ESO 546-G34: The most metal poor LSB galaxy?
  We present a re-analysis of spectroscopic data for 23 HII-regions in 12 blue,
metal-poor low surface brightness galaxies (LSBGs) taking advantage of recent
developments in calibrating strong-line methods. In doing so we have identified
a galaxy (ESO 546-G34) which may be the most metal-poor LSB galaxy found in the
local Universe. Furthermore, we see evidence that blue metal-poor LSBGs,
together with blue compact galaxies (BCGs) and many other HII galaxies, fall
outside the regular luminosity-metallicity relation. This suggests there might
be an evolutionary connection between LSBGs and BCGs. In such case, several
very metal-poor LSBGs should exist in the local Universe.
