This project aimed to create an integrated software package to assess the transport of chemical pollutants in the environment. It provided European and national regulatory agencies and industry with a state-of-the-art tool for better prediction of concentrations of chemicals - […]
Skin cancers are very common in humans - with around one million cases/year in the US - and their development can be affected by stimulators of growth such as certain chemicals. Although initiation is clearly extremely important, clonal expansion (promotion) […]
The software system will consist of functional modules allowing evaluation of the data stored in a database and various user interface modules. Compounds database will contain chemical structure, identifiers (including CAS numbers), imported descriptors and experimental data. The functional modules […]
This Workshop was designed to bring together relevant expertise and to reach a consensus recommendation on a standardised protocol for in vitro determination of permeability coefficients. The proposed protocol is intended, in the first instance, for testing aqueous soluble chemicals […]
The environmental risk posed by any new chemical produced or used in substantial quantities in the EU had to be assessed. This process involved estimating the concentration of the substance that could be present in water without harming aquatic life. […]
Occupational asthma is the commonest occupational lung disease, accounting for 5% of all cases of asthma, and incidence is rising. Sufferers lose on average half their total take-home income (including compensation) for four years after diagnosis. Whilst the clinical and […]
Existing data on ecotoxicity of chemicals for water, sediment and soil varies widely in quality, quantity, validity, and how representative it is. This is due to environmental concerns having initially focused water, with soil and sediment taken into account only […]
The toxicological data profiles of many of the more than 100,000 substances included in the EINECS are incomplete. Scientific tools are needed to minimize test requirements and to prioritise research needs. Here consideration of Structure Activity Relationships (SAR) could be […]
The persistence of a chemical in the environment - how resistant it is to being broken down in nature - is hard to predict. Its tendency to build up in living organisms - to bioconcentrate or bioaccumulate - is similarly […]
Many adverse health effects of chemical exposure occur after repeated contact over long periods. In assessing the risks of such chronic effects in the workplace, "reasonable worst case" estimates of exposure during a shift or working day are often used. […]
