Studies to Control Resuspension of Dust from Playgrounds

Dust resuspension from playgrounds can be a major contributor to urban air pollution. To address this issue, mitigation strategies such as the use of windscreens, water sprinkling, and dust suppressants have been reported in literature (Dong et al., 2007; Jeon et al., 2021; Taylor et al., 2015). However, the effectiveness of these measures is dependent on the soil type, wind patterns affected by green cover and surrounding. This study aims to provide insights into the effectiveness of different dust control strategies and offer potential solutions for widespread application in urban playgrounds. Laboratory-scale experiments were conducted to evaluate the influence of particle size distribution, wind speed and moisture content on dust resuspension from three different soil types. Numerical simulations will be performed to simulate the wind patterns that influence dust resuspension for a selected playground in Mumbai.
