Not the best picture, I know. If you look closely, you will see a white truck with a sort of "sprayer" on the back, blowing out a smokey substance that hangs in the air for some time after it passes. This is the public health department's "Contra Dengue" movement. Several times a year, they send people to your house to walk through, put insecticide of some kind in your drains, and check all the places in your house where you might have standing water where mosquitos could lay eggs. Apparently they also send a truck around to blow mosquito killing fumes into the trees in residential areas. What the truck is spraying, I have no idea. Years of working for MSU Entomology made me terribley paranoid of things being sprayed out of the back of trucks to kill insects. Yet there were people walking around on the street as this truck went by, and they seemed unfazed.
The smoke hangs in the air a bit and I imagine settles on the leaves and the ground, doing it's job. How much of it is in my lungs?
