摘要: The fluxes of carbon dioxide were determined at the water–air interface using floating chambers connected to an automated nondispersive infrared instrument (NDIR) or a Fourier transform (FTIR). measured in 2002 over 280 sites Canadian reservoirs, rivers, and natural lakes. Mean emissions CO2 old Quebec reservoirs (> 10 years) around 1600 ± 1500 mg CO2/m2/day 735 1125 In young reservoir (5 years old), values higher, with mean 4400 4000 CO2/m2/day. Manitoba, had 3350 2725 lakes 1365 2375 British Columbia, 250 800 500 650 CO2/m2/day, respectively, for Our data suggest that water quality input from terrestrial systems affect waterbodies. results also show older than are comparable rivers terms gross higher would last 6–8 years.
