Artificial smog resulted in a decrease in the permeability of the cells of Pinto bean leaves to radioactive phosphate when the plants were exposed to a mixture of 1 p.p.m. of ozone with an excess of 1-n-hexene for periods up to 3 hr. Longer exposures resulted in a reversal of this effect and increased the permeability of the leaf cells to phosphate. This increased permeability was associated with the appearance of visible smog damage on the leaves. Potato-tuber disks showed similar effects from smog on uptake of P/sup 32/ from a buffer solution and on both uptake and loss of water over short periods of time.
