LEAD CONTAMINATION OF SNOW

SNOW FROM DISPOSAL SITES AND ALONG ROADS CONTAINED CONSIDERABLE LEAD DUE TO THE COMBUSTION OF LEADED GASOLINES BY AUTOMOBILES. A TABLE SHOWS THE DISTRIBUTION OF LEAD IN SNOW AND IN SNOW MELT AS A FUNCTION OF SAMPLING LOCATIONS IN OTTAWA. IN SPITE OF LEAD CONCENTRATION UP TO 4330 PPM IN THE SAMPLE SEDIMENT, THE HIGHEST CONCENTRATION IN THE FILTRATES WAS 0.21 PPM WITH THE AVERAGE, 0.04 PPM. THUS, THE DUMPING OF SNOW AWAY FROM WATER-COURSES INSTEAD OF DIRECTLY INTO THEM SIGNIFICANTLY REDUCES LEAD CONTAMINATION OF THE WATERS FROM THIS SOURCE. /DOT/
