Nanotechnology and human health: Scientific evidence and risk governance - Report of the WHO expert meeting 10–11 December 2012

WHO ; World Health Organization

Nanotechnology, the science and application of objects smaller that 100 nanometres, is evolving rapidly in many fields.; Besides the countless beneficial applications, including in health and medicine, concerns exist on adverse health; consequences of unintended human exposure to nanomaterials.; In the 2010 Parma Declaration on Environment and Health, ministers of health and of environment of the 53 Member States; of the WHO Regional Office for Europe listed the health implications of nanotechnology and nanoparticles among the key; environment and health challenges.; The WHO Regional Office for Europe undertook a critical assessment of the current state of knowledge and the key; evidence on the possible health implications of nanomaterials, with a view to identify options for risk assessment and policy; formulation, and convened an expert meeting to address the issue.; Current evidence is not conclusive. As complexity and uncertainty are large, risk assessment is challenging, and formulation; of evidence-based policies and regulations elusive.; Innovative models and frameworks for risk assessment and risk governance are being developed and applied to organize; the available evidence on biological and health effects of nanomaterials in ways to inform policy.
