This work aimed to detect changes in trace element chemical speciation sewage sludge (SS) after the ozonation process. The modified Community Bureau of Reference (BCR) sequential extraction procedure was performed determine elements SS To assess potential soil contamination with from process, risk assessment code (RAC) coefficient used. bioaccumulation factor (BAF) and translocation (TF) values...

An umbilical vein model was designed in which washed vein segments are filled with a reaction mixture containing factor VIIa, Ca(+)+, and a substrate, either 3H-factor IX or 3H-factor X. The vein wall provides the tissue factor (TF) for factor VIIa/TF complexes that activate the substrates as measured by activation peptide release. The model was developed to study TF induced on venous endotheli...

environmental pollution with heavy metals is a global disaster that is related tohuman activities. this study was conducted to determine the extent of heavy metalsaccumulation by plant species in lia industrial city (qazvin, iran) and to investigate theremediative capacity of native plant species grown in the contaminated soils. soil andindustrial wastewater sampling was done radially along tra...

Nerve growth factor (NGF) is a neurotrophic factor that is functional in the survival, maintenance and differentiation of nervous system cells. This protein has three subunits, of which the beta subunit has the main activity. Its structure consists of a cysteine knot motif made up of beta strands linked by disulfide bonds. It can be used as a therapeutic agent in the treatment of many diseases....

The Middle East is considered as one of the driest regions world and use municipal-treated wastewater (TWW) for agricultural purposes needed. aim this study was to evaluate effect continuous irrigation TWW in lemon orchards on accumulation heavy metals (HMs) soil, well their uptake translocation aerial parts trees. For purpose, two were selected be irrigated from different water sources: a tert...

Little information is available on As contamination dynamics in the soil-plant systems of wetlands. Total arsenic (As) in soil and plant samples from Suaeda salsa and Phragmites australis wetlands was measured in the Yellow River Estuary (YRE) in summer and autumn of 2007 to investigate the seasonal changes in As concentrations in different wetlands. The results showed that soil As levels great...

Effective biomonitoring strategies are essential for identifying and assessing the sources levels of contamination heavy metal pollutants in urban areas, given their negative impacts on human health environment. This study aimed to assess potential common weed, Trifolium pratense as a bioindicator various land uses with focus Cd, Cu, Cr, Ni, Pb. The results have shown that Cr Ni had high biocon...

There is a complex cadmium (Cd) and iron (Fe) interaction in soil. To explore the influences of Fe application on growth, Cd accumulation, antioxidant capacity poplar under exposure, Populus tremula × P. alba ‘717’ was treated with different concentrations (0 100 μM) (50 150 μM). In addition, root architecture, leaf chlorophyll content, enzyme activity were analyzed. The results showed that hig...

Selection of sunflower varieties with greater cadmium (Cd) tolerance and detecting physiological variation under different Cd concentrations are important to study the potential (Helianthus annuus L.) in phytoremediation Cd. The aim this was investigate among four (79−79, 363, 8361, ADT). Photosynthesis determined using a Li−6400 XT portable photosynthesis system. Inductively coupled plasma mas...

abstract nowadays, soil pollution with heavy metals has become a major problem which their accumulation in plants can directly or indirectly influence on animals and humans life. lead and cadmium are poisonous metals, with increasing the amount of these metals in environmental pollution; they will be increased in food chain significantly. in this research, three levels of cadmium (0, 100 and 20...
