The principal purpose of the report is to present estimates of truck shipments of acetone, one of the 147 large-volume chemicals (non-fuel) that account for at least 80% of U.S. truck shipments of hazardous chemicals. Because there is so little direct evidence on the secific routes over which acetone is shipped, and in what quantities, this information is estimated by the use of models. Two widely-used models of interregional commodity flows have been used: a gravity model and a linear programming model, each generating its own set of results. Both sets of results show quantities of acetone flowing through individual states, and both are displayed graphically on flow maps.
