Ключевые слова: environmental monitoring; pollutants; toxicity; creeping fire; high-grade pine stands; bioindicators , HORMESIS Аннотация: Five permanent sample plots (SPs; 200-250 trees per plot) were established in middle-aged high-grade suburban pine stands near the industrial city of Krasnoyarsk, Siberia, Russia. Needle damage, inventory parameters of the stands, and the defense response of the stem phloem were evaluated annually for the years 2002-2019 and attribПоказать полностьюuted to acute or chronic toxic exposures (creeping fire or industrial pollutants, respectively). The results form a basis for using trees as bioindicators. A newly elaborated stem lesion test was formed from a hypothesis on the upward sugar transport for the regeneration of an injured crown, based on Eschrichs model of bidirectional sugar transport in the phloem. The formation of a ...
HBM4EU will use Human Biomonitoring to assess human exposure to chemicals in Europe, to better understand the associated health impacts and to improve chemical risk assessment. Despite the existence of human biomonitoring programmes at national level and the large number of research and development projects ongoing both at national and European Union level, there is a clear lack of data on aggregate exposure to single substances and to combinations of chemical substances, as well as insufficient evidence-based knowledge on the link between external exposure via different routes, internal levels and human health. This knowledge is essential to inform effective policy-making to protect the European population from the impacts of chemical exposure on health. HBM4EU will form a bridge between science and policy. Our research will explore current questions in chemical risk assessment and management and will deliver answers that help policy makers to protect human health. Policy makers, stakeholders ...

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. ...

Seabirds are those waterbirds that directly or indirectly depend on the marine environment over the waters, i.e., they foraged at sea either near shore or offshore and inhabit in coastal areas, islands, estuaries, wetlands, and ocean islands. They are mostly aerial waterbirds sailing above sea spending much of their time (weeks, months, and even years) in marine environments or floating on the water surface or diving in deep sea in search of food. Seabirds encompass of 65 genera, 222 marine, and 72 partially marine bird species. Seabirds have been used as good indicators (i.e., bioindicators) of marine ecosystems due to cause-effect association with different microclimate and habitats. They exploit broad scale of habitat, quickly respond to environmental changes, they can be detected easily (i.e., they showed their presence through vocalization), easy to identify, can be surveyed efficiently over large spatial scale, e.g., presence, abundance, and influenced by surrounding habitats as compared to other

Key decisions in the design of biomonitoring programs include taxonomic resolution, geographic extent, and site selection, each of which can affect our ability to infer human impacts on biodiversity from biomonitoring data. These decisions are constrained by monitoring goals and budget limitations, which may require trade-offs between them. In this study, we use species distribution models (SDMs) to assess the effects of key decisions in biomonitoring design on our ability to infer the effects of natural and anthropogenic environmental conditions on the occurrence of benthic macroinvertebrates in streams. We compared 4 datasets that differ in their site-selection strategy, geographic extent, and taxonomic resolution using data from Swiss federal and cantonal biomonitoring programs. We used individual SDMs with 3-fold cross validation to identify the environmental variables that best predict the probability of taxa occurrence across the datasets. We then used a hierarchical multi-species ...
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 ...
Evaluation of the adverse health effects of PM10 pollution (particulate matter less than 10 microns in diameter) is very important for protecting human health and establishing pollution control policy. Population exposure estimation is the first step in formulating exposure data for quantitative assessment of harmful PM10 pollution. In this paper, we estimate PM10 concentration using a spatial interpolation method on a grid with a spatial resolution 0.01° × 0.01°. PM10 concentration data from monitoring stations are spatially interpolated, based on accurate population data in 2000 using a geographic information system. Then, an interpolated population layer is overlaid with an interpolated PM10 concentration layer, and population exposure levels are calculated. Combined with the exposure-response function between PM10 and health endpoints, economic costs of the adverse health effects of PM10 pollution are analyzed. The results indicate that the population in Lanzhou urban areas is distributed in a

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
Strategic Environmental Assessment (SEA) is the formal, systematic evaluation of the likely significant environmental effects of implementing a plan or programme before the decision is made to adopt the plan or programme.

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 ...

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 ...
TY - JOUR. T1 - Analysis of Health in Environmental Assessments. T2 - A Literature Review and Survey with a Focus on Denmark. AU - Humboldt-Dachroeden, Sarah. AU - Fischer-Bonde, Birgitte. AU - Gulis, Gabriel. PY - 2019/11/18. Y1 - 2019/11/18. N2 - In the European Union, the Environmental Impact Assessment (EIA) Directive (2014/52/EU) and Strategic Environmental Assessment (SEA) Directive (2011/92/EU) emphasise the assessment of population and human health. The directives require health to be considered within Environmental Impact Assessment (EIA) and Strategic Environmental Assessment (SEA). To date, health is mainly considered in connection with negative environmental factors and in terms of risk assessments. The integration of health in EIA as well as SEA has not been investigated in a Danish context, and this study aims to address the missing knowledge. There is a need for a more comprehensive health assessment within EIA and SEA to comply with the EIA and SEA directives. An integration of ...
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 ...
Title: Lichen bioindicators of nitrogen and sulfur deposition in dry forests of Utah and New Mexico, USA. Authors: Root, Heather T.; Jovan, Sarah; Fenn, Mark; Amacher, Michael; Hall, Josh; Shaw, John D.. Date: 2021. Source Ecological Indicators. 127: 107727.. Abstract: Anthropogenic nitrogen (N) and sulfur (S) deposition can negatively affect ecosystem functions and lichen biomonitors can be a cost-effective way to monitor air pollution exposure across the landscape. Interior dry forests of the southwestern United States face increasing development pressures; however, this region differs from others with well-developed biomonitoring programs in having drier climates and a greater fraction of deposition delivered in dry forms. We measured throughfall N and S deposition at 12 sites in Utah and 10 in New Mexico and co-located collection of 6 lichen species. Throughfall N deposition ranged from 0.76 to 6.96 kg/ha/ year and S deposition from 0.57 to 1.44 kg/ha/year with elevated levels near human ...

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 ...

Using human health risk assessment(HRA) procedures to determine the remediation or redevelopment of contaminated site has become a new research area.In the paper,based on the future land use patterns,the HRA model was applied to evaluate the health risk brought by PAHs contamination in a site for redevelopment.The results indicated that under the two exposure scenarios including the normal condition and the extreme condition,and three exposures,including inhalation exposures,dermal exposures and ingestion exposures,the carcinogenic risk brought by PAHs contamination was comparatively high,and exceed the acceptable health risk lever in several sites.Take the sensitive children for example,the risk-based PAHs remedial goal of 634 μg/kg was calculated for reducing the carcinogenic risk to acceptable level under the extreme condition.In future,with the development of environmental management,the HRA should be strengthening during urban land redevelopment.

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 ...

TY - JOUR. T1 - Fiducial generalized p-values for testing zero-variance components in linear mixed-effects models. AU - Li, Xinmin. AU - Su, Haiyan. AU - Liang, Hua. PY - 2018/7/1. Y1 - 2018/7/1. N2 - Linear mixed-effects models are widely used in analysis of longitudinal data. However, testing for zero-variance components of random effects has not been well resolved in statistical literature, although some likelihood-based procedures have been proposed and studied. In this article, we propose a generalized p-value based method in coupling with fiducial inference to tackle this problem. The proposed method is also applied to test linearity of the nonparametric functions in additive models. We provide theoretical justifications and develop an implementation algorithm for the proposed method. We evaluate its finite-sample performance and compare it with that of the restricted likelihood ratio test via simulation experiments. We illustrate the proposed approach using an application from a ...
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 ...
Monitoring of nutrients including phosphate in the aquatic environment remains a challenge. In the last decade passive sampling techniques have been developed that facilitates the time integrated monitoring of phosphate (P) through the use of an iron hydroxide (ferrihydrite) to sequester dissolved phosphate from solution. These methods rely on established techniques to negate the effects of flow (and associated turbulence) and control the rate at which chemicals accumulate within passive samplers. In this study we present a phosphate sampler within which a suspension of ferrihydrite is contained behind a commercially available membrane. Accumulation of dissolved phosphates into the P-sampler is governed by the rate at which ions are diffusing through the membrane and the water boundary layer (WBL). As the WBL changes subject to flow we have adopted an in situ calibration technique based on the dissolution of gypsum to predict the change in the rate of uptake dependent on flow. Here we ...
In the event of an indoor release of an environmentally persistent microbial pathogen such as Bacillus anthracis, the potential for human exposure will be considered when remedial decisions are made. Microbial site characterization and clearance sampling data collected in the field might be used to estimate exposure. However, there are many challenges associated with estimating environmental concentrations of B. anthracis or other spore-forming organisms after such an event before being able to estimate exposure. These challenges include: (1) collecting environmental field samples that are adequate for the intended purpose, (2) conducting laboratory analyses and selecting the reporting format needed for the laboratory data, and (3) analyzing and interpreting the data using appropriate statistical techniques. This paper summarizes some key challenges faced in collecting, analyzing, and interpreting microbial field data from a contaminated site. Although the paper was written with considerations ...

The use of Linear Mixed-effects Models (LMMs) is set to dominate statistical analyses in psychological science and may become the default approach to analyzing quantitative data. The rapid growth in adoption of LMMs has been matched by a proliferation of differences in practice. Unless this diversity is recognized, and checked, the field shall reap enormous difficulties in the future when attempts are made to consolidate or synthesize research findings. Here we examine this diversity using two methods - a survey of researchers (n=163) and a quasi-systematic review of papers using LMMs (n=400). The survey reveals substantive concerns among psychologists using or planning to use LMMs and an absence of agreed standards. The review of papers complements the survey, showing variation in how the models are built, how effects are evaluated and, most worryingly, how models are reported. Using these data as our departure point, we present a set of best practice guidance, focusing on the reporting of ...

Of the many global concerns we face, the environmental issue is unique in many ways.
Bisphenol A (BPA) is one of the highest-volume chemicals produced worldwide, and human exposure to BPA is thought to be ubiquitous. Thus, there are concerns that the amount of BPA to which humans are exposed may cause adverse health effects. We examined many possibilities for why biomonitoring and toxicokinetic studies could come to seemingly conflicting conclusions. More than 80 published human biomonitoring studies that measured BPA concentrations in human tissues, urine, blood, and other fluids, along with two toxicokinetic studies of human BPA metabolism were examined. Unconjugated BPA was routinely detected in blood (in the nanograms per milliliter range), and conjugated BPA was routinely detected in the vast majority of urine samples (also in the nanograms per milliliter range). In stark contrast, toxicokinetic studies proposed that humans are not internally exposed to BPA. Available data from biomonitoring studies clearly indicate that the general population is exposed to BPA and is at ...
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 ...
The following information was provided by EPA in conjunction with the opportunity for public comment on the draft indicators for ACE3, which ran from March 8 - April 21, 2011. The public comment period is now closed.. Biomonitoring is the measurement of chemicals in human body fluids and tissues, such as blood, urine, breast milk, saliva, and hair. By obtaining measurements of pollutants in children, biomonitoring can be used to evaluate childrens exposure to environmental contaminants. Determining the levels of pollutants in women who may become pregnant, currently are pregnant, or currently are breastfeeding can be used to evaluate exposure to developing fetuses and infants.. The draft indicators for Americas Children and the Environment, Third Edition (ACE3) include biomonitoring indicators that were developed using data collected as part of the National Health and Nutrition Examination Survey (NHANES), conducted by the Centers for Disease Control and Prevention (CDC). The ACE3 ...

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 ...
OREANDA-NEWS. The deadline to submit written comments has been extended from September 28 to October 3, 2016. The Agency is aware that some members of the public may not have been able to access the Registry Internet site due to a technical issue that occurred between September 16 - 18, 2016. The issue is now resolved. As a result, the Agency has extended the deadline for the submission of public comments to October 3, 2016.. The Canadian Environmental Assessment Agency (the Agency) is conducting a federal environmental assessment of the proposed BURNCO Aggregate Mine Project, located on the northwest shore of Howe Sound, approximately 22 kilometres southwest of Squamish, British Columbia.. A public comment period will take place from August 15, 2016 to September 28, 2016 ...
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.. Unfortunately, these sky is falling claims are all too familiar. Claims questioning science and fear mongering over economic impacts have been made almost every time we talk about the need for stronger clean air protections - and they have never borne out. Clean air benefits outweigh costs of implementation by ...
