Abstract:
The aim of this study is to verify the physico-chemical quality of the waters
and to make an inventory of two species of water birds), the Pink Flamingo and the
Belon Shelduck in the wet zone of Sebkhet El-Mahmel, wilaya Khenchela.
We have, physicochemical analyzes (pH, eclectic conductivity, temperature,
calcium, magnesium, chloride, bicarbonate, sulfates, nitrate) of the water were carried
out in the laboratory EURL SID, in the wilaya of Khenchela
The physicochemical characterization of Sebkha waters has exposed that the
water is cloudy, too salty, the electrical conductivity is high (80300 μS / cm) and the
pH is slightly alkaline (7.95). From these results, it appears that the waters of this
zone are polluted and unfit for irrigation.
As a result, the inventory of the flamingo and shelduck of Belon in the Sebkha
of El-Mahmel during three months, from March to May 2018, revealed to us a very
weak staff.
