Identificación de hidrocarburos aromáticos policíclicos (HAPs) en el pm2.5 del aire de Pamplona-Colombia

Abstract

Air pollution is considered a serious environmental problem due to the presence in the atmosphere of hazardous materials such as metals and polycyclic aromatic hydrocarbons (HAPs) content in the particulate matter (PM). The (PAHs) are priority pollutants from the air due to its extremely dangerous to human health. In order to identify the polycyclic aromatic hydrocarbons present in the organic matter from the air PM2.5 Pamplona, the respirable fraction PM2.5 particulate material was monitored using equipment Partisol 2025 Plus Palmflex quartz filters. The filters were subjected to ultrasonic extraction using dichloromethane three separate solvents, acetone and dichloromethane: acetone (3:1). To identify PAHs, the extracts were analyzed in a gas chromatograph with FID detector plus HP6890. For the first time in the air PM2.5 Pamplona-Norte de Santander, are detected and identified 12 PAHs, among which stands out the benzo [a] pyrene, which is considered one of the most potent carcinogens.
