Commercial processing procedures led to a gradual decrease in the total amount of 14C-residues in oils. The complete refined oil from treated seeds lost about 80% of the total 14C-residues. The major part of 14C-residues after feeding rats with the extracted soybean seeds for 72 hr was eliminated via expired air (45%) while radioactivity in urine and feces accounted for 18% and 12% of the taken 14C- residues, respectively. The results revealed that profenofos residues induced abnormal hepatic and renal function which was remarkably attenuated with co-administration of water extract of cinnamon powder thereby suppressed the deviation in the liver and kidney function markers. From the present investigation it can be concluded that the used plant extract exerted prophylactic beneficial action against profenofos induced hepatic and renal damage via its antioxdating potential effects.}, keywords = {14C-Profenofos residues,Commercial processing,bioavailability,toxicity,Cinnamon and Protective effect}, url = {https://ejchem.journals.ekb.eg/article_1386.html}, eprint = {https://ejchem.journals.ekb.eg/article_1386_1ca8be878e0c96e5f0f60c36eaa10cfb.pdf} } @article { author = {}, title = {Foliar Application of Calcium Chloride to Decrease Ethion Residues in the Oil of Chamomile Flowers and Soybean Seeds}, journal = {Egyptian Journal of Chemistry}, volume = {54}, number = {2}, pages = {175-187}, year = {2011}, publisher = {National Information and Documentation Centre (NIDOC), Academy of Scientific Research and Technology, ASRT}, issn = {0449-2285}, eissn = {2357-0245}, doi = {10.21608/ejchem.2011.1387}, abstract = { THE EFFECTIVENESS of the foliar application of different …… concentrations of calcium chloride solution (0.5, 1 and 1.5%) to reduce ethion residues in chamomile flowers and soybean seeds was studied.

The concentration of 14C-ethion activity was decreased by increasing the concentration of CaCl2 solution. The percentage of removal due to calcium chloride application increased from 33% to 36% and from 9% to 23% for both chamomile flowers and soybean seeds after 30 days of the last application. The concentration of 14C- ethion on chamomile and soybean oils at 30 days after the last application was 0.36 and 0.43 ppm, respectively at 1.5% CaCl2. Chromatographic analysis of oil extracts of both plants revealed the presence of ethion monooxon, ethion dioxon, O,O-diethyl phosphorothioate, O-ethyl phosphorothioate, in addition to the parent compound.

The coating performance of the resins was evaluated using international standard test methods (ASTM) and involved the measurement of phyisco- mechanical properties such as viscosity, drying time, specular gloss, pencil hardness, adhesion, flexibility and impact resistance. Chemical resistance of the resins to water, acid, alkali and solvent was also evaluated to ascertain their suitability as a surface coatings vehicle.
