Monitoring and Measurement Techniques for Bioaerosols

The secrets to successful indoor air quality (IAQ) management to mitigate the health risks posed by bioaerosols are monitoring and measurement. Sampling such as impactors, filtration, and impingers are various techniques of sampling that could be used to collect bioaerosol samples to be analyzed further. The identification and quantification of biological particles can be done using different methods of analysis, which include culture-based and molecular methods, and sensors enable continuous monitoring of bioaerosol concentrations in real time or at a minimum instantaneously. Although these methods have evolved far, issues have been lingering around the aspect of determining precise and consistent measurements, especially in fluctuating environmental conditions with respect to temperature, humidity, and flow. The problems with measurement are based on various elements, such as some microorganisms that are not able to grow in culture, the sensitivity of the sensors, and issues with the distinction of viable and non-viable particles. The sampling and detection processes are being enhanced, improving the precision of the sensors, and the utilization of mediating technologies such as AI in the analysis of the data. We should all do this to have enhanced knowledge on bioaerosols, improve IAQ, and safeguard human health both at home in offices and in hospitals. With the availability of a developed technology, better, efficient, and comprehensive bioaerosol monitoring systems will assist in the achievement of a healthy indoor environment.
