“…Toksisitas logam seng dengan konsentrasi tinggi dalam waktu yang lama dapat mempengaruhi sintesis klorofil sehingga menghambat proses fotosintesis (Phukan, 2015). Keberadaan logam seng di perairan dapat membahayakan keberlangsungan lingkungan dan mempengaruhi semua komponen ekosistem lingkungan (Hassan, 2016). Efek logam seng dalam suatu sistem perairan ditentukan oleh beberapa faktor seperti kuantitas logam berat dan komposisi fraksi terlarut dan partikulat logam berat didalam perairan (Najamuddin, 2016).…”

Logam seng pada konsentrasi tertentu dapat terakumulasi di dalam air, biota dan sedimen pada perairan yang dapat menimbulkan efek toksik terhadap organisme sehingga untuk mengatasi permasalahan tersebut telah dikembangkan teknologi alternatif yang dikenal dengan fitoremediasi. Tujuan dari penelitian ini adalah memanfaatkan Hydrilla sp. sebagai agen fitoremediasi untuk menurunkan konsentrasi logam seng (Zn) pada limbah industri kertas. Tahap penelitian meliputi uji karakteristik awal air limbah dan Range Finding Test (RFT), penyiapan 75 g Hydrilla sp. dan aklimatisasi Hydrilla sp. selama 5 hari. Hydrilla sp. ditumbuhkan pada reaktor selama 18 hari dalam 5 liter limbah industri kertas dengan konsentrasi 100% dan 5 liter akuades sebagai kontrol (0%). Variabel pengamatan meliputi pengukuran nilai pH, suhu dan identifikasi perubahan warna daun Hydrilla sp. Limbah hasil fitoremediasi pada waktu pemaparan 3, 6, 9, 12, 15, dan 18 hari dilakukan analisis logam seng (Zn) dengan ICP-OES. Berdasarkan hasil analisis menunjukkan bahwa pada hari ke-0 sampai hari ke-12 persentase logam seng yang hilang sebesar 50% dan pada hari ke-18 mengalami penurunan persentase sebesar 25%. Kata kunci : Fitoremediasi, Hydrilla sp., limbah industri kertas, logam seng. Zinc metal at certain concentrations can accumulate in water, biota, sedimentary in waters which can cause toxic effects on organisms. So as to overcome these problems alternative technologies have been developed known as phytoremediation. The purpose of this research is to utilize Hydrilla sp. as a phytoremediation agent to reduce zinc metal concentrations in paper industry wastes. The research phase included preliminary research that is initial characteristic of wastewater and Range Finding Test (RFT), preparation of 75 g of Hydrilla sp. and Hydrilla sp. acclimatization for 5 days, then Hydrilla sp. grown on reactor for 18 days in 5 liters of paper industry waste with 100% concentration and 5 liters of akuadest as control (0%). Observation variables include measuring pH values, temperature and identify discoloration of Hydrilla sp. leaves, then the phytoremediation waste at exposure time of 3, 6, 9, 12, 15 and 18 days was analyzed zinc (Zn) with ICP-OES. Based on the analysis results show that on days 0 to day 12 the percent amount lost by 50% and on the 18th day the amount of zinc metal lost decreased by 25%. Keywords : Phytoremediation, Hydrilla sp., paper industry waste, zinc metals.

“…We initiated the study by selecting a suitable plant for extracting AAs from contaminated environments. Hydroponic and/or terrestrial plants, including Myriophyllum aquaticum (parrot feather watermilfoil), Elodea densa (egeria densa), Hydrilla (waterthyme), Pontederia crassipes (water hyacinth), Pistia (water lettuce), and Triticum aestivum (wheatgrass), that are commonly used for phytoremediation of contaminated areas were tested in this study. ,,− We then investigated the effect of pH on AA absorption by selected plant species because soil pH was previously identified as a major geochemical factor in BEN endemic areas. , Furthermore, the possibility of phytodegradation of AAs by plant metabolism was also explored. It is anticipated that the developed phytoremediation method will find wide application in AA-contaminated areas.…”

Dietary exposure to aristolochic acids (AAs) through AA-tainted wheat has long been identified as one of the main causes of Balkan endemic nephropathy (BEN), a slowly progressive renal fibrotic disease affecting numerous residents of farming villages alongside tributaries of the Danube River. Only recently though have we begun to appreciate that AAs, released from the decay of a common weed Aristolochia clematitis, are contaminating farmland soil and groundwater of endemic areas. To reduce the risk of human exposure to this class of highly potent phytotoxins, it is imperative to develop remediation methods for AA-polluted water and arable soil. In this study, we explored the potential use of some commonly used phytoremediation plants for the phytoextraction of AAs from AA-contaminated water and soil. Among the tested plants, results showed that wheatgrass is highly efficient in extracting AAs from both contaminated water and soil and metabolizing them to the less toxic aristolactams. Furthermore, both the phytoextraction and plant metabolism efficiencies increased in an acidic environment, which is typical of endemic villages, highlighting the applicability of the developed method for affected areas.
