![]() Anthracene is known to cause damage to human skin and arsenic has been linked to lung and liver cancer. The two aromatic hydrocarbons were neither detected in the shoot nor root tissue of the ridge gourd, which suggests that phytostimulation may be the most likely mechanism by which these hydrocarbons were removed from soil.Īssessing Anthracene and Arsenic Contamination within Buffalo River Sedimentsįull Text Available Anthracene and arsenic contamination concentrations at various depths in the Buffalo River were analyzed in this study. In contrast, 27.7-48.2% and 46.9-73.8% of anthracene and fluoranthene respectively, spiked alone or together, remained in the control un-planted soil during the same period. Only 0.5-1.8% and 3.1-14.1% of anthracene and fluoranthene respectively were detected in planted soil on day 45. Planting of ridge gourd was more effective in decreasing the amount of anthracene and fluoranthene from soil than un-planted control during the 45-day experiment. Fluoranthene spiked either alone or together with anthracene was toxic to the plant as shown by significantly reduced shoot and root growth, especiall y on day 45 after transplantation. The ridge gourd grew normally in anthracene-contaminated soil based on assessment of shoot growth at the end of the experiment. When spiked together, the initial concentration of each hydrocarbon was 50 mg kg -1. The i nitial concentration of anthracene or fluoranthene was 100 mg kg -1 when each was spiked alone. Phytoremediation of anthracene- and fluoranthene contaminated soil by Luffa acutangulaĭirectory of Open Access Journals (Sweden)įull Text Available Phytoremediation of soil contaminated with anthracene and fluoranthene, either alone or together, by ridge gourd (Luffa acutangula was investigated through laboratory pot experiments in a greenhouse for 45 days. ![]() The rest of the fungi degraded anthracene to a lesser extent (cork itself, could be used as an efficient degrader of PAH-contaminated cork. After 61 days of incubation, approximately 86%, 40%, and 38% of the initial concentration of anthracene (i.e., 100 µM) was degraded by P. Results show that all the fungi tested degraded anthracene. lacteus were also identified by GC-MS and a metabolic pathway was proposed for P. The degradation products of anthracene by P. Anthracene degradation by all fungi was examined in solid-phase cultures after 0, 16, 30 and 61 days. For this purpose, the degradation efficiency of anthracene by three ligninolytic white-rot fungi (Phanerochaete chrysosporium, Irpex lacteus and Pleurotus ostreatus) and three non-ligninolytic fungi which are found in the cork itself (Aspergillus niger, Penicillium simplicissimum and Mucor racemosus) are compared. Biodegradation of contaminated cork using filamentous fungi could be a good alternative for detoxifying cork to facilitate its final processing. The efficiency of cork waste in adsorbing aqueous polycyclic aromatic hydrocarbons (PAHs) has been previously reported.

An alternate synthesis from 3,4-dihydrobenz anthracene 1-(2H)- one was used for the preparation of 1- and 2- 2 H BAs and DMBAs. Lithium aluminum deuteride reduction gave the 2 H-DMBAs. The 2-, 3-, and 4-bromo-7,12-dimethylbenz anthracenes (DMBAs) were prepared from the bromo BADs in moderate yield by the classical Grignard procedure. Lithiation with t-butyllithium followed by quenching with deuterium oxide gave the specifically 2 H-labeled BAs with deuterium incorporations of > 95%. The corresponding bromobenz anthracenes (BAs) were prepared by aluminum tricyclohexoxide reduction of the diones. The 2 + 4 cycloaddition reaction of 1,4-naphthoquinone and substituted styrenes was used to prepare 1-, 2-, 3-, and 4-bromobenz anthracene-7,12-diones (BADs). The preparation of specifically 2H-labeled benz(a) anthracenes and 7,12-dimethylbenz(a) anthracenes This undergoes an electron-induced topotactic conversion to anthracene, and the study of this reaction using low temperature TEM enabled the identification of separate stages in the conversion and the elucidation of probable mechanistic routes. Thomas, J.M.Ī study was made of single crystals of di-para anthracene, the product of photodimerisation of anthracene.
