Alex Avery, Director of Research and Education
'For the last ten years I've been watching closely the research and activism of Dr. Tyrone Hayes from the University of California Berkley. And for ten years Dr. Hayes has tried to claim that atrazine is an eminent threat to amphibian populations because it feminizes frogs at some, but not all, concentrations,' says Avery. Avery points out that Dr. Hayes' research is flawed due to the small sample size of the experiment. He cites several recent papers that have used sample sizes much larger and allowed the EPA full access to their research that contradict Hayes' research, finding no impact on feminization of males. Avery goes on to criticize Dr. Hayes for releasing his findings 'via press release orchestrated by environmental organizations' instead of doing research by the book without bias. 'We have to weigh one or the other. I don't think Dr. Hayes has really stepped up to the plate. He continues to do research that according to the EPA is 'insufficient' and 'scientifically flawed.'...They [the EPA] also complain that Dr. Hayes would not share his raw data.' Finally Avery addresses Dr. Hayes research directly, asking if his research is correct then frog populations in areas where atrazine has long been used would not be thriving as many are today. He also refers to a Yale University study which found frogs in urban areas having more of a feminization problem than rural areas, where atrazine is used.
