| Short description: |
This project investigates the relationship between soil lead concentrations and the amount of lead that adheres to the hands of children and via this dermal contact can be potentially ingested. Secondly, the effect of intervention in accordance with recommendations from the Danish EPA is assessed with respect to reduction in exposure.

| Long description: |
Human risk assessment is usually based on the oral intake of soil among young children (2-5 years) after exposure to soil on hands or toys. This exposure route is especially relevant for heavy metals as well as more persistent organic pollutants. A method to allow analysis of soil lead on hands of children was developed and investigations were carried out at three day care centres. One site was uncontaminated, whereas the other two had lead levels in the guidance interval (40 - 400 mg/kg). There was a clear, but indirect correlation between soil lead and lead levels on children’s hands. After the initial investigation, remedial measures were implemented in two day-care centres and exposure to lead was evaluated two months after implementation. No significant reduction in indoor lead dust levels was noted after intervention, but significantly reduced median exposure, was observed among children. In one of the day-care centres, the exposure after intervention was comparable to the uncontaminated day-care centre. Generally a large range in lead levels was observed among children from the same day-care centre, probably reflecting different play patterns. No gender-related differences were observed regarding lead on hands. Results indicated that exposure is expected to be higher under wet soil conditions.
