- Abstract
Scandinavia has one secondary lead smelter that recycles lead from approximately 85% of used car batteries in Scandinavia and which has been active since the 1940s. The smelter, situated in Landskrona, has undergone a comprehensive clean up program during the last decade, during which time production has doubled, while at the same time discharges of dust and lead to the atmosphere have decreased. Top and depthsoil samples were taken on a 0.5 km x 0.5 Km grid throughout the city of Landskrona, which covers an area of approximately 15 km2. Samples were analyzed by ICP-AES for a number of elements including Pb, Zn, Cu, Cd, As, Sb and Hg. Road dust samples from selected sites were collected and similarly analyzed. Blood samples were taken from 37 volunteer schoolchildren (aged 8-11) from two schools in Landskrona. House dust samples were taken from each child's home. Soil samples were taken from homes which had gardens, public and school playareas. Elevated heavy metal concentrations were found in close proximity to the secondary lead smelter, and this soil enrichment influences the whole of the town, modified to some extent by the prevailing wind. The smelter does not influence the soil lead concentration at distances greater than 3.5 km, where the soil reflects the background value for the area. Road dust samples also show decreases in lead concentrations with distance from the smelter. The average level of lead in house dust was considerably lower than that found in Birmingham, UK. Blood lead levels in the child population ranged from 1.5-5.1 mu gdl-1, with a mean of 3.05 mu g dl-1, showing adistinct decrease from those measured in 1978-82. No significant difference in blood lead concentrations with distance of the home from the smelter, nor between attenders at the two schools was revealed in the limited number of children studied.
