Details
This study develops plant essential oil emulsions to reduce PM2.5 using anionic properties and water solubility. Testing shows that a 0.025% kaffir lime essential oil emulsion is the most effective solution for reducing PM2.5 in both controlled and field environments.
The extreme weather caused by PM 2.5 is a global problem that directly attacks human health. This study aimed to develop medicinal plant essential oil emulsions to decrease PM 2.5 based on the chemical characterization of water-soluble anions and cations.
- Laboratory Findings: Spraying with a 0.025% kaffir lime essential oil emulsion effectively reduced PM 2.5 levels, showing a 3-6 fold decline compared to the control group after 2 hours.
- Field Experiments: Conducted at three Bangkok parks, the emulsion demonstrated superior performance over water. In calm wind conditions (10-20 km/hr), it reduced PM 2.5 levels from 37.0-44.0 µg/m3 to 13.5-16.5 µg/m3 within 3 hours.
Objective
To identify effective plant essential oil emulsions for PM2.5 reduction and to develop a product suitable for spray systems.
- To study the types of plant essential oil emulsions that are effective in reducing PM2.5 pollution.
- To produce plant essential oil emulsion products for use in spray systems to reduce PM2.5 pollution.
