Abstract
We present measurements of the oxygen abundances in 64 HII regions in 12 LSB galaxies. We find that oxygen abundances are low. No regions wi th solar abundance have been found, and most have oxygen abundances si milar to 0.5 to 0.1 solar. The oxygen abundance appears to be constant as a function of radius, supporting the picture of quiescently and sp oradically evolving LSB galaxies.
