Cadmium Toxicity Towards Marine Diatom Thalassiosira sp. and its Alteration on Chlorophyll-a and Carotenoid Content
Bibliographic record
Abstract
Cadmium is one of the non-essential metals that have toxic effects on aquatic organisms, including diatoms. Diatoms play significant important roles in the aquatic environment, hence, the presence of cadmium will have a significance growth inhibition to its abundance. In this paper, we tried to clarify the effects of cadmium on growth, chlorophyll-a and carotenoid contents of the diatom Thalassiosira sp. Growth inhibition of the phytoplankton was determined following exposure for 96h to several different concentrations of cadmium solutions in an experiment adapted from ASEAN-Canada CPMS II. Our work shows that IC50 of growth and chlorophyll-a was around 0.32 mg/L and 0.914 mg/L, respectively. In addition, the Lowest Observed Effect Concentration (LOEC) and No Observed Effect Concentration (NOEC) were 0.18 mg/L and 0.1 mg/L, respectively. In conclusion, cadmium inhibits the growth, as well as the photosynthetic pigment contents of Thalassiosira sp.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
