Lead dust storms

I chose this screen shot from the documentary film "The Lead Zone" because it poignantly captures the inevitability of leaded dust inhalation at the Port of El Callao.

• In this image, we see an elderly man forced to stop his bicylce in the middle of a large boulevard at the Port of El Callao, Peru as a truck backs into a mineral storage yard to his right. With the friction of tires, the dust below the truck rises to encase the man in a cloud of particulate as he patiently waits.
• Just before, Camila, a resident of a nearby barrio, explained to the camera how the dust-- leaded by leaks from mineral storage, transport, and robbery--enters into suspension due to the passing trucks. She calls them polvaderas– dust storms. Residents who must use this road can't help but incorporate these suspended particulates in their bodies: they have to breathe. 
• As if to demonstrate Camila's narrative, the scene of the man on the bicylce occurred. The tires lade the air with dust. The dust hangs over him. He waits, he must breathe.
