Abstract：
Background: The application of phytoremediation by utilizing plants has been used to control oil pollution in waters. One of the plants that can act as a phytoremediator is the hyacinth because this plant can reduce various pollutants including petroleum hydrocarbons. This study aims to study the reduction ability of petroleum hydrocarbons at different concentrations including improving water quality. Methods: This study consisted of one treatment (petroleum hydrocarbon) consisting of five factors with three replicates. The treatments consisted of 10 ppm (E1), 30 ppm (E2), 50 ppm (E3), 70 ppm (E4), 90 ppm (E5), and (E0) without aquatic plants as controls. The treatments were observed daily and measured from the first day (D-1), the seventh day (D-7), and the 14 th day (D-14). The water quality in each treatment was also measured, such as water temperature, pH, and dissolved oxygen. Results: The results showed that the hyacinth plant was able to reduce hydrocarbon in terms of total petroleum hydrocarbon (TPH) by 79% while it was only between 17-27% naturally without the hyacinth. The reduction of TPH in the water was in line with the decrease of chlorophyll in the leaves of hyacinths, and it was followed by the increase of dissolved oxygen in the water media. Conclusions: In conclusion, hyacinths can reduce petroleum hydrocarbons and they can improve the water quality as well.
摘要：
背景：通过利用植物进行植物修复的应用已用于控制水域中的石油污染。风信子是可以作为植物修复剂的植物之一，因为这种植物可以减少包括石油碳氢化合物在内的各种污染物。本研究旨在研究不同浓度下石油烃的还原能力，包括改善水质。方法：本研究由一种处理（石油烃）组成，由五个因素组成，重复三个。处理包括10ppm（E1），30ppm(E2),50ppm（E3），70ppm（E4），90ppm（E5），和（E0），没有水生植物作为对照。每天观察治疗，并从第一天开始测量（D-1），第七天（D-7）第14天（D-14）。还测量了每种处理的水质，如水温，pH值,和溶解氧。结果：结果表明，风信子植物能够将总石油烃（TPH）中的碳氢化合物减少79％，而没有风信子的自然含量仅为17-27％。水中TPH的减少与风信子叶片中叶绿素的减少是一致的，其次是水介质中溶解氧的增加。结论：总之，风信子可以减少石油碳氢化合物，它们也可以改善水质。
