Many people say that mineral water is rich in minerals and is more beneficial to human body.
However, mineral water will be polluted by harmful substances such as mercury and cadmium. Recently, Dutch scientists analyzed 68 different brands of bottled mineral water produced in 16 countries, and the results showed that mineral water was more susceptible to the pollution of dangerous microorganisms and bacteria, which contained more pathogenic microorganisms than expected. Although these bacteria may not pose a great threat to people's health, those people's immunity is weak, and bacteria in bottled mineral water may pose considerable danger.
