A new study from Argentina, which used the methodological criteria of the International Study of Asthma and Allergies in Childhood (ISAAC), has identified a relationship between environmental and residential exposure to glyphosate and the high prevalence of asthma in the small city of Monte Maíz in Argentina.

This study has a very unusual story, as it was started at the request of a group of citizens, led by the Mayor of Monte Maíz, due to their concerns about previously rare diseases becoming more prevalent in the city. The citizen group requested an evaluation of the health status of their local population from a research team at the Division of Medical Sciences of the National University of Córdoba (UNC), in which the researchers evaluated the health of the entire population through a door to door survey covering every household, alongside detailed environmental analysis.

The study was carried out in order to determine if there had been an increase in the prevalence of cancers, reproductive, endocrine and immunological problems, and asthma linked to a greater exposure to pesticides. The objective was to analyze the environmental exposure to pesticides as a risk factor for the above-mentioned diseases and to correlate environmental factors in order to develop a causality hypothesis.
