Scientific paper
The present investigation takes into account studies reported by various authors mainly during the last 15 years. In describing the chemical composition of a material, use is made of the enrichment coefficient (EC). The EC relates the concentration of an element in the considered material to its concentration in the earth's crust. High EC values for 'volatile' and 'fusible' elements (Se, Br, As, Hg, Pb, Zn, Ag, I) found in global aerosols and in the Tunguska comet point to a cosmic origin and, mainly, cometary derivation for the material in the aerosols. It appears, therefore, that at the current time period normal meteorites are not the primary source of cosmic dust on earth. The external layers of the earth formed under conditions of systematic inflow of cometary material represent differing compositions of cometary and meteoric matter.
