From May 1992 to August 1993, rain water and snow samples taken from the Kanazawa suburbs were analyzed to determined the metal concentration and pH and to clarify the distribution of metals. A negative correlation between the quantity of precipitation and quantity of trace elements was noted for some metal elements, and it is speculated that they originated from soil, sea water, or artificial contamination.
