Conference Countdown Challenge

Indoor Air 2024 will be hosting a puzzle challenge to highlight recent research/findings related to indoor environmental quality. 

Here’s how it works:

  • Submit images of overview figures, microscopy, graphs, photographs, or anything else that highlights your work.
  • Images will be evaluated on a rolling basis and selected for inclusion.  All images submitted prior to image selection will be considered (after you submit an image it will be considered for all subsequent weekly and bi-weekly selections), so you only need to submit an image once.

Challenge Rules:

Leaderboard and Prizes
  • The image must be an original work by you
  • You must own the copyright or have written permission of the copyright owner
  • You give us permission to post the image on the Indoor Air 2024 website and use it (with attribution to you) in other materials to promote the conference
  • Images must be appropriate and comply with the ISIAQ code of ethics https://www.isiaq.org/isiaq_code_of_ethics.php
Player Rules
  • Post your name and organization to the leaderboard, which will be publicly visible along with your time if you score a top time.  You can play an unlimited number of times each week.
  • The one winner with the fastest time each week will be eligible to receive the prize.  In the event of a tie, the person who posted the winning time first will receive the prize for that week.
  • You can only win one prize throughout the entire competition, but you are welcome to continue to play the puzzle to have your name posted on the leaderboard.
  • You must attend the conference in-person to collect the prize because we are unable to ship them to everyone.  You must be registered at least 1 week prior to the conference (when we will create the list of winners) and also attend in-person.
  • If the first winner for a particular week is unable to collect the prize, the prize for that week will then be made available to the next fastest time and so on until a winner is selected for that week.

Outstanding puzzle submissions will be honored at the Indoor Air 2024 Convention!

Prizes:

Leaderboard Prize

The leading puzzle solvers for each week will receive an action waterproof camera at the conference!

Submission Prize
The top 8 submissions will receive an honorary award and recognition during the conference.

Puzzle 7: Jingle Bells, What are Those Smells?

Principal Investigator: Dr. Dustin Poppendieck

Contributors: Rileigh Robertson, Michael Link

Description of Findings: 

    •  Every year in the United States conifers are purchased to act as Christmas trees in homes where they emit volatile organic compounds (VOCs) to the indoor environment. Although many studies have measured the ecosystem-level emissions of VOCs from conifers outdoors, little is known about VOC emission rates once a conifer is brought indoors. This research quantified monoterpene emissions from a live tree along with secondary formaldehyde formation from ozone exposure. We conclude that the placing of a live Christmas trees indoors is a source of VOCs comparable to sources such as air fresheners, building materials, and personal care products.

Description of Findings: 

    • Pictured are a variety of particles found in household fallout via Nile red, a selective fluorescent dye, and confocal microscopy (405-555nm). This method is being explored to identify and characterize microplastics in household indoor air based on the fluorescent spectral profile of known materials. Through this work, we hope to identify a single combined fluorescence index value that reflects the unique fluorescence patterns of each material to aid in characterizing microplastics.

Puzzle 3: Monitoring and Measuring Viral Transmission

Principal Investigator: Andrea R. Ferro

Student: Mahender Singh Rawat

Contributors: Alan D. Roberts and Deborah M. Brown

Description of Findings: 

    • This research examines the dispersion of a laboratory strain of influenza A virus, H3N2, caused by human walking. The virus was produced in a sealed biosafety level 2 lab with no ventilation using a nebulizer. To monitor the aerosols, various devices were used, including the TSI APS and several PurpleAir Model PA-II low-cost particle monitors. The TSI APS utilized time-of-flight technology to measure and categorize particles with aerodynamic diameters ranging from 0.5 to 20 microns while estimating particle concentration through light scattering between 0.37–20 μm. To collect viral aerosols, three Glass Midget Impingers filled with PBS were employed at specific locations within the room: behind the nebulizer and at varying distances in front of it, all positioned approximately at a height of 1.5m.
