The BenthoTorch for Rivers

16 May 2011

Nutrient enrichment (eutrophication) in rivers is a big problem but more difficult to measure than in lakes and dams.  This is because the algal response occurs as attached algae, on rocks or sediments or other surfaces. The quickest and easiest way to measure this is by using the bbe BenthoTorch.
This instrument is very similar to its sibling, the AlgaeTorch, but goes a step further: this unit can measure the relative concentrations of chlorophyll from green algae, blue-green algae and diatoms.  Results are available immediately, in the field, from living algae.  As simple as pointing a torch at a rock!
Further details about this and other bbe products are available from www.dhec.co.za
