多環芳香性碳氫化合物(polycyclic aromatic hydrocarbons, PAHs)為有毒的環境有機污染物，部分PAHs有很強的致癌性和致突變性，且結構穩定容易長時間停留在環境中造成累積的情況。針對去除環境中PAHs的研究已經有廣泛的討論，其中利用植生整治（Phytoremediation）去除土壤、污水、底泥中的汙染物也有不少研究，該方法為了解植物吸收的特性來去除常見的有機污染物。本篇選用臺灣常見的觀葉植物黃金葛，針對其根部吸收PAHs的累積特性以及轉移機制研究，進而了解黃金葛對於特定PAHs有達到植生整治的效果，藉由植物根系作用，吸收污染物質，並運送至地面以上植株部位，以鏟除植被方式達到除污之目的。
研究結果顯示Naphthalene在黃金葛植物根部中的濃度呈現不規則變化，而Fluorene有較弱的吸收累積，對於Phenanthrene 、Fluoranthene、Pyrene、和Benzo(g,h,i)perylene這四種PAHs有強烈的吸收累積。Phenanthrene 、Fluoranthene、Pyrene和Benzo(g,h,i)perylene這四種PAHs，皆有由根部轉移到莖部的現象，接著轉移到葉子的情況很不明顯，顯示PAHs在植物體中的轉移是受到限制的，綜合以上我們可以利用黃金葛根部強烈吸收以及轉移PAHs的特性來去除環境中的Phenanthrene 、Fluoranthene、Pyrene和Benzo(g,h,i)perylene這四種PAHs。
利用根部吸附模型的理論計算和實驗數據做比對，發現到添加最高濃度的PAHs水溶液(solution at the beginning 500μg/L)實驗值遠高於理論值且偏離線性範圍，推測高濃度的PAHs水溶液有毒害黃金葛的現象造成植物根部的PAHs濃度偏高，也許黃金葛根部對於Phenanthrene 、Fluoranthene、Pyrene和Benzo(g,h,i)perylene這四種PAHs的各別最大負荷濃度不能超過7505±575，13551±909，13680±1025，12612±1042 μg /kg dry wt。
