For example, the same study had shown that in certain parts of Illinois that are more industrialized and had organochlorine peptides there was a larger proportion of intersex frogs. In the case of Illinois, this was in the northeast. However, more environmentally friendly regions, like southern Illinois, had a more diverse frog population. [22]
