Chlorinated components in lime used in production contaminated citrus pulp pellets from Brazil.

In order to further understand the contamination of the citrus pulp pellets (CPP) that were exported to Europe in 1997 we examined both contaminated lime and CPP samples for the distribution of polychlorinated biphenyls (PCBs) and chlorinated benzenes (tri-hexa). Standard isotope dilution techniques were applied for all samples, which were analysed by selected ion monitoring high resolution GC-MS. Lime that is used in the production of CPP product is highly contaminated with PCBs and chlorobenzenes.
