Radial oxygen loss (ROL) has been suggested to be a major process to protect plants exposed to the anaerobic by-products of soil anaerobiosis. The aim of the present study was to test the effects of root ROL from two submerged plants (Hydrilla verticillata and Vallisneria spiralis) on the rhizosphere oxygen profile and rhizosphere microarea. Phospholipid fatty acids (PLFAs) of sediment samples were used to characterize and quantify the microbial community. The results showed clearly that there were significant differences between the two plants in radial oxygen loss, which affected rhizosphere physicochemical parameters and the microbial community. Rhizosphere total biomass, bacteria, gram-positive bacteria, actinomycetes, and microbial diversity of V. spiralis were significantly higher than those of H. verticillata. The present study highlights root ROL as a key parameter affecting the microbial community of the rhizosphere microarea.

The high concentration of ferric (Fe 3+ ) in sample has interference on the determination of ferrous(Fe 2+ ) concentration by spectrophotometric method which 1, 10-phenanthroline is used to as chromogenic agent. Appropriate concentration of fluorine ion (F -) can complex Fe 3+ to eliminate interferences which the F -concentration is 13.3 time greater than that of Fe 3+ . The temperature and light do not affect the masking action of F -. Low temperature and dark conditions favour the stability of chromophoric complex. This method is suitable for determination iron species in the presence of high concentration of Fe 3+ in sample.

The advantages include sensitivity and the use of one ligand for several metals without the need for a specific chromophore. Aqueous solutions of Fe(II), Ni(II), 10Zn(II), Cu(II), Cr(III) and Cd(II) in the presence of excess 2,2'-bipyridyl (bipy) were analysed using SERS. Specific marker bands enabled the identification of each metal ion and the limit of detection for each metal ion was estimated. Two of the ions, Zn(II) and Cu(II), could be detected below the World Health Organisation's (WHO) recommended limits for drinking water at levels of 0.22 and 0.6 mg L -1 , respectively.
