In a Belgian pilot study honey bee wax combs from ten hives were analyzed on the presence of almost 300 organochlorine and organophosphorous compounds by LC-MS/MS and GC-MS/MS. Traces of 18 pesticides were found and not a single sample was free of residues. The number of residues found per sample ranged from 3 to 13, and the pesticides found could be categorized as (1) pesticides for solely api...
Different agricultural residues were considered in this study for their ability to support cellulolytic enzyme production by Aspergillus niger. A total of eleven agricultural residues including finger millet hulls, sorghum hulls, soybean hulls, groundnut husk, banana peels, corn stalk, cassava peels, sugarcane bagasse, saw dust, rice straw and sheanut cake were subjected to three pretreatment (...
In the present work, a method for the analysis of the residues of chlorpyrifos and its toxic metabolite 3,5,6-trichloro-2-pyridinol (TCP) in agricultural soil and apples was developed. The residues of chlorpyrifos and TCP were extracted from agricultural soil and apple samples by shaking followed clean-up by liquid-liquid extraction (LLE) and solid-phase extraction (SPE) coupled with detection ...
Abstract Lignocellulose biomass is a unique renewable and sustainable source that can be used in energy generation, production of transport fuels chemical industries to replace petroleum-based resources. However, due its recalcitrance enzyme breakdown, it needs pre-treated prior processing. In this study, ultrasound assisted ozone was pre-treat the agricultural processing residues corn cob spel...
