Low load, shallow HSSF CW emitted 440 mgCH4/m2*d on average. Slightly higher CO2 and lower CH4 emissions were found in planted units. No significant differences in emissions between units with different macrophytes. Temperature determined CO2 and CH4 emissions for all units except Juncus effusus unit. Emissions can be estimated from methanogenic activity assays of accumulated solids.
