Global Network Grows to Assess Chemical Risks and Improve Health

A global collaborative approach to human health risk assessment

The production, use, and disposal of chemicals are increasing worldwide and are governed by a wide range of regulations and laws in different countries. Chemicals provide important benefits to society but many also pose health risks to humans and the environment. The need to understand and manage the risks associated with chemical exposures poses a big challenge. The challenge is greater especially in countries with limited scientific knowledge and resources.

Global Burden of Disease Update Reveals Major Risk Factors for Death and Disability

Modifiable risk factors explain more than half of global deaths and more than one-third of global disability-adjusted life years (DALYs), according to a recent update to the Global Burden of Disease Study (called GBD 2013, as this is the most recent year for which the data were analyzed). A study published recently in the Lancet provides new insights into the attribution of the burden of disease to behavioral, environmental and occupational, and metabolic risk factors.

Voices from the Field: Community Based Pesticide Exposure Research in Ecuador’s Flower Industry

Field in Ecuador

In Ecuador, cut-flowers are the third most valuable export, behind oil and bananas. The heavy use of pesticides in the industry may expose flower workers, the majority of whom are young women of reproductive age, to harmful chemicals. These workers are also exposed to stressful working conditions and long hours, and often carry the additional burden of domestic responsibilities. Alexis. J. Handal, Ph.D., of the University of New Mexico, wants to understand how the cut-flower industry may affect maternal health and neurodevelopment in infants and young children.

NIEHS Climate Change and Environmental Exposures Challenge
Climate change is likely to alter the risks posed by environmental exposures in ways that are just beginning to be explored. NIEHS invites you to help decision makers around the country understand and address climate change’s effects on environmental health risks by joining the Climate Change and Environmental Exposures Challenge (#climatechallengeNIEHS). By creating data visualization tools and maps that connect current science on climate change to the exposure pathways for environmental hazards, innovators can help identify areas and people at greatest risk and help to prioritize protective actions.

Funding Opportunities


  • Climate Change Country Profiles
    WHO recently released the Climate and Health Country Profiles of 15 countries around the globe. These profiles provide relevant and reliable country-specific information about the current and future impacts of climate change on human health, the opportunities for health co-benefits from climate mitigation actions, and current policy responses at country level.
  • Heatwaves and Health: Guidance on Warning-System Development
    The World Meteorological Organization and WHO outline the issues surrounding the general heat–health problem and present how an understanding of the biometeorology, epidemiology, public health, and risk-communication aspects of heat as a hazard can be used to inform the development of a heat adaptation plan. The Guidance has been produced to have global applicability.
  • Operational Framework for Building Climate Resilient Health Systems
    This WHO operational framework provides guidance for health systems and public health programming to increase their capacity for protecting health in an unstable and changing climate.
  • Improving Nutrition Outcomes with Better Water, Sanitation and Hygiene: Practical Solutions for Policy and Programmes
    This document, jointly prepared by WHO, UNICEF, and USAID, summarizes the current evidence on the benefits of safe drinking-water, sanitation, and hygiene (WASH) for improving nutrition outcomes and describes how WASH interventions can be integrated into national nutrition policies and programs. It is also a valuable tool to help countries implement the policy options on WASH recommended in the Framework for Action adopted by the 2nd International Conference on Nutrition in 2014.
