The WHO/UNEP Pilot Project on Assessment of Human Exposure to Pollutants through Biological Monitoring

The objectives, development and current status of the WHO/UNEP Pilot Project on Assessment of Human Exposure to Pollutants through Biological Monitoring are described. The project is being carried out within the framework of UNEP's Global Environmental Monitoring System (GEMS) and is supported by funds from UNEP. The long-term objective is to develop and strengthen national, regional and global biological monitoring programmes that will make it possible to accurately assess human exposure to selected toxic pollutants by measuring their concentrations in human tissues and body fluids. In this pilot project the levels of lead and cadmium in venous blood, cadmium in kidney cortex and certain organochlorine compounds in breast milk are being determined in selected population groups in 10–12 countries in different parts of the world. Each participating laboratory has been required to achieve satisfactory results in the quality assurance phase of the project before starting to analyse the human samples and quality assurance has been continued during the monitoring phase. The project started in 1978 and is scheduled for completion by July 1982.
