Scientific paper

The effects of a temperature range on the effective emissivity of grains have been considered. It is found that the use of the color temperature as the physical temperature of grains for the interpretation of middle-infrared data (wavelength of about 10 microns) leads to serious underestimates of the dust mass inside H II regions (typically by a factor of 20). As a consequence, the corrected abundance of dust relative to the gas turns out to be similar to that of the interstellar medium. It also agrees well with the determinations obtained from far-infrared data.
