However several individual component tests are included and the results were always below the LOD. Test methods were mainly US EPA 8260b. iii Chlorine dioxide measurements are taken BEFORE seawater entry into condensers and it s difficult to measure at outfall due to the nature of the pollutant, given its instability. ClO2 concentration at the main outlet will be well below any equipment resolution level and annual concentration and quantity discharge values are therefore considered as nil.
