Research into Ceiling Dust

Jeffrey Davis is a research student from Macquarie University (resides at CSIRO) who has been studying ceiling dust for the past 4 years. His research involves looking at 35 house sites across the Sydney urban environment, where homes have been selected from, heavy industrial, industrial, urban, non-industrial and rural locations. Some of the methods and techniques Jeff has been using within his research include; microscopy and mineralogy of the ceiling dust, size fractionation from 4mm to <2.5 microns, x-ray diffraction and chemical analysis for 56 elements. The 56 elements analysed are:

 

silver (Ag) aluminium (Al) arsenic (As) gold (Au) barium (Ba) beryllium (Be) bismuth (Bi)
bromine (Br) calcium (Ca) cadmium (Cd) cerium (Ce) chlorine (Cl) cobalt (Co) chromium (Cr)
cesium (Cs) copper (Cu) europium (Eu) iron (Fe) gallium (Ga) hafnium (Hf) mercury (Hg)
iridium (Ir) potassium (K) lanthanum (La) lithium (Li) lutetium (Lu) magnesium (Mg) manganese (Mn)
molybdenum  (Mo) sodium (Na) niobium (Nb) nickel (Ni) phosphorus (P) lead (Pb) rubidium (Rb)
sulfur (S) antimony (Sb) scandium (Sc) selenium (Se) silicon (Si) samarium (Sm) tin (Sn)
strontium (Sr) tantalum (Ta) terbium (Tb) tellurium (Te) thorium (Th) titanium (Ti) thallium (Tl)
uranium (U) vanadium (V) tungsten (W) yttrium (Y) ytterbium (Yb) zinc (Zn) zirconium (Zr).

Presently the results of this research are very near publication and will soon be released [as long as funding becomes available].
