Samples of 226 new improved and 21 indigenous rice (Oryza sativa L.) varieties were collected from the fields in three climatic zones Sri Lanka concentrations 18 trace elements (Li, B, Al, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Sr, Mo, Cd, Ba, Pb Bi) measured giving particular emphasis on Cd As using ICP-MS. The two way multivariate analysis variance (MANOVA) method was employed to identify differences composition among different zones. mean values obtained for both white red Se (36; 25 µg/kg),...
Abstract A chronic Kidney Disease of unknown etiology (CKDu) has emerged with disproportionately high prevalence across dry lowland agricultural communities globally. Here we present the results a prospective cohort 293 patients CKDu in endemic region Wilgamuwa, Sri Lanka, whom measured baseline kidney function and undertook quarterly follow up over 2 years. Well water was primary historic drinking source region, although majority (68%) participants reported switching to reverse osmosis...
Information on the geographic origin of milk is important in determining quality attributes and for economic gain through building brand value associated with origin. Stable isotope signatures trace element concentrations have been increasingly used authentication milk, though information power such technology verifying agroclimatic small continents diverse climatic, environmental conditions, animal management practice scarce. Therefore, main objective this study was to investigate...

Fluoride is a common anion present in natural waters. Among many analytical methods used for the quantification of fluoride waters, potentiometric analysis one most widely because minimum interferences from other ions commonly The requires use ionic strength adjusting buffer abbreviated as TISAB to obtain accurate and reproducible data. In reported literature, higher concentrations strong metal chelating ligands are masking agents generally concentration range 1.0 0.01 M. study,...
Geochemical and isotope data of karstic aquifer systems in the Mulankavil area northwest Sri Lanka were investigated to constrain recharging discharging mechanisms, possible seawater intrusions. The electrical conductivity (EC) groundwater was measured dry (n = 139) rainy 78) seasons assess saltwater intrusions, from which 25 wells selected for detailed geochemical analyses. Water analyses (expressed as δ2HH2O, δ18OH2O) 32 five months. mean EC during both 2,435 μS/cm, higher values coastal...
