Chronic toxicity of energetic compounds in soil determined using the earthworm (<i>Eisenia andrei</i>) reproduction test
Bibliographic record
Abstract
Abstract Earthworm survival tests are commonly used in terrestrial ecotoxicology to assess the toxicity of compounds in soil. Earthworm (Eisenia andrei) reproduction tests were used to assess the sublethal and chronic effects of 2,4,6-trinitrotoluene (TNT) and 1,3,5-trinitro-1,3,5,7-triazacyclohexane (RDX). Effects on reproduction parameters (total number of cocoons, number of hatched cocoons, number of juveniles, juvenile biomass, and hatchability) were measured in TNT- and RDX-spiked artificial soil. For TNT, the lowest-observed-effect concentration (LOEC) was 110 mg/kg dry soil, and the no-observed-effect concentration (NOEC) was 55 mg/kg. For the RDX-spiked soil, the LOEC was 95 mg/kg dry soil, and the NOEC was &lt;95 mg/kg. The growth of adult worms was also reduced when exposed to TNT-spiked soil at the highest tested concentration (881 mg/kg dry soil). Taken together, data analysis showed that the number of juveniles was strongly correlated with the number of cocoons but poorly correlated with the growth of adults. This information could permit one to optimize the application of the Eisenia sp. reproduction assay when used as a sublethal effect assessment tool for TNT- or RDX-contaminated soils.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
