Decharat and Pan-in 2020 - Pb and Cd in school drinking water in Thailand
Decharat and Pan-in measured Pb and Cd in school drinking water in Nakhon Si Thammarat Province, Thailand. The source is routeable because it separates bottled water, tap water, filtered tap water, and raw water and gives concentration ranges for Pb and Cd. It is especially useful for water-filter context because filtered tap water is analyzed as a distinct matrix.
Key numbers
- n=146 water samples from 44 primary schools, collected between 1 September 2018 and 31 January 2019.
- Bottled water: Pb ND-0.0180 mg/L and Cd ND-0.0013 mg/L.
- Tap water: Pb ND-0.0250 mg/L and Cd ND-0.0042 mg/L.
- Filtered tap water: Pb ND-0.005 mg/L and Cd ND-0.0021 mg/L.
- Raw water: Pb ND-0.0400 mg/L and Cd ND-0.0049 mg/L.
Methods (brief)
Pb and Cd concentrations were determined by graphite furnace atomic absorption spectrometry. The study then evaluated child health risk from school drinking-water use.
Implications
Certification: bottled-water and water-filter context for Pb/Cd ranges. Courses: useful example of filter-state matrix separation. App: supports a Thailand school-water jurisdiction flag and filtered-vs-unfiltered distinction.

Verification notes
All concentration ranges, sample count, dates, and matrix labels were taken from the PDF abstract/first page. Units are mg/L and must not be silently converted without logging.
