Survey on the Moisture and Ash Contents in Agricultural Commodities in Al-Rass Governorate, Saudi Arabia in 2017
No full textResearchers and governments are paid great interest concerning food safety and quality of food stuff. Determination of moisture and ash contents was ac-complished by using simple, easy and low cost method to establish a database for agricultural commodities.Twenty four types of agricultural commodities were collected from the local market in Al-Rass governorate, Al-Qassim region, Saudi Arabia. The samples were collected in the period from the beginning of January 2017 to the end of July 2017. The survey show that higher values of moisture contents were found in tomato and cucumber (95.79 and 94.65%, respectively)while the higher values of ash content were found in leafy vegetables in particu-lar spinach and watercress of 1.91% and 1.51% respectivel
Determination of the Level of Organophosphorus Pesticides in Tomato Using GC-MS/MS and the Concentration of Some Heavy Metals Using FAAS
No full textThis study was carried out to develop and apply a quick, yet efficient, analytical method for simultaneous determination of the residues of the 86 pesticides repeatedly detected in food commodity in Al-Rass province of Al-Qassim Region, Saudi Arabia. The suggested method is based on QuEChERS extraction procedures based on acetonitrile followed by a dispersive solid-phase extraction (d-SPE) with primary-secondary amine (PSA) and bulk of carbograph for clean-up, was applied prior to GC-MS/MS analysis, focusing in particular on tomato crops. The second aim of the study was to measure the levels of some heavy metals using FAAS technique, particularly, Cu, Cd, Zn, Fe and Pb. The third aim was to evaluate the effectiveness of some common household-type preparations and handling procedures for tomato on reducing the levels of the detected pesticide residues as well as the heavy metals. The current findings could provide that the proper home preparation of tomato samples, in particular, soaking in 2% sodium chloride solution and soaking in commercial 5% acetic acid has led to effective elimination of the pesticide ethion from those samples. However, results have shown that there was no significant effect on the levels of heavy metals in the investigated tomato samples after applying the common types of household treatments

Advanced Dye Sorbents from Combined Stereolithography 3D Printing and Alkali Activation of Pharmaceutical Glass Waste
No full textAdditive manufacturing (AM) technologies enable the fabrication of objects with complex geometries in much simpler ways than conventional shaping methods. With the fabrication of recyclable filters for contaminated waters, the present work aims at exploiting such features as an opportunity to reuse glass from discarded pharmaceutical containers. Masked stereolithography-printed scaffolds were first heat-treated at relatively low temperatures (680 and 730 °C for 1 h) and then functionalized by alkali activation, with the formation of zeolite and sodium carbonate phases, which worked as additional adsorbing centers. As-sintered and activated scaffolds were characterized in terms of the efficiency of filtration and removal of methylene blue, used as a reference dye. The adsorption efficiency of activated printed glass was 81%. The 3D-printed adsorbent can be easily separated from the solution for reuse
