A growing concern in agricultural and food chemistry is the presence of residues in food. Weuse many forms of organic chemicals in agriculture and food chemistry and there is growingconcern as to how safe these materials are. Choose an organic chemical used in agricultural offood chemistry and report on the functional groups contained in your compound, the uses of thecompound, and the safety of that compound. This research will require one or more outsidesources. Ensure all citations are in APA ...
