Tear gas in Plaza de la Dignidad, Chile
On December 20, 2019, Chilean security forces used unprecedented amounts of tear gas within a relatively small area against people participating in a peaceful and unarmed demonstration. Using open source analysis and fluid dynamic simulations, we measured the concentration of tear gas in the air in that territory to estimate the scale of health risks inflicted on civilians that day.
