AI Technical Summary

Technical Problem

Existing technologies are insufficient to comprehensively and accurately study the effects of air pollution on the volatile odor components of plants, especially the changes under different pollutant concentrations, distances, and time conditions.

Method used

A system device was designed, including an air supply device, a pollutant supply device, a sampler, and a gas collection unit. By setting up multiple samplers at different distances to collect gas samples, and using a GC-MS instrument to detect the components, the impact of air pollution on the volatile odor components of plants was investigated.

Benefits of technology

It enables precise detection of volatile odor components of plants under different distances, concentrations, and time conditions, and can determine the individual or synergistic effects of pollutants on plant volatile components. It can also be connected to a pollinating insect behavior experimental device to clarify the impact of multi-scale air pollution on insect behavior.
