| Abstract |
Several indexes of chemical and biological water quality are compared. A new chemical index and a modification of the saprobic index based on diatoms are proposed. For the drainage basin of the Samson, chosen for its diversity, the estimation resulting from the simultaneous use of our new indexes is better than the other methods. Owing to the direct reaction to organic pollutants used as nutrients by some species, the diatoms give more precise and valid indications than the benthic macroinvertebrate communities which are more influenced by substrate or current conditions. |
