title: Hazard assessment of chemical contaminants in soil.
abstract: Disposal practices, accidental spills, leakages and local aerial deposition occurring in the past have led to local soil pollution in many cases. Especially in situations where people live on or nearby such locations this has created concern about possible adverse effects on human health. A stepped approach to the hazard assessment of polluted soil, as developed by a Task Force from the European Chemical Industry Ecology and Toxicology Centre (ECETOC), is described. In an early phase in the assessment process the potential exposure of humans is estimated. The Human Exposure to Soil Pollutants (HESP) model can be applied for this purpose. The model calculates the total exposure of adults and children resulting from pollutants present in soil, via 10 different exposure routes. The estimated exposure can be used to indicate the potential significant exposure routes and to carry out a preliminary hazard assessment. The model is also able to predict pollutant concentrations in soil which do not exceed accepted maximum exposure levels for humans in both standardised and site specific situations. The stepped approach is cost-effective and provides an objective basis for decisions and priority setting.
