摘要: In 1997, the Polychlorinated dibenzo-para-dioxin (PCDD)/Polychlorinated dibenzofuran (PCDF) concentrations in dairy products Germany and other European countries increased. The PCDD/PCDF source was contaminated lime used Brazilian citrus pulp pellets. mined from an industrial dump site. However, detailed origin of PCDD/PCDFs not revealed. This paper investigates contamination describes link between milk dumpsite a chlorine/organochlorine industry lime. stem mining at corporate landfill Solvay Indupa Sao Paulo. for 40 years deposition production residues closed 1996. factory operated/operates least two processes with potentially high releases namely oxychlorination process ethylene dichloride (EDC) chlor-alkali process. main landfilled waste (1.4 million tons) vinyl chloride monomer (via acetylene process) along processes. fingerprint revealed that most samples chemical showed EDC pattern characteristic octachlorodibenzofuran dominance.
