See what regulators from around the world say about atrazine's safety and effectiveness.
“Joint FAO/WHO Meeting on Pesticide Residues concluded that atrazine is not likely to pose a carcinogenic risk to humans.” -Background document for development of WHO drinking water guidelines, World Health Organization
“Taking into consideration the recent epidemiology publications since the 2011 Scientific Advisory Panel, including the strongest evidence derived from [the] Agricultural Health Study, as well as the Weight of Evidence, the Agency concludes that, while uncertainties remain, the totality of the available evidence does not support an association between atrazine exposure and human cancer.” -Draft Atrazine Human Health Risk Assessment, EPA
“As atrazine has been classified as “not likely to be carcinogenic to humans,” cancer risk is not a concern…” -Draft Atrazine Human Health Risk Assessment, EPA
“A systematic review was conducted on published epidemiology studies in the public literature that focused on carcinogenic and non-carcinogenic effects relative to atrazine exposure… Overall, there is little substantive evidence to suggest a clear associative or causal relationship between exposure to atrazine and the carcinogenic and non-carcinogenic health outcomes investigated in the studies reported here.” -Atrazine: Tier II Epidemiology Report, EPA
“The Panel has concluded that there is sufficient information available to reach the conclusion that the issue of differential sensitivity has been adequately studied. This relatively extensive database, spanning all life stages from conception to adulthood indicates no unique susceptibility to atrazine in the developing organism.” -Meeting minutes, FIFRA Scientific Advisory Panel
“Model-estimated atrazine concentrations, as well as measured concentrations for community water systems are well below the drinking water level of concern. The vast majority of atrazine samples from the AMP [Atrazine Monitoring Program] show concentrations below 1 ppb…” -Atrazine Interim Registration Review Decision, EPA
“Residues of atrazine and its chlorinated transformation products in drinking water are not considered to be of concern to human health.” -Proposed Decision for Consultation, Canadian Pest Management Regulatory Agency
“Based on this scientific approach, the PMRA has concluded that there are no acute or chronic risks of concern from atrazine in groundwater at the maximum detected concentration in Canadian groundwater.” -Special Review Decision: Atrazine, Canadian Pest Management Regulatory Agency
“The Pest Management Regulatory Agency (PMRA) follows a risk-based scientific approach in determining the risk to human health from pesticides in drinking water. This approach takes into consideration both the estimated level in drinking water sources and the toxicity of the pesticide. Based on the drinking water risk assessment of atrazine and its chlorinated transformation products, the PMRA concludes that there are no acute or chronic risks of concern from groundwater under the current conditions of use.” -Proposed Decision for Consultation, Canadian Pest Management Regulatory Agency
