The specific content is this, Urumqi, Xinjiang related reports, living in the human body of E. coli, in special circumstances will become a source of disease-causing infection. Relevant researchers, let E. coli play a “poison against poison” effect, through various ways to remove the divalent mercury ion and selenite ion in the water body, effectively control the pollution of mercury and selenium.
“In the treatment process, the researchers put E. coli bacteria in water containing mercury and selenium, E. coli reduced the high mercury chloride to a precipitate of mercurous chloride, and the other part of the mercury was further reduced to elemental mercury. Here, Escherichia coli may reduce the hite to elemental selenium precipitate and negative selenium ions, which trap mercury ions to form mercury selenide precipitate. When the content of divalent mercury ions reaches a certain amount, it can be removed!”
It is reported that the research was funded by China’s Nature Foundation and other projects, indicating that selenite reducing bacteria, including Escherichia coli, have a greater application prospect in removing mercury and selenium pollution at the same time. The study appears in the journal Science of the Total Environment.
It is understood that mercury is a global pollution, mercury in water mainly exists in the form of divalent mercury, this form of mercury is easy to be converted by organisms into highly toxic methylmercury, eating fish and other aquatic products contaminated by mercury will cause harm to human health! In addition, selenium is an essential element for the human body, but if it exceeds the human body’s tolerance, it is certainly not possible, and the hemite in the water body is a common pollutant. In some areas, the earth’s crust and water bodies contain high levels of mercury and selenium, and the mining of both minerals is prone to contaminate surrounding areas at the same time, so monitoring and treatment of mercury and selenium in water is a key link.
As for monitoring the indicators in the water, it will involve the water quality online monitor, and the corresponding instrument will be used according to the specific parameters. Hangzhou Modi-Tech is a water quality online monitoring instrument manufacturer, the main products are: E. coli online analyzer, mercury in water online analyzer, total selenium online analyzer, heavy metal in water online analyzer and other different parameters of the monitoring equipment.
