Comparison of TPHs, Pb, As, and Cd concentration on the selected and control sites.

Parameter(mg/kg)	Selected site(Mean±S.E)	Control site(Mean±S.E)
TPHs	21 415±739	0.06±0.03
Pb	170.3±7.4	0.87±0.60
As	2.58±0.40	0.001±0.0
Cd	4.4±0.352	0.001±0

Different superscripts indicate significant difference (p < 0.05); similar superscripts indicate no significant difference (p > 0.05) in rows. SE: standard error.
