General information:

The aquatic life benchmarks (for freshwater species) provided are based on toxicity values reviewed by the U.S. Environmental Protection Agency (EPA) and used in the Agency's most recent risk assessments developed as part of the decision-making process for pesticide registration. Each Aquatic Life Benchmark is based on the most sensitive, scientifically acceptable toxicity endpoint available to EPA for a given taxon (for example, freshwater fish) of all scientifically acceptable toxicity data available to EPA.  Acute and chronic benchmarks are developed for freshwater fish and invertebrates and for aquatic vascular and nonvascular plants.  Each of the chemical benchmarks is linked to the EPA ecological risk assessment chapter from which they were used.  These aquatic benchmarks are extracted from the most recent publically available OPP risk assessment for the pesticide and are based on the most sensitive aquatic toxicity data of the distribution for each taxa. Benchmarks, developed for baseline risk assessments, are estimates of the concentrations below which pesticides are not expected to harm aquatic life. Comparing a measured concentration of a pesticide in water with an aquatic life benchmark can be helpful in interpreting monitoring data, and to identify and prioritize sites and pesticides that may require further investigation.

Disclaimer for Information available in EPA OPPALB:

No Disclaimer.

Hazard information:

Each Aquatic Life Benchmark is based on the most sensitive, scientifically acceptable toxicity endpoint available to EPA for a given taxon (for example, freshwater fish) of all scientifically acceptable toxicity data available to EPA.  Acute and chronic benchmarks are developed for freshwater fish and invertebrates and for aquatic vascular and nonvascular plants.

Search capabilities:

Database is arranged in alphabetical order of pesticide active ingredient common name and can be searched based on CAS number as well.

Maintenance:

The database is maintained by the EPA Office of Pesticide Programs’ Environmental Fate and Effects Division.

Peer review:

The database has been subject to extensive EPA internal peer review as well as review by other Federal agencies.
