Double and multistation data on meteors from photographic and television records are used. to derive relatlve and absolute numbers of sporadic meteoroids coming to the Earth s vlnicity and their mass accession. Seven different meteoroid populations are dealt with separately inside a mass interval of 2 x 10^ g to 2 x 10^-5 g and their cumulative numbers with decreasing mass determined. This paper is an abstract of more extensive paper, which will be published in Bull. Astron. Inst. Czechosl. In 1988.
