Within the series of scientific meetings organized by the College of Applied Sciences and supervised by Dr. Hatem bin Muhammad Al-Tass, Assigned Dean of the College, the Fifth Scientific Meeting of the Chemistry Department was held for the second semester on Wednesday, 4^th Rajab 1439H,

Under the title:

Development of Chromatographic Methods to Study Heterocyclic Biochemistry in Volatiles   

Presented by: Dr. Ahmad bin Muhammad Hamid 

Assistant Professor at the Department of Chemistry 

The event witnessed the attendance of a number of male staff members at the Department of Chemistry in Al-Abediyah, female staff members in Al-Zaher and Al-Aziziyah, as well as the interested in the meeting. 

At the beginning of the meeting, Dr. Ahmad Hamid demonstrated an introduction about the hazards of chemical volatiles and the impact thereof on the environment and human health. He explained that the most prominent incident that prompted scientists to be interested in environmental pollution with biochemical volatiles was SMOG in 1952. The incident included fog filled with toxic and hazardous chemicals that left 12,000 human deaths in London within just one month. After studying such incident, scientists discovered that the main cause of many people’s death was sulfur dioxide SO2, a toxic and dangerous compound that was intensely existent in London due to the industrial revolution at that time.

In the same context, Dr. Hamid presented the researches and studies he conducted to develop different analytical methods to study the organic compounds in the atmosphere. He also developed analytical methods to follow up and calculate the speed of such reactions. In other words, he conducted laboratory experiments that suited the same conditions in the atmosphere.

After the scientific meeting, there was a discussion between the audience and Dr. Hamid on this subject. Moreover, he was handed a memorial shield for his participation in presenting such event.
