Abstract EN
A field study was conducted in the summer season of 2017 in the Agricultural Experimental Station of Desert
Research Center (D R C), Wadi Suder, South Sinai, to evaluate the effect of sewage sludge on soil albedo, evaporation
and plant transpiration and to study the potential impact of transpiration and albedo on heavy metals mobility factors.
In
general, adding sewage sludge to calcareous soil increase soil organic matter and soil Whatever, transpiration correlates
with plant lifetime, therefore it increased as life time increase.
The accumulation of elements was generally higher in the
root as compared by shoot and grains.
The enrichment factor (EF) of Zn, Cu, pb and Cd increased by increasing sewage
sludge application rates and reached to 41, 62, 87 and 240% for Zn, Cu, Pb and Cd, respectively.
Concerning the effect of
soil albedo which decreases as increasing soil organic matter and sorghum lifetime, the last same percents of increasing in
enrichment factors (EF) ratio were achieved by decreasing soil albedo.
The data of bioaccumulation factor (BF) revealed
that elevated transpiration led to the increase of metal uptake and bioaccumulation factors of the studied heavy metals, the
concentration ratio reached 41, 46, 41 and 52% for Zn, Cu, Pb and Cd, respectively.
Meantime, BF ratios reached 54, 58,
59 and 53% for the previous sequence of metals.
Transpiration show a non-significant relation with Zn transport, also the
negative relation achieved for Cu and Cd while Pb increased by increasing transpiration.
Translocation factors values of
heavy metals reach 0.57, 0.42, 0.58 and 0.19 for Zn, Cu, Pb and Cd, respectively.
Finally, plants with a high BF and low
TF have the potential and ability to sequestrate most contaminants from sludge amended soil in roots consequently
prevent reaching to the beneficial part of plant.
