ECOPHYSIOLOGICAL STUDY ON SOME FRESHWATER ALGAE IN SOME POLLUTED REGIONS OF ISMAILIYA CANAL

Abstract

Lately, there was an increase in the industrial activities and many factories were established on banks of the Ismailiya Canal as one of the main River Nile tributaries in many regions. It is expected that the industrial waste water effluents discharged to lsmailiya Canal from the Gelatine and Colloids; Petroleum Refining; Fertilizers and Chemicals factories and Water Purification Station of Moustorod induce complicated pollution problems.

The present study-work was planned therefore, to follow up change that might take place in total algal count, species composition and its distribution in the Ismailiya Canal water at these regions. The physico-chemical characteristics of water were also analyzed. Sampling was carried out from September, 1996 to August, 1997.

The effect of different concentrations of the industrial wastes of the previous factories and Petroleum on total count, species composition and diversity of algal populations m lsmailiya Canal water cultures was studied in vitro.
