STYGOTOX: A Quality‐Assessed Database of (Eco)Toxicological Data on Stygofauna and Other Aquatic Subterranean Organisms.

We have compiled the toxicity data on stygofauna and other aquatic subterranean organisms in one (eco)toxicological database. A total of 46 studies were found, containing 472 toxic endpoints covering 43 different stressors. These compounds were tested on subterranean organisms from four phyla, 12 orders, 24 genera, and 55 species. The studies included were published between 1976 and December 2023 using fauna collected in 13 different countries. The suitability of the studies was assessed to indicate the completeness of reporting and their suitability for use in hazard and risk assessment. This compilation provides a valuable source of data for future development of toxicity testing protocols for groundwater organisms, and to support decision‐making, ecological risk assessments and the derivation of water quality criteria for the protection of groundwater ecosystems.
