Rhine nitrate

Fig. 6 Concentration ranges (5%, 50%, and 95% percentiles) of nitrate in six glacier streams (Gla), two alpine streams (Ver, Cal), one prealpine stream (Erl), three alpine rivers Rhine (Rhi), Rhone (Rho), and Ticino (Tic) and the midland river Thur (Thu)...

Blom was the first to demonstrate, in 1928, the formation of HA by an unknown mixture of bacteria which utilized nitrate as their sole nitrogen source to produce ammonia , an observation substantiated by Lindsey and Rhines who generalized this reaction to a diverse set of microorganisms capable of producing NH3 by reduction of both nitrites and nitrates. The mechanism of the 6-electron reduction of nitrite to ammonia (i.e. conversion of the [N + 02] species to by bacterial cytochrome c nitrite reductase...

My narrative (in chapter 5) followed Bosch almost to the end of the World War I, when he organized the expansion of ammonia synthesis and nitrate production at Oppau and the construction of a new ammonia plant at Leuna. Shortly after the war s end, in December 1918, Bosch was delegated to Spa, and in March 1919 to Versailles, as the representative of German industry in the armistice and peace treaty delegations. After his return from France he became the chairman of the BASF board, and in that capacity he had to deal with the worst disaster in the company s history, an explosion at Oppau that caused more than 500 fatalities and destroyed the homes of more than 7,000 people in September 1921. In May 1923 Ludwigshafen was occupied by French troops, and Bosch, who fled across the Rhine, was sentenced in absentia for his refusal to cooperate with French authorities.
