Plant Cell Responses to Naphthenic Acids and Acid Extractable Organics Derived from Oil Sands Tailings Pond Water
Bibliographic record
Abstract
Mining of bitumen from the oil sands located in Alberta, Canada results in the production of oil sands process-affected water (OSPW). Naphthenic acids (NAs) are a constituent of the acid extractable organic (AEO) fraction isolated from OSPW. Detrimental phenotypic responses are apparent in plants exposed to NAs and AEO fraction. The aim of this thesis is to characterize the responses of plant cell structures after treatment with NAs and AEO fraction. Disruption to microtubules, actin filaments, mitochondria, peroxisomes, Golgi bodies, ER, and cell membranes was observed in onion epidermal cells and Arabidopsis thaliana root epidermal cells. Increasing reactive oxygen levels induced by NA and AEO exposure, and decreased cell viability after AEO exposure was also observed. This research represents the initial characterization of organelle and cytoskeletal responses after NA and AEO exposure in eukaryotic cells, and highlights the potential of cytoskeleton and organelle markers as a biosensor for OSPW toxicity.

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.
