| Abstract |
Nitrification in streams of the western Upper Peninsula of Michigan was studied. The maximum nitrate content observed was 3.7 mg/l-N which occurreduring the summer. About 92 percent of the streams contained less than 1.0 mg/l nitrate nitrogen, and 40 percent showed no detectable nitrate concentration at all. The basins of streams with greater than 1.0 mg/l-N nitrate content were seen to include villages or rural communities. Samples of a stream known to receive municipal wastes were incubated under controlled temperature conditions and oxygen uptake was monitored. Addition of 2 mg/l ammonia nitrogen increased the first order BOD rate constant, ultimate nitrate concentration and the percent BOD attributable to nitrification. (Author) |
