The abundances of a few light elements in the atmospheres of halo dwarfs are redetermined on the basis of literature data reanalysed in an homogeneous way. It is shown that the scatter of the resulting Mg and Al abundances is strongly reduced and that no discrepancy remains between the abundances deduced from blue and red lines. Mg, Si and Ca show constant overabundances while the Al overdeficiency seems in agreement with the predictions of explosive carbon burning.
