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 quantified in the anthroposphere of Stockholm, Sweden. Statistics on national, regional and local level were used. Contacts were established with representatives from production and construction in the industrial sector and with authorities. The results show that the stock of Cd is 0,2 kg per capita. For the other heavy metals the corresponding result per capita is: Cr 8, Cu 170, Hg 0,01, Ni 4, Pb 73 and 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 is incomplete. Long life expectancy goods form the majority of the stock but there is a tendency that short life expectancy goods increase their importance in the inflow. Concealed goods are also more frequent in inflow than in the stock. [ABSTRACT FROM AUTHOR]
