Air pollution in Kenya
Gatebe, CK; Kwach, R; Njau, LN; Mukolwe, EA (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 ... -
Assessment of Ozone, Nitrogen Oxides, Air Particulate Matter in the Ambient Air of Nairobi city
Mangala, JM; Odhaimbo, GO; Kinyua, AM; Gatebe, CK; Maina, DM (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 ... -
The atmosphere, aerosols, trace gases and biogeochemical change in southern Africa : a regional integration : START Regional Syntheses
Tyson, PD; Gatebe, CK (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 ... -
Heavy metal analysis of suspended particulate matter (SPM) and other samples from some workplaces in Kenya
Kinyua, AM; Gatebe, CK; Mangala, MJ (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 ... -
Monitoring of suspended particulate matter (SPM), heavy metals and other parameters in some workplaces
Kinyua, AM; Gatebe, CK; Mangala, MJ; Korir, AK; Bartilol, S; Maina, DM; Mugera, WG; Kamau, GN; Chakaya, JM; Karama, M; Miungu, DM; Kitio, V (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 ... -
Nitrogen oxides, ozone and heavy metals analysis of suspended particulate matter (spm) of air in Nairobi, Kenya
Odhiambo, O; Kinyua, AM; Gatebe, CK (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 ... -
Sensitivity of off-nadir zenith angles to correlation between visible and near-infrared reflectance for use in remote sensing of aerosol over land
Gatebe, CK; King, MD; Tsay, Si-Chee; Ji, Q; Arnold, GT; Li, JY (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 ... -
A simple diffusion model for calculating concentrations from line sources in Nairobi
Gatebe, CK; Nganga, JK; Rao, MS; Kinyua, AM (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 ... -
Workplace monitoring and occupational health studies in Kenya using nuclear and related analytical techniques
Kinyua, AM; Gatebe, CK; Mangala, MJ; Maina, DM; Korir, AK; Bartilol, S (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 ...
