  • likelihood
  • Herein, ecological and commercial predictors of the likelihood of establishment of invasive populations were used to model risk associated with legal commercial imports of 23 species of boas, pythons, and relatives into the United States during the period 1989-2000. (ssrn.com)
  • characterization
  • Risk characterization includes two major components: risk estimation and risk description. (epa.gov)
  • An era consists of a description of the system and its components, hazard identification, effects assessment, exposure assessment, risk characterization and an evaluation which provides feedback for a possibly updated system description. (tudelft.nl)
  • Through Geosyntec's proactive field characterization efforts and the use of data management, GIS, geochemical modeling, and groundwater flow and transport modeling, our client, the regulatory agencies, and the public have benefited from a monitored natural attenuation demonstration for mercury in groundwater, the rapid completion of a significant soils removal action designed to manage long-term risks, and the restoration of local fisheries through rapid marsh remediation. (geosyntec.com)
  • ecology
  • Current ERA practices, however, incorporate very little ecology and base the risk estimates on the results of standard tests with several standard species. (nih.gov)
  • If a Tier 2 Risk Assessment estimates there is low risk to health or the local ecology from the contaminants, then there is no need to continue to the next tier. (greencap.com.au)
  • pose
  • Through the use of this approach it is highlighted that domestic discharge events pose a higher relative overall risk on a vessel-specific and cumulative annual bases than international discharges. (bioportfolio.com)
  • The need to capture spatio-temporal dynamics and possible interactions among service providers pose challenges for ecological models as a basis for decision making. (nih.gov)
  • considers
  • Young children and teenagers playing in and near portions of the river face noncancer risks that are 200 times greater than EPA considers safe. (epa.gov)
  • Young children playing for just one summer in the river in portions of the lower section - specifically, a ½-mile area between the Elm Street and Dawes Avenue Bridges - face noncancer risks 200 times higher than the hazard-index level EPA considers safe. (epa.gov)
  • Children, ages 5 to 12, who live or play alongside the river between the Elm Street and Dawes Avenue Bridges face noncancer risks 90 times higher than the hazard-index level EPA considers safe. (epa.gov)
  • Teenagers who live or play alongside the river face noncancer risks 200 times higher than hazard-index level EPA considers safe. (epa.gov)
  • A nine-year-old child who consumes one meal of fish from the Housatonic River each week for just one summer faces noncancer risks about 900 times higher than the hazard-index EPA considers safe. (epa.gov)
  • evaluate
  • Must be able to evaluate, select, and apply standard risk assessment techniques, procedures and criteria to perform technical assignments and QA/QC activities. (environmentalcareer.com)
  • In addition, the report suggests how to estimate, describe, and communicate risk and how to evaluate management alternatives. (epa.gov)
  • Its goal is the collection of data in sufficient quantity and quality to determine current site conditions, support a risk assessment for the site surfaces, and evaluate what further remedial action is required to achieve permanent closure of these three sites that will protect both human health and the environment. (unt.edu)
  • These contaminant indicators will be used to evaluate ecological condition. (epa.gov)
  • evaluations
  • These risk evaluations, which were peer reviewed and endorsed by EPA Headquarters, support EPA's position that the entire two-mile section of river may present an imminent and substantial endangerment to human health and the environment. (epa.gov)
  • contaminants
  • The FORTRAN77 ecological risk computer model--ECORSK.5--has been used to estimate the potential toxicity of surficial deposits of radioactive and non-radioactive contaminants to several threatened and endangered (T and E) species at the Los Alamos National Laboratory (LANL). (unt.edu)
  • This integration results in the production of hazard indices which, when compared to risk evaluation criteria, estimate the potential for impact from consumption of contaminants in food and ingestion of soil. (unt.edu)
  • estimate
  • When these methods are applied in practice, it depends on the situation at hand which technique is most suitable to estimate risk. (tudelft.nl)
  • species
  • Risks due to invasive or non-indigenous species, genetically modified organisms, and climate change are being evaluated. (sra.org)
  • In this study relative ecological risk assessment was done for future potential introductions of three species in the Canadian Arctic: periwinkle Littorina littorea, soft shell clam Mya arenaria and red king crab Paralithodes camtschaticus. (bioportfolio.com)
  • This work can serve as an approach to help build a list of potential high risk species-a "grey" watch list-for the Canadian Arctic, and provides useful information for consideration in future decision making actions such as the identification of high risk pathways, species and ports. (bioportfolio.com)
  • Recommendations for reducing risk of establishment of invasive populations of snakes and/or pathogens include temporary quarantine of imports to increase detection rates of nonnative pathogens, increasing research attention to reptile pathogens, reducing the risk that nonnative snakes will reach certain areas with high numbers of federally listed species (such as the Florida Keys), and attempting to better educate individuals purchasing reptiles. (ssrn.com)
  • Science
  • Many countries include an ecological risk assessment in their registration requirements, but risk assessment is an evolving science, and it is important that the current best practices are understood and implemented properly, particularly in scientifically emerging regions. (degruyter.com)
  • ERASC develops responses that reflect the state of the science for ecological risk assessment and also provides a communication point for the distribution of the responses to other interested parties. (epa.gov)
  • potential
  • The integration of FIMAD data and ARC/INFO using ECORSK.5 allows the generation of spatial information from a gridded area of potential exposure called an Ecological Exposure Unit. (unt.edu)
  • This report is of potential use to ecologists, hydrologists, watershed managers, risk assessors, landscape ecologists, and other scientists and managers seeking to increase the use of environmental assessment data in decision making. (epa.gov)
  • data
  • Data on ecological variables were collected from multiple sources, while data on commercial variables were collated from import records maintained by the U.S. Fish and Wildlife Service. (ssrn.com)
  • development
  • After each presentation, and during breaks in the programme, participants were able to discuss all aspects of ecological risk assessment, including good modelling practices, scenario development, and local requirements. (degruyter.com)
  • A risk assessment report can provide information to support a site owner, auditor or regulator to decide on a site's suitability for use or development, even if some contamination is present. (greencap.com.au)
