TABLE 4.

Zinc, lead, and cadmium concentrations (mg×kg^–1 dry soil) as well in roots and leaves of T. repens originating from the metal-polluted waste heap (WH) and the non-polluted reference (R) area.

	Soil			Root			Leaves
Study area	Zn	Pb	Cd	Zn	Pb	Cd	Zn	Pb	Cd
WH	50,008 ± 9,356^a	5,008 ± 998^a	490 ± 26.89^a	2,390 ± 553^a#	2,310 ± 118^a#	156 ± 12.14^a#	289 ± 56.47^a##	90.18 ± 15.89^a##	2.46 ± 0.45^a##
R	83.41 ± 11.39^b	9.86 ± 0.87^b	2.51 ± 0.21^b	52.46 ± 10.59^b#	2.88 ± 0.27^b#	0.26 ± 0.09^b#	39.36 ± 9.25^b##	0.52 ± 0.13^b##	0.01 ± 0.004^b##

Values were presented as means ± SD. Significant differences between values derived from the waste heap and reference areas were marked with different letters in a superscript. Significant differences between values received from the plant organs were marked with a number sign.
