Century Perspective of Heavy Metal Use in Urban Areas. : A Case Study in Stockholm

• The inflow and stock (amount in use) of heavy metals (cadmium (Cd), chromium (Cr),copper (Cu), lead (Pb), mercury (Hg), nickel (Ni) and zinc (Zn)) in goods in 1995 have been quantifiedin the anthroposphere of Stockholm, Sweden. Statistics on national, regional and local levelwere used. Contacts were established with representatives from production and construction in theindustrial sector and with authorities. The results show that the stock of Cd is 0,2 kg per capita. Forthe other heavy metals the corresponding result per capita is: Cr 8, Cu 170, Hg 0,01, Ni 4, Pb 73and Zn 40 kg. The inflow varies between 2–8% of the stock indicating the importance of the stock.The lowest levels are for Cu and Pb. Heavy metal levels in solid waste are high, between 15–45%of the amount in the inflow (Hg excluded), the lowest values were for Cu and Pb. Thus, recycling isincomplete. Long life expectancy goods form the majority of the stock but there is a tendency thatshort life expectancy goods increase their importance in the inflow. Concealed goods are also morefrequent in inflow than in the stock.
