الملخص EN

Seeveral soil and water smples were collected from different sites, in Daher Aljabel (Sowaida province).

These sample s were analysed for studing some physio- chemical properties, as well as for the possibility of pesticides residue in the soil and water.

The result showed that: The studied soil s have aclayey texture, CEC moderate to rather high, almost neutral PH, the real and bulk density are within the normal range, absence of CaCO3, and O.M.

content is moderate.

Also, the results of water analysis show: aneutral PH, and very low salt content.

The results showed, the absence of any residue of phousphour pesticides, because this pesticides un stable in soil.

There are alow and different quantity of chloro pesticide, particularly in the sub surface layer.

The hightest accumulation was in the area of Alkafer 757.2 ng/ml of Endrin pesticide and 179 ng/ml of Dieldrin pesticide.

In the water samples, these concentration of pesticides was in the very lower limits 7- 8 ng/ ml in the three sites.
