Rotation type was likely the main effective factor on variations of the soil DTPA-extractable Cd contents in some parts (eastern part of study region) and could explain some Cd variation. Total Cd concentrations had significant correlation with the total neutralizing value (p p p p p...
DTPA contents of all four metals were considerably high, and percentages of DTPA Pb and Cu in total contents were higher than those of DTPA Zn and Cd. There were significant correlations between total and DTPA contents of four trace metals. It indicated that DTPA extractable metals might be ...

caliginosa, and from 667.9 to 2645 mg Zn kg 1, 7.7 to 26.3 mg Cd kg 1, 0.5 to 37.9 mg Pb kg 1 and 16.0 to 37.6 mg Cu kg 1 in L. rubellus, respectively. Correlations between body loads in earthworms with either total or DTPA-extractable contents of soil metals were significant, ...
Nearly all diethylenetriaminepentaacetic acid (DTPA)-extractable metals (Fe, Zn, Cu, Cd, and Pb) were highest in the collection 4 yr after application,... CS White,SR Loftin,R Aguilar - 《Journal of Environmental Quality》 被引量: 176发表: 1997年 Magnetic resonance imaging agents Novel magn...
Mn and Zn content. 0.05 M EDTA extracted the highest quantity of Fe, Mn and Zn. The extractability of Cu was in the following order: EDTA pH 8.6>0.05 M EDTA>DTPA pH 7.3. Extractable Fe, Mn and Zn by different procedures were significantly correlated with each other. Therefore, All teste...

The current work aimed at investigating the distribution of total and DTPA-extractable Cd, Co, Cu, Pb, Ni and Zn in Kafr El-Sheikh Governorate, one of the greatest rice-producing regions in Egypt. The studied area covers 88709 ha between 31°01′ 30′′ to 31°25′ 05′′ N and 30...
This study investigated the influence of biochar on temperature, pH, organic matter (OM), seed germination index (GI), the fluorescent components of dissolved organic matter (DOM), and bioavailability of DTPA-extractable Cu and Cd during composting and analyzed the relation between DTPA-extractable ...
DTPA EXTRACTABLE METALSThe DTPA extractability of trace metals and their bioaccumulation by ryegrass ( Lolium perenne L.), grown on two soils treated with sewage sludge, were investigated in a greenhouse pot experiment over a period of 1 year following sludge application. The experiments were ...
