Insecticide species sensitivity distributions: importance of test species selection and relevance to aquatic ecosystems.
Single-species acute toxicity data and (micro)mesocosm data were collated for 16 insecticides. These data were used to investigate the importance of test-species selection in constructing speciesExpand

Threshold Levels for Effects of Insecticides in Freshwater Ecosystems: A Review
A literature review of freshwater (model) ecosystem studies with neurotoxic insecticides was performed to assess ecological threshold levels, to compare these levels with the first tier approachExpand

Comparison of Tropical and Temperate Freshwater Animal Species' Acute Sensitivities to Chemicals: Implications for Deriving Safe Extrapolation Factors
Abstract Toxicity data for tropical species are often lacking for ecological risk assessment. Consequently, tropical and subtropical countries use water quality criteria (WQC) derived from temperateExpand

Fungicide risk assessment for aquatic ecosystems: importance of interspecific variation, toxic mode of action, and exposure regime.
The risk assessment of fungicides in Europe uses information from ecotoxicity studies performed on vertebrates, invertebrates, and primary producers, but not nontarget fungi. But which toxicity dataExpand

Effects of preservation on dry- and ash-free dry weight biomass of some common aquatic macro-invertebrates
The effect of preservation methods on dry weight (DW) and ash-free dry weight (AFDW) of Radix peregra (Gastropoda), Asellus aquaticus (Isopoda), Erpobdella octoculata (Hirudinea) and GlyptotendipesExpand

Effects of chlorpyrifos in freshwater model ecosystems: the influence of experimental conditions on ecotoxicological thresholds.
Three experiments were conducted to determine the impact of the insecticide chlorpyrifos (single applications of 0.01 to 10 microg AI litre(-1)) in plankton-dominated nutrient-rich microcosms. TheExpand

Effects of chronic low concentrations of pesticides chlorpyrifos and atrazine in indoor freshwater micro-cosms
Abstract Effects of chronic low concentrations of chlorpyrifos (0.1 μg.L−1) and atrazine (5 μg.L-−1) were studied in indoor freshwater microcosms. Test concentrations were based on a factor of 0.1Expand

The minimum detectable difference (MDD) and the interpretation of treatment-related effects of pesticides in experimental ecosystems
In the European registration procedure for pesticides, microcosm and mesocosm studies are the highest aquatic experimental tier to assess their environmental effects. Evaluations ofExpand

Aquatic Risks of Pesticides, Ecological Protection Goals, and Common Aims in European Union Legislation
Abstract This discussion paper presents a framework for spatiotemporal differentiation in ecological protection goals to assess the risks of pesticides in surface waters. It also provides a proposalExpand

The use of terrestrial and aquatic microcosms and mesocosms for the ecological risk assessment of veterinary medicinal products.
In this paper, we investigate the applicability of experimental model ecosystems (microcosms and mesocosms) for the ecological risk assessment of veterinary medicinal products (VMPs). VMPs are usedExpand
