Impact of N,N-dimethylformamide from domestic effluents on river waters.
The impacts of N,N-dimethylformamide (DMF) from domestic effluents on rivers were evaluated. The hourly DMF concentrations in the inflows (0.21-0.52 mug/L in mean) and the outflows (0.18-0.62 mug/L in mean) of two sewage treatment plants did not show any characteristic variations, and DMF was not removed at both plants. The monthly variations of DMF in the outflows of four sewage treatment plants (0.16-0.62 mug/L in mean) and three rivers (0.06-0.11 mug/L in mean) into which the outflows of the plants were discharged did not show any significant variations. The domestic DMF load per person was calculated to be 0.25 mg/d/person. The percent DMF loads of domestic effluents in the rivers were estimated to be below (8%-32%).
