Distribution of the redshift difference (Δz) between emission and absorption lines of QSOs is "half-gaussian". Also, the quantity Δz increases with increase in emission line redshift (zem). The correlation between the two quantities (Δz and zem) is statistically significant. The interpretation of the results indicate that the co-moving density of absorbing clouds decreases with redshift and that the absorbing clouds are associated with the QSOs rather than completely unrelated intervening material.
