Network of WHO Collaborating Centres for Children’s Environmental Health

The Chulabhorn Research Institute (CRI) in Bangkok, Thailand aims to provide scientific evidence supporting the idea that gestation is a period of high sensitivity to environmental chemicals, and that exposures during early development may lead to an increased risk of disease later in life. Scientists at CRI study how exposure to environmental pollutants, such as traffic-related air pollutants, electronic waste (e-waste), and arsenic, can affect children’s health. The knowledge gained from these studies will inform national policies to protect children’s health and reduce environmental health risks.

As a hub in a global network of researchers committed to advancing children’s environmental health, the CRI Centre is:

  • Promoting and assisting capacity building and awareness raising activities in environmental and occupational health, toxicology, and risk assessment.
  • Promoting and conducting collaborative environmental health research, particularly as it relates to emerging national and international problems and in vulnerable groups, such as children.
  • Establishing and maintaining linkages with relevant research institutions, particularly in the South-East Asia and Western Pacific regions.
  • Acting as a regional Centre for training in chemical safety.
