1996 Grants for Research
(APPLICATION SUBMISSION CLOSING DATE: MAY 1, 1996)
The U.S. Environmental Protection Agency (EPA) invites research grant applications in the following areas of special interest to its mission:
11. Endocrine disruptors
12. Role of Interindividual Variation in Human Susceptibility to Cancer
13. Risk-Based Decisions for Contaminated Sediments
This invitation provides relevant background information, summarizes EPA's interest in the topic areas, and describes the application and review process.
BackgroundDuring fiscal year 1995 EPA increased funding for its investigator initiated research grants program. For fiscal year 1996, EPA anticipates a second increase, subject to the 1996 Federal appropriation process. In December 1995 EPA issued a Request for Applications (RFA) which summarized its interest in 9 programmatic areas. This announcement supplements that RFA and solicits research proposals in 3 additional topical areas. Additional programs involving cooperation with the National Science Foundation and other agencies were announced separately.
EPA Mission and R & D StrategyThe mission of EPA - and its unique role - is the protection of both environmental quality and human health through effective regulations and other policy implementation. Achievement of this mission requires the application of sound science to the assessment of environmental problems and evaluation of possible solutions. A significant challenge is to support both long-
term research that anticipates future environmental problems as well as to fill significant gaps in knowledge relevant to meeting current Agency goals. This Request for Applications and the joint solicitations with other agencies are important steps toward ensuring that EPA can provide a sound scientific foundation as the country enters a new generation of environmental protection.
EPA recently reorganized its research programs to focus on the reduction of uncertainty associated with risk assessment and reduction of risks to human health and ecosystems. Through its laboratories and through grants to universities and other not-for-profit institutions, EPA will promote research in both domains, according the highest priority to those areas where risk assessors are most in need of new concepts, methods, and data. At the same time, EPA will foster the development and evaluation of new risk reduction technologies across a spectrum, from pollution prevention, through end-of-pipe controls, to remediation and monitoring. In all areas, EPA is interested in research that recognizes issues relating to environmental justice, the Agency's effort to achieve equal protection from environmental and health hazards for all people without regard to race, economic status, or culture.
Research Programs of Interest
11. Endocrine DisruptorsReports have been accumulating that both humans and wildlife species have experienced adverse health consequences resulting from exposure to environmental pollutants that interact with the endocrine system. These pollutants are collectively referred to as "endocrine disruptors," a term broadly defined as "an exogenous agent that interferes with the production, release, trans
port, metabolism, binding, action, or elimination of natural hormones in the body responsible for the maintenance of homeostasis and the regulation of reproductive and developmental processes." The Agency is concerned with potential effects posed by environmental agents that act as hormones or anti-hormones, as well as chemicals or mixtures which perturb components of the endocrine system through as yet uncharacterized modes of action.
To date, problems have been identified primarily in domestic or wildlife species with high exposure to organochlorine compounds, including DDT and its metabolites, PCBs and dioxins, some organometals, unidentified components of certain types of complex effluents and emissions, and/or to naturally occurring plant estrogens. Whether similar effects are occurring in the general human or wildlife population is unknown. Several reports of declines in the quality and quantity of sperm production in humans over the last four decades and reported increases in incidence of certain cancers (breast, prostate, testicular) have led to speculation about environmental etiologies. Correlational evidence suggests that specific populations of animals such as birds, fish, reptiles, and mammals have been, or currently are being, adversely impacted by exposure to environmental contaminants that may manifest effects through the endocrine system.
The objective of EPA's Endocrine Disruptor research program is to evaluate potential health effects associated with endocrine disruptors and to determine the extent of current exposures. Investigator-initiated grant proposals are sought in four broad areas: (1) human health effects, (2) ecological health effects, (3) human exposure evaluations, (4) ecological exposure evaluations.
Examples of research topics of interest to EPA include:
- Refinement of methods to monitor and characterize exposure of
humans and/or wildlife to endocrine disruptors, including aspects
such as exposure half-life, speciation, uptake, and phase equilibrium.
- Development and validation of models to estimate exposure to
endocrine disruptors from different sources via multiple pathways.
- Development and validation of biomarkers of endocrine disruptor
exposure and effect.
- Development and validation of in vitro and short-term in vivo
test systems to screen for chemicals with specific mechanisms
of action expressed via different endocrine pathways; test systems
that are applicable across multiple phylogenetic levels are of
- Development of Physiologically-Based Pharmacokinetic (PB-PK),
Physiologically-Based Toxicokinetic (PB-TK), and Biologically-Based
Dose-Response (BBDR) models that incorporate key species-specific
parameters critical to the extrapolation of effects across phyla.
- Refinement and validation of methods and models that relate effects observed at subcellular levels to adverse impacts in individuals (both human and wildlife species) and in wildlife populations.
Funding: Up to $3.5 million is expected to be available in fiscal year 1996 for awards in this program area. The projected award range is $100,000 - $200,000/year for up to 3 years.
12. Role of Interindividual Variation in Human Susceptibility to Cancer
BackgroundIn 1994, the National Academy of Sciences released the report, Science and Judgment in Risk Assessment. This report, which was produced in response to the Clean Air Act Amendments of 1990, evaluated risk assessment methods at EPA and drew a series of conclusions and recommendations. Included was the issue of variation in human susceptibility. On this issue, the report concluded that EPA's consideration of interindividual variability has been limited largely to noncarcinogenic effects, such as asthmatic responses to sulfur dioxide exposure, and suggested that EPA include consideration of interindividual variability in its cancer risk assessments. The NAS recommended that:
- Federal agencies should sponsor molecular, epidemiological,
and other types of research to examine the causes and extent of
interindividual variability in susceptibility to cancer and the
possible correlations between susceptibility and such covariates
as age, race, ethnicity, and sex. Results should be used to refine
estimates of risks to individuals and the general population.
- EPA should increase its efforts to validate or improve the default assumption that humans on average have the same susceptibility as humans in epidemiological studies, the most sensitive animals tested, or both.
DescriptionIn this RFA, EPA is interested in: (1) the identification of human genetic polymorphisms which can affect carcinogenic risk from environmental agents, (2) the quantitative relationship of these polymorphisms to the risk of cancer from environmental agents, and (3) the distribution of such polymorphisms in the general population. Response to this RFA should address human variation in susceptibility with regard to polymorphisms and a specific chemical carcinogen of concern to the Agency.
Funding: Up to $2.0M is expected to be available in Fiscal Year 1996 for this program area. The projected award range is $100,000 - $200,000/year for up to 3 years.
13. Risk-Based Decisions for Contaminated SedimentsMany persistent chemical contaminants in aquatic ecosystems eventually accumulate in sediments where they may adversely affect the benthic biota, become a source of contamination in the water column, accumulate in biological tissues, and enter pelagic and human food chains. Contaminated sediments now appear to be the main source of toxic contaminants in many bays, lakes, and rivers. For example, of the Great Lake's 42 Areas of Concern, 33 have degraded water quality problems associated with contaminated sediments. Because of their potential adverse impacts, the long periods of time associated with natural assimilation of many in-place contaminants, and the high costs of mitigation, sediments have become a focus of concern for EPA.
The following areas of research provide the framework for the competition:
Risk-Based AssessmentsHazard Identification
All assessment techniques, either biological or chemical, need validation of their ability to predict impacts on indigenous aquatic communities. When laboratory data and test systems are being used to predict contaminated sediment impacts, there needs to be a strong lab-to field association. Research is needed to validate these techniques using a risk-based approach. Validation efforts must consider the uncertainty associated with the assessment and the degree of protection offered to the aquatic community.
The effects of contaminants associated with sediments is often manifested through aquatic food chains. Research and mathematical modeling is needed to accurately characterize the transfer of toxic substances from their source to the sediments, from sediments to organisms, and organism to organism.
Short-term sediment toxicity test methods to examine aquatic life effects using laboratory animals exist. In addition, there are some theoretical models to predict whether certain single chemical concentrations will have an adverse impact on benthic communities. Most contaminated sediments contain mixtures of chemicals; thus, mixture toxicity research and modeling both for organic substances and trace metals are needed to complement single chemical assessments. Further research is needed to expand the number and kind of species being tested.
Knowledge of the fate and bioavailability of toxic substances in sediments is sometimes highly speculative. Additional knowledge is needed on: (1) the fate of toxic substances during resuspension, especially during severe events, and biological, chemical and physical factors con
trolling resuspension of sediments, (2) the spatial (horizontal and vertical) and temporal extent of sediment contamination, and (3) biogeochemical partitioning between sediments, water, and biota to better predict bioavailability of chemicals believed to have adverse impacts.
Risk ManagementSediment Treatment
Contaminated sediments requiring treatment can result from either sediment management operations (e.g., maintenance dredging) or remediation efforts. The environmental risks associated with these sediments need to be reduced. For example, better methods to predict the extent to which dredging operations resuspend and transport contaminants to less contaminated areas are needed. Research is needed to develop innovative treatment options for sites with large volumes of contaminated sediment (e.g., harbors).
Proposals that address the above mentioned needs are invited. Proposals must relate how the research will facilitate better risk assessments and risk management decisions.
Funding: Approximately $2.0 million is expected to be available for awards under this program area. The projected award range is $100,000 - $200,000/year for up to 3 years.

Profit making firms are eligible only under certain laws, and then under restrictive conditions, including the absence of any profit from the project. Federal agencies and federal employees are not eligible to participate in this program. Potential applicants who are uncertain of their eligibility should contact EPA's Grants Operations Branch at (202) 260-9266.
Review and SelectionAll grant applications are initially reviewed by EPA to determine their legal and administrative acceptability and responsiveness to this solicitation. Acceptable applications are then reviewed by an appropriate technical peer review group. This review is designed to evaluate and rank each proposal according to its scientific merit. Each review group is composed primarily of non-EPA scientists, engineers, social scientists, and/or economists who are experts in their respective disci
plines. All reviewers are proficient in the technical areas that they are reviewing. The reviewers use the following criteria in their reviews:
- quality of the research plan (including theoretical and/or experimental
design, originality, and creativity);
- qualifications of the principal investigator and staff, including
knowledge of relevant subject areas;
- potential contribution of the research to advancing scientific
knowledge in the environmental area;
- availability and adequacy of facilities and equipment; and
- budget justification -- justification for equipment will receive
- responsiveness to solicitation objectives.
Funding decisions are the sole responsibility of EPA. Grants are selected on the basis of technical merit, relevancy to the research priorities outlined, program balance, and budget.
EPA anticipates making awards from this RFA by September 1996.
Proprietary InformationBy submitting an application in response to this solicitation, the applicant grants EPA permission to share the application with technical reviewers both withitside of the Agency. Applications containing proprietary or other types of confidential information will be immediately returned to the applicant without review.
Funding MechanismThe funding mechanism for all awards issued under this solicitation will consist of a grant between EPA and the recipient. In accordance with Public Law 95-224, a grant is used to accomplish a public purpose of support or stimulation authorized by Federal statute rather than acquisition for the direct benefit of the Agency. In using a grant instrument, EPA anticipates that there will be no substantial involvement during the course of the grant between the recipient and the Agency.
