| Zusammenfassung |
| Determination of the contaminant content is not enough to evaluate the toxic effects or to
characterise contaminated sites, because such a measure does not reflect the ecotoxicological
danger in the environment and does not provide information on the effects of the chemical
compounds. To estimate the risk of contaminants, chemical methods need to be
complemented with biological methods. Therefore, ecotoxicological testing may be a useful
approach for assessing the toxicity as a complement to chemical analysis. The aim of this
study was to develop a battery of bioassays for the ecotoxicological screening of areas
polluted by mining activities. Particularly, the toxicity of water samples, sediments and their
pore-water extracts was evaluated by using three assays: bacteria, plants and ostracods.
Moreover, the possible relationship between observed toxicity and results of chemical
analysis was studied.
The studied area, Sierra Minera, is close to the mining region of La Uni |
