ENANTIOMER-SPECIFIC MEASUREMENTS OF CURRENT-USE PESTICIDES IN AQUATIC SYSTEMS

Published by U.S. EPA Office of Research and Development (ORD) | U.S. Environmental Protection Agency | Metadata Last Checked: June 27, 2025 | Last Modified: 2017-03-21
These data are provided in six data tables. Each data table corresponds to a set of samples obtained from a different organization in California that were analyzed for this study. Metadata is presented as table captions, column headers and/or row information for each set of samples. The metadata for each sample set/table varies but includes some combination of the following: organization providing the samples; units of measure (as appropriate); fipronil enantiomer fraction (EF), bifenthrin EF, cis-permethrin EF; racemic standard EFs for fipronil, bifenthrin, and cis-permethrin analyzed with each set of samples [these data were measured for the study]; sample description including location collected, type of sample, date of sample collection, fipronil, bifenthrin, and cis-permethrin concentrations; pavement treatment information including compounds used for concrete treatment, formulation applied to concrete, number of days since treatment; fish and fish treatment information including dose, number of days since dose, fish mortality status, fish length and weight; percent survival in toxicity tests. Additionally, some data analysis information is provided that indicates whether the EF measured in a given sample is not measured, the compound was not detected, racemic or non-racemic. This dataset is associated with the following publication: Ulrich , E., P. TenBrook , L. McMillan, O. Wang, and W. Lao. Enantiomer‐specific measurements of current‐use pesticides in aquatic systems. ENVIRONMENTAL TOXICOLOGY AND CHEMISTRY. Society of Environmental Toxicology and Chemistry, Pensacola, FL, USA, 37(1): 99-106, (2018).
