aggregate stability is an important soil property because it dictates how strongly a soil can resist water erosion. the objectives in this study were: (1) to compare the stability of six soil aggregate size fractions, primarily to determine if aggregate stability varies with aggregate size, and (2) to determine with which aggregate size fraction the stability of most soils would be different fr...

A new blocked mutant of Aspergillus parasiticus produces no detectable aflatoxin B1, but accumulates several polyhydroxyanthraquinones. One of these pigments was identified as averantin. This is the first report of its formation by A. parasiticus. Radiotracer studies with [14C]averantin showed that 15.3% of label from averantin was incorporated into aflatoxin B1. This incorporation was blocked ...

Background: Pesticide use for fruits and vegetable production in Uganda may result presence of residues on produce which pose health risks to consumers. This research aimed at conducting a risk assessment pesticide vegetables Kampala Metropolitan Area, Uganda. Method: Pesticides were measured 160 samples analysed using liquid chromatography-tandem mass spectrometry. Fruit consumption informatio...

In order to ensure edible safety, more regard has been paid to pesticide contamination on agricultural product. Conventional techniques are used to measure pesticide contamination. However, the conventional analyses are not possible because of their destructive characteristic and the limitation of time and labor. Spectral technique can provide a rapid, nondestructive means to assess quality and...
