The chemical aquatic fate and effects database (CAFE), a tool that supports assessments of chemical spills in aquatic environments

0
The Chemical Aquatic Fate and Effects (CAFE) database is a centralized repository that allows for rapid and unrestricted access to data. Information in CAFE is integrated into a user‐friendly tool with modules containing fate and effects data for 32,377 and 4,498 chemicals, respectively, with toxicity data summarized in species sensitivity distributions (SSDs) with associated 1st and 5th percentile hazard concentrations (HC). An assessment of data availability relative to reported chemical incidents showed that CAFE had fate and toxicity data for 32 and 20 chemicals, respectively, of 55 chemicals reported in the National Response Center database (2000‐2014), and fate and toxicity data for 86 and 103, respectively, of 205 chemicals reported by NOAA (2003‐2014). Modeled environmental concentrations of two hypothetical spills (acrylonitrile, 625 barrels; and denatured ethanol, 857 barrels) were used to demonstrate CAFE's practical application. Most species in the 24 h‐SSD could be potentially impacted by acrylonitrile and denatured ethanol during the first 35 min and 15 h post spill, respectively, with concentrations falling below their HC5s (17 mg/L and 2,676 mg/L) 45 min and 60 h post spill, respectively. Comparisons of CAFE‐based versus published HC5 values for 100 chemicals showed that nearly half of values were within a 2‐fold difference, with a relatively small number of comparisons exceeding a 10‐fold difference. The development of CAFE facilitates access to relevant environmental information, with potential uses likely expanding beyond those related to assessment of spills in aquatic environments.
