Symptoms of acute diazinon exposure develop in minutes to hours following exposure, depending of the exposure pathway.

Is house dust the missing exposure pathway for PBDEs?

Potential exposure pathways (e.g., terrestrial surface radiation, inhalation, ingestion, dermal)

"We are somewhat uncertain at this point about potential exposure pathways," Dr. Ulirsch said.

Several exposure pathways are possible for both plants and animals in terrestrial systems.

The database currently has over 2000 entries indexed by particle type, exposure pathway and other criteria.

Currently, in the United States, there are 126 Superfund sites (with a completed exposure pathway) contaminated with dioxins.

"This gets rid of the exposure pathway," Mr. Fiteni said.

The Commission continues to hold that view on the basis of the evidence that, in the marine environment, the only exposure pathway is the slow dissolution of uranium.
