Lead, Cadmium and Mercury Flow Analysis – Decision Support for Austrian Environmental Policy

摘要: This paper discusses the support for environmental policy decisions that can be provided by substance flow analysis (SFA). Flows and stocks of lead (Pb), cadmium (Cd) mercury (Hg) are investigated through Austrian economy environment. Two advantages SFA emphasized: first, because is based on law conservation mass, input output flows processes have to balanced. balancing principle allows identifying data gaps contradicting information supplied different sources, helps calculate missing data. Second most important making, gives "whole picture full transparency". It instrumental in showing combined effect measures such as integrated product policy, consumer protection, emission control, waste management a country its also identify hot spots which additional required reduce pressure or make use secondary anthropogenic stocks. results must carefully interpreted order distinguish between beneficial harmful stocks, e. g. when materials recycled contain large amounts hazardous heavy metals. For comprehensive base design future quantitative needs amended qualitative information, assessment tools.
