The Swedish weathering rate model, PROFILE is the only existing model with this capacity. The PROFILE model is widely used and has been used successfully in sustainability assessments for forests and agriculture. The

The study involved two elements: (1) calculations of material and energy needs for constructing an eco-house in Toarp and a standard house in Oxie, southern Sweden; and (2) EF analysis of consumption patterns in households from Toarp and Oxie. A difference of only 10% was observed in the comparison of the building materials between the two houses. Building materials represent less than 5% of the annual EF in Toarp and Oxie. There was no significant difference in the EF between the two towns. The average annual EFs are 2.8 ha per person and 3.7 ha per person in Toarp and Oxie, respectively. Food consumption and energy consumption for housing (space heating and electricity use) are the largest contributors to the EF in Toarp and Oxie. These factors are almost equal in size and constitute 75% of the total EF in both Toarp and Oxie.

The aspects which are discussed are: selection of a computation model, determination of environmental-quality criteria for the metals, collection of input data, and assessment of the sources of uncertainty. The computation models described are based on the concept of equilibrium partitioning between dissolved and adsorbed phases in soil, surface water and sediment compartments in a steady-state situation. Application examples show that present loads of heavy metals in Europe may exceed critical loads, especially for lead, cadmium, copper and zinc.
