Because of
greenhouses are high capacity of agricultural production areas, intense usage
of pesticides, fertilizers or water, it may cause heavy metal pollution. The
aim of this study was to determine total and extractable levels of heavy metals
(Ni, Cd, Cr, Pb, Cu, Zn) of soil samples in greenhouse in Tokat provience,
Turkey. For this purpose, total 60 soil samples were collected from the 0–20 cm
topsoil layer and 20-40 cm subsoil layers in different 30 greenhouses. The
levels of heavy metals were determined by using inductively couple plasma optic
emission spectrometry (ICP OES) according to standard methods. Heavy metal
levels were found as Zn (81.8-331.5), Ni (10.0- 18.4), Cr (51.2- 289.8),
Pb (BDL-54.3), Cu (118.3-178), Cd (BDL- 0.001) mg kg−1 in 0-20 cm topsoil and
Zn (81.2-290.9), Ni (1.16- 196.8), Cr (53.2- 284.2), Pb (0.49-30.8), Cu
(87.8-175.1), Cd (BDL- 0,001) mg kg−1 in 20-40 cm subsoil layers.
DTPA-extractable contents of heavy metals were found as Zn (1.2-10.5), Ni (BDL-
0.55), Cr (0-0.018), Pb (0.87-1.03), Cu (1.02-7.99), Cd (0.009-0.058) mg kg−1
in 0-20 cm topsoil and Zn (0.89-15.3) Ni (0- 0.52), Cr (BDL-0.019), Pb
(0.008-2.16), Cu (1.12-11.2), Cd (0.007-0.083) mg kg−1 in 20-40 cm subsoil
layers.
