Aquatic photodegradation of polychlorinated dibenzofurans: rates and photoproduct analysis
Article Abstract:
The rates of aqueous photolysis of two toxic polychlorinated dibenzofuran (PCDF) congeners, 2378-T4 CDF and 23478-P5CDF, were determined using a xenon light source and under sunlight conditions. The results showed that both PCDFs were degraded at high rates in lake water under high sunlight intensities, but degradation slowed down under midsummer sunlight conditions. Direct aqueous photolysis of PCDFs resulted in the formation of polar and nonpolar photoproducts.

Thermodynamic study on the reduction of the polychlorinated dibenzo-p-dioxins and dibenzofurans in incinerator exhausts
Article Abstract:
Thermodynamic research shows that the use of CaO, Na2O-SiO2, or 2Na2O-SiO2 will promote the dechlorination of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans in incinerator exhausts. Butane or butene will also foster the reaction. The decomposition will not take place at temperatures below 1100 K. The methods for reduction of PCDDs and PCDFs in the waste gases from municipal incinerators is discussed.

Patterns and sources of polychlorinated dibenzo-p-dioxins and dibenzofurans in sediments from the Venice Lagoon, Italy
Article Abstract:
Italy's Venice Lagoon is moderately contaminated with dibenzofurans and polychlorinated dibenzo-p-dioxins, which arrive from various pollutant sources. Such sources include diesel and gasoline engine emissions, and chemical manufacturing. The level of contamination of Venice Lagoon was found to be significantly higher than the levels of contamination in the Adriatic Sea, with which the lagoon is part of.
