Waste ecocompatibility in storage and reuse scenarios: global methodology and detailed presentation of the impact study on the recipient environments.

In 1995, the ADEME launched a research program called "Waste Ecocompatibility" in order to define a reliable methodology for measuring the impact of waste in storage or reuse scenarios. The French concept of "Ecocompatibility" is defined as the situation where the pollutant flux from waste disposed of or used in specified conditions is compatible with the environmental acceptance of the receiving environments. The chief feature of this definition is to integrate the evaluation of the three following terms: pollutants emission from the waste, transport of the pollutants from the waste to the receptor cells and the environmental acceptance of the receiving environments.

Sensitivity of epigean and hypogean freshwater macroinvertebrates to complex mixtures. Part I: Laboratory experiments.

The impact of waste storage on aquatic systems is a regulatory requirement in Europe, but it is nowadays only considered to a limited extent. The complexity of mixtures, which contain many inorganic and organic compounds, requires the use of combining chemical measurements with ecotoxicological observations. This research employed an integrated laboratory and outdoor mesocosms approach to assess the effects of mixtures on freshwater macroinvertebrates.

Toxicity and bioaccumulation of arsenic and chromium in epigean and hypogean freshwater macroinvertebrates.

Lethal toxicity levels of two inorganic water pollutants, chromium (Cr6+) and arsenic (As3+), were determined toward six freshwater macroinvertebrate species collected from a single field site. Crustaceans were represented by two amphipod species, an epigean one (Gammarus fossarum) and a hypogean one (Niphargus rhenorhodanensis), and by an isopod species (Asellus aquaticus). There were two insect larvae, Heptagenia sulphurea (Ephemeroptera) and Hydropsiche pellucidula (Trichoptera) and a snail, Physa fontinalis.
