Abstract
A “bottom-up” study was conducted for in-use stocks of iron in the State of Connecticut for the base year of 2000. The study covers 145 product types in the four major categories of transportation, buildings, equipment, and infrastructure. The method of calculation, as well as the allocation of iron in different use categories is discussed. The total result of 9,300 kg of iron per capita is slightly higher than that from a previous study for the city of New Haven, but below the results of national top-down analyses. Possible reasons for these discrepancies are considered. A sensitivity analysis and an error rating were applied to the calculations to examine uncertainties
