Carbofuran and its Toxic Metabolites Provide Forensic Evidence for Furadan Exposure in Vultures (Gyps africanus ) in Kenya

Otieno, Peter O; Lalah, Joseph O; Virani, Munir; Jondiko, Isaac O; Schramm, Karl-Werner (2010)

Forensic analysis of carbofuran residues in weathered tissue samples for evidence of Furadan exposure in vultures (Gps africanus) by HPLC gave concentration (mg/Kg dry tissue weight) ranges of bdl – 0.07 (carbofuran), bdl ...
Carbofuran use and abuse in Kenya: residues in soils, plants, water courses and the African white-backed vultures (Gyps africanus ) found dead

Otieno, Peter O; Lalah, Joseph O; Virani, Munir; Jondiko, Isaac O; Schramm, Karl-Werner (2011)

The increasing number of incidences of alleged wildlife poisoning with Furadan in Kenya has sparked off a strong lobby fronted by wildlife conservationists against Furadan use in the country and prompted this study. The ...
Impacts of climate-induced changes on the distribution of pesticides residues in water and sediment of Lake Naivasha, Kenya

Otieno, Peter O; Owuor, P. Okinda; Lalah, Joseph O; Pfister, Gerd; Schramm, Karl-Werner (2013)

This study reports evidence of increased chlorpyrifos contamination in sediment and water in Lake Naivasha following its intensive application in the horticultural farms in the catchment area. Analytical results show that ...
Soil and water contamination with carbofuran residues in agricultural farmlands in Kenya following the application of the technical formulation Furadan

Otieno, Peter O; Lalah, Joseph O; Virani, Munir; Jondiko, Isaac O; Schramm, Karl-Werner (2010)
Soil and water contamination with carbofuran residues in agricultural farmlands in Kenya following the application of the technical formulation Furadan

Otieno, Peter O; Lalah, Joseph O; Viranib, Munir; Schramm, Karl-Werner; Jondiko, Isaac O (2010)

This study was undertaken to determine the concentrations of carbofuran residues in water, soil and plant samples from selected sites in the farmlands in Kenya and to demonstrate the impact of Furadan use on the local ...
Spatial Distribution and Temporal Trend in Concentration of Carbofuran, Diazinon and Chlorpyrifos Ethyl Residues in Sediment and Water in Lake Naivasha, Kenya

Otieno, Peter O; Schramm, Karl-Werner; Pfister, Gerd; Lalah, Joseph O; Ojwach, Stephen O; Virani, Munir (2012)

Chlorpyrifos ethyl was found to be widely distributed in water and sediment in Lake Naivasha. Higher levels were reported in sediment (11.2–30.0 ng g−1 dry weight (dw) in wet season than in dry season (4.7–17.4 ng g−1 dw). ...
