The chemical composition of rainfall in a city of Northern Spain

摘要: A study was carried out over a period of 4 yr on precipitation in Santander, coastal city with heavy rainfall the north Spain. An increase acidity found for latter studied, from April 1984 to 1985, possibly due change meteorology area this period. The correlations between ions themselves, and pollution SO2 suspended particulate matter, as well possible meteorological variables were analyzed using multiple linear regression method. influence mid- long-range transport pollutants also be important when air masses come highly industrialized zones both Central Europe neighboring Spanish regions, although contribution total acid deposition is less owing low frequency usually volume precipitation.
