The report gives results of field sampling on 47th Street in Kansas City, Missouri, during February and March 1993 to quantify the PM-10 emissions associated with use of rock salt (NaCl) for ice and snow control. A baseline test was conducted in September 1993. The emissions were determined using exposure profiling. The studies concluded that the sand from the antiskid material mixture that remained after the road had dried, constituted most of the silt loading and, therefore, the PM-10 emission impact. The rock salt, removed from the road mostly in the melting slush, contributed only a few percent to the residual silt loading.
