摘要：The Geographic Information System (GIS) use as an epidemiological tool (ecologic studies) in Morocco is still not well known, particularly in the field of environmental health related to chemical pollutants. This work gives an idea about the GIS role, and about the encountered hindrances that may still prevent its use in this field. This is described via a case study of the relationship between nitrate in drinking well-water and spontaneous miscarriage in women living in two exposed areas in Hssaine. Salé. For comparative purposes, a reference group using municipal water and living in an adjacent area was also considered. The ecologic study showed that despite of the high nitrate levels in drinking water in the exposed areas (between 31,23 and 224,56 mg/L of NO3-in Douar Dourafaa; between 24,88 et 246,90 mg/L of NO3-in Douar Riah), the prevalence of abortion in the exposed areas (16.7℅ in Douar Dourafa and 19.6℅ in Douar Riah) was not statistically different from that in the reference area (25℅): Nitrate in drinking water was not associated to abortion in the exposed area. There is a need of further collaboration via new evidence-based tools and approaches (biomonitoring and environmental public health tracking) to collect and analyze geographically referenced data related to environmental hazards, to exposure, and to environment related health outcomes at local and regional level, and integrate them to each other
