Niveles de materia particulada en la ciudad de Telde (Isla de Gran Canaria)

摘要

At the presente work levels corresponding to TSP and PM10 fractions of atmospheric particulate matter in Telde (Gran Canaria island) in relation with types of pollution sources in the area and comparing with values in different parts of the world,are presented .Experience was carry out between October 2002 and September 2003.A total of 54 samples (4 or 5 samples/month) were collec-ted.TSP concentrations ranged between 22.00 mu g centre dot m~(-3) and 225.00 ug centre dot m~(-3) with a mean value of 68.10 ug centre do m~(-3) PM10 concentrations ranged between 11.47 ug centre dot m~(-3) y 136.18 ug m~(-3) with a mean value of 32.13 ug centre dot m~(-3).Relationship PM10/TSP as an indication of different class of sources (natural and anthropogenic origins) was established and compared with other of different areas;mean value is 0.52 indicating an relative abundance of coarse particles on the ones forming PM10.
