[BDSP. Notice produite par INIST vFSPR0x2. Diffusion soumise à autorisation]. This paper discusses the role of small area spatial analysis of birth defects in environmcntal surveillance. Two approaches are reviewed : (I) the investigation of identified geographically localised potential environmental hazards, and (2) the detection of clustering. Examples are given where these types of investigation have been used in the follow-up of individual clusters. Finally, it is argued that environmental surveillance, incorporating the 2 groups of spatial methods, should become a part of public health practicc on both proactive and reactive basis.
