摘要：Pollutants in some manufactured ice were examined. The results measured about the pollutants such as NH3-N, NO2-N, NO3-N, Cl- and KMnO4-consumption were similar to those of other reports. SO42- and Pb, any servey in ice had not yet done, were more concentrated in ice than in original water. It is supposed that SO42- and Pb will come from bubbling air in the process of manufacturing.
