ABSTRACT
Although the processing of fluid fertilizers is not normally associated with major pollution problems, the many operations involved [1] can give rise to significant levels of contamination that require control measures. There is no doubt that the inappropriate handling of solid raw materials may generate a great deal of dust and charge the air with unacceptable levels of particulate matter. Liquid and gaseous raw materials tend to be transferred by pipe, so they are readily contained. Nevertheless, the integrity of pipework may not be complete, so leakage into the environment is a possibility.
