Scientists learned to neutralize dangerous natural poison using germs 02:42

Chinese scientists from Khujun Agricultural University developed an advanced approach to detoxification of land with arsenic contaminated land. Arsenic oxidizer found that interaction with Getit by Arsenic and Mineral significantly accelerated the transformation of toxic arsenite. [As(III)] In a less harmful arsenate [As(V)]. The results of the study were published there magazine Eco-environment and health (EEH).

Arsenic, especially in the form of arsenite [As(III)]It poses a serious threat to human health and ecosystems. It easily penetrates water and soil, which makes it dangerous for agriculture and drinking sources. Toxically, the transformation of AS in a less mobile and less harmful way is an important step in the cleaning process.

Scientists have worked with bacteria to interact with the oxidizing arsenic (SY8 strain) Gatit, a common iron mineral. Although the door suppressed the growth of bacteria, it was revealed that (III) significantly increased its oxidation capabilities. This is accelerated due to the formation of hydroxyl radicals (· OH) during the reactions of Fenton, which is catalyzed by the interaction of hetite and bacteria.

In addition, the addition of humic acid, a natural organic compound, improved adsorption on the surface of the arsenic mineral and reduced the surrounding mobility.

The study showed that oxidation of AS (III) occurs in the most effective neutral or mild alkaline conditions. This emphasizes the importance of monitoring the pH level in the development of soil breeding strategies.

The results offer new opportunities for cleaning dirty soils, especially in agricultural and industrial regions. This discovery can form the basis of the development of economically effective and environmentally friendly soil recovery methods.
