أجري البحث بهدف التحري عن أهم الجراثيم الممرضة (جراثيم الكويفورم، الإشريكية القولونية، السالمونيلا)، و التي تنتقل من مياه الري إلى العديد من أنواع الخضراوات التي تروى منها.و مقارنة مدى التلوث حسب مصدر الري )(مياه صرف صحي معالجة، مياه آبار)، و حسب نوع الخضار (خضار ثمرية، درنية)، و طريقة الري المتبعة (الري السطحي، الري الحديث).
The research was conducted with the aim of investigating in the most important pathogens (coliform_ E.coli_ Salmonella), which moves from irrigation water to many types of vegetables which irrigated from it. And compared the extent of contamination by irrigation source (treatment sewage, wells), and according to the type of vegetable (fruit plants, tuberous vegetables), and the irrigation method(surface irrigation, modern irrigation).

The study was conducted in 2011 on 6-years-old citrus trees "Washington navel
141". It contained four treatments with three replicates for each treatment. The results
showed that:
The wastewater treatments showed superiority on the control in the
number of
vegetative growth and its length.
The number of inflorescence buds, was increased in the second treatment (irrigation
with 50% treated wastewater +50% normal water) (5. 37) which dominated the other
treatments.
The weight of fruit was affected by treated wastewater irrigation. Second treatment
(irrigation with 50%treated wastewater+50 % normal water) was better than the control
treatment. It was increased by (308. 3 g) compared to (259. 5 g) for the control treatment.
Fruit yield production per tree, was increased by second treatment (irrigation with
50% treated wastewater+50 % normal water) (28. 9kg) compared to (15. 3kg) for the
control.
Treated wastewater irrigation had positive effects in the quality of fruit
(Total sugar %), (T. S. S %) and the coefficient of maturity were increased in second and
third treatment compared to other treatments, while (T. A %) was decreased in all
wastewater treatments.

This investigation was carried out during 2011–2012 season at the
biotechnology department\General Commission for Scientific Agricultural
Researches in order to detect the presence of Giardia Cysts on fresh vegetables
and irrigation water using PC
R technique to detect the status of Giardia cysts
in ten different agricultural areas of Damascus Countryside. 120 samples
including, 40 irrigation water and 80 vegetables samples were randomly
collected and tested. Out of 120 samples examined, only 25.8 % were
contaminated with Giardia cysts and these included 37.5% of irrigation water
samples and 20% of fresh vegetables samples. G. lamblia cysts were detected in
12.5% of examined samples, 17.5% of irrigation water samples and 10% of
fresh vegetables samples. The majority of contaminated samples (41.6%),
(25%) for Giardia and G. lamblia, respectively were from Misraba area without
statistically significant with Kafrein area, which showed the lowest
contamination with Giardia cysts (8.33%) and was free of G. lamblia cysts. This
study confirmed the importance of application of molecular biology methods in
the detection of Giardia on vegetables and their Irrigation water, since used
primers showed high specificity and sensitivity in the detection of the Giardia
genus and discriminate the Human pathogenic type, G. lamblia.
The study was conducted in four sites belonging to the Sheikh Badr district in Tartous
province. Ten different types were identified according to international standards. During
the 2016 and 2017 growth seasons, readings were recorded for phenotypi
c parameters as
well as physical and chemical analysis of fruit clusters. The studied types differed in many
characteristics. The results of the cluster analysis showed the distribution of the studied
types in two groups with a variance of 93%. The mean weight of the cluster varied
between the medium (349 g) and the large (1140.45 g). The ratio of total dissolved solids
(TSS) between the low (12.75%) and high (18.82%). the acidity between the very low
(3.53 g/l) and medium (6.38 g/l).
The Mediterranean region is world’s leading olive growing area. A large amount of
liquid waste results from olive oil extraction these wastewaters have a different effects an
environmental . In this study, four fungal isolates from Samples of soil
Polluted by olive
mill wastewater ,this isolates follow to several types from deuteromycetes, they are follow
to this types : Humicola sp., paecilomyces javanicus, Aspergillus terreus, Aspergillus
flavus. They isolated them on tow media (PDA, CzA) and identify them on colony
character ,Biometric and compare them with reference studies.
