The purpose of this tool is to familiarize readers with key concepts of lead (Pb) risk assessment as the basis for developing and carrying out investigations in resource-constrained settings where children have been found to have elevated blood lead levels (BLLs). This tool is organized sequentially, proceeding from background research to design and execution and finally to interpretation and communication of results. It also includes supporting information in the form of technical annexes on sampling methods and the estimation of BLLs, and case studies in the main text to illuminate key concepts.
This tool is intended to be used as part of the Lead-Free Future Toolkit, under development by a working group led by UNICEF. The purpose of the Toolkit is to help accelerate action to end childhood lead exposure. Target audiences include staff members of ministries of health and environment, international organizations and non-governmental organizations (NGOs) with moderate to no experience in childhood lead poisoning and its sources. This tool and the rest of the Toolkit should not be taken as representing the views of the authors or the organizations with which they are affiliated, nor should it be viewed as definitive. It will be revised on a rolling basis as new information becomes available.
