USING OF Porcellio sp. AS A BIOINDICATOR TO MUEASURING THELEVEL OF SOME HEAVY METAL POLLUTION IN BAGHDAD CITY

Abstract

The aim of this study is to estimate the pollution levels of heavy metals by using the
genus porcellio sp.as a bioindicator to this pollution.
Four experimental sites in Baghdad were selected (Jadrya, Al-sadr, Al-dura and Algazalya).
the genus individuals were take from the soil of these places and dried then
analyzed by the Absorption Sepctrophotometry. Seven heavy metals measurd they
includes (Pb ,Cu ,Fe ,Mn ,Ni ,Cd and Co).
The results showed that there was a pollution in these places and the higher levels in
Jadrya were in (Cu 8166±0.33 , Mn 5963±0.44 , Cd146±0.08) μg/gm, in Al-sadr
city were in (Fe 99801±1.15, Co 220±0.15) μg/g in Al-dura was in (Ni416±0.08)
μg/g and in Al-gazalya were in (Pb6966±0.88 , Co233±0.12) μg/g .This pollution of
heavy metals was a natural result because of the traffic activity and the increasing of
the car numbers which still using the lead gasoline and this caused big troubles to
the environment, dangerous to the human.Beside the human activities, recent the green zones is important in decreases the damages of heavy metals on the
environment.
