Aquatic Life Benchmarks and Ecological Risk Assessments for Registered Pesticides

The aquatic life benchmarks for freshwater species and ambient water quality criteria for registered pesticides in the United States are provided in the table below. The benchmarks are based on toxicity values found in scientific studies that are reviewed by EPA and used in the Agency's most recent publicly available ecological risk assessments. EPA's most recent ecological risk assessment for an individual pesticide can be found by clicking on the underlined hyperlink for the pesticide found in the table below.

The studies, upon which these benchmarks are based, are specified in regulation 40 CFR 158 and are generated by the pesticide company seeking the registration of the pesticide. In reviewing these studies, EPA uses documented Harmonized Test Guidelines to evaluate the quality and utility of the industry-submitted studies. EPA also reviews studies from a wide range of environmental laboratory and field studies available in the public scientific literature to assess environmental risk. Each aquatic life benchmark is based on the most sensitive, scientifically acceptable toxicity endpoint available to EPA for a given taxon or group of related organisms (for example, freshwater fish). EPA's goal is to add to these benchmarks and assessments on an annual basis.

Relationship to Ambient Water Quality Criteria

EPA's Office of Pesticide Programs (OPP) and EPA's Office of Water (OW) have responsibilities for evaluating aquatic toxicity data to assess the ecological effects of chemicals in surface water. Effects assessments under both program offices are developed with high quality data according to parallel but somewhat different rigorously peer-reviewed assessment methods.

  • OW uses aquatic toxicity data to develop ambient water quality criteria that can be adopted by states and tribes to establish water quality standards under the Clean Water Act. National recommended water quality criteria are available for 25 pesticides. Procedures for deriving the criteria are described in OW’s Guidelines for Deriving Numerical National Water Quality Criteria for Protection of Aquatic Organisms and require, for acute criteria, that data be available for at least eight families.
  • As required by the Federal Insecticide, Fungicide, and Rodenticide Act, OPP uses aquatic toxicity data in its ecological risk assessments for a large number of pesticide registration decisions. OPP's procedures for conducting pesticide effects assessments are described in our Overview of the Ecological Risk Assessment Process; and rely, at a minimum, on data for the most sensitive tested effects concentration for each taxon.
  • Both the OW and OPP methods assess and characterize effects for protecting aquatic communities.

Use of Aquatic Life Benchmarks

EPA worked initially with the U.S. Geological Survey to identify aquatic ecotoxicity benchmark values from risk assessments developed by EPA for individual pesticides during the recently completed re-registration program. The Overview of the Ecological Risk Assessment Process and ecological risk assessments developed for individual pesticides provide useful information for understanding how these ecotoxicity benchmarks were developed and the uncertainties associated with each benchmark. Comparing a measured concentration of a pesticide in water with an aquatic life benchmark can be helpful in interpreting monitoring data and in identifying and prioritizing sites and pesticides that may require further investigation.

These aquatic life benchmarks are extracted from the most recent publicly available OPP risk assessment for the individual pesticide and are based on the most sensitive aquatic toxicity data of the distribution for each taxa. Aquatic life benchmarks, developed for baseline risk assessments, are estimates of the concentrations below which pesticides are not expected to harm aquatic life. OPP may further refine a risk assessment based on the full distribution of toxicity data for a given species, using point estimates, species sensitivity distribution approaches, or probabilistic methods.

OPP and OW are continuing to work together in harmonizing their high quality, peer-reviewed scientific approaches that now underlie both programs. A harmonized approach will result in consistent tools and approaches for all stakeholder communities to use in ensuring the protection of aquatic ecosystems

Footnotes

  • 1 Benchmark = Toxicity value x LOC. For acute fish, toxicity value is generally the lowest 96-hour LC50 in a standardized test (usually with rainbow trout, fathead minnow, or bluegill), and the LOC is 0.5.

  • 2 Benchmark = Toxicity value x LOC. For chronic fish, toxicity value is usually the lowest NOEAC from a life-cycle or early life stage test (usually with rainbow trout or fathead minnow), and the LOC is 1.

  • 3 Benchmark = Toxicity value x LOC. For acute invertebrate, toxicity value is usually the lowest 48- or 96-hour EC50 or LC50 in a standardized test (usually with midge, scud, or daphnids), and the LOC is 0.5.

  • 4 Benchmark = Toxicity value x LOC. For chronic invertebrates, toxicity value is usually the lowest NOAEC from a life-cycle test with invertebrates (usually with midge, scud, or daphnids), and the LOC is 1.

  • 5 Benchmark = Toxicity value x LOC. For acute nonvascular plants, toxicity value is usually a short-term (less than 10 days) EC50 (usually with green algae or diatoms), and the LOC is 1.

  • 6 Benchmark = Toxicity value x LOC. For acute vascular plants, toxicity value is usually a short-term (less than 10 days) EC50 (usually with duckweed) and the LOC is 1.

  • 7 An acute-to-chronic ratio was used to calculate the chronic endpoint and benchmark, which may underestimate chronic toxicity.

  • 8 Although the underlying acute toxicity value is greater than or equal to the chronic toxicity value, the acute benchmark is lower than the chronic benchmark because acute and chronic toxicity values were multiplied by LOC values of 0.5 and 1, respectively.

  • 9 Original toxicity values are in micrograms of acid equivalents per liter. For 2,4-D and 2,4-DB, the toxicity values selected were the lowest available values for the acid or salt forms. For MCPA, acute toxicity values were the lowest for the acid, salt or ester forms, and chronic toxicity values were the lowest of the acid and salt forms. For Dicamba the toxicity values were the lowest of the acid or salt forms. (Selection was consistent with risk quotients in the cited EPA references.)

  • 10 The acute toxicity values were the lowest of the acid, salt or ester forms, and the chronic toxicity values were the lowest of the acid and salt forms of triclopyr. (Selection was consistent with risk quotients in the cited EPA reference.)

  • 11 Toxicity values and benchmarks apply to permethrin. If monitoring data represent only the cis isomer of permethrin in water, comparison with benchmarks may underestimate potential toxicity.

Generic footnotes

  • Empty cells indicate that acceptable aquatic toxicity values are not available.

  • Benchmarks preceded by a "greater-than" symbol (for example, >265,000) were derived from a "greater-than" value and may overestimate toxicity.  Conversely, benchmarks preceded by a "less-than" symbol (for example, <1,500) were derived from a "less-than" value and may underestimate toxicity.
