About BARGE

BARGE (the Bioaccessibility Research Group of Europe) is a European network bringing together international institutes and research groups to study human bioaccessibility of priority contaminants in soils such as arsenic, lead and cadmium via the gastrointestinal tract.

The correct estimation of bioaccessibility has the potential to impact on current risk assessment practice in a major way. BARGE members are currently involved in comparing and evaluating the many models and systems that have been developed over the years to measure bioaccessibility and contaminant exposure (Oomen et al. 2002). A priority objective is to provide robust and defensible data on bioaccessibility that can be used in human health risk assessment and policy making.

7th International Workshop on Chemical Bioavailability in the Terrestrial Environment, Nottingham, UK, 4th - 7th November 2013

On behalf of the International Organising Committee, the British Geological Survey (BGS) and Nottingham University invite everyone to discuss and exchange new and emerging scientific breakthroughs in chemical bioavailability at the 7th International Workshop on Chemical Bioavailability (IWCB).

UBM Validation Paper Accepted For Publication

UBM Validation Paper in Environmental Science and Technology Journal

A paper entitled "In vivo Validation of the Unified BARGE Method to assess the Bioaccessibility of Arsenic Antimony, Cadmium and Lead in soils" has been accepted for publication in the Environmental Science and Technology Journal. This paper is an important scientific milestone for the provision of robust and defensible ingestion bioaccessibility data for risk assessments for professional and academics working in contaminated land management.

Unified Bioaccessibility Method (UBM)

The BARGE Unified Bioaccessibility Method

Some time ago we undertook a joint decision to progress research in the field of in vitro bioaccessibility method development in order to harmonise the use of bioaccessibility in human health risk assessments for contaminated soils in Europe.
