ABSTRACT
The petroleum pollution in the western regions are at
its maximum in El-Sal1um Bay. Comparatively rich fish catch
is found in the Bay. Abu-Oir Bay was surveyed to trace
the influence of pollution upon its ·water’s chemical
characteristics and fishes. About 221 X 106 ton/year of
chemical compounds are estimated as discharged pulp-mill
wastes in the Bay. The decline of its fish stock is clear.
The coastal regi ons north to El-Boro 11 us shores is found
containing surplus 1500 tons of P ions and 90 X 103 ton
of COD. The corresponding fish catch is found stable and
may reach 300 ton/year.
