Study identifies sources of airborne dioxin in Great Lakes

Article Abstract:

A study of atmospheric depositions of dioxins to the Great Lakes conducted by the Center for the Biology of Natural Systems at Queens College, NY, revealed that airborne sources greater contributes more in polluting the lake than waterborne sources. Data gathered from combining emissions data from waste incinerators with data from an air transport model showed that 100 sources from the total 1329 sources contributed in increasing waterborne dioxins in the Great Lakes. The study also showed that states as far as Florida, Louisiana, Utah and Texas are contributors of dioxins to Lake Erie via airborne sources.

Study finds no correlation between chlorine incineration and dioxin formation

Article Abstract:

Results of a study conduced by the American Society of Mechanical Engineers refuted claims of a correlation between chlorine incineration and dioxin formation. The conclusion counters the claim by environmental groups that heavily chlorinated materials have to be removed to reduce dioxin emissions. However, critics countered that the study controlled for only the chlorine variable and looked only for dioxin leaving the stack.

Dioxin risk reassessment stalls: EPA to create new review panel

Article Abstract:

The EPA has extended the submission of the EPA draft of the reassessment of dioxin to Sep. 1995. The agency requested the added time to further analyze the toxic effects of herbicides on human health particularly on the functions of the endocrine, reproductive and immune systems. It will organize new groups of scientists to develop a more comprehensive report.
