Figure 3

Soils (from the Atacama Yungay site and the Mojave +CIMA site) were extensively washed and exposed to light (400–700 nm), against ±100 mM DMSO (·OH scavenger) and an H2O2 control, using commercial TiO2 (inset) as additional control, given its presence in the tested desert soils. The other tested desert/control sites gave similar data (not shown). Error bars designate s.d.
