The efficiency of organics and nitrogen removal from municipal landfill leachate in activated sludge operated as single and two-stage SBR were investigated. Leachate from mature landfills are characterized by high N/COD ratio (> 0.5). In single activated sludge system at the hydraulic retention time (HRT) 3d and at methanol dosage 8 mg COD/mg NNO3 complete ammonium nitrogen removal was obtained. Ammonium concentration in the effluent was 0.15 mg NNH4/dm3 and nitrate - 23.5 mg NNO3/dm3 . At the hydraulic retention time 2d, nitrate nitrogen concentration in the effluent decreased to 2.79 mg NNO3/dm3. The concentration of ammonium nitrogen was 0.35 mg NNH4/dm3. However, a sporadically high concentration of ammonium appears. In a two-stage SBR system, HRT 2d was sufficient to achieve complete nitrification. In the effluent ammonium and nitrate concentrations were 0.08 mgNNH4/dm3 and 320 mgNNO3/dm3, respectively. In the anoxic reactor at HRT 1d and methanol dosage 3.6 mg COD/mg NNO3 complete denitrification was obtained. Raw leachate contained specific hazardous organics, among others BTEX (175.8 µg/dm3), chloroorganics (55.7 µg/dm3), chlorobenzenes (0.75 µg/dm3) and PAHs (1.97 µg/dm3). In the effluent from single and two-stage SBR systems chloroorganics and chlorobenzenes were not detected. BTEX and PAH concentrations in the effluent from two-stage system were adequately 2-fold and 2.1-fold lower in comparison to a single one. Besides, the effluent from two-stage SBR systems did not contain benzo(b)fluoranthene, benzo(k)fluoranthene, benzo(a)pyrene and indeno(1,2,3-cd)pyrene.

The aim of this study was to investigate efficiency of ammonium nitrogen removal from municipal landfill leachate in activated sludge in two-stage SBR reactors. Treated leachate contains low concentrations of organic substances measured as chemical oxygen demand (COD) - 757 mg O2/dm3 and high concentrations of ammonium - 362 mgNNH4/dm3. Nitrification was studied in two parallel, aerated SBR reactors with two different hydraulic retention times (HRT), 3 and 2 days, respectively. We have found that 2 days HRT was sufficient to achieve complete nitrification. In the effluent ammonium, nitrite and nitrate nitrogen concentrations were 0.08 mgN NH4/dm3, 0.04 mgN NO2/dm3 and 320 mgN NO3 /dm3, respectively. The ammonium nitrogen removal rate was 20.2 mgN NH4 /dm3.h. The effluent from aerobic reactors (HRT 2 days) was fed to the anoxic SBR reactors. An external carbon source (methanol) was added to promote denitrification. In the anoxic reactor, at a methanol dosage 3.6 mg COD/mg N NO3 and HRT of 1 day complete denitrification was achieve with nitrate nitrogen residual concentrations of 0.9 mgNNO3/dm3. The maximum denitrification rate was 48.4 mgN NOx/dm3.h. The highest values of the yield methanol coefficient Y m/N-NOx were determined for dosages 3.6 mg COD/mg NNO3 and 5.4 mg COD/mg NNO3, the lowest for 1.8 mg COD/mg NNO3.

Exposure to environmental pollutants often leads to an upsurge in the production of reactive oxygen species (ROS). ROS oxidize cellular fatty acids to produce lipid peroxyl radicals, subsequently transformed into lipid peroxides, which decrease membrane fluidity and increase the activity of various enzymes implicated in degenerative diseases and cancer formation. Edible plants that contain exogenous compounds like curcumeroid, β-carotene, turmeric, and so on, protect the aerobic cells from oxidation of free radicals. This study thus evaluates antioxidant and antimutagenic activities of ethyl acetate, aqueous and methanolic fractions of Holarrhena floribunda leaves. Inhibitory activities of the ethyl acetate fraction on Fe2+-induced lipid peroxidation in hen egg yolk; rat liver and brain tissues were also evaluated. The Allium cepa root assay was used to evaluate antimutagenic activity. Results showed that the ethyl acetate scavenged DPPH, OH•, and •O2- much stronger than other fractions, as evidenced by its lowest respective IC50 values. All the fractions displayed antimutagenic activities against cyclophosphamide-induced chromosomal aberrations. Likewise, all the fractions induced a reduction in mitotic index, a hallmark of cytotoxicity in the root meristem of Allium cepa. The decrease in mitotic index was most profound for the ethyl acetate fraction, which also demonstrated a significant lipid peroxidation inhibitory activity in the liver and brain homogenates, but not in egg yolk, compared with the ascorbic acid standard. In general, the results suggest that the ethyl acetate fraction might contain beneficial phytochemicals that should be explored as novel candidates for preclinical drug development.

Oil seed rape seedlings which had been treated with 10-30 % methanol grew faster, their yield of fresh matter exceeded that of untreated control plants by 102 %, of dry matter by 80 %. Although methanol did not affect the content of chlorophyll or carotene in the leaves, the overall pigment yield grew with the dry matter of one seedling. The biomass of rape leaves which had been sprayed with 10 or 20 % methanol solutions was by 50-90% higher as compared to untreated plants. The activity of some enzymes (nitrate reductase and alkaline phosphatase) also increased in methanol treated plants.

There is a worldwide search for the safe, effective and eco-friendly compounds of plant origin to combat the weed species and other pests which are responsible for the great impact on the growth and productivity of agricultural crops. In this present study, a comparison was made to evaluate the phytotoxicity potential of sequentially extracted solvent (hexane, ethyl-acetate, methanol) extracts of Parthenium hysterophorus L. (aerial parts) in vitro through bench-top seed germination assay (Vigna radiata L.). One-way analysis of variance (ANOVA) followed by Duncan’s multiple range test (DMRT) were done for statistical analysis of the data. The study reveals that germination, growth and vigour was significantly (P<0.05) reduced by ethyl-acetate and methanol extracts. The present study concluded that phytotoxicity of ethylacetate and methanolic crude extracts of Parthenium hysterophorus could be exploited as potential bioherbicide for future weed management programme and the development of bioherbicide for commercial use.

Methanol oxidation in vivo to formaldehyde and next to formate, which takes place mainly in the liver, is accompanied by free radicals generation. The goal of this paper is to desribe the effect of vitamin E derivative (U83836E) on rat liver cell membranes during methanol intoxication (3.0 g/kg body weight). This study has been concerned with measurement of lipid peroxidation and surface charge density of liver cells and activity of lysosomal enzyme - cathepsin B - in cytosol of liver cells and the blood serum. An ultrastructural study of liver cells has also been conducted. It has been proven that methanol administration causes an increase in lipid peroxidation products (by 33%) as well as in surface charge density (by 64%) of the liver cells. This might have resulted from the membrane liver cell damage visible in the electron microscope and in leak of cathepsin B into cytosol (increase in activity by 28%) as well as the leak of cathepsin B from cytosol into the blood (increase in serum activity by 27%). Administration of U83836E to rats intoxicated with methanol partially prevented the above changes. Obtained results suggest that U83836E acts as an effective antioxidant in methanol intoxication.
