title: Ozone Damage: Protection for Plants.
abstract: Tobacco plant leaves treated with dried particulate charcoal, diatomaceous earth, and powdered ferric oxide so that a covering formed on the leaves were relatively undamaged by comparison with untreated controls when exposed to as much as 0.9 part of ozone per million in the atmosphere. A theory is offered to explain the results.
