Using the Modified Semiempirical Method we have calculated the electron-impact widths for four singly and doubly ionized zirconium UV lines of astrophysical importance. Using the SYNTH and ATLAS9 codes for stellar atmospheres similar to that of the HgMn star χ Lupi we have synthesized the line profiles and found equivalent widths for these lines. The influence of the Stark broadening effect on abundance determination and its contribution to the so-called ``zirconium conflict'' are discussed. .
