The following processes and methods have been elaborated: technologies of physical-chemical and biochemical treatment of wastewaters; wastes management; preparation of medical and cosmetic substances; reducing of toxic air emissions; chemical risk assessment methods in the appearance of pulmonary and gastro-intestinal cancer; new processes of biologically active substances preparation; ecological audit; ecological education. The results of his research have been reflected in more than 500 works, both in the Republic of Moldova and abroad, including 36 monographs and manuals.
