Oligochaetes show influence of WWTP effluent on sediments

Oligochaetes show influence of WWTP effluent on sediments

The biological quality of two Swiss river sediments downstream of wastewater treatment plants is significantly worse than upstream. The Ecotox Centre scientists have been able to show this using oligochaetes .

Bioassays and standardisation for the assessment of surface waters

Bioassays and standardisation for the assessment of surface waters

A rough evaluation concept is available for the assessment of wastewater-polluted surface waters in Switzerland with the help of bioassays. Progress has also been made in standardising the individual work steps.

Do EQS protect against the spread of antibiotic resistance?

Do EQS protect against the spread of antibiotic resistance?

The environmental pollution with antibiotics can lead to more resistance against these substances. However, the generation of antibiotic resistance is not taken into account when deriving environmental quality criteria (EQS). For eight substances, the Ecotox Centre has investigated whether the available EQS also protect against the development of antibiotic resistance in surface waters.

High risks due to pesticide mixtures

High risks due to pesticide mixtures

The use of organic pesticides leads to high ecotoxicological risks for plants, invertebrates and vertebrates - this has been confirmed by a comprehensive study in five creeks. The results from biotests and bioindicators confirm the results from chemical analysis.
