Today I came across the following sentence in *Frankfurter Allgemeine Zeitung* article "[Die Mär von der Vergiftung der Welt](http://www.faz.net/aktuell/wirtschaft/aktivisten-monsanto-und-die-maer-vom-oekozid-14435524.html)": 

> 
> Manche der Monsanto\*\*-Ankläger sehen sich durch die
>  Agrarindustrialisierung in ihrer Existenz bedroht, andere haben
>  prinzipielle **Abscheu gegen** Chemikalien.
> 
> 
> 

In this sentence, the noun *Abscheu* (in English: revulsion, disgust) is used with preposition *gegen*. In [*Pons Dictionary*](http://en.pons.com/translate?q=Abscheu&l=deen&in=&lf=de) and [*Reverso Dictionary*](http://dictionary.reverso.net/german-english/Abscheu) it is stated, however that *Abscheu* is used with preposition *vor*. Are these prepositions interchangeable when used with *Abscheu* or is there a (subtle) difference in meaning?

\*\* [Monsanto Company](https://en.wikipedia.org/wiki/Monsanto) is a publicly traded American multinational agrochemical and agricultural biotechnology corporation. It is a leading producer of genetically engineered seed.
