PLANT UPTAKE STUDY: THE HYPERACCUMULATING AND REMEDIATING POTENTIAL OF THREE PLANT SPECIES
Bibliographic record
Abstract
This thesis presents the results of investigations into the ability of cattail (Typha latifolia), willow (Salix spp.) and sedge (Carex lenticularis) to hyperaccumulate selenium and sulphate in contaminated water at an active coal mine site in northeastern British Columbia. The plants were cultivated in containment bins which were irrigated using water collected from the mine settling ponds containing elevated levels of selenium and sulphate. Water from an un-impacted creek near the mine site was used for the control bins. The bioconcentration factor (BCF), biological accumulation coefficient (BAC) and biological transfer coefficient (BTC) data obtained suggested the plants could be used for phytostabilization and phytoextraction of selenium, however the plants were not hyperaccumulators. Additional studies including the use of chelating agents such as EDTA which have been shown to increase metal translocation into plant tissue thereby improving overall phytoextraction would be beneficial to areas in Northern Canada with short growing season.

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.
