    Title
    Hazardous Concentrations for Ecosystems (HCE): calculation with CATS models
    Translated Title
    'Hazardous Concentrations for Ecosystems' (HCE): berekening met CATS modellen
    Publiekssamenvatting
    Dosis-respons functies, uit laboratorium toxiciteitstoetsen, werden gebruikt om het effect van stoffen op voedselwebben te voorspellen. Directe effecten van Chloorpyrifos (CPF), zoals vastgesteld in microcosmos experimenten, konden goed worden voorspeld op basis van toxiciteitstoetsen in het laboratorium. De aard van de indirecte effecten van CPF op functionele groepen kon ook voorspeld worden. Indirecte en/of directe toxische effecten leiden tot biomassaveranderingen in het voedselweb. Voorgesteld wordt om 5% biomassa-afwijking t.o.v. de controle als grens te laten fungeren voor de Hazardous Concentration for Ecosystems (HCE). HCE's zijn berekend voor cadmium, CPF, DTDMAC en TBT, en zijn altijd hoger dan huidige Grenswaarden. De betekenis van de HCE wordt besproken.<br>
    Dose-response functions were fitted on data from laboratory toxicity tests and were used to predict the response of functional groups in food webs. Direct effects of Chlorpyrifos (CPF), as observed in microcosm experiments, could be modelled adequately by incorporating dose-response functions in a CATS model. Indirect effects of CPF on functional groups, resulting from direct toxicity, could be predicted with the model too. The ecosystem response to toxicants was used to propose a quality standard called the Hazardous Concentration for Ecosystems (HCE). The HCE is based on both direct and indirect effects and is reached at a proposed 5% deviation of control biomass. The calculated HCEs for cadmium, Chlorpyrifos and DTDMAC are higher, but within two orders of magnitude of (proposed) Limit Values. The discrepancies are discussed.<br>

    By default, clicking on the export buttons will result in a download of the allowed maximum amount of items.

    To select a subset of the search results, click "Selective Export" button and make a selection of the items you want to export. The amount of items that can be exported at once is similarly restricted as the full export.

    After making a selection, click one of the export format buttons. The amount of items that will be exported is indicated in the bubble next to export format.
