An American biologist and professor of Integrative Biology at the University of California, Berkeley, Tyrone Hayes believed he found a link between the reduction of size of the muscle surrounding the vocal cords of tadpoles and the herbicide atrazine. Hayes published his findings in the paper, ‘Hermaphroditic, demasculinized frogs after exposure to the herbicide atrazine at low ecologically relevant doses’, which caused a panic in the agrochemical world, as the paper showed that the herbicide was having an adverse effect on amphibians at concentrations below the accepted US safe contamination level in drinking water. The EPA, Eco Risk panel, and Syngenta all wanted to repeat Hayes’ findings, however, he resisted doing a duplicate study or answering questions about his data. Still to this day, 16 years later, he refuses to share his data with anyone outside his lab. The EPA could’t even use his 2002 PNAS (Proceedings of the National Academy of Sciences) paper as a baseline to study the effects of atrazine on amphibians, because it contains no data and did not meet the criteria for legitimate scientific work. Two independent labs in two countries, using the same methodology and 3,200 frogs, set out to see what impact atrazine had on amphibian reproductive health and found…..nothing. No sexual abnormality, no gender bending, no high pitch frogs, no gay frogs, nothing! When confronted with this data, Hayes simply dismissed it as “industry-funded”, obviously forgetting the fact that his own initial research was industry funded.
