Workplace monitoring and occupational health studies in Kenya using nuclear and related analytical techniques
(Institute Of Nuclear Science, University Of Nairobi, Kenya, 1997)Air pollution studies in Nairobi are indicating a rising trend in the particulate matter loading. The trend is mainly attributed to increased volume of motor vehicles, the physical change of the environment, agricultural ... -
Analysis of soil for trace elements along two highways of Kenya
(1998)For a long time, the toxicity of metals was considered as an occupational hazard. Industrialization, urbanization, increased vehicular traffic and use of fertilizers and pesticides in agriculture have resulted in increased ... -
The atmosphere, aerosols, trace gases and biogeochemical change in southern Africa : a regional integration : START Regional Syntheses
(2001)Attention is focused on temperature and rainfall changes occurring over the subcontinent of southern Africa, on atmospheric circulation and transport of aerosols and trace gases in the vertical and horizontal, and on ... -
Sensitivity of off-nadir zenith angles to correlation between visible and near-infrared reflectance for use in remote sensing of aerosol over land
(2002)Cloud absorption radiometer (CAR) multispectral and multiangular data, collected during the Smoke, Clouds, and Radiation-Brazil (SCAR-B) Experiment, was used to examine the ratio technique, the official method for remote ... -
Measurement of 222Rn concentration in Kenyan groundwater.
(1998)Groundwater samples from different parts of Kenya have been analyzed for their 222Rn concentrations. Samples were drawn from municipal supplies, springs, wells and bore holes in different geological terrains. In the analysis, ... -
Nitrogen oxides, ozone and heavy metals analysis of suspended particulate matter (spm) of air in Nairobi, Kenya
(2001)Motor vehicle emissions are a major source of air pollution in most urban centers. In Kenya, Nairobi city has the highest traffic density and is therefore a particular cause for concern due to the poor maintenance standards ... -
Trace element analysis of mineral and tap water samples using total reflection x-ray fluorescence (TXRF)
(2000)Results of trace element analysis by TXRF of tap water and various brands of bottled mineral water samples which are representative of local and imported brands sold in Nairobi are reported. The variation in elemental ... -
Monitoring of suspended particulate matter (SPM), heavy metals and other parameters in some workplaces
(2000)This report presents results of measurements of sound levels, chemical analysis of air particulate matter and soil samples from two factories in Nairobi. A preliminary assessment of suspended particulate matter (SPM) in a ... -
Heavy metal analysis of suspended particulate matter (SPM) and other samples from some workplaces in Kenya
(1998)Air pollution studies in Nairobi are indicating a rising trend in the particulate matter loading. The trend is mainly attributed to increased volume of motor vehicles, the physical change of the environment, agricultural ... -
The determination of levels of mercury, cadmium and lead in water samples from Naivasha area, Kenya
(1995)The analysis of mercury, cadmium and lead in water samples from different environments (Lake Naivasha, River Malewa boreholes and Olkaria geothermal wells) in Naivasha region and their possible origins are reported. The ... -
Prospects of Establishing Food Irradiation Facilities in Kenya
(1997)A national project of food irradiation in the country is being proposed. At present there are no facilities for food irradiation (and food irradiation research) in Kenya. This report is therefore largely comparative ... -
Assessment of Ozone, Nitrogen Oxides, Air Particulate Matter in the Ambient Air of Nairobi city
(2006)World wide, more than 1.1 billion people live in urban centres that are highly polluted by industrial and other human activities. Among the most common and most virulent air pollutants are sulphur dioxide,suspended particulate ... -
Air pollution in Kenya
(1993)Energy Dispersive X-ray Fluorescence (EXDRF) analysis of aerosol samples in Nairobi is presented. Results show that elemental concentrations is of the order of 10^ to lO"10 \igfm^ for most elements analyzed. The total ... -
EDXRF analysis of local and imported pica soil samples
(EAST AFRICAN JOURNAL OF SCIENCE I Volume 3 -Part 1 June 2001, 2001)Several studies have implicated trace metal metabolism with some human diseases. Energy Dispersive X-Ray Fluorescence(EDXRF)method was used to analyse pica soil samples, which are consumed by some pregnant mothers in ... -
A simple diffusion model for calculating concentrations from line sources in Nairobi
(1994)A simple physically realistic model is used for estimating carbon monoxide(CO) from highway in Nairobi using motor vehicle data for 1989. The year 1989 was chosen because it was the most recent year with motor vehicle count ... -
Pixe analysis of trace elements in tissues of rats treated with anticonvulsants
(1987)Several lines of evidence implicate metals in epilepsy. Anticonvulsant drugs are noted to alter levels of metals in humans and animals. PIXE analysis was used to investigate effects of three anticonvulsant drugs on tissue ...
