One of my sites was declined by google because the word "breast" was in one of my posts and they thought it was an adult site.
I think , you should try applying again after removing advertising medias like chitika , clicksor , etc that are already running on your blog. Stay away from this till your blog gets approved. Let me know, if this works for you.
Google has so many policies. Before you do anything, adwords or adsense, read all their policies very carefully first. My adwords account was banned because I didn't read their policy and did something wrong. Personally I hate google policies!
I think your blog have low traffic so adsense team rejected, Gain more traffic, daily 500+ visitors. Post quality content with relevant information.
