Summary:Measurements in 1981 of the He content of the Earth's lower atmosphere have given a value of 5.222 + or - 0.017 ppm by volume. This value, obtained by isotope dilution MS, is 0.3% lower, but in essential agreement with the currently accepted value of 5.239 + or - 0.004 ppm determined by Glueckauf in the 1930's. A consideration of processes that could have altered the He concentration since the 1930's indicate that the concentration could have increased measurably due to release of He by natural gas production. Possible net He loss from the atmosphere is, however, not readily quantifiable. (Authors' abstract) [J.M.H.]
