As part of the HumanIC project, Dr. Waseem Hiwar delivered a comprehensive presentation on microbiological techniques for air and surface sampling in research and healthcare environments. The talk focused on methods to monitor environmental contamination through both random and systematic sampling strategies, with an emphasis on the importance of well-defined objectives and methodologies.
The presentation covered the use of various air sampling techniques—including gravitation, impaction, filtration, impingers, and centrifugal methods—and highlighted their advantages, limitations, and practical considerations. Key insights were shared on bioaerosol sampling, including the challenges of capturing viable microorganisms and selecting appropriate equipment for different conditions.
In terms of surface sampling, Dr. Hiwar reviewed multiple tools such as contact plates, dipslides, swabs, tapes, and vacuum systems. He also discussed a custom-developed automated multiplate passive air sampler (AMPAS) for time series analysis. The session concluded with case study data showing correlations between airborne microbial loads and indoor air quality metrics.
