About this program

The National Institute of Environmental Health Sciences (NIEHS), a component of the Department of Health and Human Services National Institutes of Health, funds research on environmental exposures and their biological effects across the lifespan through the Environmental Health program (CFDA 93.113), with the most recent award dated September 30, 2030.

The program supports mechanistic, epidemiological, and translational research on how chemical, physical, and biologically derived environmental exposures—including air pollutants, metals, persistent organic chemicals, endocrine-disrupting chemicals, microplastics, and extreme weather events—affect human health. Funded research encompasses exposure assessment technology development, studies of biological pathways underlying exposure effects, epidemiological investigations of environmental health associations, community-engaged research, and strategies to reduce exposure burden at individual and population levels. The portfolio reflects strong support for training and career development, as well as commercial tool development through SBIR and STTR mechanisms.

Award activity shows sustained but declining recent disbursement rates: 278 awards in 2024, 188 in 2025, and 175 in 2026, with only 10 recorded in 2027 and 1 in 2030, likely reflecting data lag. The program has awarded 8,551 grants since 1975, obligating $10.29 billion in federal dollars. The portfolio is heavily dominated by Project Grants (94 percent of awards), with smaller shares of Block Grants (4 percent) and Cooperative Agreements (2 percent). Funding concentrates within NIEHS itself: the National Institute of Environmental Health Sciences directly managed 3,085 awards worth $7.15 billion federal dollars, while the broader NIH funding apparatus (including NIH Office of the Director and other institutes) accounts for the remainder of the $10.29 billion total obligated.

Representative recent awards reflect the scope: development of mass spectrometry methods for copper toxicity response in aquatic organisms ($97 thousand); investigation of chaperone-mediated condensate dispersal in environmental stress responses ($50 thousand); studies of aryl hydrocarbon receptor and microbiome roles in hidradenitis suppurativa ($55 thousand); wildfire smoke exposure impacts on neuroinflammation and ovarian hormones ($40 thousand); and epidemiological analyses of wildfire smoke, extreme heat, and mental health outcomes ($50 thousand). Larger R01 and R21 awards support mechanistic work on PFAS impacts on cognitive aging ($762 thousand), tire and road wear particle toxicity ($406 thousand), environmental modifiers of skin carcinogenesis ($813 thousand), and e-cigarette impacts in pregnancy ($473 thousand).

Recent grant opportunities include several mechanism-focused solicitations: RFA-ES-28-004 on Children's Environmental Health Research Translation Centers (P2C); RFA-ES-27-009 on mechanistic toxicology of metals; and multiple career development awards (KT1/R00, KR1, KC1, KS1) posted August 2026. The program also offers coordinating center mechanisms—RFA-ES-27-003 on microplastics research coordination (U24) and RFA-ES-28-003 on health and extreme weather data coordination (U2C)—as well as solution-focused hubs (RFA-ES-28-002, U54). Broad investigator-focused opportunities include PAR-28-037 on R35 Investigator Awards and standard R01 mechanisms across parent announcements. Predoctoral and postdoctoral training support is available through F31/F32 fellowships and F99/K00 transition awards. SBIR/STTR opportunities for small businesses remain active under standing parent announcements PAR-27-100 and PAR-27-102.

Objective and description

Objective

The mission of the National Institute of Environmental Health Sciences (NIEHS) is to research how the environment affects biological systems across the lifespan and to translate this knowledge to reduce disease and promote health.

Description

Environmental exposures considered are exogenous, and range from chemical, physical, and biologically derived (non-pathogenic) factors experienced through inhalation, ingestion, or ocular or dermal contact, individually or as mixtures. Research supported includes the development of technologies to assess human environmental exposures and biological impacts of exposure; mechanistic understanding of exposures on biological systems including the use of environmentally derived analytes as probes of fundamental biological mechanisms; epidemiological studies of the health effects of environmental exposures including the interactions between environmental and genetic or other endogenous factors; community engaged research; and the identification of strategies to reduce the burden of exposure and improve human health at the individual and population levels. NIEHS supports training and career development throughout the career trajectory and the development of commercial tools and technologies through SBIR and STTR programs.

Candidates for Academic Career Awards Awards and Midcareer Investigator Awards in Patient Oriented Research must have a doctoral degree and peer-reviewed, independent, research support at the time the award is made. Candidates for Mentored Clinical Scientist Development Awards and Mentored Patient Oriented Research Career Development Awards must have a clinical degree or its equivalent and must have initiated post graduate clinical training. Candidates holding a Ph.D. degree are ineligible. Candidates who have served as principal investigators on PHS-supported research projects are ineligible. A candidate for Academic Career Awards must have a clinical or research doctorate degree. Those eligible for the Development Award must be able to devote at least 75 percent effort. SBIR grants can be awarded only to domestic small businesses (entities that are independently owned and operated for profit, are not dominant in the field in which research is proposed, and have no more than 500 employees). Primary employment (more than one-half time) of the principal investigator must be with the small business at the time of award and during the conduct of the proposed project. In both Phase I and Phase II, the research must be performed in the U.S. and its possessions. STTR grants can be awarded only to domestic small business concerns (entities that are independently owned and operated for profit, are not dominant in the field in which research is proposed and have no more than 500 employees) which "partner" with a research institution in cooperative research and development. At least 40 percent of the project is to be performed by the small business concern and at least 30 percent by the research institution. In both Phase I and Phase II, the research must be performed in the U.S. and its possessions. To be eligible for funding, a grant application must be approved for scientific merit and program relevance by a scientific review group and a national advisory council. Centers: A university-based, nonprofit research institution, or for-profit organization proposing an integrated research program established to accomplish a stated mission, covering activities ranging from very basic research to the actual application of research results in the prevention and control of environmental health problems, may submit an application under the direction of a named Center Director. National Research Service Awards: (1) Nonprofit domestic organizations may apply for the Institutional NRSA; (2) Individual NRSA awardees must be nominated and sponsored by a public for-profit or nonprofit private institution having staff and facilities appropriate to the proposed research training program; (3) all awardees must be citizens or have been admitted to the United States for permanent residence; (4) to be eligible, predoctoral awardees must have completed the baccalaureate degree and postdoctoral awardees must have a professional or scientific degree (M.D., Ph.D., D.D.S., D.O., D.V.M., Sc.D., D.Eng., or equivalent domestic or foreign degree).

Award procedure

Made on the basis of dual review by peer groups of all applications. The first level of reviews is by a study section for scientific merit. In addition, a national advisory council provides a secondary level of review for all applications. As required by P.L. 109-482, the NIH Health Reform Act of 2006, all research grant and cooperative agreements must undergo Advisory Council/Board review and approval prior to funding. Review of Individual NRSA applications by an Advisory Council/Board is not required. Final approval of these recommendations and decisions concerning funding are made by the Director, NIEHS.

Time to approval or disapproval

Receipt, review and approval processes range in length from six to nine months.

Renewals
