ملخص البحث المنشور:
- A simple HPLC-UV method was used for monitoring the elution profile of methyl methacrylate and methacrylic acid monomers from poly (methyl methacrylate) resin. The study was conducted on two cold-curing and two heat-curing discs in both distilled water and artificial saliva. The results showed that the leached amounts from cold-curing resin in both media were higher than that from heat-curing resin. The leached amount into the artificial saliva from both resins was much higher, compared to that into water. The present results indicated that the risk of possible trauma to oral soft tissues could be minimized by immersing the oral appliances in water for one week before insertion.
- This study was carried out to find chlorinated pesticides residues in foodstuff of animal origin in Jordan through 2013 and 2014. Ministry of Environment of Jordan asked the Royal Scientific Society to monitor the pesticides residues of these persistent organic pollutants (POPs) in foodstuff of animal origin under the supervision of official scientific committee. Results of milk products showed that there were two samples from 30 were contaminated, but less than the maximum residue limit (MRL). Results of table eggs showed that 11 samples from 35 were contaminated, but less than MRL. Results of meat and poultry analysis showed that 21 samples from 55 were contaminated, but less than MRL. However, the contaminated samples were contained β-HCH, γ-HCH, p,p′-DDT, p,p′-DDE, p,p′-DDD, heptachlor and aldrin. Conclusions and recommendations were reported to minimize pesticides residues in foodstuff of animal origin in Jordan.
