Temsah lake is considered one of the wild life features
in Egypt in general and in the Suez Canal region in particular. Through
field experiment, concentrations of some pesticides which are used around
the area, were monitored in the tissues of some birds of prey (wild birds),
some species of algae, fish and crustaceans. The results obtained revealed:
(1) The presence of some Organochlorines (OC) in the tissues of many of
the tested birds represented in (DDE, Heptachlore, HCH, Dicofole). (2)
The presence of high residues of Organophosphorus (OP) pesticides represented
in malathion and diazinon in most of the tested birds. But they were not
detected with high levels in any of fish, crustaceans or algae. (3) The
presence of high concentrations of (OC) compounds in the tissues of algae,
crab, mullet and some birds (moorhen-cormorant and gulls). Meanwhile,
none of those compounds was detected in the water samples. (4) The presence
of high levels of all detected pesticides in the tissues of crab makes
it the very acceptable bioindicator to mirror the pollution of the lake,
then followed by algae. (5) Pollutants can be transferred through the
food chain which causes biomagnification of them in the bodies of the
higher organisms in the food chain. It could be concluded that implementation
of the environmental management practices in Lake Temsah is still needed
to protect these ecosystems from more pollutions which could affect human
health and environment.

kusuma zaenal: I interest with yours abstract.
I want to detect profenofos in fish at lake.
How about the measurement of the pesticide in fish tissue.
Could I have the full text of this journal.
Thank you very much.
