SAPROBIENSYSTEM 



European system of classifying organisms 

 according to their response to organic 

 pollution in slow moving streams. 



1. Alpha-Mesosaprobic Zone - Area of active 

 decomposition, partly aerobic , partly 

 anaerobic , in a stream heavily polluted 

 with organic wastes. 



2. Beta-Mesosaprobic Zone - That reach of a 

 stream that is moderately polluted with 

 organic wastes. 



3. Oligosaprobic Zone - That reach of a 

 stream that is slightly polluted with 

 organic wastes and contains the mineralized 

 products of self-purification from organic 

 pollution, but with none of the organic 

 pollution remaining.
