أجري البحث بهدف التحري عن الملوثات المعدنية ( الرصاص, الكادميوم, الزرنيخ), و التي تنتقل من مياه الريّ إلى العديد من أنواع الخضار التي تروى بها و مقارنة مدى التلوث حسب مصدر الريّ (مياه صرف صحي معالجة، مياه آبار)، و نوع الخضار (خضار ثمرية، درنية)، و طريقة الريّ المتبعة (الريّ السطحي، الريّ الحديث).
The research was conducted in order to investigate the metal
contaminants (lead Pb،cadmium Cd ، arsenic As), which moves
from irrigation water to many types of vegetables which irrigated
from it,and compared the extent of pollution by irrigation source
(treatment sewage، wells water), and by vegetable type
(Vegetables, fruit plants, tuberous), and by the irrigation method
used (surface irrigation ، modern irrigation).
