[Sanitary monitoring of the procedure of cleaning hopper cars after carriage of mineral fertilizers: ecological and hygienic aspects].
The paper presents the results of field tests of a hopper wagon after carriage of mineral fertilizers, which are further to be used for grain carriage. The tests were carried out step by steps: washings from the inner surface of the hopper wagon after carriage of mineral fertilizers in order to identify chemical substances and 12 hours after its abrasive sandblasting; washings from the inner surface, air sampling for filters and into absorbable solutions after completion of wagon blowing 2 hours after dust removal and 30 days after application of an Epovin enamel. It has been concluded that most ions as components of mineral fertilizers were found in the amounts greater than the maximum acceptable concentrations on the walls and inside the hopper wagon after mechanical cleaning of its inner surface of the wagon that carries minerals, as well as its subsequent abrasive sandblasting and blowing.
