The chemical abundances of metal-poor stars provide a wealth of information on various stages of chemical evolution of the Galaxy. In the past, chemical abundance studies of metal-poor stars were limited to giants in dwarf spheroidal galaxies and dwarfs/giants in the Milky Way. In this work I explore the possibility of studying the Galactic chemical evolution using horizontal branch stars, since they are photometrically bright and commonly found in the Galactic disk and halo. I will show the results of this study and present a new method to analyze the spectra of RR Lyrae stars throughout the pulsational cycle.
