Distillation. Distillers are a countertop water treatment solution that reduce up to 99.99% of all water impurities, including arsenic. To use a water distiller, add water to the boiling chamber, and switch the machine on. The water will evaporate, before passing through a corridor and condensing into a clean carafe.

After 168 hours of incubation, 93.13% removal of Cd and 94.25% removal of As were observed. Microstructural analysis proved the presence of calcium carbonate in the form of calcite, confirming removal of cadmium and arsenic by microbially induced calcium carbonate precipitation (MICCP) to be promising technique for water decontamination.

The removal of cadmium, arsenic, and lead from drinking and irrigation water is a recurring challenge, especially in developing countries. Cost considerations can make it expedient to use local materials, produced in agricultural or industrial operations, as adsorbents for these toxins. Performance of these materials may not always be optimal ...

Cadmium (Cd) and arsenic (As) accumulation in soils is a problem in some places. A national survey in China [], for example, revealed that Cd content in 7.0% of sampling sites exceeded the national standard; for As content it was 2.7%.Because of their toxic and carcinogenic nature, Cd and As in the soil poses a threat to environmental …
