Abstract
The GIS (Geographic Information System) mapping technique was employed to study the behavior of the seasonal changing in concentration for 5 (Zn, Cu, Fe, Cd and Pb) polluting elements in (2000, 2004, 2008 and 2012) in Borollus Lake Northern Coast East of Alexandria, Egypt. The spatial interpolation method of inverse distance weighted (IDW) was applied to obtain the overall patterns of these elements (spatial distribution maps).
