Ecotoxicological effects of pesticides in stream sediments

Ecotoxicological effects of pesticides in stream sediments

Pesticides in sediments cause adverse effects on benthic organisms. This was shown by a monitoring study conducted by the Ecotox Centre and Eawag on five streams in agricultural areas. Crustaceans were particularly affected. Concentrations of several insecticides, including chlorpyrifos and the pyrethroid cypermethrin, exceeded effect thresholds, indicating impaired sediment quality.

How do plant production products affect Swiss fish?

How do plant production products affect Swiss fish?

Pesticides detected in Swiss streams pose a risk to the fish living there. Harmful effects on the fish, particularly through sublethal and indirect effects, are possible in the measured concentrations.

Homing in on pyrethroids

Homing in on pyrethroids

The measurement of trace concentrations of pyrethroid and organophosphate insecticides – now possible thanks to a newly developed analytical method – shows that these compounds can pose a greater threat to aquatic organisms than all other pesticides.

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.
