Case Study: Bioaerosol Sampling in Public Transportation

The public transportation management department of a city decided to monitor the bioaerosols in the air inside subway carriages to ensure the health and safety of passengers while riding the subway. To achieve this goal, they utilized bioaerosol sampling equipment.

Setup of Sampling Equipment: The public transportation management department installed bioaerosol sampling equipment inside subway carriages, including samplers and sample collectors. These devices were positioned at different locations within the subway carriages to cover the entire space where passengers are situated.

Sampling Process: The sampling equipment automatically sampled the bioaerosols in the air during subway operation. The sampler drew in the air inside the carriage, capturing bioaerosol particles into the sample collector.

Recording Sampling Data: The sampling equipment recorded the collected bioaerosol sample data, marking the sampling time, location, and relevant parameters. This data could be used for subsequent analysis and comparison.

Analysis and Assessment: The public transportation management department sent the collected bioaerosol samples to laboratories for analysis and assessment. They evaluated the air quality and hygiene conditions inside subway carriages by detecting the presence and concentration of biological markers such as bacteria, viruses, and fungi.

Result Reporting: Based on the analysis results, the public transportation management department generated reports and took corresponding measures as needed, such as enhancing carriage cleaning and disinfection, improving the efficiency of ventilation systems, etc., to enhance the subway passengers' riding experience and health safety.

By using bioaerosol sampling equipment, the public transportation management department could timely monitor biological pollutants inside subway carriages, ensuring the health and safety of passengers.
