Scent traps are devices designed to capture and analyze odors in the environment. They work by using various materials or chemicals that attract specific scents, allowing researchers to study the composition of those odors. This technology is often used in fields like environmental science and forensics to monitor air quality or identify substances at crime scenes. These traps can be simple, like sticky pads infused with attractants, or more complex systems that use pumps and filters. By collecting and preserving scents, scent traps help scientists and professionals understand the presence of certain chemicals or biological markers in a given area.
