Abstract

      Forty two surface soil samples (0-30cm depth) from four location, highly polluted with industrial wastes in Egypt, were analyzed for the total Pb and Cu,  DTPA-extractable Pb and Cu.  The values of total Pb ranged from 37 to 249 ug/g soil   with mean value 136 ug/g soil. The values of   total Cu ranged from 26 to 245 ug/g soil   with mean value 119 ug/g soil. The minimum, maximum and mean values of  DTPA-extractable  were 2.4 and  34.6 and 14.91 ug/g soil  for lead, respectively and 1.7  ,32.8 and 15.06 ug/g soil  for copper, respectively.       Multiple regression equations were derived to find the relationships between:  First total Pb and other variables, second between total Cu and other variables, third between DTPA-extractable Pb and other variables and forth between DTPA-extractable Cu and other variable, the more variables added to the equation, little improvement in R-sq was observed.       Factor analysis was used to combine variables Clay%; pH; EC; CaCO3%; OM%; Pb(T); Pb(av) ,Cu(T); Cu(av)   as soil analysis  parameters into homogeneous groups. For the first agglomeration, the final partition shows the lowest similarity of 49.2% between two associations cluster {Clay% }and cluster  { pH; EC; OM%; Pb(T); Pb(av); CaCO3%}.While there is evident with the highest similarity of  96.3%  when  joining cluster. {Pb(T)} with cluster {Pb(av). For the second agglomeration, the highest similarity of 90.4% was found when joining cluster {Cu(T)}with cluster{ Cu(av)  }; while the lowest similarity of 52.172% between two associations cluster {Clay% }and cluster { pH; EC; OM%; Cu(T); Cu(av); CaCO3%}.For the third agglomeration, there is evident with the highest similarity of  96.3%  when  joining cluster {Pb(T) ug/g}; and cluster{ Pb(av) ug/g}. While the lowest similarity of 52.17%  was found between cluster{Clay} and cluster {pH, OM ,EC;  Cu(T); Cu(av) , Pb(T) , Pb(av), CaCO3}.
