| 520 | 3 |a"The seasonal cycles of dissolved nitrogen forms in Hamilton Harbour, an embayment of Lake Ontario receiving treated effluents from a population of over 400,000 and industries, appear to be deformed by the excessive loadings of ammonia which possibly inhibit the nitrification process, particularly the formation of nitrate. The intermediate process (i.e., the production of nitrite) appears to be more responsive and less inhibited. While concentrations of ammonia vary between overload levels of 4-10 mg/L (as N) to values close to zero, the temporal variability of nitrate concentrations is less pronounced (1.5-2.5 mg/L as N). Algal uptake is assumed to be the major factor governing the ammonia regime rather than nitrification, which does not appear to be proportional to ammonia losses and may be inhibited by extremely high ammonia levels"--Abstract. |
