SYNOPSIS

These results highlight a relationship between environmental and residential exposure to glyphosate and high prevalence of asthma, while experimental studies support the biological plausibility of this association.

SUMMARY

Background: There is strong evidence of the link between asthma and occupational exposure to pesticides and glyphosate in agricultural workers, but it is limited on environmental or residential exposure to these chemicals. Methods: We analyze asthma prevalence in an agricultural town with high use of pesticides, mainly glyphosate with an ecological study conducted in Monte Maíz, Argentina, composed of a chemical and environmental analysis to determine the burden of exposure to glyphosate and pesticides in general, and a cross-sectional asthma study that uses the methodological criteria of the International Study of Asthma and Allergies in Childhood (ISAAC); the prevalence’s found in Monte Maíz are compared with the results of ISAAC in Argentine cities with low exposure to pesticides. Results: In Monte Maíz high and preponderant levels of glyphosate were found in the soil and in corn husk and soybean powder. The environmental exposure burden to pesticides was 121 kilos, for glyphosate 81 kilos per person per year, while this burden in the entire country is 7.9 and 6 kilos respectively. The found asthma prevalences were several times higher than those of reference in all ages, the risk of asthma in children of 13 and 14 years old, with respect to those of three large Argentine cities is: OR of 4.64 (CI: 3, 26 – 6.60). Conclusion: These results highlight a relationship between environmental and residential exposure to glyphosate and high prevalence of asthma, while experimental studies support the biological plausibility of this association.

Summary

A study assessing the effects of Roundup, glyphosate and a glyphosate metabolite found that all three damaged DNA in human blood cells, with Roundup having the strongest effects, even at very low concentrations.
