ABSTRACT: Argentina annually utilizes 240,000 tones of glyphosate in industrial agriculture and a change in the profile of morbidity is perceived for physicians of agricultural areas; now reproductive disorders seem to prevail. The objective of this study is to determine concurrence of glyphosate exposure and reproductive disorders in a typical argentine agricultural town (Monte Maíz). An ecological study was developed with an environmental analysis of pollution sources including measurements of glyphosate and other pesticides and a cross-sectional study of spontaneous abortions and congenital abnormalities prevalence. Glyphosate was detected in soil and grain dust and was found to be at an even higher concentration in the village soil than in the rural area; 650 tonnes of glyphosate are used annually in the region and manipulated inner town contaminating the soil and dust in suspension of the town creating an burden of environmental exposure to glyphosate of 79 kg per person per year. We do not find other relevant sources of pollution. The spontaneous abortion and congenital abnormalities rates are three and two times higher than the national average reported by the national health (10% vs. 3% and 3% - 4.3% vs 1.4% respectively). Our study verified high environmental exposure to glyphosate in association with increased frequencies of reproductive disorders (spontaneous abortion and congenital abnormalities) in argentine agricultural village, but is unable to make assertions cause-effect. Further studies are required with designs for such purposes.
