摘要
It has recently become possible to measure directly the abundances of several chemical elements in a variety of environments at redshifts up to z similar or equal to 5. In this review I summarize the latest observations of Lyman-break galaxies, damped Ly alpha systems and the Ly alpha forest with a view to uncovering any clues that these data may offer to the first episodes of star formation. The picture that is emerging is one in which the Universe at z = 3 already included many of the components of today's galaxies; even at these early times we see evidence for Populations I and II stars, while the 'smoking gun' for Population III objects may be hidden in the chemical composition of the lowest density regions of the intergalactic medium, yet to be deciphered.
