Zahidah Marzuki-Liquefied Petroleum Gas (LPG) in insecticide aerosol
Insecticide aerosol is commonly used in Malaysia. Every household in Malaysia uses insecticide aerosol almost everyday especially in some rural areas. It is known that liquefied petroleum gas is one of the chemicals present in an aerosol as to replace the use of CFC. However, LPG is slightly harm to our health and environment. But, the frequent use of insecticide aerosol might be harmful to health if no precautions taken. Some serious cases, inhalation of too much LPG will cause asphyxiate, which not everyone are aware of. Therefore, my analytical problem is to determine the amount of LPG in insecticide aerosol so as to control the amount of the insecticide that can be used and accordingly. The matrix would be the solvent that is used to dissolve LPG in the insecticide aerosol, where kerosene is one of it.

Similar Analytical Problem:
Lauren Saurer - Vapor Intrusion in Building
Analytes: trichloroethylene and tetrachloroethylene
Relevance: health and environment
Similarity: our studies focus on the quality of indoor air and focuses on to quantitatively determine the presence of analyte of interest in the indoor air of affected surrounding.
Difference: her analytes of interest are single compounds whereas my analyte might have different composition from different sample depending on the manufacturer. So, in my study, I need to identify the characteristic of my analyte in the samples first before I'm able to quantitatively determine the analyte.
My preferred technique is gas chromatography with split flame ionization/ electron capture detection. Other analytical problems that use same techniques "Silicones in Cosmatics" by Melissa which uses GC/MS, "Vapor Intrusions in Building" by Lauren which uses GC/FTMS, and "Butanol Production from Clostridia Fermentation" by David which uses GC with FID detector.
