Arsenic sometimes naturally occurs in water and can be found in public and private water supplies. Mining operations, semiconductor manufacturing, use of wood preservatives are some of the ways water can be contaminated with this poison. If you have a private well you should test for arsenic at ...
Field test kitElevated exposure to arsenic disproportionately affects populations relying on private well water in the United States (US). This includes many American Indian (AI) communities where naturally occurring arsenic is often above 10 mu g/L, the current US Environmental Protection Agency ...
I immediately ceased drinking the well water and they are only drinking bottled water now. How soon would the symptoms go away if they were not drinking it anymore (for example stomach pain, nausea, etc). I ceased all family drinking of my well water. As soon as I did, within 48 hours...
A comparison of field and laboratory measurements of in groundwater of Araihazar, Bangladesh, indicates that the most widely used field kit correctly determined the status of 88% of 799 wells relative to the local standard of 50 microg/L As. Additional tests showthatthe inconsistencies, mainly ...
Expanding Quantification of Arsenic in Water to 0 μg L −1 with a Field Test Kit: Substituting 0.4% M/V Silver Nitrate as the Colorimetric Reagent; Employing Digital Image AnalysisThis study confronts the questionable reliability and accuracy of field test kits distributed globally to ...
Naturally occurring arsenic, typically harmless in its natural state, can undergo transformation into inorganic arsenic, thereby contaminating groundwater sources used for drinking or irrigating crops. The accumulation of arsenic from one trophic level to another level, depends not only on the total ars...
1 were used for acidic digestion. The filtration of the digested samples was accomplished using Whatman paper (pore size-0.45 µm). Then the volume of digested solution was made up to 50 mL to proceed for selenium and arsenic analysis. The water samples were also collected in plastic ...
Cell viability was detected using a CCK-8 kit (Beyotime, Shanghai, China) based on instructions provided by the manufacturer. Cells were cultured in 96-well plates and exposed to different concentration of genistein (0, 10, 20, 40, 80 μM) (Sigma, St. Louis) for 24 h. At the end ...
An arsenic exposure study (50 ppm sodium arsenite in drinking water for two weeks) revealed no significant variation in microbial diversity (Li et al., 2019). Accordingly, to induce perceived disturbance on the gut microbiome, we set the concentration of tAs (CtAs) to 30 ppm for the test ...
All plant samples were thoroughly washed with tap water to remove surface soil and carefully washed with distilled water and ultra-pure water, respectively. Samples were oven-dried at 65 °C for 72 h to a constant weight and ground into a fine powder with stainless steel mill for analysis ...
