Enhanced soil washing process for the remediation of PBDEs/Pb/Cd-contaminated electronic waste site with carboxymethyl chitosan in a sunflower oil–water solvent system and …
(Springer Berlin Heidelberg, 2015-02-01)
An innovative ex situ soil washing technology was developed to remediate polybrominated diphenyl ethers (PBDEs) and heavy metals in an electronic waste site. Elevated temperature (50 °C) in combination with ultrasonication ...
Understanding yields in alley cropping maize (Zea Mays L.) and Cassia siamea Lam. under semi-arid conditions in Machakos, Eastern Kenya
(IOS Press, 2001-01-01)
Six seasons of experiments in Machakos, Kenya, revealed that above about 150 mm of rainfall, maize yields per row in alley cropped "replacement" agroforestry (AF) plots, of Cassia siamea Lam. and maize (Zea mays, cv. ...
Bioavailability assessment of hexachlorobenzene in soil as affected by wheat straw biochar
(Elsevier, 2012-05-30)
Biochar incorporation with soil could increase sorption of organic contaminants, thereby reducing their bioavailability. In this study, the effects of wheat straw biochar on the sorption, dissipation and bioavailability ...
Extracellular polymeric substances enhanced mass transfer of polycyclic aromatic hydrocarbons in the two-liquid-phase system for biodegradation
(Springer-Verlag, 2011-05-01)
The objective was to elucidate the role of extracellular polymeric substances (EPS) in biodegradation of polycyclic aromatic hydrocarbons in two-liquid-phase system (TLPs). Therefore, biodegradation of phenanthrene (PHE) ...
Improved biodegradation of 1, 2, 4-trichlorobenzene by adapted microorganisms in agricultural soil and in soil suspension cultures
(Elsevier, 2011-08-01)
Inoculating soil with an adapted microbial community is a more effective bioaugmentation approach than inoculation with pure strains in bioremediation. However, information on the potential of different inocula from sites ...
Improved biodegradation of 1,2,4-trichlorobenzene by adapted microorganisms in agricultural soil and in soil suspension cultures
(Pedosphere, 2011)
Inoculating soil with an adapted microbial community is a more effective bioaugmentation approach than inoculation with pure strains in bioremediation. However, information on the potential of different inocula from sites ...
Effects of autoclaving and mercuric chloride sterilization on PAHs dissipation in a two-liquid-phase soil slurry
(Elsevier, 2011-02-01)
A two-liquid-phase (TLP) soil slurry system was employed to quantify the efficiencies of autoclaving and mercuric chloride sterilization in the dissipation of polycyclic aromatic hydrocarbons (PAHs). The fates of 11 PAHs ...
Enhanced microbial degradation of humin-bound phenanthrene in a two-liquid-phase system
(Elsevier, 2011-02-28)
Humin, the main component of soil organic matter, greatly influences the nonlinear sorption and desorption hysteresis of polycyclic aromatic hydrocarbons (PAHs) in soil. However, little is known about the bioavailability ...
Chemical extraction to assess the bioavailability of chlorobenzenes in soil with different aging periods
(Springer-Verlag, 2011-12-01)
Bioavailability is mainly influenced by aging and desorption of contaminants in soil. The purpose of this study was to investigate the desorption kinetics of chlorobenzenes (CBs) in soil and to investigate whether chemical ...
Effects of physiographic units on the relationship between cropping frequency and level of soil erosion in Nyakach District, Kenya.
(International Journal of Scientific & Technology Research, 2014)
A number of scholars agree that farms which are cropped more frequently tend to exhibit lower levels of soil erosion than those that are cropped less frequently or left fallow. However, the effects of physiographic units ...
