A range of documents provide information about the health impacts of lead, sources of lead exposure and methods for evaluating exposure. Key WHO risk assessment documents concerning lead are also provided. These resources can be used by governments and international and national organizations as the basis for taking preventive actions against adverse health and environmental impacts.

As the basis for managing the risks of chemical exposure, the Chemical Risk Assessment (CRA) process can impact a substantial part of the economy, the health of hundreds of millions of people, and the condition of the environment. However, the number of properly assessed chemicals falls short of societal needs due to a lack of experts for evaluation, interference of third party interests, and the sheer volume of potentially relevant information on the chemicals from disparate sources.In order to explore

ContextTo address the recognized deficiencies mentioned above, it’s essential to have a ‘chemicals ecosystem (SAICM ecosystem)’ in which relevant information can be shared transparently and easy to obtain. In this ‘chemicals ecosystem’, a holistic chemicals-information-sharing hub, serving as ‘database’ and ‘scanner’ on chemicals management, should be developed to provide connection on knowledge and information from a wide variety of sources and allow stakeholders to identify their gaps on the way towards the sound management of chemicals and waste.
