Ammonia - Evaluation of the effects on reproduction, recommendation for classification

In the present report, the Health Council of the Netherlands reviewed ammonia. Eighty percent of all manufactured ammonia is used as fertilizer. A third of this is applied directly to soil as pure ammonia. The rest is used to make other fertilizers that contain ammonium compounds, usually ammonium salts. Ammonia is also used to manufacture synthetic fibres, plastics, and explosives. Furthermore, it is present in refrigeration systems. Many household cleaners and windowcleaning products also contain ammonia in the form of ammonium ions and it is further used in smelling salts.
