Further development of simple test systems for the evaluation of potential PBT substances: How to bridge the gap between screening tests and complex studies?

The first aim of the project was to assess whether the existing OECD test guidelines for ready biodegradability of chemicals (OECD test guidelines 301 A–D and 310) can be harmonized. The gained insights were discussed at an international expert workshop in April 2019. Laboratory experiments were performed for five test substances to verify the impact […]

New publication on potential synergistic interaction between fungicides in toxicity tests with Raphidocelis subcapitata

Products used for plant protection or as biocides often contain more than one active substance together with numerous formulation additives. The environmental risk assessment for such commercial mixtures applies as default the concept of concentration addition. There is remaining regulatory concern, however, that underestimation of risks can occur if components in the mixture interact synergistically, […]

New publication: Prospective environmental risk assessment of mixtures in wastewater treatment plant effluents

The aquatic environment is continually exposed to a complex mixture of chemicals, with effluents of wastewater treatment plants (WWTPs) as one key source. The aim of the present study was to investigate whether environmental risk assessments addressing individual substances are sufficiently protective for such mixtures. Based on a literature review of chemicals reported to occur […]

Use of prospective and retrospective risk assessment methods for chemical mixtures in wastewater discharges

New publication: Use of prospective and retrospective risk assessment methods for chemical mixtures in wastewater discharges

The SETAC Pellston Workshop ‘Simplifying environmental mixtures – an aquatic exposure-based approach via exposure scenarios’ addressed the need to improve mixture assessments by considering different exposure scenarios related to land use. Recently, a series of papers from this workshop was published in Environmental Toxicology and Chemistry, including the work ‘Use of prospective and retrospective risk assessment methods that simplify chemical mixtures associated with treated domestic wastewater discharges’, to which Anja Coors contributed.

Environmental risk assessment of biocidal products: identification of relevant components

New publication: Environmental risk assessment of biocidal products – identification of relevant components…

The recently published work ‘Environmental risk assessment of biocidal products: identification of relevant components and reliability of a component-based mixture assessment’ contributes to the currently ongoing debate on how to perform a mixture assessment in the environmental risk assessment within the authorisation process of biocidal products. Biocidal products are mixtures of one or more active […]

Further news on the Euro-Mediterranean Conference on Environmental Integration

About 500 scientists representing more than 20 countries participated in the 1st Euro-Mediterranean Conference on Environmental Integration (EMCEI) that took place in Sousse (Tunisia) from 22 to 25 November 2017. ECT co-organised this conference, actively contributing via a keynote speech on environmental risk assessment of pesticides in soil, and by chairing two sessions on environmental […]
