Deadly Plumes
Photograph by Peter Essick
A rustic brick kiln in San Luis Potosí, Mexico, belches black smoke at brickmakers, who sustain invisible damage with each day of work. The smoke is rich in PAHs from incompletely burned wood and oil used to heat the furnace. Scientists have documented DNA damage in some children at the site, likely caused by toxic exposure.
