تم تطوير وتوثيق مصدوقية طريقة تحليلية باستخدام جهاز الاستشراب السائل عالي الأداء HPLC تتمتع بالبساطة والانتقائية والدقة وذلك من أجل تعيين حمض س-فينيل ميركابتوريك. حُقّق الفصل الاستشرابي بواسطة استخدام عمود فصل من نوع (ODS-3 Inertsil) بأبعاد (5μ, 150 mm x 4.6 mm). وكانت درجة حرارة العمود 45 درجة مئوية. واستُخدم طور متحرك مؤلف من أسيتونتريل: ميتانول: ماء منزوع الشوارد محمض بحمض فوق الكلور (4/1/5 حجم/ حجم/حجمpH=3 ,) بمعدل جريان 1.5 مل/دقيقة واستخدام طول موجة مكشاف 225 نانومتر. أُجريت اختبارات ملاءمة النظام لتقييم مدى ملاءمة وفعالية النظام الاستشرابي بأكمله. حُسب زمن احتباس مادتي حمض س-فينيل ميركابتوريك وحمض البنزوئيك فقد وجدتا 17.3 و 15.6دقيقة، على التوالي، وأُجري التحقق من مصدوقية الطريقة المطورة من حيث الخطية والدقة والمضبوطية والنوعية وحد الكشف وحد التقدير الكمي. حيث كان حد الكشف: 126.0 مكغ/مل وحد التقدير الكمي: 0.38 مكغ/مل لمادة س-فينيل ميركابتوريك، وبمردود97.183% :. أظهرت المادة استجابة خطية ضمن المجال 0.5-20 مكغ/مل. تهدف هذه الدراسة إلى تطوير طريقة تحليلية باستخدام جهاز الاستشراب عالي الأداء والتحقق من مصدوقيتها، ويمكن استخدام الطريقة المقترحة لتقدير مستقلب البنزن هذا في البول كونها بسيطة ودقيقة وانتقائية.

Soil pollution with heavy metals has become a serious global threat, largely due to anthropogenic activities, and cadmium (Cd) is one of the most toxic known heavy metals. This study aimed to assess cadmium levels in several agricultural soils in several Syrian regions. Soil samples were taken from six agricultural lands, prepared, and processed to determine the total content of cadmium using a graphite furnace atomic absorption spectrometry. The results showed that the values of cadmium concentration ranged between 0.60 and 1.48 ppm in the studied soil samples, exceeding the permissible limit in some areas. Cadmium values were higher in farmland soils near industrial facilities than those far from them. This study indicates the spread of Cd contamination throughout the study area, significantly near the industrial activities; thus, it may impact local agricultural production safety and human health.

On a daily basis, individuals are exposed to potential poisoning by different sources such as medicines, food, alcohol, pesticides, and chemical cleaning materials. In these circumstances, individuals often need to undergo medical emergency interventions to manage the serious consequences that can appear simultaneously with the poisoning or in the long term. Indeed, the nature and circumstances of daily poisoning cases vary among socio-demographic backgrounds. This fact requires the development of a medical emergency system that integrates emergency toxicity treatments. This perspective further suggests the development of appropriate prevention and treatment programs according to the geographical distribution of the recorded daily poisoning incidences. A database was built in regards to the many acute poisoning cases recorded in a number of emergency facilities based on four geographical zones in Syria. The data included the source of the poisoning and the individual’s identity demographics, like age, gender, profession, the area of residence, and employment. The statistical analysis proved that there is an evident relationship between the types of daily poisonings and the demographics of the individuals poisoned including the geographical location. Thus, this study showed the importance of developing a probabilistic mapping on a national scale of the possible daily poisoning incidents based on the individuals’ demographics. Furthermore, this approach allows local and national authorities to develop anti-poisoning centers and provide the equipment and most appropriate medical materials according to the needs of each region.
