| Abstract: |
Multiwavelength spectroscopy is used to study the reddening that af fects the BLR by means of the OI and other permited lines. The values of E(B-V) derived from the OI 1304/8446 agree with those obtained using the Balmer decrement and the HeII lines. They all points to low to moderare amounts of reddening within the BLR. Intrinsic line ratios between the most useful indicators are revisited and give light about the most important destruction mechanisms that may affect them. |
