The team, led by the United Nations Environment Programme (UNEP) and working in close cooperation with the Lebanese authorities, will be visiting and sampling sites thought to present potential risks to human health, wildlife and the wider environment. Achim Steiner, United Nations Under-Secretary General and UNEP Executive Director, said: ?There is an urgent need to assess the environmental legacy of the recent conflict and put in place a comprehensive clean-up of polluted and health-hazardous sites?. This post conflict assessment is being undertaken in response to a request by the Lebanese government to assist in the development of a framework for guiding international reconstruction efforts, said Mr Steiner.
