To better explore the capacity for any known lawn plant, like Axonopus compressus, for landscaping, which ultimately considers its phytoremediative capacities, the presented study investigated growth and phytoremediative capacity of the test plant in a heavy metal-polluted soil. Experimental soils were polluted with copper (as CuSO4) in 4 different concentration; 100, 200, 300 and 400mg/kg. Copper-polluted soils and control soils were sown with tillers of Axonopus compressus. The study was observed for 3 months. Afterwards, results showed that plant growth was adversely impacted as concentration of Cu increased. This reduction intensified as Cu concentration increased. Accumulation of Cu in leaves, stem, sheath, and root of Axonopus compressus in Cu-polluted soil as well as residual soil metal concentration after 3 months of exposure was reported. Leaf accumulation was 18.06-61.08mg/kg, whereas stem accumulations were 13.27-50.87mg/kg. Comparatively, there were differences in the phytoaccumulations of metal across the plant organs. The root had better accumulation levels. However, at higher soil metal levels, this trend was somewhat distorted; the highest accumulation being in the leaf (61.08mg/kg) in the 200mg Cu/kg soil treatment level, when compared with stem (35.15mg/kg), sheath (23.77mg/kg), and root (40.99mg/kg). This suggests perhaps, that the preferred organ of metal deposition depend on the soil concentration of the polluting metal. Antioxidant composition of the leaves of metal-exposed plants showed that contents of CAT, SOD, MDA and to copherol significantly (p<0.01) increased. Significant increases in CAT and SOD levels in the roots of the test plant implied that metal effects necessitated the heightened activity of the enzymes in question. Root CAT was 17.01mol/g tissue in the control, compared to 21.05-23.74mol/g tissue in the Cu-exposed plants. SOD contents of root was 49.33mol/g tissue in the 400mg Cu/kg soil treatments compared to 30.12mol/g tissue in the control. Minimal changes (p>0.05) in peroxidase and ascorbate concentrations however were. This study has established that Axonopus compressus has the capacity to withstand the deleterious effects of copper contamination and the capability to remove copper from polluted soils, and hence a good candidate for landscaping.<#LINE#>Garbisu C. and Alkorta I.

Repairing mechanisms for theses impaired processes afford promising treatment strategies for these kinds of disorders. Alpha-7 nicotinic acetylcholine receptor is a sub type of nicotinic acetylcholine receptor which has been recognized as one of the most useful drug target for the treatment of nervous system associated disorders. Molecular docking analyses have been carried out to detect any possible secondary metabolites present in Ashwagandharishta that could act as agonists of alpha-7 nicotinic acetylcholine receptor. According these computational findings, it has been found that two phytochemicals; anaferine and anahygrineexhibit promising agonistic activity towards the receptor. Thus anaferine and anahygrine have high possibility to serve as alpha-7nAChR agonists which demonstrate potential drug action towards memory related disorders.<#LINE#>Wilson G.G.

In conducting this study, monthly sampling was doing at three different stations in this estuary, a collection of 36 samples over the study period. The extracts of these hydrocarbons, obtained from these samples according to MA.400-HAP 1.1 standard, were assayed by high performance liquid chromatography (HPLC) with UV/fluorescence detectors coupled to a GC-MS mass spectrometer. The results show the absence of Benzo (g,h,i) Perylene and Indeno (1,2,3-cd) Pyrene in these entities over the entire study period. The other six polycyclic aromatic hydrocarbons, with a strong seasonal dynamics, were detected in these substrates only in a few seasons and, this with relatively high concentrations (ranging between 0.020 &plusmn; 0.001 and 123.40 &plusmn; 6.17mg/kg per dry weight). As a result, significant seasonal mean values of &#931;8PAHs (ranging between 0.020 &plusmn; 0.001 and 158.07 &plusmn; 2.13mg/Kg per dry weight) with its annual mean value of 48.08 &plusmn; 0.83mg/kg per dry weight, were observed on this period. Thus, the superficial sediments from Vridi Canal are heavily contaminated by polycyclic aromatic hydrocarbons. The immediate consequence of this situation is the advanced state of degradation of Vridi canal, with very high ecological risks, as illustrated by four marine sediment quality guidelines (Apparent Effect Threshold Approach, Consensus Based Sediment Quality Guidelines, Toxic BaP equivalent quotient, Hazard quotients) used in this study. This pollution is of petrogenic origin, essentially of the only and great oil-producing industrial area of C&Ocirc;te d\'Ivoire, located near of this ecosystem.<#LINE#>SCS (2009).@Texte et Annexes telle qu&prime;amend&eacute;e en 2009.

Data, generated from 2007-2009 at 18 study stations, were statistically partitioned using HAC, consolidated with the use of the k-means algorithm. That generated classification of the stations in two (02) groups. Group 1 is abnormally nitrogenous and has seasonal stratifications. This group consists of clusters 1 and 2 (stations 13, 10, 9 and 8; then 1, 12, 17 and 18 respectively) located in South-Aby and Ehy. Group 2 is more abnormal in nutrient than metal impacted. It is significantly influenced by nitrogen salts, phosphorus and mobilizable cadmium. This group is composed of clusters 3-7 which are mainly located in the lagoon entities Aby Nord and Tendo. In fact, beside the resuspension of the bituminous lagoon bottoms, the South-Aby and Ehy entities would have physical and chemical characteristics favourable to the human use of the Aby lagoon waters.<#LINE#>Xu Y. and Morel F.M.

Results obtained showed the presence of alcohol (OH-), alkane (C-C) and alkene (C=C) in all three plants as indicated by the peaks at wavelength ranges of 3600 - 3200cm-1, 2935 - 2915cm-1 and  1680- 1620cm-1 respectively. Tertiary alcohol and phenol were also present in all three plants as indicated in the wavelength ranges of 1420 - 1330cm-1 and 1390 - 1310cm-1 respectively. Carbonyl (C=O) and Nitro (N=O) functional groups were exclusively found in Bitter leaf at wavelength ranges of 1740 - 1715cm-1 and 1550 - 1500 cm-1 respectively while wavelength ranges of 1190 - 1130cm-1 and 1090 - 1020cm-1 indicates the presence of secondary and primary amines exclusively present in Bitter leaf and Vetiver grass. Functional groups such as sulfoxide (S=O) and iodo compounds (C-I) as indicated at wavelength ranges of 1070 - 1030cm-1 and 600 - 500cm-1 were present in Vetiver grass. The higher the molecular polarizability of the plants which is a function of the polar functional groups present, the higher the adsorption capacity of the plant. The presence of carbonyl functional groups in Bitter leaf will give it an advantage in terms of adsorption capacity compared to Water leaf and Vetiver grass because carbonyl functional groups are highly polarized due to their ability to form hydrogen bond as well as the presence of high dipole moments orchestrated by two electronegative atoms.<#LINE#>Ebuehi O.A.T., Abibo I.B., Shekwolo P.D., Sigismund K.

Conventional methods for the elimination of toxic metals has disadvantages such as high reagent requirement and generation of toxic sludge etc. Toxic substances may be resulting from metal plating, mining operations, sludge disposal, refining ores, pesticides, batteries. Hence, economic and eco-friendly techniques are requisite for water treatment. Biosorption is an affordable and effective technical process applied to eliminate pollutants from water. This technology is efficient cost effectual and sustainable technology. In this review paper investigate sorption technology for the sequestration of pollutants.<#LINE#>Lasat M.M.
