ABSTRACT
There is a bidirectional interactive relationship between heavy metals and intestinal microorganisms. Single exposure to common heavy metals (Cd, Cr, As, Pb, etc.) may cause intestinal microecological damage and related diseases by losing the diversity and relative abundance of intestinal microorganisms. However, heavy metals in the environment are usually mixed exposure and an overall toxic effect is presented. Published studies have suggested a synergistic effect between most heavy metals, so the impact of mixed exposure on intestinal microorganisms is expected to be more significant than that of single exposure. Intestinal microorganisms are the first line of defense against heavy metals entering the body, and can reduce inflammation and oxidation caused by heavy metals via changing protein synthesis, intestinal PH, enzyme activity, etc. At the same time, the colonization of oral probiotics in the intestinal tract has a significant detoxification effect on heavy metals entering the body through synergy with intestinal microorganisms, which can promote the elimination of heavy metals, reduce the production of oxides and inflammatory mediators, reverse the changes in the relative abundance of intestinal microorganisms, and then reduce the damage of heavy metals to intestinal microecology. Therefore, probiotics may have better prospects than traditional heavy metal antidotes. In the future, more in-depth research on the mechanism of bidirectional interactive relationship between heavy metals and intestinal microorganisms is needed to provide new ideas for clinical heavy metal detoxification.
