types of plans and programmes subject to the SEA are mainly specified in the legislation. A SEA is a required for e.g. national land use objectives, nature conservation programmes, regional plans, river basin ...
Human activity can increase the fluxes from some of these natural sources. For example, poor agricultural practices can lead to large-scale loss of soil by Wind erosion. There are also purely anthropogenic sources of suspended particulates. Particularly important in this regard is the burning of fossil fuels and biomass. Particulates generated by combustion are mainly fine. These settle much more slowly than the coarse particulates and therefore tend to reside in the atmosphere for longer. In general, they are removed by wet deposition or, if brought into contact with surfaces by situ within the atmosphere. For example, the aerial oxidation of sulfur dioxide produces significant quantities of sulphate particles ...

Turning to adverse effects of plastic on the human population, there is a growing body of literature on potential health risks. A range of chemicals that are used in the manufacture of plastics are known to be toxic. Biomonitoring (e.g. measuring concentration of environmental contaminants in human tissue) provides an integrated measure of an organisms exposure to contaminants from multiple sources. This approach has shown that chemicals used in the manufacture of plastics are present in the human population, and studies using laboratory animals as model organisms indicate potential adverse health effects of these chemicals (Talsness et al. 2009). Body burdens of chemicals that are used in plastic manufacture have also been correlated with adverse effects in the human population, including reproductive abnormalities (e.g. Swan et al. 2005; Swan 2008; Lang et al. 2008).. Interpreting biomonitoring data is complex, and a key task is to set information into perspective with dose levels that are ...
Cancer cluster is a term used to describe any increase in the number of cancer cases over what would be expected in a particular area during a specific period of time. Cancer actually occurs in clusters quite often. Although the tendency is to blame this type of clustering on pollutants in the air, water or soil, a variety of factors unrelated to the environment are often responsible.. Clusters are frequently a matter of statistical chance not unlike what happens at a roulette wheel. If you play long enough, red is bound to come up six times in a row. The unusual run of one color doesn t necessarily mean the wheel is unbalanced or that the house is cheating. Statistically, this type of run is expected to happen every now and again. Stick around long enough and you ll probably see an equally long run of blacks.. The same is true of cancer. Although it s highly unlikely that several men living on the same block would all develop prostate cancer within a relatively short period of time, it can and ...

It is well established that our nations health-based standards are the very bedrock of our nations clean air laws - saving lives and empowering communities with critical air quality information.. What is standing in the way of saving lives and ensuring healthier air for our families and children? A well-funded "sky is falling" campaign by polluters and other naysayers. These big emitters claim that our nation cannot afford protective smog standards. These opponents also attack the science that shows the need for a stronger smog standard, in direct opposition to the more than one thousand peer-reviewed studies that EPA considered while working on updating the health-based standard..

The sediment to water diffusive flux of PAHs and PCBs was measured under field conditions with a novel infinite-sink benthic flux chamber that deployed semipermeable membrane devices (SPMD) as a sorbing material. Fluxes were measured before and after in situ capping of sediments in Oslo Harbour with clean clay. The fluxes of native pyrene and PCB 52 from uncapped contaminated sediment measured with the flux chamber were 0.3-1.6 mu g m(-2) d(-1) and 2-8 ng m(-2) d(-1), respectively. Fluxes from the capped sediment were reduced by 93-97%. The in situ measured fluxes were compared to fluxes independently calculated from freely dissolved concentrations in pore water and overlying water, measured using equilibrium passive samplers, diffusive boundary layer (DBL) thickness, measured by an alabaster dissolution method and literature values of diffusion coefficients. Measured fluxes from the uncapped sediment agreed well with calculated fluxes, the median of the ratio of the measured flux over the ...

Environmental Public Health Tracking is the ongoing collection, integration, analysis, interpretation, and dissemination of data on environmental hazards, exposures to those hazards, and related health effects. The goal of tracking is to provide information that can be used to plan, apply, and evaluate actions to prevent and control environmentally related diseases. In many cases, however, data are not available on what substances are getting into people and at what levels (exposure data).. Biomonitoring-the direct measurement of chemicals in human specimens such as blood or urine-is a powerful tool essential for closing the gaps in exposure data. CDC and its partners, including the Association of Public Health Laboratories (APHL), are supporting state and local agencies in building their tracking and biomonitoring capacity. ...

There was one key toxicokinetic study identified which evaluated the absorption and distribution of linear alpha olefins, oct-1-ene, non-1-ene, and dec-1-ene, and the corresponding C8, C9, and C10 isoalkanes in rats (Zahlsen, 1993). Male Sprague-Dawley rats (16/dose) were exposed via whole body inhalation to 100 ppm vapour of the individual test substances for 12 hours/day for 3 consecutive days. Concentrations of the hydrocarbons were measured in blood, brain, liver, kidney and perirenal fat immediately following each 12 hour exposure and 12 hours following the last exposure. Higher concentrations of linear alpha olefins were measured in each of the respective organs compared with measured concentrations of the corresponding isoalkanes, with the highest concentrations measured in fat. All measured concentrations of linear alpha olefins and isoalkenes were significantly decreased following the 12 hour recovery period; however the largest residual accumulations were measured in the fat. With the ...

One of McIntyres repeated complaints about Briffa was that he refused to release his data. For example, in his post Fresh Data on Briffas Yamal #1: A few days ago, I became aware that the long-sought Yamal measurement data url had materialized at Briffas website - after many years of effort on my part and nearly 10 years after its original use in Briffa (2000).
EPA, in keeping with the administrations focus to ensure that the agency leverages domestic resources safely and responsibly, announced the next steps in its congressionally mandated hydraulic fracturing study.
A limitation of Sargas technology is that the system works under pressure and only a handful of coal-fired power plants so far use the so-called Pressurised Fluidised Bed Combustion technology -- in Sweden, Japan and Germany.. That means it can be used in new plants, including any burning natural gas, but cannot be easily retro-fitted at plants where exhaust gases come out at atmospheric pressure.. Its not a big technology for existing plants but for future plants it could be interesting ... theoretically you dont need so much energy, said Eva-Katrin Lindman, head of research and development at Fortum Varme.. Among other projects, WE Energy and Alstom Power Inc plan to start a test carbon capture facility at the Pleasant Prairie coal-fired plant in Wisconsin by the end of the year, using a system using chilled ammonia.. Sargas is working with aluminum producers Alcan and Norsk Hydro, French metals producer Eramet and Norwegian group Tinfos on plans to build a coal-fired power plant to ...
TY - JOUR. T1 - Aquatic environmental assessment of Lake Balaton in the light of physical-chemical water parameters. AU - Sebestyén, Vitkor. AU - Németh, József. AU - Juzsakova, Tatjana. AU - Domokos, Endre. AU - Kovács, Zsófia. AU - Rédey, A.. PY - 2017/11/1. Y1 - 2017/11/1. N2 - One of the issues of the Hungarian Water Management Strategy is the improvement and upgrading of the water of Lake Balaton. The Water Framework Directive (WFD) specifies and sets forth the achievement of the good ecological status. However, the assessment of the water quality of the lake as a complex system requires a comprehensive monitoring and evaluation procedure. Measurements were carried out around the Lake Balaton at ten different locations/sites and 13 physical-chemical parameters were monitored at each measurement site. For the interpretation of the water chemistry parameters the Aquatic Environmental Assessment (AEA) method devised by authors was used for the water body of the Lake Balaton. The AEA ...
Human exposure to air pollution in many studies is represented by ambient concentrations from space-time kriging of observed values. Space-time kriging techniques based on a limited number of ambient monitors may fail to capture the concentration from local sources. Further, because people spend more time indoors, using ambient concentration to represent exposure may cause error. To quantify the associated exposure error, we computed a series of six different hourly-based exposure metrics at 16,095 Census blocks of three Counties in North Carolina for CO, NOx, PM2.5, and elemental carbon (EC) during 2012. These metrics include ambient background concentration from space-time ordinary kriging (STOK), ambient on-road concentration from the Research LINE source dispersion model (R-LINE), a hybrid concentration combining STOK and R-LINE, and their associated indoor concentrations from an indoor infiltration mass balance model. Using a hybrid-based indoor concentration as the standard, the comparison showed
In 2005, the province of Ontario began a process that would eventually lead to the phasing out of its coal-fired power plants, the largest of which were the Lambton and Nanticoke facilities in southern Ontario. The rationale for shuttering these plants was a 2005 cost-benefit analysis that assumed that about $3 billion in annual savings to the health care system would come from the reduction of smog-related air contaminants. However, that analysis, and another one done for the province the same year on the effects of cross-border air pollution, reported that the phase-out of coal would have only very modest effects on Ontario air quality, which is consistent with emissions inventory data showing that electric power generation was a minor contributor to particulate and ozone pollution at the time. The cost savings estimate came from assuming very large health effects associated with very small changes in air pollution.. In the aftermath of the coal phase-out, and the extremely costly changes to ...

Like most other steam-producing electricity plants, coal units typically withdraw and consume water from nearby water bodies such as lakes, rivers or oceans, to create steam for turning their turbines.. The Union of Concerned Scientists (UCS) reports that a typical coal-fired power plant employing a once-through cooling system withdraws 70−180 billion gallons of water every year and consumes 0.36-1.1 billion gallons of it. A coal plant with a wet-recirculating cooling system extracts only a fraction of that figure, but still consumes 1.7−4.0 billion gallons a year, while a dry-cooled system uses much less.. Around 53% of US coal plants use once-through cooling and 40% wet-recirculating systems. The US Environmental Protection Agency (EPA) estimates that dry-cooling facilities produce around 7% less power than wet-recirculating plants; hence, under 1% of units use this technology.. Water also plays a pivotal role in coal mining and transportation. In addition to burying streams, contaminating ...
