The development and application of two methods for determining bromate in bread are described. A gas chromatographic (GC) method which relied on the formation of a volatile derivative of bromate gave a detection limit of 12 μg/kg. Duplicate analyses agreed well but recovery from breads spiked with bromate were low and averaged 30% for brown bread and 42% for white bread. Further studies indicated that this was caused by the derivatization reaction being suppressed by components of the sample and reagents used in their preparation.
Does rural fuelwood use and more generally rural biomass use cause forest degradation? This question has been debated in scientific and policy circles. The author presents a framework for defining degradation and sustainable use of forests that might help clarify some of the confusion.
