The AA. compare particulate organic carbon (POC) measurements derived from 2 commonly-used techniques; a simple combustion and loss-on-ignition (LOI) technique, and an oxidative–combustion and carbon dioxide (CO2) detection technique. The techniques were applied to water samples collected from 10 contrasting reference-condition, temperate river ecosystems. The POC measurements derived from the LOI technique were up to 16 times higher (average 4 times higher), than those derived from the oxidative–combustion and CO2 detection technique. This difference was highly variable both across the different river ecosystems and within each river ecosystem over time, suggesting that there is no simple way of converting the mass measured by LOI to estimates of fluvial POC. The results suggest that oxidative–combustion and CO2 detection techniques are preferential for quantifying fluvial POC
