进行了一项植物研究，以检查通过使用粉末活性炭控制微量有机物的可行性。结果表明，PAC可将三卤甲烷的生成水平降低56%。包括总有机碳、荧光强度、阈值气味数、pH值、浊度、游离有效氯和UV的测量。包括12个参考文献、表格和图表。

A plant study was conducted to examine the feasibility of trace organic control through the use of powdered activated carbon. Results indicate that PAC can reduce trihalomethane formation levels up to 56 percent. Measurements of total organic carbon, fluorescence intensity, threshold odor number, pH, turbidity, free available chlorine, and UV are covered. Includes 12 references, tables, figures.
