Title: Intersexuality and the Cricket Frog Linked to Pesticide Use
Abstract: Hermaphrodite Frogs Linked to Pesticide Use in a University of Illinois research report released March 2005. Scientists who compared frogs collected over the last 150 years have discovered a dramatic increase in hermaphrodites during the times when contamination from the pesticide DDT and other chlorinated compounds was widespread. Frogs with both male and female reproductive organs were rare in the 19th and early 20th centuries but more common during the 1950s, when the largest volumes of the chemicals were used. The findings, reported Tuesday in the journal Environmental Health Perspectives, add to the growing evidence that an array of pesticides and industrial chemicals can alter the sex hormones of animals.
