摘要：The results of an epidemiological descriptive study based on the cases reported by the Districtual Public Health Departments are presented. The incidence of methemoglobinemia rates in 0-1 years aged infants varied between 1.5 o/oo and 7.0 o/oo during 1996-2000 in eastern Romania territory. An increasing trend of cases was also found and the results outlined that the highest frequencies appeared in the infant’s early life (three months). The analyses of well water samples indicated both chemical (especially by nitrogenous substances) and bacteriological contamination, the frequencies of improper samples varying between 45.8% and 65.9 %. Thus, the high risk areas in Moldova territory were defined and scaled on risk level
