Benz[a]anthracene in earthworms from the Saartal and the city of Leipzig

Differences in contamination between two regions with high anthropogenic impact

Benz[a]anthracene is mainly produced by combustion of organic material. It is environmentally persistent and accumulates in organisms.
Benz[a]anthracene levels differ strongly in earthworms from two sites with high anthropogenic impact. In the Saartal contamination of earthworms is up to 19-times higher than in Leipzig. Concentration trends over time are not apparent at either site. These data point towards strong differences in benz[a]anthracene soil contamination.
