Abstract
Many cities, especially larger metropolises, parks are very important recreational areas where people usually have closer contact with flora. Therefore, the pollution level in the parks can have a greater effect on human health. Heavy metals are ubiquitous with the environment, as a result of both natural and anthropogenic activities, and humans are exposed to them through various pathways. Essentially, these areas are assumed to be less exposed to routine contaminants, but especially in metropolises, this assumption could prove false considering these areas are stuck within the confines of a city full of pollutant activity such as intense traffic. In this study; the relationships between heavy metal pollution levels (Cd, Cr, Cu, Ni, Pb, Zn) and the pH and electrical conductivity (EC) of soil samples were investigated from the parks on the Asian side of Istanbul. For this purpose, the most frequently visited 16 parks were selected as sampling sites. In the second part of the study, linear correlation is used for the data analysis.

In addition to air and water, living organisms need soil to survive
According to a report which is prepared by the Turkish Statistical Institute (TSI), the city has a total population of 13.6 million people and 64.7% of this population is living in the European side while the other 35.3% living in the Anatolian side [17]
Since most of the parks are isolated places when compared with general urban areas, it was intended to select the most probably contaminated parks in order to show the relationship of heavy metal concentrations
Summary
In addition to air and water, living organisms need soil to survive. Land is an important environmental component for the future of living organisms. The land is contaminated by different sources gradually. One of the most significant types of pollution on land is heavy metal pollution, this subject has become a focus point of environmental science. Among all of the researched heavy metal pollutants, Cu, Cd, Ni, Zn, Co and Pb become the most frequently examined, as they have a wide range of applications [1, 2, 3, 4]. Because of crop production over contaminated soils and contaminated pastures, heavy metals are carried up the food chain, and this process is significantly affecting all living organisms in the ecosystem – with human beings as no exception – in a dangerous manner [5]
