Of heavy metals, a study with the spatial among distinct land-use types and pollution sources is very important. The spatial distributions partnership involving different land-use kinds and pollution sources is vital. The spatial of source contributions not only provides far more detailed heavy-metal source details, distributions of source contributions not merely gives extra detailed heavy-metal source it might also be conducive to getting trusted source apportionment results. details, it might also be conducive to getting reliable source apportionment results. Issue 1 accounted for 17.61 of the total contribution rate. Pb, Cd and Cu have been the Factor 1 accounted for 17.61 of the total contribution price. Pb, Cd and Cu had been major loading components, accounting for 80.84 , 66.65 andand 51.ten contributions, rethe key loading elements, accounting for 80.84 , 66.65 51.10 of of contributions, spectively.

The source of Ni is related to two may be the weathering approach, and also the supply of Cr is parent material [29]. Therefore, issue the weathering procedure, plus the source of Cr is parent material [29]. Therefore, aspect 2 is identified as the all-natural supply. identified as the natural source. the three things and created up 53.77 in the total contriFactor 3 was the largest of Factor three was the biggest on the three factors and for 67.58 and of the of the total, butions.
