Abstract

fetched live from OpenAlex

environmental studies that assessed the abundance of microplastics in different water columns [8].Release of nanoplastics from drinking water bottles was characterized by SEM, XPS, SPES and µ-Raman Analysis [9].Spherical organic nanoparticles from bottled water were collected effectively through a tangential flow ultrafiltration system [10].Polyethylene terephthalate nanoplastics collected from commercially bottled drinking water were detected with an average mean size of 88 nm; their concentration was estimated to be 10 8 particles/mL by nanoparticle tracking analysis [11].A new study has reported the levels of micro-and nano-particles released in carbonated beverage bottles range from 68 to 4.7×10 8 particles/L, potentially posing health risks to humans.Polypropylene bottles released more particles than polyethylene terephthalate and polyethylene bottles [12].The occurrence of micro-and nano-plastics (with particle diameters from 0.7 to 20 μm) in plastic bottled water has been assessed, and the median concentration was 359 ng L -1 .Polyethylene was the most detected polymer, while polyethylene terephthalate was found at the highest concentrations [13].The content of microplastic and nanoplastic particles in raw water, tap water, and drinking water was analyzed.Plastic particles were found in all water samples, with an average abundance ranging from 204 to 336 particles/L in raw water, from 22 to 33 particles/L in tap water, and from 25 to 73 particles/L in drinking water [14].Pyrolysis gas chromatography-mass spectrometry

Not 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.
