Production and dechlorination of 2,3,7,8-tetrachlorodibenzo-p-dioxin in historically-contaminated estuarine sediments
Article Abstract:
Decontamination of estuaries and water ways of dioxin might be achieved using bioremediation. Researchers tested sediment taken from the Lower Passaic River in New York State near an abandoned chemical factory that had produced sodium 2,4,5-trichlorophenate. Researchers found varying levels of contaminates. They theorized that reductive dechlorination of the sample in an anaerobic environment is one means for dechlorination. By removing a peri (1,4,6,9-chlorine), dechlorination increased. This leads the authors to believe that natural systems can be stimulated to decompose dioxin.

Detailed Studies of the Factors Controlling Atmospheric PCDD/F Concentrations
Article Abstract:
Researchers examined air samples taken in Lancaster, England between September and December 1997 to analyze the amounts of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans in the atmosphere, and the directions from where the pollutants traveled. Tables and figures accompany the article.

Factors Influencing the Distribution of Lindane and Other Hexachlorocyclohexanes in the Environment
Article Abstract:
Researchers examined speculation that one isomer of Hexachlorocyclohexanes, an organochlorine insecticide, could be transformed in the environment into a longer-lived, and possibly more toxic chemical.
