ECETOC task forces are established by ECETOC's Scientific Committee in response to an identified need or objective, which typically sit within the framework of its strategy.

The work of an ECETOC task force follows a terms of reference established by the Scientific Committee. Each task force is directed by a chairman, who is responsible for assuring the completion of its objectives. And each task force is supported by a scientific officer from the ECETOC Secretariat.

Within the 5 broad science themes that underpin ECETOC's science strategy, current and recent task forces include:

Completed: Development of guidance for assessing the impact of mixtures of chemicals in the aquatic environment Completed: Low-dose interactions

Report in press: Development of interim guidance for the inclusion of non-extractable residues (NER) in the risk assessment of chemicals ERA of ionisable compounds Report in press: Understanding the relationship between extraction technique and bioavailability

Completed: Development of guidance for assessing the impact of mixtures of chemicals in the aquatic environment Exploring novel ways of using SSD to establish PNECs for industrial chemicals Guidance for classification of reproductive toxicants under GHS Original TF completed but ongoing work published in peer-reviewed journals:  Guidance on interpreting endocrine disrupting effects within the constraints of REACH and the revised 91/414 directive Report and paper in press: The application of critical body burden in risk assessment

Assessment and evaluation of risks resulting from dermal exposure to chemicals Completed: Category approaches, read-across, (Q)SAR Mode of action and identification of adverse vs. non-adverse effects PBT Criteria (Annex XIII of REACH) Poorly soluble particles / lung overload Completed: Risk assessment approaches for PBT/vPvB or POPs Targeted risk assessment

Cyanides antidotes ERA of ionisable compounds Guidance for classification of reproductive toxicants under GHS Original TF completed but ongoing work published in peer-reviewed journals:  Guidance on interpreting endocrine disrupting effects within the constraints of REACH and the revised 91/414 directive PBT Criteria (Annex XIII of REACH) Potency in carcinogenicity and reproductive toxicity classification Practical guidance for the risk assessment of genotoxic carcinogens Completed: Risk assessment approaches for PBT/vPvB or POPs Targeted risk assessment

(Some task forces appear under more than one science theme)
