A pot culture study was conducted to investigate the impact of applying humic acid functionalized bentonite (HA-B) on uptake heavy metals by spinach. When soil amended with 7.5 g kg-1 intercalated bentonite, there a significant improvement in plant growth. Specifically, growth increased 180.7%, 212%, and 231% during first, second, third cuttings, respectively. Additionally, concentration spinac...

tissue metal accumulations (gills, liver, kidney and muscle) in persian sturgeon (acipenser persicus) were compared folowing exposure to sublethal levels of waterborne cd (50, 400 and 1000 μg•l-1) after periods of 1, 2, 4 and 14 days. the obtained results indicate that at the end of 4 and 14 days of exposure, total tissue cadmium concentration followed the pattern: liver > gill > kidney > muscl...

Although inorganic and organic manures with high concentrations of heavy metals can lead to accumulation or contamination in soils, there are few reports on the effects long-term application swine green rice grains paddy soils. A field experiment, which was established 1990 soil Hangzhou, China, used investigate availability uptake by plant. The results showed that nitrogen, phosphorus potash (...

The levels of cadmium (Cd) in soil and commonly consumed tomato (Lycopersicon csculentum Miller) fruits grown around the industrial areas Dhaka Narsingdi districts Bangladesh were quantified compared with FAO/WHO (2003)safety limits. According to findings, order Cd concentration soils was found Textile > Pharmaceutical Tannary industry. (mg/l) ranged from 0.24 0.91 0.15 0.74, respectively. E...

Simple bioaccumulation models predict a monotonic increase in concentration with time until an equilibrium concentration is reached. However, unconsidered dynamics including deterministic oscillations occur if realistic time lags are incorporated. Stability criteria are provided for difference and differential forms of the simplest model. These criteria provide the means of identifying systems ...

The study discusses changes in lead contents soil and crops after application of compost fly ash. A three-year experiment was conducted on narrow-leaved lupine (Lupinus angustifolius L.), camelina (Camelina sativa L.) oat (Avena which were grown medium fertilised with or ash (FA). amounts various combinations evaluated using sequential (BCR analysis) single (DTPA solution) methods. total select...
