The observations were conducted using the 37-channel Max-Planck Millimeter Bolometer array at the 30-meter IRAM telescope. The continuum emission toward the detected sources was used to quantify the mass of the emitting dust. We combined our observations with data available in literature to construct the spectral energy distribution (SED) of the sources. When the observational data cover a spectral range wide enough, some properties of circumstellar envelopes were derived by comparison with spectra computed using a radiative transfer code. Of the 24 objects in our sample, we detected millimetric continuum emission toward 11 sources. Two other sources were detected at flux level close to 3$\sigma$. The derived circumstellar dust masses range between 0.4 and $24 \times 10^{-4}$ M$_{\odot}$, but these results are affected from the uncertain about the source distances. The parameters derived from the SED fits are consistent with the values characteristic for these kind of object. As confirmed from the flux density extrapolated in the first light channels of the Atacama Large Millimetric Array, such sources would be good targets for future high resolution mapping with the ALMA facility.STAMPAenArticle10.1051/0004-6361:200652642-s2.0-33846829973https://www.aanda.org/articles/aa/abs/2007/05/aa5264-06/aa5264-06.htmlhttp://www.scopus.com/inward/record.url?eid=2-s2.0-33846829973&partnerID=MN8TOARS2007A&A...462..637BFIS/05 - ASTRONOMIA E ASTROFISICA
