Comments P.129 left column bottom paragraph: "Just as in the case of natural waters, [investigators] can speak of a chemical oxygen demand (COD) which is herewith defined as the annual oxygen consumption by reductive atmospheric compounds. Holland (primary source) gives a COD value of 3.1 x 10^12 mol O2/yr for the volcanic gases consuming oxygen."
