Six reforestation areas were sprayed with 2,4,5-T esters. Leaf samples from the areas were analyzed for the esters, tetrachlorodioxin, and dehalogenated phenoxyacetic acid esters. Tetrachlorodioxin was found in one leaf sample only, but the level found, relative to the amount of 2,4,5-T ester found, was lower than in the formulation material used in the study. The concentration of the dichlorophenoxyacetic acid esters present in several leaf samples was greater, relative to the 2,4,5-T ester, which indicated a photochemical breakdown of the 2,4,5-T in the environment.
六个重新造林区域喷洒了2,4,5-T酯。对这些区域的树叶样本进行了酯类、四氯二恶英和脱卤苯氧基乙酸酯的分析。仅在一个树叶样本中发现了四氯二恶英，但相对于所发现的2,4,5-T酯的量而言，所发现的该物质水平低于研究中使用的配方材料中的水平。相对于2,4,5-T酯，几个树叶样本中存在的二氯苯氧基乙酸酯浓度更高，这表明环境中2,4,5-T发生了光化学分解。
