Final Fate Td

[Ronald Gruzinsky]

TheChemical Aquatic Fate and Effects (CAFE) database is a software program you can use to estimate the fate and effects of thousands of chemicals, oils, and dispersants. CAFE serves as a tool to help responders in their assessment of environmental impacts from chemical or oil spills into an aquatic environment. Using CAFE, you can choose between four different spill scenarios: chemical, oil only, dispersant only, and dispersants mixed with oil.

Also included in CAFE are Short Exposure Risk Reports for a selected number of chemicals, and a User-Added section that allows you to add your own data to SSDs (desktop version only).

CAFE Fact Sheet [PDF, 410 KB]: Learn more about basic features of CAFE in this short fact sheet. CAFE was developed by NOAA's Office of Response and Restoration, in collaboration with Research Planning, Inc.

We know that Beethoven strived to overcome many obstacles in his life and documented his aspirations to prevail, despite his ailments. Whatever the specific reason for including this particularly profound passage from the Iliad, in the end, it seems that Beethoven relinquished to fate. Fate now conquers.

The Exposure and Fate Assessment Screening Tool (E-FAST 2014) provides estimates of the concentrations of chemicals released to air, surface water, landfills, and consumer products. Estimates provided are potential inhalation, dermal and ingestion dose rates resulting from releases of chemicals. Modeled estimates of concentrations and doses are designed to reasonably overestimate exposures, for use in an exposure assessment in the absence of or with reliable monitoring data.

The new version of E-FAST (2014) contains the same user interface, workflows, calculations, and report formats as version 2.0. However, the system has been updated to be compatible with newer Windows operating systems and to reflect the latest exposure factors from the EPA Exposure Factors Handbook (U.S. EPA, 2011).

E-FAST 2014 calculates appropriate human potential dose rates for a wide variety of chemical exposure routes, and estimates the number of days per year that an aquatic ecotoxicological concern concentration will be exceeded for organisms in the water column. Version 2014 includes a new entry page where the user enters physical/chemical property and chemical fate information. The user selects the exposure modules that need to be run in E-FAST 2014 and this will determine what p-chem and fate information is required. E-FAST 2014 also uses the Screen 3 ambient air model to estimate outdoor air exposures. E-FAST 2014 also has the capability of searching for endangered species in the vicinity of specific facilities.

To execute the E-FAST 2014 model to assess general population exposure and aquatic environmental exposure and risk resulting from industrial releases, the user enters: amount of chemical releases; media of release; days per year of release; certain chemical properties; where possible, detailed release location data; if no detailed location data is available, generic industry codes can be applied. To execute the consumer exposure assessment modules in E-FAST 2014, the user enters: the type of product; weight fraction; vapor pressure; and molecular weight.

The program produces a summary sheet with multimedia concentrations from multiple release activities. Risk assessors can use the potential dose estimated by E-FAST 2014 in assessing potential exposure and risk at a screening level.

The consumer exposure portions of E-FAST have been peer reviewed by experts outside EPA, and EPA has developed E-FAST 2014 using the external peer review comments for the general population, down-the-drain, environmental exposure and risks aspects of E-FAST.

The E-FAST 2014 Documentation Manual is based on the previous version of the tool, E-FAST V2.0. The manual is still relevant to the current 2014 version because no changes were made to the calculations or processing of calculations in the model.

Representative measured data obtained under realistic conditions are generally more accurate than modeled estimates, and are needed to develop predictive models. However, models can provide useful fate and exposure estimates where data gaps exist. EPA's models and tools are intended to be used by scientists and engineers familiar with exposure assessment principles.

Quality assurance and quality control of measured data and models are important components of EPA exposure and fate assessments. Understanding the equations, limitations, default values, and assumptions is important when using models. For risk assessment purposes, a quantitative exposure assessment approach is needed and exposure information (concentrations or doses) must be clearly linked to the hazard identification and relevant toxicological endpoints.

Use of Monitoring Data: The most accurate way to characterize exposure is usually to conduct a well-designed monitoring study that concurrently measures environmental concentrations and internal doses over time.

Use of Models: The screening level tools often make simplifying assumptions which are protective by design (for example, assuming that people live near chemical discharge locations). Higher tier tools are more complex and allow for more realistic exposure assessments, such as using census data and a measure of the distance between the location of the chemical release and the populations living nearby.

The exposure assessment models in this website include standard default values which can be changed by the user. Where possible, language which describes the impact of the standard assumptions and default values on the exposure result is included. The default values were carefully selected but often reflect general rather than specific exposure conditions. If the standard assumptions and default values are applied when using the model, the descriptive language should be incorporated into the results. Using specific exposure related data in the models will enable you to tailor the model to the exposure scenario of interest and refine estimates of exposure.

Chemical Screening Tool for Exposures and Environmental Releases (ChemSTEER): Estimates environmental releases and worker exposures resulting from chemical manufacture, processing, and/or use in industrial and commercial workplaces.

Internet Graphical Exposure Modeling System (IGEMS): Is a modernization of EPA's older Graphical Exposure Modeling System and PCGEMS tools. IGEMS brings together in one system several EPA environmental fate and transport models and some of the environmental data needed to run them. EPA is requesting public comment on the use of this model.

Genetic, epigenetic and environmental inputs are deeply intertwined, making it difficult to disentangle their respective contributions to cell fate decisions8,9, and epigenetic reprogramming is a major contributor to tumour plasticity and adaptation10,11. Over recent decades, large-scale projects expanded the known repertoire of cancer-associated genetic mutations affecting epigenetic factors12,13, including chromatin remodellers and modifiers, which regulate histone marks14,15, DNA methylation16, micro-RNAs17 and 3D-genome folding18, corroborating the role of epigenetic aberrations in the aetiology of haematological and solid malignancies19,20. Indeed, epigenetic modifications are used as biomarkers and are targeted by epi-drugs in cancer therapy21. Tumorigenesis is therefore associated with genetic as well as epigenetic determinants22,23,24,25. The fact that several hallmarks of human cancer24,26 may be acquired through epigenome dysregulation suggests that epigenetic alterations play causal roles in cancer4,27,28 and in metastatic progression29,30,31,32,33. In some paediatric cancers, such as posterior fossa ependymoma, low numbers of mutations were detected, consistent with the possibility that epigenetic changes may drive tumorigenesis30. These observations suggest that cancer is not solely a consequence of DNA mutations34,35, but whether purely non-genetic reprogramming mechanisms are sufficient to initiate tumorigenesis remains an open question. Polycomb group (PcG) proteins are epigenetic factors forming two main classes of complexes called Polycomb Repressive Complex 1 and 2 (PRC1 and PRC2, respectively), which are highly conserved from fly to human and play a critical role in cellular memory by repressing developmental genes throughout development36. PcG dysregulation leads to cell fate changes37, developmental transformations and is associated with cancer38. PRC2 deposits the H3K27me3 repressive mark, whereas PRC1, which contains the PH, PC, PSC and the SCE subunits in flies, is responsible for H2AK118Ub deposition36. Contrasting with the redundancy found in mammals36, most PcG components are encoded by a single gene in Drosophila, making this system more tractable for functional studies39.
