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 ...
Effect of anthropogenic activities on physico-chemical parameters and benthic macroinvertebrates of Mara river tributaries, Kenya
(2014)
The impact of anthropogenic activities within Bomet and Mulot towns on
water quality of Amala and Nyangores tributaries of Mara River, Kenya
was assessed using a combination of solid waste, physico-chemical
parameters ...
Influence of Water Availability on Food Crop Production in Semi-Arid Areas in Kibwezi District, Makueni County, Kenya
(Arts Humanit, 2015)
Ecosystems provide essential services like water regulation and other processes which sustain and fulfill human life by directly or indirectly supporting humans‟ survival and quality of life. However, there is insufficient ...
Intensity of farmland cultivated and soil bulk density in different physiographic units in Nyakach district
(Journal Of Humanities And Social Science, 2014)
A number of scholars agree that frequent cultivation raises soil bulk density through compaction and destruction of soil structure. However, no research has been conducted to establish how the intensity of farmland cultivated ...
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 ...
Determinants of aboveground carbon offset additionality in plantation forests in a moist tropical forest in western Kenya
(Elsevier, 2016-04-01)
Few studies have attempted to identify factors that contribute to aboveground carbon offset additionality in forest restoration planting in the tropics. Moreover, those that have compared aboveground carbon offset potential ...
Effects of Locations On-and Off-Epigeal Termitaria on Vegetation Lifeforms in Katolo Sub-Location of Kisumu County, Kenya
(SCIRJ, 2017)
Epigeal termitaria host richer vegetation assemblages ascribed partly to their elevated nutrients levels in savannah
ecosystems. However, elaborate quantitative description of how abundance of various vegetation lifeforms ...
Vitamin D status in healthy black African adults at a tertiary hospital in Nairobi, Kenya: a cross sectional study
(BioMed Central, 2018-12-01)
Vitamin D has been known since the twentieth Century for its benefits in bone health. Recent observational studies have demonstrated its benefits in infectious diseases such as tuberculosis and non-communicable diseases ...
