Abstract
In the ancient Pb-Zn mining area of Plombières, spiders were monthly sampled with pitfall traps during one year. Based on the total of soil concentrations of cadmium, copper, mead and zinc, it was expected that zinc would probably have the strongest adverse effect. neither total zinc concentration, nor with water soluble and calciumchloride extracable concentrations affected total spider activity and species richness significantly. In fact, despitethe high metal concentrations in the soil, it was not immediately clear that spider composition was affected in the study area. The apparent lack of effects at the high observed zinc concentrations was attributed to the relatively low bioavailability of zinc to the spiders at the study sites, which was also reflected by the low detected water soluble zinc concentrations. However, more detailed analysis revealed that the number web-building spiders decreased, while number of hunting spiders increased with increased calcium chloride extractable zinc concentrations.
