Lead Risk Assessment for Contaminated Land: The Key Issues
2011 Summer Workshops
Lead is a widespread contaminant which is a key contaminant of concern at many sites. Currently there is much uncertainty in the approach to assessing the risks to human health from lead. This workshop aims were to:
- identify the key uncertainties in the assessment of risks to human health from lead in soil
- find where there is (and is not) consensus of opinion on how these uncertainties are best managed in the risk-based decision-making process; and
- provide recommendations for possible further research to address any outstanding issues.
This workshop follows the same format as last year’s highly successful workshop with thought-provoking presentations in the morning followed by an afternoon of break-out session discussion groups.
