The formation of complexes between tebuconazole (Teb) and cadmium in simplified model solutions as well as soil solutions was studied using electrospray ionization mass spectrometry. Teb and cadmium form two types of complexes with the general formulas [Cd(Teb) (n) ](2+) (n = 1-4) and [CdI(Teb) (m) ](+) (m = 1-3), where iodine corresponds to the counterion used. The most intense Teb/cadmium complex is [CdI(Teb)(2)](+), and the most stable one is [Cd(Teb)(Teb - H)](+). Another detected complex, the dication [Cd(Teb)(4)](2+), was considered as the origin complex for the iodine-free complexes and was found in a sample prepared from forest soil solution naturally contaminated with cadmium ions.
