Most of -the West German production was agricultural peat, but about one-fifth was consumed as fuel. Other producers ran-king in output in the order named were the United States, 90~ the Netherlands, Canada, and Finland. The combined output of these countries was, however, only 2% of the total. Although fourth in world production, output of the United States was only 0.7% of the world total.

"Preliminary. ' Revised. ' In addition to the countries listed, Austria Canada, Iceland, and Italy produce a negligible quantity of fuel peat. No data are available for East Germany, a major producer. TECHNOLOGY Experimental work conducted at the University of Sherbrooke, Quebec, Canada,2 indicated -that mercury present in waste water can -be removed and recovered quantitatively by treatment with peat. The humic acids contained in peat are known to be good ion-exchange resins, and the studies have shown that contaminated waters can be made virtually mercury-free if treated with moss peat in the presence of a precipitating agent such as sodium sulfide. Recovery of mercury is accomplished by burning the peat containing mercury in the presence of a limited amount of air. Vapors of mercury and sulfur dioxide are eliminated in a scrubbing tower containing limestone and elemental sulfur, and metal- lic mercury can be decanted from the water. Field and laboratory studies conducted at the University of Minnesota 3 have shown that peat soil and various mixtures of sand, calcitic limestone, and peat can be used as filter media to remove significant amounts of phosphorus and organic materials from wastewaters.
