Plants serve as the greatest interface between soil and underground water/atmosphere, and they face many stress factors throughout their lives. Micro nutrients necessary for the development of the plant (bone (Cu), zinc (Zn), iron (Fe) etc.) with heavy metals in the soil (cobalt (Co), bullet (Pb), cadmium (Cd) etc.) They have phytotoxic effects on specific concentrations and depending on their resolutions. These metals are included in the ecosystem in many different ways. In the beginning of the industrial derived metals come Cu, Nickel (Ni), Pb, Zn and Cd. The most important problem is the possibility of these metals entering the nutritional chain. In this study, the effects of Zn (5, 10, 20, 40, 80, 160 mg L-1), Cd (0, 1, 2, 4, 8, 16, 32 mg L-1) and Pb (0, 2, 4, 8, 16, 32, 64, 128, 256 mg L-1) metals in different concentrations were studied on the plant’s marul (Lactuca sativa L.) seed grinding, root and body extension, and plant’s biomass. After all, Zn and CD applications have reduced seed grinding. The application of Pb has inhibited the grain in low concentrations while increasing the grain in high concentrations. In each of the three metals exposure has been determined to have inhibition in root and body extension, and root inhibition is more sensitive than the body. While no major change has been observed in plant dry masses compared to control, significant decreases have been observed in age biomasses, especially in Zn exposure.
