The 3mm transitions to CO, 13Co, CS, HCO+ and HCN have been observed toward the compact HII regions in W58 using the 14m Daeduk Radio Telescope(DRT). Some of the observed lines show high-velocity wings resulted from outflowing materials of the compact HII regions. We derive the beam averaged column densities of the observed species and compare their relative abundances. The HCO+ abundance appears to be smaller by about an order of magnitude than those of 'typical' quiet molecular clouds. CS may be a good reference molecule in comparing relative abundances in different physical conditions.
