A literature analysis of 158 papers published in international peer-reviewed journals indexed by the Thomson Reuters Web of Knowledge from 1994 to 2013 showed that CO2C emission was significantly lower in free water surface (FWS) constructed wetlands (CW) than in subsurface flow (SF) CWs (median values from 95.8 to 137.0 mg m−2h−1, respectively). In vertical subsurface flow (VSSF) CWs the CH4Cemission was significantly lower than in horizontal subsurface flow (HSSF) CWs (median values 3.0, 6.4,and 4.0 mg m−2h−1, respectively). There were no significant differences in N2O N emission in various Cw types (median for FWS, VSSF and HSSF CWs: 0.09, 0.12, and 0.13 mg m−2h−1correspondingly).The highest... |

use of additives (Mg/P and nitrification inhibitor dicyandiamide - DCD), on nitrous oxide emission during swine slurry composting. The experiment was run in duplicate; the gas was monitored for 30 days in different treatments (control, DCD, Mg/P and DCD + Mg/P). Nitrous oxide emissions rate (mg of N2O-N.day-1) and the accumulated emissions were calculated to compare the treatments. Results has shown that emissions of N-N2O were reduced by approximately 70, 46 and 96% through the additions of DCD, MgCl2.6H2O + H3PO4 and both additives, respectively, compared to the control.
