Title: “Air pollution: From sampling to analysis”
Abstract
This “Air pollution: From Sampling to Analysis” lecture will reveal the process of taking air samples to then analyze them in a laboratory to
determine the levels of pollutants present in the air, thereby assessing air quality. It also deals with air monitoring techniques to provide real-time
readings of contaminants in the air. Air monitoring and air sampling are two different methods of looking at air quality. The air monitoring uses
electronic devices to provide real-time readings of contaminants in the air. The air sampling involves trapping air over a period of time in a
container that is then sent to a laboratory for analysis to identify and quantify specific compounds. Different techniques are used to collect air
samples depending on the pollutant being measured, including filters for particulate matter, absorbent tubes for gases, and specialized samplers for specific compounds. Air sampling devices draw a known volume of air through the collection media. The collected samples are then transported to the analytical/toxicological laboratory to analyze using various techniques like chromatography, spectroscopy, or gravimetric analysis to identify and quantify the pollutants. So, this lecture will be useful to gain the knowledge of air monitoring, air sampling, chemical and/or toxicological analyses.
