in this study, the effect of four citrus rootstocks {sour orange (citrus aurantium), bakraeii (c. reticulata × c. aurantium, mexican lime (c. aurantifolia) and volkamerlemon (c. volkameriana)} on orlando tangelo leaf chlorophyll content and mineral element concentrations (n, p, k, ca, na, mg, fe, zn, mn, cl, cu, and b) have been evaluated in completely randomized design with four replications. ...

pollution of water and soils by heavy metals is an emerging problem in industrialized countries.the present study was conducted to investigate the heavy metals concentration in water and sedimentsamples from ship breaking sites of sitakunda to assess the potential ecological risk posed by heavy metalusing different methods. heavy metals concentration was analyzed by atomic absorption spectrosco...

one of the most paramount processes that play a considerable role in reducing the concentration of heavy metals during estuarine mixing is flocculation. not only does such a process cause a huge percentage of metals to come into the particulate phase, but also it provides ample nutrients for the aquatic life. in the present study, impact of such factors as salinity, ph and do on flocculation of...

Analyses of food chains supporting isolated clusters of sporadic TSEs (CWD in N Colorado, scrapie in Iceland, CJD in Slovakia) demonstrate a consistent 2 1/2+ fold greater concentration of the pro-oxidant divalent cation, manganese (Mn), in relation to normal levels recorded in adjoining TSE-free localities. Deficiencies of the antioxidant co factors Cu/Se/Zn/Fe and Mg, P and Na were also consi...

the study aimed to come up with a list of specific macroalgae species, which could be used to biomonitor specific metal elements in the coastal waters of east africa. water extraction, edta, aqua regia extraction and optimized bcr 3-step sequential extracts were used to mimic bioavailable metals under various environmental conditions. the results indicated that ulva lactuca could be used as a b...

Preeclampsia complicates 2-8% of all pregnancies and is one of the leading causes of maternal mortality and pre-term delivery in world. In concern to the increasing number of preeclamptic cases and lack of data about the interrelation between levels of trace elements and preeclampsia, we conducted a hospital based case-control study to assess the risk of preeclampsia in relation to concentratio...

Genotoxicity of Cu and Zn was assessed by use of the micronucleus (MN) test on Vicia faba roots. Plants were exposed to various leachates of raw and anaerobically digested pig slurry, with maximum total concentrations of 200microM Cu and 600microM Zn. The results indicated stabilisation of the organic matter during anaerobic digestion of the slurry and bioconversion of some phytotoxic organic c...

The objective of this study was to investigate the concentration and spatial distribution patterns of six potentially toxic heavy metal elements (Mn, Zn, Cr, Pb, Cu and Ni) in bus station dusts in the Xifeng district of Gansu province, NW China. The contents were analyzed for Mn, Zn, Cr, Pb, Cu and Ni by using S8 TIGER Brochures wavelength dispersive X-ray fluorescence spectrometry. Geoaccumula...
