Chemical solvents, sulfuric acid, degreasing oil and odor are harmful to human body. ! Please answer in detail! !

Some sulfuric acid is not very big, because the human body itself has sulfate. Tofu contains a lot of calcium sulfate, and spinach also contains a chemical solvent containing ferric sulfate. It's best not to touch it, because it contains many impurities and heavy metals, which can't be discharged by human body in time, which will cause enrichment in the solvent. There are a lot of phosphides in it, which will endanger organ aging and affect intellectual development. Chemical solvents will be enriched, which is harmful to the fetal body function.
