菠菜、甜菜、苦苣、燕麦和苜蓿植物被用于测定洛杉矶大都市空气中的农作物损害污染物。烯烃与NO/sub 2/在阳光影响下的催化氧化产生的氧化产物与臭氧产生的氧化产物非常相似。在烯烃氧化产物熏蒸植物时，常观察到催泪作用。这些调查表明植物在分析空气污染物中的效用。他们还首次表明，碳氢化合物，通常是无害的有机空气污染物，可以通过与空气中已知的物质反应造成严重损害。这样，这些实验有助于更好地了解烟雾问题。
Spinach, beet, endive, oat, and alfalfa plants were used for the determination of crop damaging pollutants in the air of metropolitan Los Angeles. The catalytic oxidation of the olefins with NO/sub 2/ under the influence of sunlight produces oxidation products very similar to those produced by ozone. In the plant fumigations with oxidation products of olefins, lachrymatory effects were often observed. These investigations demonstrate the utility of plants in analyzing air pollutants. They further show for the first time that hydrocarbons, normally harmless air pollutants of organic nature, can cause severe damage through their reaction with substances know to be in the air. In this way these experiments have contributed to a better understanding of the smog problem.
