Opis:: Studies on the currently used organophosphorus insecticides with respect to their environmental levels and effective remediation technologies for their residues in water have been considered as a source of major concern. This study was carried out to monitor the presence of organophosphorus in drinking water plants (Kafr-El-Shiekh, Ebshan, Elhamoul, Mehalt Aboali, Fowa, Balteem and Metobess) in Kafr-El-Shiekh Governorate, Egypt. Furthermore, it was carried out to evaluate the efficiency of different remediation technologies (advanced oxidation processes and bioremediation) for removing chlorpyrifos in drinking water. The results showed the presence of several organophosphorus pesticides in water sampling sites. Chlorpyrifos was detected with high frequency relative to other compounds in drinking water. Nano photo-Fenton like reagent (Fe2O3(nano)/H2O2/UV) was the most effective treatment for chlorpyrifos removal in drinking water followed by ZnO(nano)/H2O2/UV, Fe3+/H2O2/UV and ZnO/H2O2/ UV, respectively. Bioremediation of chlorpyrifos by effective microorganisms (EMs) removed 100% of the chlorpyrifos initial concentration after 23 days of treatment. There is no remaining toxicity in chlorpyrifos contaminated-water after remediation on treated rats with respect to cholinesterase activity and histological changes in kidney and liver relative to control. Advanced oxidation processes especially with nanomaterials and bioremediation with effective microorganisms can be regarded as safe and effective remediation technologies for chlorpyrifos in drinking water.

Opis:: The study was carried out to evaluate the efficiencies of various remediation technologies (advanced oxidation processes and bioremediation) for removing diazinon and malathion residues from water. Nano photo-Fenton reagent (Fe0(nano)/H2O2AJV) was the most effective treatment for diazinon and malathion removal while ultraviolet alone was the least effective one. Bioremediation of diazinon and malathion by effective microorganisms (EMs) removed about 100% of their initial concentration. There was no remaining toxicity in contaminated water after remediation except for ultraviolet alone on treated rats. Advanced oxidation processes with nanomaterials and bioremediation with effective microorganisms can be regarded as safe and effective remediation technologies.

Tytuł:: Echinochloa colonum resistance to bispyribac-soduim in Egypt - occurrence and identification

Opis:: Identification and mechanism of Echinochloa colonum (L.) resistance to bispyribac-soduim via physiological and anatomical differences between susceptible and resistant biotypes was investigated. The physiological and anatomical differences that were take into account were growth reduction, chlorophyll content reduction, protein analysis, lamina thickness and xylem vessel diameter in both susceptible and resistant biotypes of E. colonum. The results showed the growth reduction fifty (GR50) of resistant biotype was 10.2 times higher than that of the susceptible biotype E. colonum treated with bispyribac-soduim. The chlorophyll content was highly reduced in the susceptible biotype relative to the resistant one of E. colonum treated with bispyribac-soduim. An anatomical test showed significant differences in the cytology of susceptible and resistant biotypes of E. colonum treated with bispyribac-soduim with respect to lamina thickness and xylem vessel diameter. Furthermore, leaf protein analysis showed significant differences between the susceptible and resistant biotypes of E. colonum in the number and the density of protein bands. The resistance of E. colonum to bispyribac-soduim may be due to the faster metabolism of bispyribac-soduim below the physiologically active concentration or the insensitivity of its target enzyme, (acetolactate synthase). These results implied the occurrence of E. colonum resistance to bispyribac-soduim in Egypt and provide conclusive evidence that a single resistance mechanism alone cannot explain insensitivity in E. colonum to bispyribac-soduim.

Opis:: In this study, foliar sprays of Fenton solutions (Fenton reaction, Fenton-like reaction and Fenton complex), titanium dioxide (TiO2) and the recommended fungicide (chlorothalonil) were estimated in the control of sugar beet leaf spot caused by Cercospora beticola under field conditions in two growing seasons. In addition, the impacts of these treatments on some crop characters (leaf dry weight, root fresh weight, soluble solid content, sucrose content and purity of sugar) were examined. Biochemical and histological changes in the livers and kidneys of treated rats compared to an untreated control were utilized to assess the toxicity of the examined curative agents. Overall, chlorothalonil and Fenton complex were the most effective treatments for disease suppression in both tested seasons followed by Fenton-like reagent, Fenton’s reagent and TiO2, respectively. Growth and yield characters of treated sugar beet significantly increased in comparison to an untreated control. There were mild or no (biochemical and histological) changes in the livers and kidneys of treated rats compared to the control. Fenton solutions and TiO2 may offer a new alternative for leaf spot control in sugar beet.

Opis:: This study was done to assess the antifungal effect of some biocontrol agents effective microorganisms (EMs1), Pseudomonas fluorescences, and Bacillus pumilus, titanium dioxide (TiO2) nanoparticles, black cumin and wheat germ oils as well as the recommended fungicide (flutolanil) against root rot of tomato. Moreover, gas chromatography-mass spectrometry (GC-MS) examination was completed to identify the bioactive compounds in plant oils (dark cumin and wheat germ). Also the impact of these medicines on some biochemical and growth parameters of tomato was examined. Flutolanil was the best treatment followed by dark cumin, TiO2, EMs1, Pseudomonas fluorescens, Bacillus pumilus and wheat germ oil, individually in both test seasons. The outcomes demonstrated a marked increase in each biochemical character (chlorophyll substance, peroxidase and polyphenoloxidase) and plant development (height and fresh and dry weight) under all the tried treatments in comparison to the controls.

Opis:: This study was carried out to monitor the presence of organochlorine in drainage water in Kafr-El-Sheikh Governorate, Egypt. Furthermore, to evaluate the efficiencies of different remediation techniques (advanced oxidation processes [AOPs] and bioremediation) for removing the most frequently detected compound (lindane) in drainage water. The results showed the presence of several organochlorine pesticides in all sampling sites. Lindane was detected with high frequency relative to other detected organochlorine in drainage water. Nano photo-Fenton like reagent was the most effective treatment for lindane removal in drainage water. Bioremediation of lindane by effective microorganisms (EMs) removed 100% of the lindane initial concentration. There is no remaining toxicity in lindane contaminated-water after remediation on treated rats relative to control with respect to histopathological changes in liver and kidney. Advanced oxidation processes especially with nanomaterials and bioremediation using effective microorganisms can be regarded as safe and effective remediation technologies of lindane in water.
