Numerous chemicals have toxic effects on the human body. Therefore, every substance should be treated as if it were toxic. The greatest accuracy and cleanliness should be observed during laboratory work. In accordance with the Environmental Code’s substitution principle (SFS 1998:808, Chapter 2, Section 4), chemical products that are hazardous to health and the environment must be substituted with
