We conducted a study to examine seasonal changes in residential dust lead content and its relationship to blood lead in preschool children. We collected blood and dust samples (floors, windowsills, and carpets) to assess lead exposure. The geometric mean blood lead concentrations are 10.77 and 7.66 microg/dL for the defined hot and cold periods, respectively (p < 0.05). Lead loading (milligrams...
The current study was applied in Al-Zafaraniya area southeast of the capital Baghdad from October 2021 to April 2022. This is evaluate some heavy elements (Cd, Co, Cu, Fe, Pb, and Mn) street, storm, suspended dust. Four sampling sites were selected, codes A, B, C, D given represent industrial activity sites, service workshops, business activity, residential areas. results showed that concentrat...
We present Far Ultraviolet Spectroscopic Explorer (FUSE) observations of interstellar molecular hydrogen (H2) in two Galactic high-velocity clouds (HVCs). Molecular hydrogen absorption is detected in the Magellanic Stream (abundance ∼ 0.3 solar) toward the Seyfert galaxy Fairall 9 in the lowest three rotational states (J = 0− 2) at vLSR = +190 kms , yielding a total H2 column density of log N(H...
The present paper deals with the assessment of heavy metals in soil and roadside dust around Misurata City Centre and industrial areas/roads in the period of October 2011-May 2012. The levels of Pb, Fe, Zn, Ni, Cd, Cr, and Cu in settled dust samples collected near small streets, playgrounds, gas stations and main streets in the Misurata Area have been determined by inductively coupled plasma at...
We investigate the effect of line of sight temperature variations and noise on two commonly used methods to determine dust properties from dust continuum observations of dense cores. One method employs a direct fit to a modified blackbody SED; the other involves a comparison of flux ratios to an analytical prediction. Fitting fluxes near the SED peak produces inaccurate temperature and dust spe...
BACKGROUND Effects of the World Trade Center (WTC) disaster on children's respiratory health have not been definitively established. OBJECTIVE This report describes respiratory health findings among children who were < 18 years of age on 11 September 2001 (9/11) and examine associations between disaster-related exposures and respiratory health. METHODS Children recruited for the WTC Health ...
We present the first results from a new 250, 350, and 500μm Galactic Plane survey taken with the Balloon-borne Large-Aperture Submillimeter Telescope (BLAST) in 2005. This survey’s primary goal is to identify and characterize high-mass proto-stellar objects (HMPOs). The region studied here covers 4 deg near the open cluster NGC 6823 in the constellation Vulpecula (l = 59). We find 60 compact so...
The components and quantities of atmospheric dust fallout have been reported to be the pollution indicator of large urban areas. The multiplicity and complexity of sources of atmospheric dusts in urban regions has put forward the need of source apportionment of these sources indicating their contribution to specific environmental receptor. The study presented here is focused on investigation of...
